606 Chapter 9 Preventive Maintenance
Preventive Maintenance
One of the EEROM counters is assigned to counting the number of carriage cycles. When certain
components of the Printer exceed this amount, the front panel displays the following message:
“Service Maintenance #1 required”
The following message is triggered depending on the number of Service Station cycles.
“Service Maintenance #2 required”
The following message is triggered depending on the total quantity of ink that has gone into the Ink Funnel.
“Service Maintenance #3 required”
Once one of the maintenance advised messages is displayed, the appropriate service 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.
