    HP ColorJet 8550 DN - How to Reset Drum Count?

    I've got a HP 8550 color laser printer and the drum has "run out". The copies are printing just fine and I've only printed about 7000 pages. The expected life is much more... I really don't feel that replacement is necesssary at this time!!

    Anyone know how to reset the "count" so that I may continue to use the same drum?? The printer will not print until I replace the drum!!!

    The instructions for the printer do not cover this procedure and they state to follow the instructions in the drum replacement kit...figures!

    Please Help!!

    Do you have some friends who uses the same printer as yours? you can change drums and back again you old drum after the printer detected a new drum from your friend

    You can try here if you can disable the counter.

    Nope. The printer is just a bit on the expensive side, so there are not too many around the office.

    Anyone know if there is a "fuse" in the replacement drum kit that triggers the counter to reset?

    can you disable "bi-directional communication" if it uses this feature???

    Actually, its not the computer end that is refusing the print. Its the printer!

    It has a 2-line, 20-character panel that displays messages. Currently: Replace Image Drum, Life Expended.

    (and will not print ANYTHING until its replaced) Rude, huh?

    The "last" page it printed is fine, great quality. There is nothing wrong with the drum (I pulled it out and checked it over). It just states its life is out and will not let me print!!

    Cannot find any sensors that would tell the printer that a different drum (or the same) is installed. How does it know I replaced it with the same drum?

    I believe the "bi-directional" communication is making use of the counter feature.

    Try searching "HPcnfg*" if it has the option to diasable some features of your printer.

    goodluck
