HP DesignJets 500, 510 and 800 Series Printers Service Manual
Cleaning the Drive Roller/Print Platen
NOTE If ink is spilled on the Drive Roller or the Print Platen, remove
the ink. Due to the ink's reflectance, ink on the Drive Roller or
the Print Platen can disrupt the Printer's edge-sensing function.
To remove any ink from the Drive Roller, perform the following
procedure:
WARNING Prevent water or other liquids from running onto electrical
components or circuits, or through openings in the module.
1 Perform the Turn Drive Roller Utility ⇒ Page 4-22.
2 Open the Top Cover and apply any common household cleaning
solution (water based only) to a soft, lint-free rag and apply it to the
Drive Roller surface while it is rotating. Thoroughly clean the Drive
Roller surface.
3 Press Enter when you have completed the cleaning procedure.
4 Allow the Drive Roller to dry before loading media in the Printer.
Scheduled Maintenance
In some segments of the printer market, the customer tends to print
more than the maximum number of prints that the throughput
allows, exceeding by far the limit of the design. When this happens
the customer runs into print quality problems and continuous Printer
failures.
The purpose of scheduled preventive maintenance is to avoid these
failures - ensuring a good performance during all the product life.
Level of Printer Usage
Normal printer use means 6,000,000 printing carriage cycles. Under
normal usage conditions, it will be approximately 5 years before the
printer needs maintenance. If the printer is used more than the
normal usage conditions, then it will need maintenance service
much more frequently.
One of the EEROM counters is assigned to counting the number of
carriage cycles as well as the usage cycles of other major
components. When the printer exceeds this amount, the front panel
