Panasonic KX-P8420 Mode D’Emploi

 

Streaks or spots 

Most spots are caused by fingerprints or dust 
introduced into the printer while installing the color 
imaging unit or loading media. 

Make sure that the surface where you unpack the 
color imaging unit, paper, and transparencies is free 
of dust. Keep supplies in a covered area or a closed 
box.

Make sure that the color imaging unit stays covered 
until immediately before installing it in the printer. 
Exposure to light can damage the color imaging unit 
and will produce light streaks or faded prints.

Do not touch the right side or underside of the color 
imaging unit; fingerprints affect print quality.

Make sure that the paper or transparency film is 
clean.

Make sure that you handle the media on the outside 
edges to avoid fingerprints.

To get rid of fingerprint spots, print a few prints.

The back of the 
printed page 
appears dirty.

Toner particles have contaminated the transfer 
roller. This can happen if the printed image is larger 
than the media (for example, when printing on 
envelopes). Run 10-20 prints to clean the transfer 
roller.

The cleaning pad may get dirty with toner. Replace 
the cleaning pad. (See “Lists of Options and 
Supplies” in the Chapter 9 of Setting Manual.)

The print quality of 
a transparency is 
poor.

There is a defect on the coated surface of the 
transparency. Print on the other side.
