Tips for Better Paper Feeding

To prevent paper jams and misfeeds, follow the directions below:
• When using standard or light-weight paper, set the Paper Feed Pressure Adjustment Lever to "NORMAL". Then
open all four Paper Arrangers. "p.31, "p.33
• When using thick paper (such as card stock), set the Paper Feed Pressure Adjustment Lever to "CARD", and open
the two inner Paper Arrangers. "p.31, "p.33
• When using slippery paper, set the Paper Feed Pressure Adjustment Lever to "CARD". "p.31, "p.33
• Slide the Feed Tray Paper Guides, Receiving Tray Paper Guides, and Paper Stopper to fit the paper size. "p.31
• Use flat printing paper that is free of folds. If curled paper is unavoidable, place the printing paper so that the curl
faces down.
• Paper may stick to the cylinder (drum) surface if the top margin is too narrow on the original or if the upper portion
of the original uses a large amount of ink. To solve this problem, lower the print position to provide a wider top mar-
gin or reverse the top and bottom of the original. Then restart printing from the beginning.

Storing Environment

Store printing paper in a level, dry area. Storing the paper in an excessively humid area can result in paper jams or
poor print quality.
After unpacking printing paper, keep the remaining paper wrapped and store it in a moisture-proof box. It is highly rec-
ommended to put silica gel in the paper storage box.
