HP Designjet 250c Service Manual - Page 41

Ink Spilling The service configuration plot gives an estimation of the amount of ink in the plotter's spittoon. (Details ' page 8Ć49 or 8Ć50.) To prevent ink spilling, replace both the spittoon and the inkĆseparator when the spittoon is almost full. About 880 primes are needed to fill up the inkĆseparator. Note that if you clear the EEROM or replace the electronics module, the factory spittoon value is reset to 0% used. Keep in mind that the value printed on the service configuration plot may greatly underestimate the amount of ink in the spittoon. Future PCĆbased plotter diagnostics will enable you to download information from the old EEROM and upload it to the new EEROM. Belt Swelling To prevent new belts from swelling incorrectly, keep them in their bags with dissicant until you need to install them. Cleaning the RollĆfeed Assembly Always clean the rubber diverter of the rollĆfeed assembly with a dry cloth. Never clean it with water or alcohol based substances.
