If You Cannot Make Clear Prints

Faint Prints

If the machine is not used for a long period of time or you change the color drum unit, the ink on the
drum might dry causing print quality to deteriorate. To solve this problem, use Quality Start mode. See
page 123 "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 page 207 "Cleaning the Exposure Glass
Cover".
Check the exposure glass and clean it if dirty. See page 206 "Cleaning the Exposure Glass".
Check the sheet of the optional ADF and clean it if dirty. See page 207 "Cleaning the ADF".
• If black lines or stains still appear on prints even following the cleaning procedures above, please
contact your service representative.

Dirty Background

If the background of prints is dirty, the drum unit might be dirty.
• If ink gets into contact with eyes, wash eyes immediately with running water. Consult a doctor if
necessary.
• Keep ink and ink containers out of reach of children.
• If ink is ingested, induce vomiting by drinking a strong saline solution. Consult a doctor
immediately.
