MAINTENANCE
Maintenance request error (Maintenance call error)
Ink is used for the Print Head cleaning operation as well as the printing operation.
When the ink is used for the Print Head cleaning operation, the ink is drained to
the Waste ink pads and the amount of the waste ink is stored as the waste ink
counter into the EEPROM on the Main Board. Due to this, when the waste ink
counter has reached the limit of the absorbing capability of the Waste ink pads, the
Maintenance call error is indicated on Status monitor 3 as following figure.
Figure 6-3. Maintenance error indication in STM3
In this case, replace to new Waste ink pads and clear the waste ink counter stored into
the EEPROM. The waste ink counter can be reset only from the Adjustment program
because this printer dose not have the waste ink counter reset function by the control
panel SW. As for the procedure, refer to Chapter 5 Adjustment.
In your repair activity, check the waste ink counter along with the firmware version,
Main Board checker program version and nozzle check pattern on the nozzle check
pattern printing. If the waste ink counter is closed to its limit, recommend that the
Waste ink pads will be replaced with new one. This is because the "Maintenance
request error" will may occur after returning the repaired product to the customer.
