HP LaserJet P3005 Printer series - Manual (Page 67)

Card stock construction
● Smoothness: 135-157 g/m 2 (36-42 lb) card stock should have a smoothness rating of
100-180 Sheffield. 60-135 g/m 2 (16-36 lb) card stock should have a smoothness rating of
100-250 Sheffield.
● Construction: Card stock should lie flat with less than 5 mm (0.2 inch) of curl.
● Condition: Make sure that the card stock is not wrinkled, nicked, or otherwise damaged.
Card stock guidelines
● Set margins at least 2 mm (0.08 inch) away from the edges.
● Use tray 1 for card stock (135 g/m 2 to 216 g/m 2 ; 50- to 80-lb cover).
CAUTION To avoid damaging the device, use only card stock recommended for laser printers.
To prevent serious jams, always use tray 1 to print on card stock and always use the
rear output bin.
Letterhead and preprinted forms
Letterhead is premium paper that often has a watermark, sometimes uses cotton fiber, and is available
in a wide range of colors and finishes with matching envelopes. Preprinted forms can be made of a
broad spectrum of paper types ranging from recycled to premium.
Many manufacturers now design these grades of paper with properties optimized for laser printing and
advertise the paper as laser compatible or laser guaranteed. Some of the rougher surface finishes, such
as cockle, laid, or linen, might require the special fuser modes that are available on some printer models
to achieve adequate toner adhesion.
NOTE Some page-to-page variation is normal when printing with laser printers. This variation
cannot be observed when printing on plain paper. However, this variation is obvious when printing
on preprinted forms because the lines and boxes are already placed on the page.
To avoid problems when using preprinted forms, embossed paper, and letterhead, observe the following
guidelines:
● Avoid using low-temperature inks (the kind used with some types of thermography).
● Use preprinted forms and letterhead paper that have been printed by offset lithography or
engraving.
● Use forms that have been created with heat-resistant inks that will not melt, vaporize, or release
emissions when heated to 200°C (392°F) for 0.1 second. Typically, oxidation-set or oil-based inks
meet this requirement.
● When the form is preprinted, be careful not to change the moisture content of the paper, and do
not use materials that change the paper's electrical or handling properties. Seal the forms in
moisture-proof wrap to prevent moisture changes during storage.
● Avoid processing preprinted forms that have a finish or coating.
● Avoid using heavily embossed or raised-letterhead papers.
