    HP M775z lines from transfer belt

    We have a customer that has 2 M775z's. Both of the machines will have the same problem. After about 48k pages they start to get lines form the transfer belt unit. You can clean the belt and cleaning unit and it will go away but eventually the lines score deep enough into the belt that it has to be replaced. We are using OEM toner. Also it seems like the toner just sits against the blade and the belt and has a difficult time getting into the transport area. This continues to happen even after replacing the transfer belt unit. Anyone seen this before? Seems odd that it happens on both machines.

    thanks
    Dennis

    sorry, bit it is good to hear that we are not the only ones experiencing this problem. I'm not sure there is a fix. Seems like a bad design the way the toner piles up against the blade and belt.

    I've been wanting to tear one of them apart, but, not. Mainly because I don't want toner all over the place.

    My m750 (same belt) just got lines at 15k..they're using generic toner. I don't have any control over that but the belt was OEM. But I made sure to check the waste system wasn't backed up. It's actually very simple design and was functioning.

    In this situation, toner manufacture doesn't matter. Have seen these belts get backed up when using nothing BUT HP toner.

    Re: HP M775z lines from transfer belt

    I have same problems with 2 machines M775 - not so many pages printed (15.000 or 40.000) and the transfer belt has lines on it. I must replaced them. With genuine toners.
    I think there is problem with cleaning mechanism.
    The manifacturing is at poor quality?

    Probably poor cleaning blade material.

    I'll say me too, customer with 2 551's, every few months I have to go out and clean the transfer belts, then all good for a few months.
