MAINTENANCE Overview 142
6.1.2.4 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.
†
Service limit of the protection counter A:
The service limit of the protection counter A
=
35400
†
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
printer is returned to the customer). Once you have the
confirmation of the customer, replace the waste ink pad and reset
the counter.
„
The counter limit is generally 25000 pages and 10000 pages for
black and color, respectively. In normal use, the counter reaches
the limit in 5 years.
†
Replacement procedure:
Refer to Section 4.2.5.
†
Operation after replacement:
