3-8 OPERATION GUIDE
Cleaning the Printer
The following parts must be cleaned each time the toner container and
waste toner box are replaced:
• Main charger wire
• Main charger grid
• Advanced beam array lens
• Registration roller
In addition to this, it is recommended that the main charger wire and
registration roller are cleaned periodically at least once a month.
If lines, etc., appear on printed copies, the printouts appear dirty, or faint or
blurred printouts are produced, clean the advanced beam array lenses.
Cleaning the Main Charger Unit
The main charger units need to be cleaned periodically as they get
contaminated after long usage. Each main charger unit comprises two
main parts — the wire and the grid — which should be cleaned separately
as explained below.
There are 4 main charger units, one for each toner container. When
performing the cleaning procedure, be sure to clean the main charger unit
that corresponds to color of the toner container that was replaced. The
following example explains the procedure to clean the main charger unit for
the black toner container.
