Supported paper and other media

Understand paper and print media use

This product supports a variety of paper and other print media in accordance with the guidelines in this user guide. Paper or print media that does not meet these guidelines might cause the following problems:
Poor print quality
Increased jams
Premature wear on the product, requiring repair
For best results, use only HP-brand paper and print media designed for laserjets or multiuse. Do not use paper or print media made for inkjet printers. Hewlett-Packard Company cannot recommend the use of other brands of media because HP cannot control their quality.
It is possible for paper to meet all of the guidelines in this user guide and still not produce satisfactory results. This might be the result of improper handling, unacceptable temperature and/or humidity levels, or other variables over which Hewlett-Packard has no control.
CAUTION: Using paper or print media that does not meet Hewlett-Packard's specifications
might cause problems for the product, requiring repair. This repair is not covered by the Hewlett-Packard warranty or service agreements.

Custom paper sizes

This product supports a variety of custom paper sizes. Supported custom sizes are sizes that are within the minimum- and maximum-size guidelines for the product but are not listed in the supported paper sizes table. When using a supported custom size, specify the custom size in the print driver, and load the paper in a tray that supports custom sizes.

Special paper or print media guidelines

This product supports printing on special media. Use the following guidelines to obtain satisfactory results. When using special paper or print media, be sure to set the type and size in your print driver to obtain the best print results.
CAUTION: HP LaserJet printers use fusers to bond dry toner particles to the paper in very
precise dots. HP laser paper is designed to withstand this extreme heat. Using inkjet paper not designed for this technology could damage your printer.

Load media

The following sections describe how to load media into the different input trays.
CAUTION: If you try to print on media that is wrinkled, folded, or damaged in any way, a jam
might occur. See

Tray 1

Tray 1 is accessed from the front of the printer. The printer prints from tray 1 before attempting to print from other trays.
Clear jams on page 144 for more information.
Media guides ensure that the media is correctly fed into the printer and that the print is not skewed (crooked on the media). When loading media, adjust the media guides to match the width of the media that you are using.

Tray 2 and optional tray 3

Media guides ensure that the media feeds correctly into the printer and that the print is not skewed. Tray 2 has side and rear media guides. When loading media, adjust the media guides to match the length and width of the media that you are using.
ENWW Load media 9
NOTE: When you add new media, make sure that you remove all of the media from the
input tray and straighten the stack of new media. This reduces jams by preventing multiple sheets of media from feeding through the printer at one time.

Straight-through output path

Use the straight-through output path when printing envelopes, transparencies, heavy media, or any media that tends to curl when printed. If you open the straight-through output door before printing media from tray 1, tray 2, or optional tray 3, the media exits the printer through the straight-through output path.
NOTE: Printed media does not stack when you use the straight-through output path. The
media drops to the surface below unless you remove each sheet as it exits the printer.

Manual feed

You can use manual feed when printing mixed media. For example, you can use manual feed to print an envelope, then a letter, then an envelope, and so on. Load envelopes in tray 1 and load letterhead into tray 2.
To print using manual feed, open the printer Properties or Printer Setup, and then select Manual Feed (tray 1) from the Source Tray drop-down list. See
on page 17 or Configure the Macintosh printer driver on page 19 for instructions. After you have
enabled manual feed, press the Go button to print.

EconoMode

EconoMode is a feature that allows the printer to use less toner per page. Selecting this option may extend the life of the print cartridge and reduce your cost per page. However, it will also reduce print quality. The printed image is lighter, but it is adequate for printing drafts or proofs.
HP does not recommend the full-time use of EconoMode. If EconoMode is used full-time, it is possible that the toner supply will outlast the mechanical parts in the print cartridge. If print quality begins to degrade under these circumstances, you must install a new print cartridge, even if toner supply remains in the cartridge.
1. To use EconoMode, open the printer Properties (or Printing Preferences in Windows 2000
and XP). See
printer driver on page 19 for instructions.
2. On the Paper/Quality tab or the Finishing tab (the Paper Type/Quality tab for some Mac
drivers), select the EconoMode checkbox.
NOTE: Not all printer features are available in all drivers or operating systems. See the
printer Properties (driver) online Help for information about availability of features for that driver.

Laser/scanner system

The laser/scanner system receives video signals from the dc controller and the formatter and converts the signals into latent images on the photosensitive drum.
Figure 5-5 Laser/scanner system
66 Chapter 5 Theory of operation ENWW

Pickup/feed/delivery system

The pickup/feed/delivery system consists of several types of feed rollers and sensors. The dc controller uses two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as it passes through the printer. If media does not reach or pass each sensor within a specified time period, the dc controller determines that a jam has occurred and alerts the formatter.

Image-formation system

Laser printing requires the interaction of several different technologies, including electronics, optics, and electrophotographics, to provide a printed page. Each process functions independently and must be coordinated with the other printer processes. Image formation consists of the following five processes:
electrostatic latent-image formation
developing
transfer
fusing
drum cleaning
The five processes contain eight steps.
Figure 5-7 Image-formation system
Step 1: Primary charging
DC and AC biases are applied to the primary charging roller, which transfers a uniform negative potential to the photosensitive drum.
Figure 5-8 Primary charging
Step 2: Laser beam exposure
ENWW Image-formation system 69
The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum. An electrostatic latent image is formed on the drum where negative charges were neutralized.
Step 3: Developing
The developing cylinder comes in contact with the photosensitive drum to deposit toner onto the electrostatic latent image.
NOTE: The charges on the exposed area of the drum are shown as positive in Figure 5-9 Developing on page 70. The charges are actually negative, but they are more positive than
the charges on the developing cylinder.
Figure 5-9 Developing
Toner acquires a negative charge through friction from the developing cylinder and the blade. When the negatively charged toner comes in contact with the drum, the toner adheres to the electrostatic latent image. The image on the drum becomes visible because of the toner.
Step 4: Transfer
The transfer charging roller, to which a dc positive bias is applied, imparts a positive charge on the print media. When the print media comes in contact with the photosensitive drum, the toner is transferred to the print media.
70 Chapter 5 Theory of operation ENWW
Figure 5-10 Transfer
Step 5: Separation
The elasticity of the print media causes its separation from the photosensitive drum. A static charge eliminator aids separation by weakening any electrostatic adhesion.
Figure 5-11 Separation
Step 6: Fusing
The dc negative bias applied to the fusing film strengthens the holding force of the toner on the print media and prevents the toner from scattering.
ENWW Image-formation system 71
Figure 5-12 Fusing
Step 7: Drum cleaning
The cleaning blade scrapes the residual toner off the photosensitive drum and deposits it into the waste toner case.
