21.7 Cleaning the Recorder Printhead
If the recorder has been used for a long time, deposits of paper debris may collect on the
printhead compromising the print quality and shortening the lifetime of the roller. Follow this
procedure to clean the printhead:
1. Take measures against the static electricity such as Disposable Wrist Strap for the work.
2. Open the recorder door and take out the paper.
3. Gently wipe around the printhead using cotton swabs dampened with alcohol.
4. After the alcohol has completely been dried, reload the paper and close the recorder
door.
CAUTION
z Do not use anything that may destroy the thermal element.
z Do not add unnecessary force to the thermal head.
