Maintenance Overview 450
6.1.1 Product Life Information
Work Life Preservation Items
This printer does not have periodic replacement parts that require periodic
replacement before reaching the end of the product work life.
However, if this printer continues to be used after the product work life,
service call errors will be displayed before part failures occur and
messages will be presented to advise part replacement. (This excludes the
Maintenance Tank and Cutter consumable parts.)
Corresponding parts are shown below.
Work Life Information
Work life information can be checked from the "Printer Status Menu" of the
panel settings. The display will show the remaining percentage in relation
to the specified control value (displays "F*****E"). These values saved in
the counters can be cleared using "Maintenance Mode 2".
6.1.2 Important Maintenance Items During Service
Operations
Check the following items during printer maintenance/service and perform any
necessary operations.
Cleaning on the Platen and Subpaten
Brush away dust and paper dust, and wipe the whole surface with a OA
cleaner. If the paper absorption holes are clogged, push the paper dust
into the inside of the printer using a precision driver or a similar tool.
C A U T I O N
The cutter uses a very hard blade that is unusually
brittle, so do not allow it to be damaged by bumping into
objects such as metal printer parts.
If the printer that has already been installed needs to be
packed and transported again, first make certain that the
print head has been capped properly with the power to
the printer turned off. Then remove all the ink cartridges
and install all the packing materials as referred to in the
Start-Up Guide or Assembly and Setup Guide supplied
with the printer.

Do not clear counters that do not correspond to a part

value for the "MAINT TANK" counter is especially prohibited,
because it can affect printer operation and lead to ink
leakage.
