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 optimal product performance, do not use paper heavier than 199 g/m
2
(53 lb) in
Tray 1 or 105 g/m
2
(28 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 may 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.
Short-grain paper improves feeding and reduces wear on the product.
● Condition: Make sure 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 inches)
• maximum: 216 by 356 mm (8.5 by 14 inches)
Before loading card stock in Tray 1, make sure it is regular in shape and not damaged.
Also, make sure the cards are not stuck together.
Card stock guidelines
● If cards curl or jam, try printing from Tray 1 and opening the rear output slot.
● Set margins at least 6 mm (0.24 inch) away from the edges of the paper.
