6.2 Service Maintenance
When abnormal printing or a maintenance request error occurs, perform the maintenance service described
below.
6.2.1 Printhead Cleaning
If abnormal printing occurs, run a printhead cleaning sequence through the control panel. This may not have
an impact on printing performance, however, because the most suitable printhead cleaning sequence
(including flushing) is automatically performed during printing to keep the printer in its best condition.
1. Press the Pause button to put the printer into off-line status. (Pause LED goes off.)
2. Press the Shift and LF/FF buttons simultaneously for 2 seconds. The printer enters the black printhead
cleaning mode. (Press the Shift and Load/Eject buttons for the color printhead cleaning.) The printer
automatically exits the cleaning mode and returns to off-line status.
3. Press the Pause button after the cleaning is executed, and the printer goes into stand-by.
;
Do not perform cleaning unless the printouts are obviously abnormal.
;
Excessive cleaning may shorten carriage life.
6.2.2 Maintenance Request
This printer monitors the capacity of the ink drain pad by monitoring the amount of ink absorbed from the ink
cartridge. When the ink drain pads are close to capacity, a maintenance request error is indicated. While the
printer is in this status, it does not accept data from the host or any operation through the control panel.
Power on/off may also be ignored. In this case, reset the EEPROM. (Refer to Section 1.4.3 in Chapter 1.)
;
Replace the waste ink drain pads when resetting the EEPROM.
