Supported types of paper
Use settings on the printer control panel to select the following types of paper and other print 
media.
●Plain
●Pre-printed
●Letterhead
●Transparency (see Transparencies)
●Prepunched
●Labels (see Labels)
●Bond
●Recycled
●Color
●Card stock (see  Card stock and heavy paper )
●Rough
●Envelope (for Tray 1 only)
Guidelines for using paper 
For best results, use conventional 75 g/m2 (20 lb) 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 lo ading (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. Do not use 
letterhead paper that is printed with low-temperature inks, such as those used in some types of 
thermography, and do not use raised letterhead. Coated papers and some transparencies can 
wrap around the fuser roller and possibly cause jams.
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 fusing temperature (392°F or 
200°C for 0.1 second).
Resolving issues with pape r and other print media
Use this section to resolve common problems with paper and other print media.
Symptom Problem Solution
Poor print quality or 
toner adhesion, 
problems with feeding Too moist, too rough, too 
smooth, or embossed; faulty 
paper lot Try another kind of paper, between 100 
to 250 Sheffield, 4% to 6% moisture 
content.
Dropouts, jamming, 
curl Stored improperly Store paper flat in its moisture-proof 
wrapping.
Increased gray 
background shading Too heavy
●Use lighter paper.
●Use the left output bin or the upper 
bin.
 
						

							ENWWPaper specifications161
Labels
To avoid damaging the printer, use only labels recommended for use in monochrome laser 
printers. Never print on the same sheet of labels more than once.
CAUTIONDo not print on both sides of labels, transparencies, envelopes, custom paper, or paper heavier 
than 216 g/m2 (58 lb bond). Damage to the printer and jams might result.
Label construction
When selecting labels, consider the quality of each component:
●Adhesives: The adhesive material should be stable at 200°C (392°F), the maximum fusing 
temperature of the printer.
●Arrangement:  Only use full-sheet labels. Labels  can peel off sheets with spaces between 
the labels, causing serious jams.
●Curl:  Prior to printing, labels must lay 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
CAUTION Transparencies used in the printer must be able to withstand 200°C (392°F), the maximum fusing 
temperature of the printer. To avoid damaging the printer, use only transparencies recommended 
for use in monochrome laser printers.
Do not print on both sides of labels, transparencies, envelopes, custom paper, or paper heavier 
than 216 g/m
2 (58 lb bond). Damage to the printer and jamming might result.
If you have problems printing transparencies, use optional Tray 1 and send them to the left output 
bin or the upper bin.
Envelopes
Note To print envelopes, use optional Tray 1 and print them either to the left output bin or to the upper bin.
Excessive curl
Problems with feeding Too moist, wrong grain 
direction or short-grain 
construction●Use the left output bin or the upper 
bin.
●Use long-grain paper.
Jamming, damage to 
printer Cutouts or perforations Use paper free of cutouts or 
perforations.
Problems with feeding Ragged edges Use supported types of paper.
Multi-sheet feeding Paper sticking together Remove paper, fan it, and reload paper.

							162Appendix A Specifications ENWW
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:  See Paper specifications  for supported envelope weight.
●Construction: Prior to printing, envelopes should lay fl at with less than 6 mm (0.3 inch) curl 
and should not contain air. (Envelopes that trap air can cause problems.)
●Condition:  Make sure envelopes are not wrinkled, nicked, or otherwise damaged.
●Sizes in optional Tray 1:  See Supported sizes of paper for input and output  for supported 
paper sizes.
Envelopes with adhesi ve 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 of the printer. The extra flaps and strips 
might cause wrinkling, creasing, or jams.
Envelopes with double-side-seams
Double-side-seam construction has vertical seam s 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.
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 might wrinkle during 
printing.
Card stock and heavy paper 
For optimum printer performance, do not use paper heavier than 216 g/m2 (58 lb bond) in 
optional Tray 1 or 199 g/m2 (53 lb) in other trays. Paper that is too heavy might cause misfeeds, 
stacking problems, jams, poor toner fusing, poor print quality, or excessive mechanical wear.
Card stock construction
●Smoothness:  135 to 216 g/m2 (36 to 58 lb bond) card stock should have a smoothness 
rating of 100 to 180 Sheffield.
●Construction:  Card stock should lay flat with le ss than 5 mm (0.2 inches) of curl.
●Condition: Make sure card stock is not wrinkled, nicked, or otherwise damaged.
●Sizes: See the sizes listed for  Optional Tray 1.
Note Before loading card stock in optional Tray 1, make sure it is regular in shape and not damaged. 
Also, make sure the cards are not stuck together.

Control-panel menus
Overview
The control-panel menu layout shows the menus that everyone uses while protecting the menus 
that administrators use. Everyone typically uses the first three menus in the list. Administrators 
and service technicians use the other items,  which can be protected with a personal 
identification number (PIN).
Perform most routine printing tasks from the computer by using the printer driver or the software 
program. These settings override the printer control-panel settings. See the Help files that are 
associated with the software, or, for more information about the printer driver, see  Gaining 
access to the printer drivers . If you cannot open a menu or use an item, it either is not an option 
for the printer or your network administrator has locked the function ( ACCESS DENIED MENUS 
LOCKED  appears on the control panel). See your  system administrator for more information.
NotePrinter driver and software commands override the printer control-panel settings.
At the control panel, you can print a menu map that indicates the layout and current settings of 
the control-panel menu items (see  Menu map).
Additional menu items can appear in the control panel, depending on the options that are 
installed in the printer.
This appendix contains information about all the items and possible values that are available on 
the printer. (Default values  are listed in the “Item” column.)
For more information about an optional HP output device, see the user guide that came with the 
device.
This appendix contains information about the following topics:
●The  Retrieve job menu  shows jobs that are stored on the device. Jobs are listed by user and 
job name. See  Using the job-storage features  for information about how to store jobs.
●The Information menu  provides a menu map that can be printed and other information 
pages.
●The  Paper handling menu  is used to set the media type (and the size, if it is not detected) for 
each tray.
●The  Configure device menu  allows administrators to set defaults, I/O ports, run diagnostics, 
and reset the printer.
The following submenus are available on the Configure device menu: Printing submenu
 System setup submenu
 I/O submenu
 Resets submenu
●Diagnostics menu  provides information about the printer that administrators and service 
technicians can use to define settings, see usage information, and troubleshoot problems.
●The  Service menu  allows service technicians to monitor printer status and to provide 
appropriate assistance during a service call.
