E.2 Print Head Cleaning

CAUTION:

The print head is very hot right after printing and is very dangerous. Be sure to allow the

print head to cool down (after printing) before cleaning it. Also, be sure to turn off the

printer power before cleaning the print head.

Paper dust on the heating elements may lower the print quality. In this case, clean the print head

as follows.

1. Turn off the power.

2. Open the roll paper cover.

3. Clean the thermal elements of the print head using a cotton swab moistened with alcohol

solvent (ethanol, methanol, IPA).

CAUTION:

Do not touch the print head thermal elements with your bare hands. Doing so may have

a bad effect on the head thermal elements due to the adhesion of dirt.

Be careful not to scratch the print head when cleaning it.

4. Inatall roll paper and close the roll paper cover.

For the method of inserting the roll paper, refer to "Paper Loading Method" on page 2-41.

5. Close the roll paper cover.
