Receipt Printing is Light or Spotty
Problem What to Do Where to Go
Thermal print head may be dirty Open the receipt cover and clean the thermal
print head with cotton swabs and isopropyl
alcohol.
Caution: Do not use the alcohol to clean other
parts of the printer. Damage will occur.
Contact a service representative if this does
not resolve the problem.
See “Cleaning the Printer”
in chapter 2.
See “Contacting a Service
Representative” later in
this chapter.
Note: The thermal print head does not normally require cleaning if the
recommended paper grades are used. If non-recommended paper has been
used for an extended period of time, cleaning the print head with the
alcohol and cotton swabs will not be of much benefit. See “Ordering
Thermal Paper” in chapter 1 for recommended paper.

not resolve the problem. See “Printing on Forms or
