HP Designjet T7200 - Preventive Maintenance Kits

Preventive Maintenance Kits
Normal printer use means 6,000,000 Carriage Cycles (which corresponds to approximately 100,000 A0 prints
on average). Under normal usage conditions, it will be approximately 5 years before the printer needs
maintenance. If the printer is used more heavily than normal, then it will need maintenance service much
more frequently.
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:
“Maintenance #1 required”
The following message is triggered depending on the total quantity of ink spitted in each Spittoon.
“Maintenance #2 required”
Depending on the total turns forward of the drive motor, the following message is shown:.
“Maintenance #3 required”
Once one of the maintenance advised messages is displayed, the preventive maintenance kit must be used to
replace the most worn parts of the printer. See
Printer part removal and installation on page 205.
