7156 Owner's Guide

General Features

Note: The 7156 does not use a paper journal. The journal is kept electronically by the host
computer.

Options

Thermal Printhead

The 7156 uses a thermal printhead (on the receipt station) for printing receipts, and it 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 printhead 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 cleaning the printhead, contact a
service representative. See "Contacting a Service Representative" in "Chapter 3: Solving
Problems" later in this book.
Note: The thermal printhead 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 printhead 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 printhead is designed for a very long life, but it may be replaced if needed. Only a
trained service representative may replace the printhead. See "Chapter 3: Solving
Problems" to determine if the printhead needs to be replaced.

Impact Printhead

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