SOLVING REPEATED PAPER JAMS

1. Check to see that paper is correctly loaded in the trays, and that all width guides are correctly set (not skewed).

2. Ensure that the paper tray is set for the size of paper installed and that the tray is not overloaded with paper.

3. Try turning over the stack of paper in the tray. If you are using letterhead paper, try printing from Tray 1.

4. Do not use previously printed paper or torn, worn, or irregular paper

5. Check the paper specifications. (If paper is outside of the recommended specifications, problems may occur.)

6. When duplexing, the printer rolls paper under Tray 3 and causes a jam. Pull Tray 3 out of the printer completely and remove any paper from under the tray. Insert Tray 3 back into the printer.

7. Printer may be dirty. Clean the inside of the printer with a dry, lint-free cloth.

8. Check that the correct paper size is installed.

9. Check that all damaged or jammed paper is removed by pulling it out of the printer.
