Chapter 2: Setting Up and Using the Printer 7156 Setup and User’s Guide
September 199826
Cleaning the Printer
There is no customer maintenance required for the 7156 printer. However, you
may occasionally 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. The cabinet materials and finish are durable and are resistant to the following
items:
Cleaning solutions
Lubricants
Fuels
Cooking oils
Ultraviolet light
If the receipt paper bucket is dirty, wipe it with a clean, damp cloth.
Caution: Do not spray or try to clean the thermal printhead or the inside of the
printer with any kind of cleaner as this may damage the thermal printhead and the
electronics.
If the printhead appears dirty, wipe it with cotton swabs and rubbing alcohol. If
spotty or light printing problems persist after cleaning the thermal printhead,
contact your NCR authorized service organization.
Note: The thermal printhead 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 printhead with cotton swabs and
rubbing alcohol will not be of much benefit. See “Chapter 3: Ordering Paper and
Supplies” for recommended paper.
