6.2 Service Maintenance

When an abnormal printing or the maintenance request error occurs, perform maintenance service
described below.

6.2.1 Head Cleaning

In case abnormal printing result is identified, perform head cleaning sequence through the control panel
operation. The head cleaning sequence is, however, automatically performed during printing operation to
keep the printer in its best condition. The printer selects the most suitable cleaning sequence (including
Flushing operation) referring to the printer 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, and the printer enters the black
cleaning mode. (Press Shift and Load/Eject buttons for the color head 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 the stand-by status.


Do not perform cleaning unless the printing result is obviously abnormal.


Excessive cleaning may shorten the carriage life.

6.2.2 Maintenance Request

This printer monitors the capacity of ink drain pad for absorbing ink by counting amount of ink absorbed
from the ink cartridge. When the ink drain pads are close to capacity, the maintenance request error is
indicated. While the printer is in this status, it does not accept data from the host and any operation
through the control panel except for power on/off is also ignored. In this case, perform EEPROM reset
operation. (Refer to Section 1.4.3 in Chapter 1.)


Be sure to replace the waste ink drain pads when performing EEPROM reset.
