9-4 Preventive Maintenance
HP DesignJet 430, 450C and 455CA Printers
Cleaning the Printer
To maintain the Printer in good operating condition, keep it free of dust
accumulation, ink, and other contamination. Cleaning intervals are
determined by the Printer environment and by the types of Printer supplies
used.
Disconnect the Printer from the power source prior
to performing any cleaning. DO NOT allow liquid to
run on to electrical components or circuits, or
through openings in the enclosure, as this can
create a shock hazard leading to death or injury.
WARNING
General Cleaning
Proper general cleaning should include the following:
1 Blow away dust accumulation with compressed air if available.
2 Clean the outer surface of the Printer with a damp sponge or cloth. Use a
mild soap and water solution if necessary. Do not use abrasive cleaners.
3 Wipe the Printer dry with a soft lintĆfree cloth.
Cleaning the Drive Roller
Due to the ink's reflectance, ink spilled on the roller can disrupt the Printer's
edgeĆsensing function. To remove any ink from the roller, perform the
following procedure:
1 Connect the Printer to the ac power source.
2 Switch the Printer ON, and wait for it to finish initialization.
3 Open the top cover.
4 Keep the cover switch pressed while pressing
Form Feed repeatedly until the
stained area of the drive roller is positioned at the top where it can be
cleaned.
5 Turn the Printer OFF, and disconnect it from the ac power source.
6 Apply IPA (alcohol) to a soft, lintĆfree rag.
7 Use the rag to clean the roller surface.
8 Allow the drive roller to dry.
9 If other areas of the roller have been stained by ink, repeat the above
steps.
10 Reconnect the Printer to the ac source, turn the Printer on, and load
paper to test that no ink reflections disrupt operation of media loading.
