HP LaserJet M3027 Multifunction Printer series - Manual (Page 72)

NOTE: Choose transparencies in the printer driver. See Open the printer drivers on page 9 .
Card stock and heavy media
You can print many types of card stock from the input tray, including index cards and postcards. Some
card stock performs better than others because its construction is better suited for feeding through a
laser printer.
For optimum performance, do not use paper heavier than 199 g/m 2 (53 lb). Paper that is too heavy might
cause misfeeds, stacking problems, jams, poor toner fusing, poor print quality, or excessive mechanical
wear.
NOTE: You might be able to print on heavier paper if you do not fill the input tray to capacity and if
you use paper with a smoothness rating of 100-180 Sheffield.
In either the software program or the printer driver, select Cardstock (135 g/m 2 to 216 g/m 2 ; 50- to 80-
lb cover) as the media type, or print from a tray that is configured for heavy paper. Because this setting
affects all print jobs, it is important to return the product back to its original settings after the job has
printed.
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.
