NCR 7156 manual Cleaning the Printer

Chapter 2: Setting Up and Using the Printer 7156 Setup and User’s Guide

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.
