6.1 Overview

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

6.1.1 Cleaning

This printer has no mechanical components which require regular
cleaning. Therefore, note that the points suggested below are only to
check for dirt, and perform appropriate cleaning if necessary.

Never use chemical solvents, such as thinner, to
C A U T I O N
clean the printer. These chemicals can damage the
components of the printer.

Be careful not to damage the components when you
attempt to clean the inside the printer.

Do not scratch surface of "ROLLER, ASSEMBLY, PF".
(Use soft brush to wipe off any dusts, or use a soft
cloth moistened with alcohol.)


Housing:
Use a clean soft cloth moistened with water and wipe off any dirt. If
the housing is stained with ink, use a cloth moistened with neutral
detergent to wipe it off.


Inside the printer:
Use a vacuum cleaner to remove any paper dust.

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.


Head Cleaning
The printer has a built-in head cleaning function and is activated
through the control panel operation.
1. Confirm that the printer is in stand-by state (the POWER indicator
is not blinking), and hold down the cleaning button on the control
panel for more than 3 seconds.
2. The printer enters the built-in cleaning sequence. (During the
sequence, the POWER indicator is blinking.)


Maintenance Error Clear
Ink is used for the operations such as cleaning as well as printing.
Therefore, the printer wastes certain amount of ink and counts the
amount of waste ink and drains it into the waste ink pad. Once the
amount of waste ink reaches the predefined limit, the printer
indicates "MAINTENANCE ERROR" and the waste ink pad should
be replaced.
(See Chapter 1 / Page 1-25 for details.)
