Media specifications

The printer accepts a variety of media, such as cut-sheet paper, including up to 100% recycled fiber content paper; envelopes; labels; transparencies; and custom-size paper. Properties such as weight, composition, grain, and moisture content are important factors that affect printer performance and output quality. Media that does not meet the guidelines that are outlined in this manual can cause the following problems:
Poor print quality
Increased jams
Premature wear on the printer, requiring repair
NOTE
CAUTION
Some media might meet all of media specifications and still not produce satisfactory results. Improper handling, unacceptable temperature and humidity levels, and other variables over which Hewlett-Packard has no control can affect print quality. Before purchasing large quantities of media, make sure that it meets the requirements that are specified in the user guide and in theHP LaserJet Printer Family Print Media Guide, which is available for download at http://www.hp.com/support/ljpaperguide. Always test paper before buying large quantities.
Using media that does not meet HP specifications can cause problems for the printer, requiring repair. This repair is not covered by the HP warranty or service agreements.

Printing and paper storage environment

Ideally, the printing and paper storage environment should be at or near room temperature, and not too dry or too humid. Remember paper is hygroscopic; it absorbs and loses moisture rapidly.
Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, while cold causes it to condense on the sheets. Heating systems and air conditioners remove most of the humidity from a room. As paper is opened and used, it loses moisture, causing streaks and smudging. Humid weather or water coolers can cause the humidity to increase in a room. As paper is opened and used it absorbs any excess moisture, causing light print and dropouts. Also, as paper loses and gains moisture it can distort. This can cause jams.
As a result, paper storage and handling are as important as the paper-making process itself. Paper storage environmental conditions directly affect the feed operation.
Care should be taken not to purchase more paper than can be easily used in a short time (about 3 months). Paper stored for long periods might experience heat and moisture extremes, which can cause damage. Planning is important to prevent damage to a large supply of media.
Unopened paper in sealed reams can remain stable for several months before use. Opened packages of media have more potential for environmental damage, especially if they are not wrapped with a moisture-proof barrier.
The paper storage environment should be properly maintained to ensure optimum printer performance. The required condition is 20° to 24°C (68° to 75°F), with a relative humidity of 45% to 55%. The following guidelines should be helpful when evaluating the paper's storage environment:
Paper should be stored at or near room temperature.
The air should not be too dry or too humid (due to the hygroscopic properties of paper).
The best way to store an opened ream of media is to rewrap it tightly in its moisture-
proof wrapping. If the printer environment is subject to extremes, unwrap only the amount of media to be used during the day's operation to prevent unwanted moisture changes.
ENWW Media specifications 13

Envelopes

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 105 g/m jamming might occur.
Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 inch)
curl, and should not contain air.
Condition:Envelopes should not be wrinkled, nicked, or otherwise damaged.
Temperature: You should use envelopes that are compatible with the heat and
pressure of the printer.
Size: You should use only envelopes within the following size ranges.
Minimum: 76 x 127 mm (3 x 5 inches)
Maximum: 216 x 356 mm (8.5 x 14 inches)
2
(28 lb) or
NOTE
Use only tray 1 to print envelopes. You might experience some jams when using any media with a length less than 178 mm (7 inches). This might be caused by paper that has been affected by environmental conditions. For optimum performance, make sure you are storing and handling the paper correctly (see envelopes in the printer driver (see
Printing and paper storage environment). Choose
Printer drivers).

Envelopes with double side seams

Double side-seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style might be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope as illustrated below.
1
2
1 Acceptable envelope construction 2 Unacceptable envelope construction

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 even jams and might even damage the fuser.
14 Chapter 1 Product Information ENWW

Envelope margins

The following gives typical address margins for a commercial #10 or DL envelope.
Type of address Top margin Left margin
Return address 15 mm (0.6 inch) 15 mm (0.6 inch)
Delivery address 51 mm (2 inches) 89 mm (3.5 inches)
NOTE
CAUTION
For the best print quality, position margins no closer than 15 mm (0.6 inch) from the edges of the envelope. Avoid printing over the area where the envelope's seams meet.

Envelope storage

Proper storage of envelopes helps contribute to print quality. Envelopes should be stored flat. If air is trapped in an envelope, creating an air bubble, then the envelope might wrinkle during printing.

Labels

To avoid damaging the printer, use only labels recommended for laser printers. To prevent serious jams, always use tray 1 to print labels and always use the rear output bin. Never print on the same sheet of labels more than once or print on a partial sheet of labels.
When selecting labels, consider the quality of each component:
Adhesives: The adhesive material should be stable at 200°C (392°F), the printer's
fusing temperature.
Arrangement: Only use labels with no exposed backing between them. Labels can peel
off sheets with 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.

Transparencies

Transparencies used in the printer must be able to withstand 200°C (392°F), the printer's fusing temperature.
CAUTION
ENWW Media specifications 15
To avoid damaging the printer, use only transparencies recommended for use in HP LaserJet printers, such as HP-brand transparencies. (For ordering information, see
Ordering parts and supplies.)
