Preventive Maintenance

Before performing any preventive maintenance, be sure to do the following:

1 Check the page count on the startup test. If the I/O board has been replaced or upgraded, check the repair log label affixed to the bottom of the printer or consult with the customer to determine page count.

2 Power off and unplug the printer.

3 Allow the fuser assembly rollers to cool.

4 Prepare your work area for electrostatic discharge prevention.

5 Spread a drop cloth under the work area to protect the floor from grease and spilled toner.

Caution: Never use an ammonia-based cleaner on the

LaserWriter II. These cleaners can discolor the plastic.

Caution: Before servicing the fuser rollers, make sure that the printer has been off at least 5 minutes to allow the fuser assembly to cool.

The service provider should clean the following items every 12 months or during each service call.
