Introduction

Every-Call Cleaning Procedure

Perform the every-call cleaning procedure every time the printer is serviced. When troubleshooting a printer problem, you may be directed to complete this procedure as you isolate 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.
