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 occurs, you can enter the printhead cleaning mode through the control panel
operation. Also, to keep the printer in the best condition, the printer automatically selects the cleaning level
(including flushing) and carries it out even while printing. Follow the steps below to enter the printhead
cleaning mode.
1. Press "Pause" button to put the printer into the off-line status. (Pause LED goes off.)
2. Clean the black or color printhead by pressing the corresponding "Cleaning" button. (The printer goes
back to the off-line status when the cleaning completes.)
3. Press "Pause" to put the printer back to the stand-by status.


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


Excessive cleaning may shorten the cartridge life.

6.2.2 Maintenance Request

This printer counts the amount of ink absorbed from the ink cartridges to monitor the capacity of the ink
drain pads. When the ink drain pads are close to capacity, the maintenance request error is indicated.
While the printer is in this status, the printer stops accepting printing data from the host and every
operative signal except for the power on/off signals sent from the control panel. In this case, perform
EEPROM reset operation. (Refer to Chapter 1.)


Be sure to replace the waste ink drain pads when performing EEPROM reset. (Refer to Chapter 3)
