    Re: Damaged drums in transport?

    should have rapped then in dark drum cloth. paper is not a good light blocker esp in a car with bright light. but over due drums will have way different voltages.

    If it were light shock you would be missing image of that specific color. Interestingly, sometimes light shock can be recovered from with a hundred or so image cycles.

    I've seen temperature changes cause smears and streaks, from condensation on the drum(s) or mirrors. Most common after a delivery machine sits in the cold truck overnight, then gets dragged into a warm room and immediate fired up. The rule on such things is you should allow an equal amount of time for the machine to acclimate.

    For transportation I have a black plastic bag (once held a drum unit). It lets very little light in.

    I seem to recall removing a new Selerium Tellurium drum in the original packaging from a 110F car one very hot summer, and got completely blank images .. for about 30 minutes. It did come back gradually.

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    Did you put new chips on them when you installed them?

    If not, i always put new chips if changing drums from one machine to another as they would have completely different charges.

    Sometimes you can get away with it, but generally you'd be better of spending 4 on a new chip.

    No, i did not change chips.
    There is no logic to me to put new chips to old weared drums, that really could make mess if machine thinks it have new drum.
    In this specific situation drums on both machines are roughly same age and life so that should not be the problem.
    In the past i done many times drum K instead drum CMY (c220,c224) ) ,never replace chips and never have problem, just put back old CMY chips on drum K.
