3. Cleaning ink cartridge guide roller/guide plate (when replacing ink ribbon, perform the
following.)
There may be some dirt such as powdery white dust stuck on the ink cartridge guide roller or
guide plate as shown in the area colored red below.
If you find any dirt on the guide plate when replacing an ink ribbon, wipe it from the guide plate
using our cleaning plate or some other commercial wiping paper moistened with our specified
cleaning agent.
* Once a cleaning plate is used for the guide roller/guide
plate, do not use the same plate for cleaning the
thermal head. Applying the same plate both to guide
roller/guide plate and thermal head results in printer
failure or poor print quality.
* Notice the guide roller/guide plate to be cleaned is the
one installed in the take-up side of the ink ribbon.
4. Cleaning the cooling fan filter (every half year)
Remove a large screw that holds the grid in place,
remove the grid, take out the filter from the grid,
wash the filer with water, let it fully dry, and then
replace the grid and filter.
Cleaning
the tray
Use an appropriate brush or toothbrush to sweep the
tray clean.
Before you attempt to clean the filter, it is imperative to shut down the P-55, wait for the cooling
fan to stop and unplug the power cord.
(To drop the temperature inside the unit, the fan continues to revolve for about 10 to 20 minutes after
the power is shut off to the unit.)
Areas indicated by the hazardous heat warning labels are very hot while the power is turned on
or just after the power is turned off.
5. Periodic Checks and Maintenance by Service Personnel
It is recommended that the inside of the unit be checked and consumable parts be replaced on a
regular basis so that print quality consistency can be maintained. For information about maintenance
or repairs, contact our customer representative.
Ink ribbon dust may
