6.1 Overview

This section describes points and procedures for maintaining the printer in its optimum
condition.

6.1.1 Cleaning

The printer has no mechanical components which require regular cleaning. Therefore,
note that the points suggested below are only to check for dirt, and cleaning should be
performed upon necessity.
n

C A U T I O N
These chemicals can damage the printer components.
n
Be careful not to damage the components in attempt to clean
inside the printer.

a soft brush to wipe off the dust, or use a soft cloth moistened
with alcohol.)

stained with ink, use a cloth moistened with neutral detergent to wipe it off.

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.
o
Service limit of the protection counter A:
The service limit of the protection counter A
o
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.
n
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.
n
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.
