Paper Specifications
Card Stock and Heavy Paper
Note For best results, use the Standard Output Bin.
Many types of card stock can be printed from Tray 1, including 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 53 lb (199 g/
m
2
) in Tray 1 or 28 lb (105 g/m
2
) in other trays. Paper that is too heavy might
cause misfeeds, stacking problems, paper 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 paper with a smoothness rating of 100-180 Sheffield is used.
