Ricoh FW770 用户指南

If a puzzling or recurring problem occurs, check the following before
calling a service representative. It’s also a good idea to check the Do’s
and Don’ts section on page 36 to make sure the paper and originals
match what the copier can handle.
             

p

Is the main switch on?

p

Is the cord plugged in?

p

Did a breaker or a fuse blow out? 

p

Check the indicators on the control panel. If any of them are lit,
turn to page 28. Check that all covers and units are closed.

p

Is your paper creased, damp, or otherwise damaged? See the
Do’s and Don’ts section on page 36.

p

Are there visible bits of paper or other objects stuck in the ma-
chine? If there are, remove them.

p

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

p

Are copies too dark or too light? Adjust the density (see page 7).

p

Is the background dirty no matter what kind of original you are
copying? Make sure the exposure glass and platen are clean
(see page 27).
