CLEANING
Cleaning the scanner’s reading devices
When one or more vertical lines appear on transmitted copies or faxes, follow these steps:
Cleaning the printer
Dust, dirt and paper debris on the outer surfaces and inside the printer can interfere with printer
performance. Clean the printer regularly.
Remark : If the message "Clean Printer Press GO" appears after replacing the toner cartridge. Carry out the printer cleaning
procedures (corona, grille, etc.) described in the paragraph on Replacing cartridges, page 7-2 then press the GO
button. The message will disappear and the printer will be ready to print.
Caution - Use a soft cloth to clean the printer. Never use abrasive or corrosive detergents.
The fusing unit can become very hot during operation. To avoid injury - do not touch.
Wait for at least 10 minutes after the printer has been turned off and make sure that the fusing unit has
cooled before cleaning the interior of the printer.
