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 7156.

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 Printhead

Caution:  

Do not spray or try to clean the thermal printhead or the inside of the printer

with any kind of cleaner or soap as this may damage the thermal printhead and electronics.

If the thermal printhead appears dirty, wipe it with cotton swabs and rubbing alcohol.

If spotty or light printing problems persist after the thermal printhead has been cleaned,
see “Chapter 3: Solving Problems” for more information.

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 “Ordering Paper and Supplies” earlier in this manual for recommended paper.
