Section 7: Maintenance 51
4250/4225 Card Printer UserÕs Manual
4. Once the Printhead is completely dry, shut the cover. If a streak persists,
perform the steps in Part 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 Cover by pressing the 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.
3. Allow the Printhead to thoroughly dry before closing the cover.
4. Shut the cover. If a streak persists, contact your dealer for further assistance.
D. CLEANING THE PRINTER’S CASE
The printer has a durable casing that should retain its luster and appearance for
many years. Clean it only with a soft cloth slightly dampened with water or a mild
soap. Do not use excess water or cleaning solvents of any kind. Never spray the
cabinet with a cleaner. Rather, spray the cloth first, then wipe down the printer.
E. CLEANING THE INSIDE OF THE PRINTER
As you use your printer, dust and other foreign particles may accumulate inside the
printerÕs case. These particles are attracted to the underside of the ribbon by static
produced during printing and can cause voids on the printed image. Periodically,
use the following procedure to remove dust and other foreign particles:
1. Open the printerÕs Top Cover.
2. Remove the ribbon from the printer.
3. Use a Cleaning Pad from the Printer Cleaning Kit or a soft, lint-free cloth
slightly moistened with isopropyl alcohol to wipe out all visible areas inside
the printer. Remove any debris that may be inside. Be extremely careful not to
let any alcohol drip inside the printer!
4. Once the cleaned areas are completely dry and free of foreign debris, re-install
the ribbon, and close the cover.
