Cleaning the Printer Body
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!
DO NOT REMOVE SIDE COVERS! HIGH VOLTAGES PRESENT.
Clean the Printer regularly to remove accumulated paper dust and ink. Depending on the types of media
that are run, paper dust may accumulate inside the printer and on the transport.
1. If the printer is on; press the ON/OFF button to power-down the print engine. Wait about 45
seconds until the system shuts down (all control panel lights will go off). Turn off the Main Power
Switch and unplug the printer from the power receptacle.
WARNING! If this power-down process is not followed; ink color mixing and printhead nozzle
clogging may result.
2. Unplug the power cable from the printer.
3. Interior: Use a vacuum with a soft brush attachment to help loosen dust particles. Take care not to
damage the PC Boards or electrical wiring.
4. Exterior: Wipe clean with a lint-free cloth using any standard nonabrasive household cleaner that
does not contain plastic harming solvents.
CAUTION
NEVER SPRAY OR POUR CLEANERS DIRECTLY ON OR INTO THE PRINTER.
EXCESS LIQUID COULD HARM ELECTRONIC PARTS. DAMPEN A LINT-FREE
CLOTH WITH THE CLEANER AND APPLY IT TO THE PARTS TO BE CLEANED.
Cleaning the Feed Rollers and Forwarding Rollers
The rubber 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 lint-free cloth.
NOTE: Do NOT use solvents to clean the Rubber Rollers.
Cleaning the Encoder Wheel
Valid for early Print Engines (S/N SG09CZ1##### or lower); originally
install in Printer S/N 100027598 and lower.
NOTE: Current Print Engines have an enclosed Encoder Wheel, making this
procedure unnecessary.
If your Print Engine has an exposed Encoder Wheel (see picture at right); ink
overspray and splashes can accumulate on this wheel. This may cause an
interruption to printing and will issue a "DATA_PATH_UNDERRUN"
error in the Toolbox.
Periodically wipe ink deposits from this wheel to prevent or correct this issue.
Power the printer off and disconnect the power cord. Clean the wheel with distilled water on a damp, lint-
free cloth. Grasp the wheel lightly with the cloth while turning the feed shaft. Take care not to damage
the Encoder Wheel. If you are uncomfortable performing this task, or this issue reoccurs frequently;
please contact your support representative.
Tip: Access to this Encoder Wheel is improved if you open the print engine “clamshell”. See
“Troubleshooting” section for other possible causes for the “DATA_PATH_UNDERRUN” message.
