Introduction

This document provides instructions for installing the printer maintenance kit for the HP LaserJet 4000 series printers. NOTE: The printer will not reset the maintenance counter back to 0 until it reaches 200,000 pages.

Required tools

Phillips #2 screwdriver Flat-blade screwdriver

Step 1: Fuser assembly

1. Turn the printer off. 2. Unplug the printer. WARNING: To avoid minor burns, wait 30 minutes for the fuser to cool before continuing with this procedure. 3. Remove the duplexer if installed. If it is not installed, remove the two duplexer slot covers by pulling away from the first. Figure 1: Removing the l eft and right duplex connector covers 4. Turn the printer so its rear cover faces forward. Open and extend the rear output bin. Figure 2: Removing the rear cover/rear output bin
5. Flex the tray slightly to remove one side at a time (see Figure 2, callouts 1 and 2). 6. Loosen the two screws in the fuser assembly. Figure 3: Loosening the captive screws for the fuser
7. Grasp the sides of the fuser assembly and pull it out of the printer. NOTE: When removing the fuser, the plastic cover can come off with the fuser remaining in the printer. 8. Install the new fuser assembly (align the left side first). Push the fuser assembly into the printer until the two tabs on both sides of the fuser assembly press against the plastic on the printer.
9. Replace the two screws. (Turn the screws counterclockwise until they click, then turn them clockwise to tighten.) 10. Replace the tray, inserting one side at a time. 11. Replace the duplexer slot covers or the duplexer. 12. Continue with the next section to remove and replace the transfer roller.

Step 2: Transfer roller

1. Put on gloves. CAUTION: To avoid damaging the transfer roller, never touch the transfer roller with bare hands. 2. Turn the printer so the front is facing forward. Figure 4: Removing the transfer roller
3. Open the top-cover and remove the toner cartridge. The transfer roller is underneath the toner cartridge. CAUTION: Do not touch the black rubber part of the roller. Skin oils on the roller can cause problems with print quality. 4. Using a flat-blade screwdriver, pry the right end of the metal shaft out of place, then the left end. NOTE: When the transfer roller is replaced, make sure the black collar is oriented properly, with the open end down. 5. Continue with the next section to remove and replace the Tray 1 pickup

roller.

Step 3: Tray 1 pickup roller
1. With the top cover still open, open Tray 1 and locate the roller. The Tray 1 pickup roller is in the center of the Tray 1 pickup assembly. 2. Grasp the envelope entrance cover and pull it straight away from the printer. 3. Pry open the blue latch on the roller. 4. Lift the roller out. NOTE: To replace the roller, make sure the pin in the roller lines up with the hole in the shaft. Figure 5: Detail of the Tray 1 pickup roller
6. Continue with the next section to remove and replace the separation rollers.
Step 4: Separation rollers
NOTE: Remove and replace the separation rollers and feed rollers on all trays except Tray 1. 1. Remove the tray. Open the door on the left, inside front of the tray. Figure 6: Removing the separation rollers
NOTE: The separation rollers are inside the paper trays. 2. Release the latch and lift the cover inside the tray. 3. Pinch the release at the left side of the roller and slide it off the shaft. 4. Replace new roller by sliding it on the shaft. Replace the cover.
CAUTION: Be sure that the roller slides on fully and clicks into place. Be sure to close cover completely by pressing until it snaps into place. 5. Continue with the next section to remove and replace the feed roller.

Step 5: Feed rollers

1. Move the printer to the edge of the work area for access to the feed roller area. NOTE: The following procedure is the same for all HP LaserJet 4000 series printers; there are two (2) rollers for the HP LaserJet 4000t and 4000tn and one roller for the HP LaserJet 4000 and 4000n. Figure 7: Removing the paper feed rollers (HP LaserJet 4000t and 4000tn shown)
2. Remove the tray from the feeder. The paper feed roller's are inside the feeder. 3. Pinch the release at the left side of the roller and slide it off the shaft. 4. Line up the new roller with the flat part of the axle. Slide the roller onto the axle and rotate until it locks into place. 5. Continue with the next section to reset the maintenance page count.
Step 6: Reset the maintenance page count
When all of the previous steps are complete, reset the maintenance page count. To reset the maintenance page count:
Press and hold down the left side of the ITEM and VALUE buttons on the control panel while turning the printer on. (The printer will not reset properly if the ITEM and VALUE buttons are held down on the right side.)
RESET MAINT COUNT appears in the display, followed by INITIALIZING. After a few seconds, READY will appear in the display. At this point, the printer's maintenance count has been reset.

Figure 4

The printer drivers provided on the compact disc must be installed to take full advantage of the printers features. The other software programs are recommended, but are not required for operation. See the ReadMe file for more information.
Network Administrators: HP JetAdmin should be installed only on the network administrators computer. Load all other applicable software on the server and all client computers. The most recent drivers, additional drivers, and other software are available from the Internet. Depending on the configuration of Windows-driven computers, the installation program for the printer software automatically checks the computer for Internet access to obtain the latest software. If you do not have access to the Internet, see the HP Support pages at the front of this users guide to obtain the most recent software.

Printer Drivers

Printer drivers access the printer features and allow the computer to communicate with the printer (via a printer language).
Check the ReadMe file provided on the compact disc for additional software included and supported languages. Certain printer features are available only from the PCL 6 driver. See the printer software help for availability of features.
Drivers Included with the Printer
The following printer drivers are included with the printer. The most recent drivers are available on the Internet. Depending on the configuration of Windows computers, the installation program for the printer software automatically checks the computer for Internet access to obtain the latest drivers.
PCL 5e Windows 3.1x Windows 95 Windows NT 3.512 Windows NT 4.0 Macintosh computer PCL 6 PS1
PPDs are included (page 19).
1. Hewlett-Packards PostScript Level 1 Emulation for Windows 3.1x; Level 2 Emulation for all other operating systems. 2. The PCL 5e driver is available from the Internet. (See the HP support pages at the front of this users guide.)
Within the computer installation program, select Typical Install to install the PCL 5e, PCL 6, and PS drivers and HP FontSmart. Select Custom Install to install only the software you prefer, or if you are a network administrator. Select Minimum Install to install only the PCL 6 driver for basic printing.

Additional Drivers

You can obtain the following printer drivers by downloading them from the Internet, or by requesting them from an HP-authorized service or support provider. (See the HP Support pages at the front of this users guide.)

HP PCL 5e, PCL 6, PS, and Macintosh drivers are slightly different. Check the drivers for available options. The PCL 6 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.)
Saving Printer Setup Information
Printer drivers allow you to save the printer settings you use most often as the default settings. For example, the driver might be set to print on letter size paper, portrait orientation, with automatic tray selection (from the first available tray). Some PCL 6 printer drivers will allow you to save printer settings for multiple kinds of print jobs. For example, you might want to create a Quick Set for envelopes, or for printing the first page of a document on letterhead. Look for the Quick Sets option in the Windows PCL 6 printer driver, or see the printer driver help for more information.
Printing with a Watermark
A watermark is a notice, such as Top Secret, printed in the background of each page in a document. Check the driver for available options.
Printing the First Page on Different Paper
From the PCL 6 printer driver, you can choose to print the first page of a document on different paper than the rest of the pages. Look for Use different paper for first page in the printer driver.
Printing Multiple Pages on One Sheet of Paper
You can print more than one page on a single sheet of paper. This feature is available in some printer drivers, and provides a cost-effective way to print draft pages. To print more than one page on a sheet of paper, look for a Layout or Pages Per Sheet option in the printer driver. (This is sometimes called 2-up, 4-up, or n-up printing.)

Figure 16

Sample Layout Options (1-up, 2-up, and 4-up)
Customizing Tray 1 Operation
Customize Tray 1 to fit your printing needs. The printer can be set to print from Tray 1 as long as it is loaded, or to print only from Tray 1 if the type of paper loaded is specifically requested. Set 64#;/1&'(+456 or 64#;/1&'%#55'66' from the Paper Handling Menu in the printers control panel. (Print speed might be slightly slower when printing from Tray 1 when 64#; /1&'(+456.)

Tray 1 Mode=First

If you do not keep paper in Tray 1 all the time, or you use Tray 1 only for manually feeding paper, keep the default setting, 64#; /1&'(+456 in the Paper Handling Menu.
64#;/1&'(+456 means that the printer usually pulls paper
from Tray 1 first unless it is empty or closed. You can still choose paper from other trays by specifically choosing another tray in the printer driver.

Tray 1 Mode=Cassette

64#;/1&'%#55'66' means the printer treats Tray 1 like the internal trays. Instead of looking for paper in Tray 1 first, the printer pulls paper either starting from the bottom tray upward (from the tray with the highest capacity to the tray with the least capacity), or the tray that matches type or size settings selected from the software.

6 Slowly pull any paper out of the duplexer. 7 Turn the duplexer over and remove any paper. 8 Insert the duplexer into the printer. 9 Open and close the top cover to clear the paper jam message. If a paper jam message persists, there is still paper in the printer. Look for paper in another location (page 64).
Solving Repeated Paper Jams
If paper jams occur frequently, try the following:
Check all the paper jam locations. A piece of paper might be stuck somewhere in the printer. (See page 64.) Check that paper is correctly loaded in the trays, that the trays are correctly adjusted for the loaded paper size, and that the trays are not overfilled. Check that all trays and paper handling accessories are completely inserted into the printer. (If a tray is opened during a print job, this might cause a paper jam.) Check that all covers and doors are closed. (If a cover or door is opened during a print job, this might cause a paper jam.) Try printing to a different output bin. The sheets might be sticking together. Try bending the stack to separate each sheet. Do not fan the stack. If you are printing from Tray 1, try feeding fewer sheets of paper or fewer envelopes at a time. If printing from the envelope feeder, make sure it is loaded correctly, pushing the bottom envelope in slightly farther than the top envelopes. If you are printing small sizes (such as index cards), make sure the paper is oriented correctly in the tray. Turn over the stack of paper in the tray. Also try rotating the paper 180. Check the quality of the paper being printed. Damaged or irregular paper should not be used. Use only paper that meets HP specifications. Do not use paper that has already been used in a printer or copier. (Do not print on both sides of envelopes, transparencies, or labels.) Check that the power supplied to the printer is steady, and meets printer specifications. Clean the printer. Contact an HP-authorized service or support provider to perform routine printer maintenance. (See the HP Support pages at the front of this users guide.)
Understanding Printer Messages
The following table explains messages that might display on the printers control panel. Printer messages and their meanings are listed in alphabetical order, with numbered messages following. If a message persists:
If a message persists requesting that you load a tray, or if a
message indicates that a previous print job is still in the printers memory, press [Go] to print or press [Cancel Job] to clear the job from the printers memory. If a message persists after performing all of the recommended actions, contact an HP-authorized service or support provider. (See the HP Support pages at the front of this users guide.)
Not all messages are described in this users guide (many are self-explanatory). Some printer messages are affected by the Auto Continue and Clearable Warning settings from the Configuration Menu in the printers control panel.

A temporary printing error occurred. Turn the printer off, and then turn the printer on. If this message persists, contact an HP-authorized service or support provider. (See the HP Support pages at the front of this users guide.) The printer detected an error. The numbers (ZZZZ) indicate the specific type of error. Turn the printer off, and then turn the printer on. Try printing a job from a different software application. If the job prints, go back to the first application and try printing a different file. (If the message only appears with a certain software application or print job, contact the software vendor for assistance.) If the message persists with different software applications and print jobs, record the numbers that appear (ZZZZ) and contact an HP-authorized service or support provider.

Paper Specifications

HP LaserJet printers produce excellent print quality. This printer accepts a variety of media, such as cut-sheet paper (including recycled paper), envelopes, labels, transparencies, and custom-size paper. Properties such as weight, grain, and moisture content are important factors affecting printer performance and output quality. The printer can use a variety of paper and other print media in accordance with the guidelines in this manual. Paper that does not meet these guidelines may cause the following problems:

To print sheets of labels, see page 42.

Transparencies

Transparencies used in the printer must be able to withstand 400 F (205 C), the printers maximum temperature. Close the rear output bin to print transparencies to the top output bin.
To avoid damaging the printer, use only transparencies recommended for use in laser printers. If you have problems printing transparencies, use Tray 1. To print transparencies, see page 44.

Envelope Construction

Envelope construction is critical. Envelope fold lines can vary considerably, not only between manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes depends upon the quality of the envelopes. When selecting envelopes, consider the following components:
Weight: The weight of the envelope paper should not exceed 2
28 lb (105 g/m ), or jamming may result. Construction: Prior to printing, envelopes should lie flat with less than 0.25 inch (6 mm) curl, and should not contain air. (Envelopes that trap air may cause problems.) Condition: Make sure envelopes are not wrinkled, nicked, or otherwise damaged. Sizes in Tray 1: From 3 by 5 inches (76 by 127 mm) to 8.5 by 14 inches (216 by 356 mm). Sizes in the optional envelope feeder: From 3.5 by 6.3 inches (90 by 160 millimeters) to 7 by 10 inches (178 by 254 millimeters).
If you do not have an optional envelope feeder, always print envelopes from Tray 1 (page 37). To print envelopes with the optional envelope feeder, see page 39. If envelopes wrinkle, try opening the rear output bin.
Envelopes with Double-Side-Seams
Double-side-seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style may be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope as illustrated below.

Acceptable

Unacceptable Figure A-1 Envelopes with Double-Side-Seams
Envelopes with Adhesive Strips or Flaps
Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives compatible with the heat and pressure in the printer. The extra flaps and strips might cause wrinkling, creasing, or jams.

Envelope Margins

The following table gives typical address margins for a Commercial #10 or DL envelope.

Serial Cable Specifications
Serial communication is simply the transmission of data one bit at a time. With just one bit to transmit at a time, data can be transferred with a simple electrical circuit consisting of only two wires. In this fashion, an eight-bit byte is transmitted one bit at a time and the individual bits are reassembled into the original byte on the receiving end. Bit transmission occurs from the least significant bit to the most significant bit.
Data Terminal Equipment (DTE) Data Communications Equipment (DCE) Asynchronous Communication Transmit on pin 2 and receive on pin 3. A printer is typically a DTE device. Transmit on pin 3 and receive on pin 2. A modem is typically a DCE device. Asynchronous communication or start/stop transmission is the concept of enclosing a character with a start and stop bit. The RS-232 specification defines the standards for asynchronous serial communication. Parity is a method of error checking at the bit level. Transmission is asynchronous, with one start bit, eight data bits and one stop bit. Parity is not used. HP LaserJet printers are DTE devices. Handshaking is the method by which the flow of data between two devices is controlled. The two methods of flow control that are used by HP LaserJet printers are software flow control, in which one device controls another by the content of the data, and hardware flow control, in which one device can control another by changing the voltage on a wire. Xon/Xoff is a data stream handshake protocol that sends Xon (DC1; 11 Hex) to the computer from the printers transmit data pin when the printer is able to accept data and sends Xoff (DC3; 13 Hex) when the printer is not ready for data. By definition, hardware handshaking is performed when two programs manipulate RS-232 control pins-DTR, DSR, RTS, and CTS to achieve a hardware-based form of flow control. In DTR/DSR handshaking, the sender asserts DTR (Data Terminal Ready) before sending the first character in a stream of data and waits for DSR (Data Set Ready) to be asserted in return. RTS/CTS handshaking is similar, but uses the Request To Send and Clear To Send pins rather than Data Terminal Ready. In either case, the sender delays transmitting data until the receiver is ready.

The pin outs for the computer end are typical pin numbers. The actual pin numbers for your computer may be different. Check the documentation for your computer to verify the proper pin outs. Pins not shown are not used by the printer.
You can perform most routine printing tasks from the computer through the printer driver or software application. This is the most convenient way to control the printer, and will override the printers control panel settings. See the help files associated with the software, or for more information on accessing the printer driver, see page 15. You can also control the printer by changing settings in the printers control panel. Use the control panel to access printer features not supported by the printer driver or software application.
