Troubleshooting

Others

If a puzzling or recurring problem occurs, check the following before calling a
service representative. It's also a good idea to check the 

 p.75 “Do's & Don'ts”

to make sure the paper and originals match what the copier can handle.

Absolutely Nothing Happens

• Is the main switch on?
• Is the power cord plugged in?
• Did a breaker or a fuse blow out?

Something Happens, but Set Paper or Paper Select Never Appear

• Check the indicators on the control panel. If any of them are lit, turn to 

 p.63.

Check that all covers and units are closed.

If Jams Occur Frequently

• Is your paper creased, damp, or otherwise damaged? 

 p.8.

• Are there visible bits of paper or other objects stuck in the machine? If there

are, remove them.

• Are you inserting the paper and original in straight? Always feed paper in

straight.

If Copies Look Wrong

• Are copies too dark or too light? Adjust the density (

 p.31).

• Is the background dirty no matter what kind of original you are copying?

Make sure the exposure glass and platen are clean (

 p.74).

• Is the image skewed? Make sure to insert the paper and the original straight

into the machine. If you have the original and Copy Guides (option), use
them.

White Spots Appear

• On the copy: try placing your copy paper with the other side facing up.
• At the leading edge: try placing your copy paper sideways.
• At the trailing edge: try giving a rising curl to the trailing edge. The curl

should go up, not down.
