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 “Solving Problems” later in this book.
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 “Recommended Suppliers” on
the next page for the recommended paper grades.
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 “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 “Solving Problems” later in this book to determine if the printhead
needs to be replaced.
