Card stock and heavy media
You can print many types of card stock from the paper 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 printer performance, do not use paper heavier than 157 g/m
(42-pound). Paper that
is too heavy might cause misfeeds, stacking problems, paper jams, poor toner fusing, poor print
quality, or excessive mechanical wear.
Selecting media for the ADF 141
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 to 180 Sheffield.
