B. Standard
Printhead
Cleaning
This procedure should be performed if you notice a
streak on the card where color was not transferred.
This procedure should also be performed during
every ribbon change or after every 250 prints in
order to maintain consistent print quality. The
printhead is located near the center of the opened
top cover assembly.
1. Open the printerÕs top-right cover by pressing
its Cover Release Button.
2. If you observe dust and/or other particles
laying on the top surface of the ribbon, manually
roll it up into the take-up roll. Occasionally, dust
may settle on the top surface of the ribbon and
cause print quality problems.
3. Use a Printhead Cleaning Pen from the Printer
Cleaning Kit or a soft, lint-free cloth slightly
moistened with isopropyl alcohol to wipe dust and
other accumulated particles off the surface of the
printhead. If using a cloth, be extremely careful not
to use too much alcohol. It must not be allowed to
drip into the printer!
4. Once the printhead is completely dry, shut the
cover. If a streak persists, perform the steps in
section C.
C. Expanded
Printhead
Cleaning
Perform if you have a streak on the printed output
that canÕt be solved by the Standard Printhead
Cleaning procedure. To maintain your printerÕs
high quality of printing, this procedure should also
be performed approximately every 2,500 prints as
part of the printerÕs general maintenance program.
1. Open the printerÕs top-right cover by pressing
its Cover Release Button.
2. Use a soft, lint-free cloth slightly moistened
with acetone to wipe off the surface of the
printhead. Be extremely careful not to use too much
acetone. It must not be allowed to drip into the
printer!
CAUTION!
ACETONE IS A VERY POWERFUL SOLVENT. DO
NOT APPLY ACETONE TO ANY OTHER AREA OF
THE PRINTER, SINCE IT WILL DESTROY THE
FINISH OF PAINT, RUBBER, AND PLASTIC.
