Cleaning
The HJ500P
WARNING
THE PRINTER IS A PRECISION MACHINE THAT SHOULD BE CLEANED REGULARLY TO INSURE
MANY YEARS OF SERVICE. BEFORE PERFORMING ANY MAINTENANCE DISCONNECT THE
MACHINE FROM ITS POWER SOURCE!
The Printer must be cleaned regularly of accumulated paper dust and ink. Depending on the types of media that
are run, paper dust may accumulate within the printer and on the transport. To properly clean the printer, unplug
it from the power receptacle and remove the covers.
The internal areas are best cleaned with a vacuum that has a soft brush attachment to help loosen the dust
particles. Take care not to damage the PC Boards or electrical wiring.
The exterior of the machine may be cleaned with any standard household cleaner which is non-abrasive and
does not contain plastic harming solvents.
CAUTION
NEVER SPRAY OR POUR CLEANERS DIRECTLY ON OR INTO THE PRINTER. EXCESS
LIQUID COULD HARM ELECTRONIC PARTS. ALWAYS DAMPEN A RAG WITH THE
CLEANER AND APPLY IT TO THE PARTS TO BE CLEANED.
Feed Rollers and Forwarding Rollers
The feed and forwarding rollers can become glazed with paper lint and ink from the media. They should be
regularly cleaned with a mild abrasive household cleaner on a damp cloth.
Avoid using solvents on the rubber rollers.
Cleaning the Media Sensor
Periodically check the media sensor located in the print
carriage area of the printer section. The sensor should be
clean and free of accumulated paper dust. Use a vacuum
with a soft brush attachment or dry compressed air to remove
the dust.
