HP JetSend Communications Technology
HP JetSend is a technology from Hewlett-Packard that allows devices to communicate with each other simply and directly. HP JetSend is built into your printer, allowing it to receive information from any HP JetSend-enabled sending device anywhere on your network, whether it is in the same office or at a remote location. When you use the HP Fast InfraRed Receiver accessory, your printer can also receive information from any HP JetSend-enabled infrared device. Examples of HP JetSend sending devices include computers or laptops running HP JetSend software or scanners with HP JetSend built in. HP JetSend uses simple IP addressing between networked devices and cableless communication between infrared devices. Note HP JetSend software is not supported for Traditional Chinese, Simplified Chinese, Korean, and Japanese. To HP JetSend enable your computer or laptop, visit the HP JetSend website (www.jetsend.hp.com/products) for information on HP JetSend software. With the software, you will be able to exchange intra-company documents directly between two or more computers and between any HP JetSend enabled printers, without the problems of incompatible software applications or versions. HP JetSend software will allow your colleagues to create documents on their computers and send copies directly to this printer without any device-specific drivers or configuration difficulties. You can visit the HP JetSend website to learn which other devices are available to communicate easily and directly with your HP JetSend-enabled printer.

Paper Orientation

For Tray 1, load paper with the side-to-be-printed facing up, and the top, short edge toward the printer.

Figure 11

Paper Orientation for Tray 1
For all other trays, load paper with the side-to-be-printed facing down, and the top edge toward you.

Figure 12

Paper Orientation for All Other Trays

Printing Envelopes

With the optional envelope feeder, the printer will automatically feed up to 75 envelopes. To order an envelope feeder, see page 8. To print with the envelope feeder, see page 49. Many types of envelopes can be printed from Tray 1. (Up to 10 can be stacked in the tray.) Printing performance depends on the construction of the envelope. Always test a few sample envelopes before purchasing a large quantity.
Set margins at least 0.6 inch (15 mm) from the edge of the envelope. If you have problems printing envelopes, try opening the rear output bin.
When you print large numbers of envelopes and standard paper, for best printing performance print paper first, then envelopes. To alternate paper and envelopes, from the Configuration Menu in the printers control panel select SMALL PAPER SPEED=SLOW. WARNING! Never use envelopes with coated linings, exposed self-stick adhesives, or other synthetic materials. These items can emit noxious fumes. Envelopes with clasps, snaps, windows, coated linings, exposed self-stick adhesives, or other synthetic materials can severely damage the printer. To avoid jamming and possible printer damage, never try to print on both sides of an envelope. Before you load envelopes, make sure they are flat and not damaged or stuck together. Do not use envelopes with pressure-sensitive adhesive. (For envelope specifications, see page A-11.)

Caution

Loading Envelopes in Tray 1
1 Open Tray 1, but do not pull out the extension. (Envelopes feed best without the extension.) 2 Open the rear output bin and pull out the tray extension. (This reduces envelope curl and wrinkling.) 3 Load up to 10 envelopes in the center of Tray 1 with the side-to-be-printed facing up, and the postage-end toward the printer. Slide the envelopes into the printer as far as they will go without forcing them. 4 Adjust the guides to touch the envelope stack without bending the envelopes. Make sure the envelopes fit under the tabs on the guides.

Guidelines for Printing Custom-Size Paper
Do not attempt to print on paper smaller than 3 inches (76 mm) wide or 5 inches (127 mm) long. Set page margins at least.17 inch (4.23 mm) away from the edges. Feed short-edge first.
Setting Custom Paper Sizes
When custom paper is loaded, size settings need to be selected from the software application (the preferred method), the printer driver, or from the printers control panel. Note Settings in the printer driver and software application override control panel settings. (Software application settings override printer driver settings.)

X (front edge)

Feed short-edge first

Y (side edge)

Figure 16
Printing Custom-Size Paper
If the settings are not available from the software, set the custom paper size from the control panel: 3 From the Printing Menu set CONFIGURE CUSTOM PAPER=YES. From the Printing Menu, select inches or millimeters as the unit of measurement. From the Printing Menu, set the X dimension (the front edge of the paper) as shown in Figure 16. X can be 3 to 8.5 inches (76 to 216 mm). Set the Y dimension (the side edge of the paper) as shown in Figure 16. Y can be 5 to 14 inches (127 to 356 mm). If custom paper is loaded into Tray 1 and TRAY 1 MODE=CASSETTE, then set TRAY 1 SIZE=CUSTOM from the Paper Handling Menu in the printers control panel. See Customizing Tray 1 Operation on page 63.
If custom paper is loaded in the optional 500-sheet tray, be sure the paper size dial is set to Custom (page 39). 6 In the software, select Custom as the paper size. For example, if the custom paper is 8 by 10 inches (203 by 254 mm), set X=8 inches and Y=10 inches (X=203 millimeters and Y=254 millimeters).

Advanced Printing Tasks

This section will help you take full advantage of the printers features. These tasks are advanced because they require you to change settings from the printers control panel or the printer driver.
Using Features in the Printer Driver
When you print from a software application, many of the printers features are available from the printer driver. To access Windows printer drivers, see page 23. Note HP PCL 5e, PCL 6, PS, OS/2, UNIX and Macintosh drivers are slightly different. Check the drivers for available options. The PCL6 driver takes full advantage of the printers features. Settings in the printer driver and software application override control panel settings. (Software application settings override printer driver settings.)

Printer Collation

The Printer Collation feature, only available with 16 MB of RAM or a hard disk, allows multiple original prints (mopying) that provides you the following advantages:
Reduces network traffic Faster return to application All documents are original
See the application or printer driver help for specific steps.

RIP ONCE

If you frequently use several different kinds of paper, once trays are set up correctly, you do not have to check which paper is loaded in each tray before you print. This is especially helpful when the printer is shared, and more than one person loads or removes paper. Printing by type and size of paper is a way to be sure that print jobs always print on the desired paper. (Some printers have a feature which locks out trays, to prevent printing on the wrong paper. Printing by type and size of paper eliminates the need to lock out trays.) To print by type and size of paper, do the following: Be sure to adjust and load the trays correctly. (See the sections on loading paper, starting on page 34.) From the Paper Handling Menu in the printers control panel, select the paper type for each tray. If you are unsure what type you are loading (such as bond or recycled), check the label on the package of paper. Select the paper size settings from the control panel. Tray 1: If the printer has been set to TRAY 1 MODE=CASSETTE from the Paper Handling Menu, also set the paper size from the Paper Handling Menu. If custom paper is loaded, set the size of custom paper from the Printing Menu to match the paper loaded in Tray 1. To print custom-size paper, see page 57. Optional envelope feeder: Set the paper size from the Paper Handling Menu. Optional 500-sheet tray: Paper size settings are adjusted when paper is properly loaded into the printer and the paper size dial is set to match the paper size. If custom paper is loaded, set the size of custom paper from the Printing Menu to match the paper loaded in the tray. Set the paper size dial in the tray to Custom. To print custom-size paper, see page 57. Other trays: Paper size settings are adjusted when paper is properly loaded into the printer. (See the sections on loading paper, starting on page 35.)
From the software or printer driver, select the desired type and size of paper.
The type and size settings can also be configured from HP Web JetAdmin and HP JetAdmin software for networked printers. See the printer driver help. To print by type and size, it might be necessary to unload or close Tray 1, or set TRAY 1 MODE=CASSETTE from the Paper Handling Menu in the printers control panel. For more information, see page 63. Settings in the printer driver and software application override control panel settings. (Software application settings override printer driver settings.)

Supported Types of Paper

The printer supports the following types of paper:
plain letterhead prepunched bond color rough
preprinted transparency labels recycled card stock user-defined (5 types)

Deleting a Private Job

A private job is automatically deleted from the printers hard disk after the user releases it for printing, unless the user selects the Stored Job option in the driver. Note If you turn the printer off and then back on, all quick copy, proof and hold, and private jobs are deleted. A private job can also be deleted from the printers control panel before it is ever printed. Note Press [Menu] repeatedly until PRIVATE/STORED JOBS MENU appears. Press [Item] until the desired user name appears.
If you are using a Macintosh computer, the user name appears on the first line of the display and the job name appears on the second line of the display. After you have selected the desired user name using [Item], press [Value] until the desired job name appears. Press [Select] to select the job. PIN:0000 appears. Press [- Value +] to change the first number of the PIN, and then press [Select]. An * appears in place of the number. Repeat these steps to change the remaining three numbers of the PIN. COPIES=1 appears. Press [- Value] until DELETE appears. Press [Select] to delete the job.

Storing a Print Job

The user can download a print job to the printers hard disk without printing it. The user can then print the job at any time through the printers control panel. For example, a user may want to download a personnel form, calendar, time sheet, or accounting form that other users can access and print. To store a print job permanently on the hard disk, select the Stored Job option in the driver when printing the job.

Printing a Stored Job

The user can print a job stored on the printers hard disk from the control panel. Note Press [Menu] repeatedly until PRIVATE/STORED JOBS MENU appears. Press [Item] until the desired user name appears.
If you are using a Macintosh computer, the user name appears on the first line of the display and the job name appears on the second line of the display. After you have selected the desired user name using [Item], press [Value] until the desired job name appears. 5 Press [Select] to select the job name. COPIES=1 appears. Press [- Value +] until the desired number of copies appears. Press [Select] to print the job.

Deleting a Stored Job

Jobs stored on the printers hard disk can be deleted from the control panel. Note Press [Menu] repeatedly until PRIVATE/STORED JOBS MENU appears. Press [Item] until the desired user name appears.
Printing with the Optional HP Fast InfraRed Receiver
The HP Fast InfraRed Receiver enables wireless printing from any IRDA-compliant portable device (such as a laptop computer) to the HP LaserJet 4050, 4050 N, 4050 T, or 4050 TN printer. The printing connection is maintained by positioning the sending infrared (FIR) port within operating range. Note that the connection can be blocked by objects such as a hand, paper, direct sunlight, or any bright light shining into either FIR port. Note For more information, see the user guide that came with the HP Fast InfraRed Receiver.

Occasionally, paper can jam during printing. This section will help you to locate paper jams, properly clear them from the printer, and solve repeated paper jams. Many different messages can appear on the printers control panel display. Some messages tell the printers current status, such as INITIALIZING. Other messages require an action, such as CLOSE TOP COVER. Many of these messages are self-explanatory. However, some messages indicate a problem with the printer, or require further action or description. This section lists these types of messages, and tells what to do if a message persists. The printer should produce print jobs of the highest quality. If print jobs do not look sharp and clear, defects such as lines, specks, or smears appear on the page, or paper is wrinkled or curled, use this section to troubleshoot and solve the output quality problem. Before you can fix a printer problem, you must understand where the problem lies. Use the flowchart in this section to determine the printer problem, and then follow the corresponding troubleshooting suggestions. From the printer, you can print information pages, which give details about the printer and its configuration.

Chapter 4: Problem Solving

Clearing Paper Jams

If the printers control panel displays a paper jam message, look for paper in the locations indicated in Figure 19, then see the procedure for clearing the paper jam. You might need to look for paper in other locations than indicated in the paper jam message. If the location of the paper jam is not obvious, look first in the top cover area underneath the toner cartridge. When clearing paper jams, be very careful not to tear the paper. If a small piece of paper is left in the printer, it could cause additional jams. If paper jams are a recurring problem, see page 102. Note The top cover of the printer must be opened and then closed to clear a paper jam message.
Paper jams can occur at the following locations:

Figure 19

Paper Jam Locations
Output areas (top and rear). Go to page 99. Top cover area. Go to page 96. Toner cartridge area. Go to page 98. Input tray area (optional envelope feeder). Go to page 94. Input tray areas. Go to page 92. Optional duplexer. Go to page 100.
Loose toner might remain in the printer after a paper jam, but the toner should clear after a few sheets are printed.
Clearing Jams from the Input Tray Areas
Note To remove paper from the Tray 1 area, slowly pull the paper out of the printer. For all other trays, follow the steps below. (See the next page for clearing envelope feeder jams.) 1 Slide the tray out of the printer, and remove any damaged paper from the tray. 2 If the edge of the paper is visible in the feed area, slowly pull the paper down and out of the printer. (Do not pull the paper straight out, or it will tear.) If the paper is not visible, look in the top cover area (page 96). Note Do not force the paper if it will not move easily. If the paper is stuck in a tray, try removing it through the tray above (if applicable) or through the top cover area (page 96). Continued on the next page.

UNABLE TO MOPY JOB

An external paper handling device detected an unsupported paper size. The printer will go offline until the condition is corrected. If the requested paper size or type is not available, the printer asks if it should use another paper size or type instead. Press [- Value +] to scroll through the available types and sizes. Press [Select] to accept the alternate type or size. The RAM disk setting has been changed from the printers control panel. This change will not take effect until the printer reinitializes. If you change the mode of the external device, turn the printer off, turn the printer on and wait for the printer to reinitialize. The envelope feeder you are trying to install will not work for this printer. To order an envelope feeder for the printer, see page 8. Make sure the envelope feeder is installed correctly (page 50). A printer error has occurred that can be cleared by pressing [Go] in the printers control panel.

Remove toner cartridge and clear all paper from underneath the toner cartridge area. Caution Ensure all jammed paper is removed before opening and closing the top cover. Open and close the top cover to clear the message. If the message persists after all jams have been cleared, a sensor might be stuck or broken. Contact an HP-authorized service or support provider. (See the HP Customer Care Service and Support pages at the front of this users guide.) The printer received more data than can fit in its available memory. You might have tried to transfer too many macros, soft fonts, or complex graphics. Press [Go] to print the transferred data (some data might be lost), then simplify the print job or install additional memory (page C-1).

20 INSUFFICIENT MEMORY

PRESS GO TO CONTINUE
The data (dense text, rules, raster or vector graphics) sent to the printer was too complex. Press [Go] to print the transferred data. (Some data might be lost.) To print the job without losing data, from the Configuration Menu in the printer control panel, set PAGE PROTECT=ON, print the job, and then return PAGE PROTECT=AUTO. (See page B-14.) Do not leave PAGE PROTECT=ON; it might degrade performance. If this message appears often, simplify the print job. Too much data was sent to the EIO card in the specified slot (x). An improper communications protocol may be in use. Press [Go] to clear the message. (Data will be lost.) Check the host configuration. If this message persists, contact an HP-authorized service or support provider. (See the HP Customer Care Service and Support pages at the front of this users guide.) Too much data was sent to the parallel port. Check for a loose cable connection and be sure to use a high-quality cable (page 10). (Some non-HP parallel cables might be missing pin connections or might otherwise not conform to the IEEE-1284 specification.) This error can occur if the driver you are using is not IEEE-1284 compliant. For best results, use an HP driver that came with the printer (page 20). Press [Go] to clear the error message. (Data will be lost.) If this message persists, contact an HP-authorized service or support provider. (See the HP Customer Care Service and Support pages at the front of this users guide.) The connection has been broken between the printer and the EIO card in the specified slot. (Data loss might occur in this situation.) Press [Go] to clear the error message and continue printing.

Troubleshooting HP Fast InfraRed Receiver Problems (Continued) Item
The FIR status indicator turns off during transmission. PS print job will not print.
The connection might have been broken. Press [Cancel Job] to clear the printers memory. Then, reposition the portable device within the range of operation described in the user guide for the HP Fast InfraRed Receiver, and print the job again. Check the configuration in the PostScript Tab of Windows: check that Protocol is set to AppleTalk and Binary Data is not selected.
Communicating with an Optional HP JetDirect Print Server
If the printer contains an optional HP JetDirect print server, and you cannot communicate with the printer over the network, verify the operation of the print server. Check the HP JetDirect configuration page. (To print a configuration page, see page 134.) If the message, I/O CARD READY does not appear on the HP JetDirect configuration page, see the troubleshooting section of the HP JetDirect Print Server Software Installation Guide.
HP JetDirect 10/100TX print server
If the printer contains an optional HP JetDirect 10/100TX print server, check to see that the print server was able to link to the network: Check the link-speed indicators (10 or 100) on the print server. If both are off, the print server failed to link to the network. Check the HP JetDirect configuration page. The message LOSS OF CARRIER ERROR indicates that the print server failed to link to the network.
If the print server failed to link, verify that all cables are correctly connected. If all cables are correctly connected and the print server still fails to link, follow the steps below to reconfigure the print server: Turn off the printer and remove the HP JetDirect 10/100TX print server. Use jumpers P1, P2, and P3 to manually configure the print server for either 10 or 100 Mbps (megabits per second) link speed, and Full- or Half-duplex operation according to the table below:
Print Server Operation Autonegotiation Enabled 100 Half-duplex 100 Full-duplex 10 Half-duplex 10 Full-duplex Jumper P1 AUTO (not AUTO) (not AUTO) (not AUTO) (not AUTO) Jumper P100 (not 100) (not 100) Jumper P3 H (not H) H (not H)
Reinstall the print server. Verify that the configuration of the connecting network device (such as a 10/100TX network switch) matches. For example, to set the print server for 100TX Full-duplex operation, the port on the network switch must also be set for 100TX Full-duplex operation. Turn the printer off and back on and check the print server operation. If the print server fails to link, contact a local HP-authorized dealer or service representative.

Adjusting Memory Settings

Resource Saving

Resource Saving allows the printer to keep downloaded resources (permanent downloaded fonts, macros, or patterns) in memory when the printer language or resolution is changed. If you do not have an optional hard disk or flash DIMM for storing downloaded resources, you might want to change the amount of memory allocated to each language when downloading an unusually large number of fonts, or if the printer is in a shared environment. The minimum amount of memory that can be allocated to Resource Saving is 400 KB each for PCL and PS. To determine how much memory to allocate to a language: 1 From the Configuration Menu, set RESOURCE SAVE=ON (page B-15). You might need to add memory to the printer in order for this option to appear in the printers control panel. 2 Also from the Configuration Menu, choose either PCL MEMORY or PS MEMORY and change the setting to the highest value displayed. This amount will vary depending upon how much memory is installed in the printer. 3 Using a software application, download all the fonts you want to use in the selected language. 4 Print a configuration page (page 134). The amount of memory used by the fonts is listed next to the language. Round this figure up to the nearest 100 KB. (For example, if 475 KB are shown, 500 KB should be reserved.) 5 From the Configuration Menu, set PCL MEMORY or PS MEMORY to the value determined in step 4. 6 Repeat step 3. (You must download all fonts again. See the note below.) Note When you change the Resource Saving setting, all downloaded resources (such as fonts or macros) will need to be downloaded again, unless they are stored on an optional hard disk or flash DIMM.

I/O Buffering

To allow the computer to continue working without waiting for the print job to finish queuing, the printer uses a portion of its memory (an I/O buffer) to hold jobs in progress. (If I/O buffering is off, no memory is reserved for this function.) In most cases, it is best to let the printer automatically reserve memory for I/O buffering. (For each megabyte of memory added to the printer, 100 kilobytes are reserved.) To speed network printing, you might want to increase the amount of memory reserved for I/O buffering. To change the I/O Buffer setting: 1 From the I/O Menu, set I/O BUFFER=ON (page B-19). 2 Also from the I/O Menu, set I/O SIZE to the desired value. Note When you change the I/O Buffer setting, all downloaded resources (such as fonts or macros) will need to be downloaded again, unless they are stored on an optional hard disk or flash DIMM.
Installing EIO Cards/Mass Storage
Turn off the printer before installing the EIO card or mass storage device. See Figure C-1 for orientation and location of the EIO card or optional mass storage device, such as a hard disk. Use HP Resource Manager to manage fonts on a mass storage device (page 25). For more information, see the printer software help. HP is constantly introducing new software tools for use with your printer and accessories. These tools are available from the Internet free of charge. See page viii for how to visit the HP website for more information. After you have installed a new device, print a configuration page.
