Cleaning the Printer
Cleaning the Cabinet
The external cabinet materials and finish are durable and resistant to these items:
• Cleaning solutions
• Lubricants
• Fuels
• Cooking oils
• Ultraviolet light
There is no scheduled maintenance required for the 7197.
Clean the cabinet as needed to remove dust and finger marks. Use any household
cleaner designed for plastics, but test it first on a small unseen area. If the receipt
bucket is dirty, wipe it with a clean, damp cloth.
Cleaning the Thermal Print Head
Caution: Do not spray or try to clean the thermal print head or the inside of the
printer with any kind of cleaner as this may damage the thermal print head and
electronics.
If the thermal print head appears dirty, wipe it with cotton swabs and isoprophl
alcohol.
If spotty or light printing problems persist after the thermal print head has been
cleaned, see “Chapter 3: Solving Problems” for more information.
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 cotton swabs and
rubbing alcohol will not be of much benefit. See “Ordering Paper and Supplies”
earlier in this manual for recommended paper.
