Media Specifications
Introduction
You can use a variety of paper and other print media successfully with
the HP LaserJet 5/5M printer using the guidelines in this appendix.
Media that does not meet these guidelines may increase the incidence of
paper jams, cause premature wear to the printer, and contribute to repair
costs.
Before purchasing any media or specialized forms in quantity, make
sure it meets the media requirements specified in theHP LaserJet
Printer Family Paper Specification Guide (HP part number 5961-0920).
You may want to order this guide for your purchasing agent.
NoteHewlett-Packard neither warrants nor recommends the use of a
particular brand of print media. Media properties are subject to change
by the manufacturer and HP has no control over these changes.
It is possible that paper could meet all of the guidelines in this appendix
and still not print satisfactorily.  This might be due to improper handling,
unacceptable temperature and humidity levels in the room, or other
variables over which Hewlett-Packard has no control.
We recommend testing any paper before buying it in large quantities.
CautionUsing media outside these specifications may cause problems requiring
service.  This service is not covered by the Hewlett-Packard warranty or
service agreements.
ENMedia Specifications A-1 
						

							
Paper and Preprinted Forms
For best results, use conventional 20 lb (75 g/m2) xerographic 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.
Heavy Paper Stock
See the specific requirements given in Chapter 4 for each paper tray. Do
not use paper heavier than 36 lb (135 g/m2) from Tray 1 or 28 lb (105
g/m2) from the Tray 2; misfeeds, stacking problems, paper jams, poor
toner fusing, poor print quality, and excessive mechanical wear can
result. If you have the duplex option or the 500-sheet Tray 3, do not use
paper heavier than 24 lb (90 g/m
2).
Paper Guidelines
Follow these guidelines to avoid paper jams, poor print quality, or
damage to your printer:
•Do not use paper that is very rough, very smooth, or embossed.  Such
paper may cause feeding or print quality problems, and rough papers
may have poor toner adhesion.
•Do not use paper with cutouts or perforations.
•Do not use letterhead papers that are printed with low temperature
inks, such as those used in some types of thermography.
•The printer uses heat and pressure to fuse toner to the page.  Make
sure that any colored papers or preprinted forms use inks that are
compatible with this fusing temperature (392° F/200° C for 0.1
second).
•Keep paper stored in its moisture-proof wrapping to prevent changes
in moisture content, which may cause poor print quality, jamming,
and curl.
•To prevent feeding problems avoid paper with ragged cut edges.
•Use long-grain paper to prevent feeding problems and minimize curl.

Adhesive Labels
Use only labels recommended for use in laser printers.To purchase
labels, consult your HP authorized dealer or see the HP Support pages at
the front of this manual for more information.
Label Construction
When selecting labels, consider the quality of each component:
•Adhesives: The adhesive material should be stable at the 392° F
(200° C) temperatures encountered in the printer’s fusing process.
None of the adhesive should be exposed between the labels.
•Label arrangement: It is best to use labels with no exposed areas
between labels. If labels with exposed areas areused, arrange them
on the carrier sheet (the backing) so that they cover the entire page
with the exposed areas of the carrier sheet running lengthwise down
the sheet . Using label stock with spaces between labels often causes
labels to peel off during the printing cycle, causing serious jamming
problems.
•Label curl: Labels must lie flat with no more than 0.5 in (13 mm) of
curl in any direction.
•Poorly manufactured labels: Do not use labels with wrinkles,
bubbles, or other indications of delamination.
Label Guidelines
•Do not use labels that are separating from the backing sheet or that
are wrinkled or damaged in any way.
•Do not feed a sheet of labels through the printer more than once, the
label adhesive is designed for only one pass through the printer.

Overhead Transparencies
Overhead transparencies used in HP LaserJet 5 and 5M printers must be
able to withstand the 392° F (200° C) temperature encountered in the
printer’s fusing process.
CautionUse only overhead transparencies recommended for use in laser printers,
such as HP or 3M overhead transparency film.
Ordering Transparencies
To purchase transparency film, consult your HP authorized dealer or see
the HP Support pages at the front of this manual for more ordering
information.
Transparency Guidelines
•To avoid transparency curl, remove the transparency as it comes out
of the printer and set it on a flat surface to cool.
•To avoid transparencies sticking together, remove any transparencies
in the output bin before printing another transparency.

Envelopes
You can print many types of envelopes with your printer. Some
envelope styles perform better than others because their construction is
better suited to laser printing.
Envelope Construction
Envelope construction is very critical.  Envelope fold lines can very
considerably, not only between manufacturers but also within a box
from the same manufacturer. Successful printing on envelopes is very
dependent upon the quality of the media.
•Weight:The weight of the envelope paper should not exceed 28 lb
(105 g/m2) or jamming may result.
•Construction: Envelopes should lie flat with less than 0.25 in (6 mm)
curl.
•Manufacture: Make sure envelopes are not wrinkled, nicked, or
otherwise damaged.
•Sizes: Use only envelopes within the following sizes:
Tray 1
•Minimum: 3.5 x 6.3 in (90 mm x 160 mm)
•Maximum: 8.5 x 14.0 in (216 mm x 356 mm)
Envelope Feeder
•Minimum: 3.5 x 6.3 in (90 mm x 160 mm)
•Maximum: 7.0 x 10.0 in (178 mm x 254 mm)
Double Side Seam Envelopes
Double side seam construction has vertical seams at both ends of the
envelope rather than diagonal seams.  This style generally performed
adequately in Hewlett-Packard testing, but may be more likely to
wrinkle.
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 of the fusing rollers in the printer. The extra flaps and strips
may result in wrinkling or creasing, and may cause jamming.
A-6 Media SpecificationsEN 
						

							
CautionNever use envelopes with clasps, snaps, windows, coated linings,
self-stick adhesives, or other synthetic materials.  These items can
severely damage your printer.
Never try to print on both sides of an envelope.  Jamming and printer
damage can result.
Before you load envelopes in Tray 1, check to make sure they are
regular in shape and undamaged. Also, check to see that the envelopes
are not stuck together.
Envelope Storage
Proper storage of envelopes helps contribute to quality printing:
•Envelopes should be stored in an air-tight container, protecting the
envelopes from moisture.
•Envelopes should be kept flat when being stored.  Loose envelopes may
trap air inside. This could create an air bubble which would wrinkle the
envelope during printing.
Envelope Margins
The following table gives typical address margins for a Commercial #10
or DL envelope.  For envelopes of other sizes, adjust the margin settings
as desired.
Type of Address Top Margin Left Margin
Return Address 0.6 in (15 mm) 0.6 in (15 mm)
Delivery Address 2 in (51 mm) 3.5 in (89 mm)
NoteFor best print quality, position margins no closer than .5 inch (13 mm)
from the edges of the envelope.
Try to avoid printing over the area where the envelope’s three back flaps
meet.
