Thermal Print Head

The 7167 Receipt Station uses a thermal print head for printing receipts, and is extremely
fast and quiet. Since it uses heat to print directly on paper, there is no cassette or ribbon to
change, eliminating soiled fingers and paper dust.
There is no regularly scheduled maintenance for the print head and it does not need to be
regularly cleaned. However, if it does appear dirty, wipe it with cotton swabs and rubbing
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 is 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 Receipt Paper" on the next page for the recommended paper.
The print head is designed for a very long life, but it may be replaced if needed. Only a
trained service representative may replace the print head. See "Chapter 3: Solving
Problems" to determine if the print head needs to be replaced.

Impact Print Head

The bi-directional, impact print head is designed for a very long life, but it may be
replaced if needed. Only a trained service technician may replace the impact print head.
See "Chapter 3: Solving Problems" to determine if the print head needs to be replaced.
