Normal printer use means 6,000,000 printing carriage cycles. Under normal usage conditions, it will be approximately 5 years before the printer needs maintenance. If the printer is used more than the normal usage conditions, then it will need maintenance service much more frequently.

One of the EEROM counters is assigned to counting the number of carriage cycles as well as the usage cycles of other major components. When the printer exceeds this amount, the front panel displays the following message:

"Maintenance Advised"

NOTE: The Maintenance Advised message could also appear when the Spittoon in the Service Station is full.

The Printer Information utility also conveys the usage information, and it is accessible by the user.

Once the maintenance advised message is displayed, the preventive maintenance kit must be used to replace the most worn parts of the printer. Use the Removal and Installation Chapter of this Service Manual as a guide to replace the necessary parts.
