MAINTENANCE

6.1.2 Service Maintenance

If print irregularity (missing dot, white line, etc.) has occurred or the
printer indicates "Maintenance Error", take the following actions to clear
the error.

6.1.2.1 Head Cleaning

The printer has a built-in head cleaning function, which is activated
through the control panel operation. Run a head cleaning in the following
order:
1. Confirm that the printer is in stand-by state. (The power lamp is not
blinking.)
2. Hold down the cleaning button on the control panel for 3 seconds or
longer. (The power LED blinks during the cleaning.)

6.1.2.2 Maintenance Request Error Clear

Ink is used for cleaning as well as printing. During cleaning, the printer
drains some ink into the waste ink pads. The protection counter A in
EEPROM on the main board keeps track of the quantity of ink drained into
the waste ink pads. When the counter reaches the predefined service
limit, the printer assumes the waste ink pad is full of ink and requests ink
pad replacement by indicating a maintenance request error.

Timing for replacing the waste ink pad:
When the total amount of the waste ink reaches the predetermined
limit, a maintenance error occurs. In this condition, the printer does
not accept any input but from the power button.
!
Current counter value can be found on a status print sheet that
also shows the firmware version, selected code page, and nozzle
check pattern. During servicing, you are required to check the
counter value and if the counter is close to its limit, notify your
customer of the situation and recommend that the waste ink pad
be replaced (If the waste ink pad is not replaced at that time, there
is a possibility that a maintenance error will occur soon after the
