5-2 Maintenance Schedule
Maintenance Schedule
The following types of maintenance are recommended:
◆ Daily and “as needed” maintenance
◆ Printing interval warning — the printer maintains a periodic
maintenance clock that tracks the total amount of time the
printer has spent printing. After the periodic maintenance
interval has been reached, the AT TN key will appear on the
control panel, and the user will be advised to perform the
periodic maintenance items described in this chapter. When
you dismiss the warning message, the maintenance clock is
reset. The printer does not verify that the periodic mainte-
nance is actually performed.
◆ 2000 ml printhead purge
See the following table and the remainder of this chapter for
details and instructions.
