Paper Feed Tray Set-Up

Paper Feed TraySetting up the Paper Feed Tray

1. Open the Paper Feed Tray

2. Adjust the Feed Tray Paper Guides to the widthof the paper and the load printing paper.

Important!Do not mix printing paper of different sizes.

3. Set the Paper feed pressure.

(NORMAL) Standard paper

(CARD) Thick paper such as drawingpaper or smooth paper

Adding or Replacing PaperIf you want to add paper or use paper of a different size during printing, lowerthe Paper Feed Tray so that you can load the paper easily.

To lower the Paper Feed Tray, hold down the FeedTray Down button.

Important!Do not mix different paper sizes in the Paper FeedTray.

To prevent paper jams and misfeeds, follow the directions below:

• When using standard paper, set the Paper Feed Pressure Adjustment Leverto:“ “ (NORMAL).

• When using thick paper or smooth paper, set the Paper Feed PressureAdjustment Lever to “ “ (CARD).

• Slide the Feed Tray Paper Guides and Receiving Tray Paper Guides to fitthe paper size.

• Position the Paper Receiving Tray to fit the paper length.

• Use flat printing paper that is free of folds. If curled paper is unavoidable,place the printing paper so that the curl faces down.

• Printing paper tends to stick to the Drum surface if the top margin is toonarrow on the original or if the upper portion of the original uses a largeamount of ink. To solve this problem, lower the print position to provide awider top margin or reverse the top and bottom of the original. Then restartprinting from the beginning.
