Maintenance of the printer may be carried out as required. However, some 

environments may require that maintenance must be done more frequently 

(e.g. in dusty conditions).

Print Head Maintenance

Use a cotton swab to wipe the print head.

Roller Maintenance

Use a piece of cellophane tape or a lint-free cloth to remove dirt from the 

roller. After cleaning the roller, make sure that no lint or other material remains 

on the roller.

Paper Outlet Maintenance

If the paper outlet becomes dirty, press and hold the   (Power) button to turn 

the printer off and clean the paper outlet with a cloth slightly moistened with 

isopropyl alcohol.

You can use the 

 (Feed) button to print a report that lists the following 

printer settings:

Program version

Printer usage history

Missing dot test pattern

Printer setting information

List of transferred data

Network setting information

1.

3.

Press and hold the 

 (Feed) button until the POWER indicator starts
