Card stock and heavy paper
Many types of card stock can be printed from tray 1, 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 printer performance, do not use paper heavier than 200 g/m
2
(53 lb) in tray 1 or
120 g/m
2
(32 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.
Note Printing on heavier paper might be possible if the tray is not filled to capacity, and short-grain
paper with a smoothness rating of 100 to 180 Sheffield is used.
Card stock construction
Smoothness: Card stock should have smoothness in the range of 100 to 180 Sheffield.
Construction: Card stock should lie flat with less than 5 mm (0.2 inch) of curl. It should be
short-grain paper to improve feeding and reduce wear on the printer.
Condition: Make sure that card stock is not wrinkled, nicked, or otherwise damaged.
Sizes: Use only card stock within the following size ranges:
• minimum: 76 by 127 mm (3 by 5 inch)
• maximum: 216 by 356 mm (8.5 by 14 inch)
Before loading card stock in tray 1, make sure that it is regular in shape and not damaged. Also,
make sure that the cards are not stuck together.
Card stock guidelines
If cards curl or jam, try printing from tray 1 and opening the rear output bin.
Set margins at least 6 mm (0.24 inch) away from the edges of the paper.
