If you Cannot Make Clear Prints
Faint Prints
If the machine is not used for a long period of time or you change the colour
drum unit, the ink on the drum might dry causing print quality to deteriorate.
To solve this problem, use Quality Start mode. See p.121 “Quality Start”.
If the print density is still too light even if you use Quality Start mode, remake
the master.
Black Lines/Stained Prints
Check the exposure glass cover and clean it if dirty. See p.204 “Cleaning the ex-
posure glass cover”.
Check the exposure glass and clean it if dirty. See p.204 “Cleaning the Exposure
Glass”.
Check the sheet of the optional ARDF and clean it if dirty. See p.205 “Cleaning
the Auto Document Feeder”.
Note
❒
If black lines or stains still appear on prints even following the cleaning pro-
cedures above, please contact your service representative.
