Inspection and Maintenance

Proper performance of the inspection and maintenance procedures described below allows this
unit to perform for the years of trouble-free operation for which it is designed.

Maintenance Procedures

The inspection procedures described here are divided between two types: daily inspection,
which can be performed by those who use the unit on a daily basis, and periodic inspection, to
be performed by individuals who have a more detailed technical knowledge of the unit.

Daily inspection

Inspection item

Setup

Check for proper installation of roll
paper and ribbon cassette. Is the
ribbon passing along the proper route?

Check the ribbon for damage.

Reconnect any cables that have
come loose.

Correctly install roll paper and the
ribbon cassette.

Replace the ribbon cassette, if
damaged.

Paper particles, paper
scraps, foreign matter

Open the roll paper cover and make
sure there are no large pieces of paper
or other foreign matter present.

Clean out any paper or foreign
matter.

Periodic inspection

Checkpoints

Standards

Remedies

Dust, paper particles, or
dirt on and in the printer

No dust, paper particles, or dirt should be
allowed to build up on or in the printer.

Clean the printer thoroughly with a
vacuum cleaner.

No small pieces of paper should be
left in the paper path.

Remove any pieces of paper from
the paper path.

Lubrication

See the “Lubricants” section.

Lubricate the points listed in the
“Lubrication Points” section.

Operation check

When each printer component is
checked, no abnormalities should be
found.

Check the printer following the
Troubleshooting flowcharts in
Chapter 4.

Shape of the springs

No spring should be bent or deformed. Replace any deformed springs.

Ribbon cassette

The ribbon cassette should be properly
installed in the printer.

See “Replacing the Ribbon Cassette”
in this chapter.

Check for proper connection of cables.
