Introduction
Cleaning the D640 is an important factor in assuring optimum print quality. There are two
cleaning routines to follow:
• a short weekly cleaning routine that removes paper dust and stray toner particles from the
exterior of the printer.
• a more thorough internal cleaning procedure that should be performed when you replace
the drum.
Weekly Cleaning
Investing just a few minutes on your D640’s maintenance each week ensures minimum
downtime and maintains high print quality. Make sure someone is responsible for printer
maintenance. Perform the maintenance tasks at the recommended intervals.
Use these tools for cleaning:
• Cleaning cloths (supplied with the D640 printer)
•Rags
• Vacuum cleaner specially designed for picking up toner
• Blower brush (supplied with the D640 printer)
Note Turn the main power switch OFF before performing the weekly cleaning.
Caution Make sure that the toner vacuum is properly grounded before using it in the printer,
or the printer may sustain electrical damage. Refer to the vacuum’s operating manual.
