Loading originals to copy or scan 31
To load originals into the ADF input tray
Note ADF capacity is up to 50 sheets of 75 g/m2 (20-pound) media (depending on the thickness of the media), or until the ADF input tray is full. The minimum size for media in the ADF is 127 x 127 mm (5 x 5 inches). For smaller sizes use the flatbed scanner. The maximum size for media in the ADF is 215.9 mm wide by 381 mm long (8.5 x 15 inches). Make sure the flatbed scanner is free of media. Close the flatbed scanner cover and put the top end of the original media stack into the ADF input tray, with the media stack face up and the first page to be scanned, copied, or faxed on top of the stack. Slide the media stack into the ADF until the media does not move any farther. Adjust the media guides until they are snug. The document is now ready to be copied or scanned.

Understanding print quality settings
Print quality settings affect how light or dark the print is on the page and the style in which the graphics are printed. You can also use the print quality settings to optimize the print quality for a specific media type. See Optimizing print quality for media types for more information.
You can change the settings in the printer properties to accommodate the types of jobs you are printing. The following settings are available depending on the printer driver you are using:
Best Quality (ProRes 1200): This prints at 1200 dpi (dots per inch) and provides the best print quality. Faster Printing (FastRes 1200): The resolution is rendered differently so that the job can print faster. This is the default setting. 1200 dpi 600 dpi 300 dpi Custom: This prints the same as the Faster Printing setting, but you can change the scale patterns. EconoMode (Save Toner): Text is printed using less toner. This setting is useful when you are printing drafts.
Changing the resolution can change the formatting of your text.
To temporarily change print quality settings
To change the print quality settings only for the current software applications use, access the properties through the Print Setup menu in the application you are using to print. See Changing settings from your computer for more information.
To change print quality settings for all future jobs
You can access print quality settings by selecting Printers from the Windows Start menu, then accessing the properties for the product. The settings are on the Finishing tab (Windows) under Print Quality settings in the printer properties. To view the details of each setting, click Details. For Macintosh OS 9.1 select the Imaging Options screen.
To enable EconoMode (save toner)
An excellent way to extend the life of your print cartridge is by using EconoMode. EconoMode uses substantially less toner than normal printing. The printed image is lighter, but it is adequate for printing drafts or proofs. To enable EconoMode, access the printer properties. On the Finishing tab (Windows) or the Imaging Options screen (Macintosh OS 9.1) under Print Quality, select EconoMode. For Macintosh OS X use the Device Configuration Utility: 5 Note Open the HP LaserJet Director. Choose Tools. Choose Device Configuration. Choose the Print tab. On the Print Quality menu, choose to turn EconoMode On.
See Changing settings from your computer for instructions on enabling EconoMode for all future jobs.

Understanding scanning methods
The HP LaserJet 3300 series product offers four ways to scan an item:
Scan from the product: Start scanning directly from the product using the control panels scan buttons. The start scan and scan to buttons can be programmed to scan to a destination. For more information, see Scanning from the products control panel. Scan from the HP LaserJet Director: Use the HP LaserJet Director for one-touch scanning to specific programmed destinations, such as saving to a file, sending it to e-mail, or converting it to document files. Scan from the HP LaserJet Scan Control Viewer: Use the HP LaserJet Scan Control Viewer to customize your scan and send it to a selected destination. For more information, see Scanning with the product software. The three ways to access the HP LaserJet Scan Control Viewer are: Click Scan from the Document Manager. Click Scan from the HP LaserJet Director. Select Scanner from the program group in the Start menu.
Scan from TWAIN-compliant software: If you are using Microsoft Windows 95 and want to scan documents, you must use a TWAIN-compliant application. For all other operating systems, using TWAIN-compliant software is optional. For more information, see Scanning with TWAIN-compliant software.
To learn about optical character recognition (OCR) software, see Scanning with OCR. Scan buttons are not available on the 3310 model.
Scanning from the products control panel
Note If you purchased the HP LaserJet 3310 product, scanning from the control panel is not available. To scan with the 3310, see Scanning with the product software. Use the following instructions to scan directly from your HP LaserJet 3300 series product:
To scan from the products control panel using the start scan button To use the scan to button via USB or parallel connection To use the scan to button via network connection To reprogram the scan to button destinations To reprogram the start scan button

To e-mail scanned files in an alternative mode
You can use an alternative mode to send a document in e-mail in any of the following situations:
You do not have a compatible e-mail program. The E-mail button does not appear on the HP LaserJet Director. You do not have access to the HP LaserJet Director. Load the originals to be scanned face up in the ADF input tray and adjust the media guides. OR Lift the flatbed cover and load the original to be scanned face down on the flatbed scanner with the top left corner of the document located in the lower right corner of the glass. Gently close the lid. Use the HP LaserJet Director or other software to scan the document to the desktop or HP LaserJet Scan Control Viewer. Save the file in the format you want. Open your e-mail program, attach the file as you normally would, enter an address, and click Send.
Scanner resolution and color
If you are printing a scanned image or copying an image and the quality is not as you expected, you might have selected a resolution or color setting in the copier/scanner software that does not match your needs. Resolution and color affect scanned and copied images in the following ways:
Image clarity Texture of gradations (smooth or rough) Scan and copy time File size
Resolution is measured in dots per inch (dpi) while color, grayscale, and black and white define the number of colors possible. You can adjust the scanner hardware resolution up to 600 dpi. The software has the ability to perform an interpolated resolution up to 9600 dpi. You can set color and grayscale at 1 bit (black and white) or 8 bit (256 levels of gray) to 24 bit (true color). The resolution and color guidelines table lists simple tips that you can follow to meet your scanning and copying needs.
Setting the resolution and color to a high value can create large files that take up disk space and slow the scanning or copying process. It is important that you first determine how you are going to use the scanned image. Color and grayscale images achieve the best resolution when scanned from the flatbed scanner rather than the ADF.

Supported media sizes (printer)
The following are the supported media sizes:
Minimum: 76 x 127 mm (3 x 5 inches) Maximum: 216 x 356 mm (8.5 x 14 inches)
Guidelines for using media
For best results, use conventional paper. Make sure that the paper is of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, and curled or bent edges. If you are unsure about what type of paper you are loading (such as bond or recycled), check the label on the package of paper. Some paper causes print quality problems, jamming, or damage to the printer. Note Do not use letterhead that is printed with low-temperature inks, such as those used in some types of thermography. Do not use raised letterhead.
The printer uses heat and pressure to fuse toner to the paper. Make sure that any colored paper or preprinted forms use inks that are compatible with the printer temperature (200 C or 392 F for 0.1 second).
Common media problems table

Symptom

Poor print quality or toner adhesion, or problems with feeding.

Problem with paper

Too moist, too rough, too smooth, or embossed. Faulty paper lot.

Solution

Try another kind of paper between 100 and 250 Sheffield and 4 to 6% moisture content.
Dropouts, jamming, or curl.

Stored improperly.

Store paper flat in its moisture-proof wrapping. Use lighter paper.
Increased gray background shading. Excessive curl, or problems with feeding.

Might be too heavy.

Too moist, wrong grain direction, or short-grain construction.
Use long-grain paper. Print using the straight-through output path.
Jamming, or damage to printer. Problems with feeding.

Cutouts or perforations.

Do not use paper with cutouts or perforations. Use good quality paper.

Ragged edges.

Labels
When selecting labels, consider the quality of the following factors:
Adhesives: The adhesive material should be stable at 200 C (392 F), the printers maximum temperature. Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets that have spaces between the labels, causing serious jams. Curl: Prior to printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in any direction. Condition: Do not use labels with wrinkles, bubbles, or other indications of separation. Never use a sheet of labels that has already been run through the printer.

Transparencies

Transparencies must be able to withstand 200 C (392 F), the printers maximum temperature.
Guidelines for using media 139

Envelopes

Envelope construction

Card stock guidelines

If the card stock curls or jams, print using the straight-through output path. Set margins at least 2 mm (0.08 inch) away from the edges.
Selecting media for the ADF

ADF specifications

Input capacity: The ADF holds up to 50 sheets of flat 60 to 90 g/m (16- to 24-pound) plain paper. Media size: Only use plain paper within the following size ranges: Minimum: 127 mm x 127 mm (5 x 5 inches) Maximum: 215.9 mm x 381 mm (8.5 x 15 inches)
Use the flatbed scanner for copying and scanning if the media is fragile, thin, or thick. The flatbed scanner provides the best copy and scan quality. The ADF is recommended for plain paper copying, scanning, and faxing (faxing can be done only from the ADF).

Storing print cartridges

Do not remove the print cartridge from its package until you are ready to use it. The shelf life of a print cartridge in an unopened package is approximately 2.5 years. The shelf life of a print cartridge in an opened package is approximately 6 months. CAUTION To prevent damage to the print cartridge, do not expose it to light.
HP LaserJet print cartridges 147
Print cartridge life expectancy
The life of the print cartridge depends on the amount of toner that your print jobs require. When printing text at 5% coverage, the standard print cartridge (C7115A) lasts an average of 2,500 pages. The extended life print cartridge (C7115X) lasts an average of 3,500 pages. This assumes that you set the print density to 3 and turn EconoMode off (these are the default settings).
Recycling print cartridges
To reduce landfill waste, Hewlett-Packard has adopted a recycling program for empty print cartridges. A postage-paid shipping label is inside the new HP LaserJet print cartridge box. Since 1990, the HP LaserJet Print Cartridge Recycling Program has collected more than 25 million used HP LaserJet print cartridges that otherwise might have been discarded in the worlds landfills. To join this recycling effort, follow the instructions provided in the new print cartridge box. To install a new HP print cartridge, see To install a print cartridge or follow the instructions included in the print cartridge box. See the recycling information on the print cartridge box and the HP Printing Supplies Environmental Program Information included in the print cartridge box.

Saving toner

To save toner, select the EconoMode option in your printer properties settings. While in EconoMode (Save Toner), the printer uses less toner on each page. Selecting this option will extend the life of the print cartridge and reduce your cost per page, but it will reduce print quality. See Print cartridge life expectancy for more information.

DIMMs (memory or font)

Power/Status light blinking amber
Your print server has developed a fault. Fixing this fault requires assistance from HP Jetdirect technical support; see the support flyer that came with your product for information on contacting HP.
10/100 link OK? (10 light or 100 light ON solid green?)
The link lights, the 10 light and the 100 light, indicate whether the print server can initiate a network link at the right speed with your hub, switch, or router. One of the link lights, either the 10 light or the 100 light, should be ON solid green (bright green in color and glowing continuously, not blinking) to indicate a valid link with the hub/switch/router. If there is not a valid link, both the 10 and 100 lights will be off. If one of the print servers link lights is ON solid green, continue with Check the print servers I/O status. If neither of the print servers link lights is ON solid green, or if you are not sure what to look for, follow the instructions below to start evaluating the link status of the print server.
Troubleshooting overview 193
Is one of the link lights ON (solid green)?
Check the link lights on your print server; these lights are built into the network connector. One of the link lights, either the 10 light or the 100 light, but not both, should be ON solid green, to indicate a valid network connection.

Link lights OFF

Try the steps below and make any necessary corrections.
Make sure that the network cable is connected securely to the print server. Check that the network cable is plugged securely into the hub/switch/router, and that the connection is set to the correct network speed. (If your hub/switch/router is set to configure its link speed automatically, try to configure it manually for 10 Mbps or 100 Mbps only. After changing this setting, you may need to cycle power to the print serverunplug the print servers power cable and then plug it in again.) Check that the LINK light is ON for the port on the hub/switch/router to which the print server is connected. Your network cable may be faulty. Try a different cable. If the light still does not come on, try a different port on the hub/switch/router.
Did these steps turn ON one of the link lights?
If yes, continue with Check the print servers I/O status. If no, your print server has a problem that requires assistance from HP Jetdirect technical support; see the support flyer that came with your product for a list of technical support telephone numbers.
Check the print servers I/O status
Check the I/O status of the print server by following these steps:
Print a Jetdirect configuration page. To print the page, press the test button on the print server. If the configuration page does not print, see Configuration page does not print for help in getting it to print. On the configuration page, check that the print server reports its status as I/O Card Ready. The Status entry is the first entry in the General Information section, in the upper left portion of the page. See Interpreting the configuration page for more details on the configuration page.

Chapter contents 73

Basic functions
This chapter presents a functional overview of the HP LaserJet 3300mfp series. The following systems are discussed: formatter functions scanner and ADF functions and operation printer functions and operation ECU (engine controller unit) system/power system image formation system paper-feed system (printer) and document-feed system (document scanner) LIU (fax) functions and operation The full product consists of: the scanner (flatbed/ADF) the printer the line interface unit (LIU). Each of these three systems brings its own characteristic functionality to the product: scanning, printing, and telecommunications respectively. In addition, these systems combine forces to complete the functionality offering of the product. The scanner and printer work together to make copies. The scanner and LIU work together to send faxes. The LIU and printer work together to receive faxes. Operation sequences of the printer are controlled by the ECU. Operation sequences of the LIU and document scanner are controlled by the formatter.

Standard Boot Process

When the product is unplugged or the power is off, the firmware code is stored on the formatter in two blocks. The first block of code is an executable boot block (about 64K of code). The second block of code is a compressed version of the product control code. When the product is powered up, the boot block decompresses the product control code and stores it in RAM. Then the product performs a full startup with the control code running from RAM.

Product startup messages

The LED display contains different messages depending upon the progress of the boot process:
Table 13. Product startup messages Message Cause
(Blank display for many seconds after power on). Boot block failure.
The flash memory requires a DIMM recovery of the firmware code (see Chapter 6). The flash memory requires a DIMM recovery of the firmware code (see Chapter 6). Wait until Ready display. Begin using product.

Moving cursor HP display. The product is starting up. Product startup is complete and the product is ready for action.

Formatter system 77

One bank of Non-Volatile RAM (NVRAM) stores parameters. Dynamic random access memory (DRAM) provides temporary storage of the product program code plus copy, scan, and print data.
Parallel interface or Universal Serial Bus interface
The formatter receives incoming data through its bidirectional ECP or USB interface. These interfaces provide high-speed, two-way communication between the product and the host, allowing you to change product settings and monitor product status from the host computer.

Control panel

The control panel configuration varies by model in the HP LaserJet 3300mfp series. For example, only the HP LaserJet 3330mfp has the fax buttons. The HP LaserJet 3300mfp series control panel consists of: up to six groups of buttons to control fax, copy, scan, and configuration functionality (with all six on the HP LaserJet 3330). a 2 x 16 LCD display for display of status, menus, and messages. up to two front panel status lights (one by the cancel button and one by the fax/send button on the HP LaserJet 3330).

LIU (fax) functions and operation 103

Hook switch control

Another signal coupled optically is the hook switch control. This is a signal from the formatter that causes an optoisolator on the LIU to go active (making an open circuit into a short circuit). When shorted, the circuit is drawing DC current from the central office and is considered on-hook. When open, there is no DC current and the state is considered to be off-hook. For pulse dialing, the optoisolator is toggled on and off with a particular timing sequence to generate pulses recognized as dialing digits by the central office of the telephone company.

Ring detect

Another optically coupled signal on the LIU is ring detect. Ring detect is a combination of voltage levels and cadence (time on and time off). They both must be present to have a valid ring detected by the product. The LIU works with the firmware to determine if an incoming signal is an answerable ring. Circuits on the LIU detect a ring voltage above a certain threshold and a corresponding signal is passed to the formatter indicating the ring is above the threshold. The firmware then measures the time the signal is high and low and qualifies the cadence to decide if it is a valid ring.

Line current control

The DC current from the CO needs to have a path to flow from TIP to RING. Since it does not flow in the transformer, a path through some transistors and diodes (the DC hold circuit) acts like a simulated inductor (thus replacing the function of the transformer). This DC hold circuit is the main component of the voltage-current characteristic seen between TIP and RING. Two other functions of this block of circuits are the current limit and the SHUNT for Europe. Current limit basically maintains a constant current from TIP to RING once the voltage reaches around 50mA. The voltage can vary and the current will remain the same. The shunt function changes the impedance (the current-voltage characteristic) during certain special events such as pulse dialing and going on-hook. During such an event, the firmware tells the DSP on the formatter to activate SHUNT. A signal goes to the LIU through an optoisolator (optically coupled) which changes the state of some transistors so
104 Chapter 4 - Operational overview
that the board has a linear current characteristic (normally its current limited). This allows more current to flow to the network as required by these special events.
Billing (metering) tone filters
Switzerland and Germany provide high frequency AC signals on the phone line for the purpose of billing customers. LC filters are provided on the European LIU's to prevent these billing signals from adversely affecting the data path and the DC hold circuit. An additional filter in the cable (for certain countries) may in some cases supplement these LC filters. These billings signals are not used in the US, so these filters are not present on the US LIU.

Removal and replacement strategy
This chapter documents the removal and replacement of fieldreplaceable units (FRUs) only. Replacement is generally the reverse of removal. Occasionally, notes are included to provide directions for difficult or critical replacement procedures.
Remove the power cord before attempting to service the product. If this warning is not followed, severe injury can result as well as damage to the device. Certain functional checks during troubleshooting must be performed with power supplied to the product. However, the power supply should be disconnected during removal of any parts. Never operate or service the product with the protective cover removed from the laser/scanner assembly. The reflected beam, although invisible, can damage your eyes. The sheet metal edges of the product can be sharp. Use caution when working on the product.
Some parts are electrostatic discharge (ESD)-sensitive. Always perform service work at an ESD-protected workstation. To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread pattern, then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping screw-hole becomes stripped, repair the screw-hole or replace the affected assembly. Always remove the print cartridge before removing or replacing parts. See Print cartridge on page 110.
