4 Maintenance Guidelines
Cleaning the Printer
Clean the outside of the cabinet as needed to remove dust and finger marks. Use any household
cleaner made for plastics. Test it first on a small unseen area. Clean the printer paper bucket with a
clean, damp cloth.
The cabinet materials and finish are durable and resistant to the following items:
● Cleaning solutions
● Cooking oils
● Lubricants
● Ultraviolet light
● Fuels
Cleaning the Thermal Printhead
CAUTION: Do not clean the inside of the printer with any cleaner. Do not allow cleaning spray to
come in contact with the thermal printhead. Damage to the internal electronics or thermal printhead
could occur.
NOTE: The thermal printhead does not normally require cleaning when recommended paper grades
are used. If non-recommended paper is used over an extended period, attempting to clean the
printhead will have little effect on the print quality.
1. Turn off the printer and POS computer.
2. Unplug the printer from the POS computer and the cash drawer, if connected.
3. Wipe the printhead with a cotton swab moistened with rubbing alcohol.
CAUTION: Do not use rubbing alcohol to clean any internal parts of the printer other than the
printhead. Damage will occur.
If spotty or light printing problems persist after cleaning the thermal printhead, the entire thermal
mechanism may need to be replaced.
CAUTION: Using non-recommended paper over an extended period of time can result in printhead
failure. Refer to Technical Specifications on page 23 for paper specifications.
