Guidelines for Using Paper
For best results, use conventional 20 lb (75 g/m2) paper. Make sure 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 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.
Table 1-14. Guidelines for Using Paper Symptom
Poor print quality or Toner adhesion. Problems with feeding. Dropouts, jamming, curl.
Problem with Paper
Too moist, too rough, too smooth, or embossed; faulty paper lot. Stored improperly.
Solution

Increased gray background shading. Excessive curl. Problems with feeding.
Too heavy.
Too moist, wrong grain direction or short-grain construction. Cutouts or perforations.
Jamming, damage to printer.
Do not use paper with cutouts or perforations. Use quality paper.
Problems with feeding.
Ragged edges.
1-16 Printer Description
Note
Do not use letterhead paper 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's temperature (400° F or 205° C). Avoid using paper that has already been used in a printer or copier. Do not print on both sides of envelopes, transparencies, or labels.

1-18 Printer Description
Labels
CAUTION To avoid damaging the printer, use only labels recommended for use in laser printers. If you have problems printing labels, use Tray 1 and open the Rear Output Bin. Never print on the same sheet of labels more than once.
Label Construction
When selecting labels, consider the quality of each component:
q
Adhesives: The adhesive material should be stable at 400° F (205° C), the printer's maximum temperature. Arrangement: Only use labels with no exposed backing between them. Labels can peel off of sheets that have spaces between the labels, causing serious jams. Curl: Prior to printing, labels must lie flat with no more than 0.5 in (13 mm) of curl in any direction. Condition: Do not use labels with wrinkles, bubbles, or other indications of separation.
q
q
q
Transparencies
Transparencies used in the printer must be able to withstand 400° F (205° C), the printer's maximum temperature. For best results, close the Rear Output Bin to print transparencies to the Top Output Bin. CAUTION To avoid damaging the printer, use only transparencies recommended for use in laser printers. If you have problems printing transparencies, use Tray 1.
Paper Specifications 1-19
Envelopes
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:
q
Weight: The weight of the envelope paper should not exceed 28 lb (105 g/m2), or jamming may result. Construction: Prior to printing, envelopes should lie flat with less than 0.25 in (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 in (76 by 127 mm) to 8.5 by 14 in (216 by 356 mm). Sizes in the optional envelope feeder: From 3.5 by 6.3 in (90 by 160 mm) to 7 by 10 in (178 by 254 mm).
q
q
q
q
If you do not have an optional envelope feeder, always print envelopes from Tray 1. If envelopes wrinkle, try opening the Rear Output Bin.
1-20 Printer Description
Envelopes with Double Side Seams
Some envelopes have vertical seams at both ends of the envelope, rather than diagonal seams. This style of envelope may be more likely to wrinkle. When using envelopes with double side seams, be sure the seam extends all the way to the corner of the envelope as illustrated below.
Acceptable
Unacceptable
Figure 1-3
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 (400° F (205° C)) and pressure in the printer. The extra flaps and strips might cause wrinkling, creasing, or jams.
Paper Specifications 1-21
Envelope Margins
The following table gives typical address margins for a Commercial #10 or DL envelope. Table 1-16. Envelope Margins Type of Address
Return Address Delivery Address
Top Margin
0.6 in (15 mm) 2 in (51 mm)
Left Margin
0.6 in (15 mm) 3.5 in (89 mm)
Note
For the best print quality, position margins no closer than 0.6 in (15 mm) from the edges of the envelope.
Envelope Storage
Proper storage of envelopes helps contribute to good print quality. Envelopes should be stored flat. If air is trapped in an envelope, creating an air bubble, then the envelope may wrinkle during printing.
1-22 Printer Description
Card Stock and Heavy Paper
Many types of card stock can be printed from Tray 1, including index cards and postcards. Some types of card stock perform better than others because the construction is better suited for feeding through a laser printer. For optimum printer performance, do not use paper heavier than 53 lb (199 g/m2) in Tray 1 or 28 lb (105 g/m2) in other trays. Paper that is too heavy might cause misfeeds, stacking problems, paper jams, poor Toner fusing, poor print quality, or excessive mechanical wear. Note Printing on paper heavier than 53 lb may be possible if the tray is not filled to capacity, and paper with a smoothness rating of 100-180 Sheffield is used.
Card Stock Construction
q
Smoothness: 36-53 lb (135-199 g/m2) card stock should have a smoothness rating of 100-180 Sheffield. 16-36 lb (60-135 g/m2) card stock should have a smoothness rating of 100-250 Sheffield. Construction: Card stock should lie flat with less than 0.2 in (5 mm) of curl. Condition: Make sure card stock is not wrinkled, nicked, or otherwise damaged. Sizes: Use only card stock within the following size ranges: · minimum: 3 by 5 in (76 by 127 mm) · maximum: 8.5 by 14 in (216 by 356 cm)
q
q
q
Note
Before loading card stock in Tray 1, make sure it is regular in shape and not damaged. Also, make sure the cards are not stuck together.
Card Stock Guidelines
q
If cards curl or jam, try printing from Tray 1 and opening the Rear Output Bin. Set margins at least 0.08 in (2 mm) away from the edges of the paper.

Toner Safety
Note Toner may stain clothing. Skin and clothing are best cleaned by removing as much Toner as possible with a dry tissue, then washing with cold water. Hot water causes Toner to melt and permanently fuse into clothing. The Toner Cartridge/Drum Material Safety Data Sheet (MSDS) can be obtained by contacting the HP LaserJet website at: http://www.ljsupplies.com/planetpartners/datasheets.html. If you do not have access to the Internet, call the U.S. HP FIRST fax-on-demand service at (800) 231-9300. Use index number 7 for a listing of the Toner Cartridge/Drum Material/Chemical Safety Data Sheets. Note To get documents from HP FIRST by fax, you must use a Group 3 fax machine.

Service Approach
Repair of the printer normally begins with use of the printer's internal diagnostics in conjunction with the troubleshooting procedures in Chapter 7. Once a faulty part is located, repair is generally accomplished by assembly level replacement of Field Replaceable Units (FRUs). Some mechanical assemblies may be repaired at the subassembly level. PCA component replacement is not supported by Hewlett-Packard.

Toner Cartridge Information
The Toner Cartridge is designed to simplify replacement of the major "consumable" parts. The Toner Cartridge contains the printing mechanism and a supply of Toner. At 5% page coverage, a Toner Cartridge will print approximately 6,000 or 10,000 pages (depending on the model installed). However, a Toner Cartridge should print more pages if regularly printing pages with less coverage, such as short memos. If EconoMode is used full-time, it is possible that the Toner supply will outlast the mechanical parts in the Toner Cartridge. The cartridge may print fewer pages if routinely printing dense print. Note For best results, always use a Toner Cartridge before the expiration date stamped on the Toner Cartridge's box.
Refilled Toner Cartridges
While Hewlett-Packard does not prohibit the use of refilled Toner Cartridges during the warranty period or while the printer is under a maintenance contract, it is not recommended for the following reasons:
q
Repairs resulting from the use of refilled Toner Cartridges are not covered under Hewlett-Packard warranty or maintenance contracts. Hewlett-Packard has no control or process to ensure that a refilled Toner Cartridge functions at the high level of reliability of a new HP LaserJet Toner cartridge. Hewlett-Packard also cannot predict what the long term reliability effect on the printer is from using different Toner formulations found in refilled cartridges. The print quality of HP LaserJet Toner Cartridges influences the customer's perception of the printer. Hewlett-Packard has no control over the actual print quality of a refilled Toner Cartridge.
q
q
Recycling Toner Cartridges
In order to reduce waste, Hewlett-Packard offers a recycling program for used Toner Cartridges. Cartridge components that do not wear out are recycled. Plastics and other materials are recycled. HP pays the shipping costs from the user to the recycling plant. For each cartridge returned, HP donates one U.S. dollar to be shared by the Nature Conservancy and the National Wildlife Federation. To join this recycling effort, follow the instructions inside the Toner Cartridge's box.
