9-6 General Printer Maintenance
Every-Call Cleaning Procedure
Perform the every-call cleaning procedure every time the printer is serviced. When trou-
bleshooting a printer problem, you may be directed to complete this procedure as you iso-
late or correct the problem. If the procedure is not specifically called out, always complete
it before concluding the service call.
The every-call cleaning procedure begins by removing the major consumable supplies
from the printer. When the supplies are out, use a toner vacuum to vacuum the printer thor-
oughly. Clean each consumable supply, following the instructions listed in this section,
before returning it to the printer. Conclude the every-call procedure by running test prints
to confirm the print quality.
The location of all major printer supplies and instructions for their removal are outlined
later in this manual.
