Thermal Print Head
CAUTION:
This job may be performed only after turning off the printer and waiting for
approximately 10 minutes. The thermal print head assembly may be hot, and
otherwise, you might get burned.
When performing this job, take anti-static measures, such as wearing a grounded
wrist band. Failure to do so may result in thermal print head failure.
Do not touch the print head (portion that appears like a black line, and the
adjacent areas) in the thermal print head assembly. Touching this area may result in
thermal print head failure.
When the thermal print head assembly is contaminated or has a deposit of foreign
particles, wipe it off with a cotton swab moistened with alcohol.
1. While holding the two head holder springs so they do not fly out, pull out the spring holder
plate.
CAUTION:
Be sure to hold the two head holder springs while removing spring holder plate.
Otherwise, head holder springs may suddenly fly out, creating the danger of eye
injury.
