    Re: C654E Cyan devloper suck

    When you say "add developer" , I'm assuming you are talking about aftermarket developer because I'm not aware of any dev from Kon/Min for that model? Are you using genuine K/M toner? If you are using aftermarket of either toner or dev that is your problem. I have never had good results with aftermarket, especially developer.
    I'm assuming you are a print shop, if so that is more reason to use genuine supplies to maintain consistent print quality to sell to customers. "pay more now, or a lot more later"
    I have print shops with that same machine. They run big jobs on them, mostly 12x18 thick stock. They use genuine IU's and toners. They chip/reset IU's at least once. Not sure how much more you would expect from these consumables? I have one C654 (reg paper) with 1.5 mil clicks and have the same color IU's, fuser etc. Have only changed black drum a few times.

    Are you resetting the image units?
    Make sure all the image process adjustments are on default.
    What is the TCR value under <state confirmation> <level history1>

    If it is the case that it cant get enough toner on time the TCR level will fall below 4% and an error will be given.


    Nope No error. Just a crap copy, lines. Add developer and good for a bit, but happens again.

    C654E Cyan devloper suck

    I have 3 c654. We run them pretty hard. With no problems. Recently we have been printing lots of postcards/double sided with large pictures on them. The Cyan IU are failing at half life. They are maintained and all sensors cleaned. I do manual toner add as much as I can. I still feel like the toner hoppers are running a low. Gradients being done every day. What else could be causing the developer suck? Can I make any adjustments for increasing toner add? Firmware has been updated. I am at a loss and about to spend 50k on 3 C7000. Help
Working...
