    DocuColor 242 - needs some maintenance - what to replace

    I have a DC242 with around 800k copies that has been great for the past 12 months. However I am seeing some degradation of quality and I think it is time to spend a little money on maintenance. My questions are what to replace to improve it.

    1. Faint lines on solids and gradients especially Cyan

    Solid colors are no longer completely clean and appear to have very faint lines running vertically down the sheet - more obvious on Cyan (graduated skies for example).

    2. Large X which looks like a scratch

    Most noticeable on coated papers, this looks like a large X that someone has scribbled on the paper but it appears across the whole sheet approx 3 inches but offset and repeating.

    3. A black defect about 1/4 in diameter appears on about every 4th sheet (A4) or 2nd or 3rd sheet (A3) always in the same horizontal position but varies vertically on the page - I suspect a mark on the IBT belt but cannot see it visually.

    I've swapped drums around with new ones and it hasn't improved any of the symptoms. The toners are all brand new. The fuser is fairly old - I tried another old one but didn't see any differences but I probably do need a new fuser.

    Any thoughts on what to spend the money on to improve things?

    At 800k it's a good ideea to do a deep clean to the machine,to change developer material from every developer unit assy , all machine filters and ibt cleanner module. Assuming the drums modules are new you can check the prin/copy quality and next step for parts change if needed is ibt belt and 2nd BTR roll.

    Get into service mode then go to Print Report / BIlling meters > CE > HFSI report
    It will print out a 2 page list with a load of numbers on it this is the High Frequency Service Interval items.
    Those with current readings higher than the life span reading will want replacing.

    From experience >

    Developer housings & developer
    IBT belt
    IBT cleaner
    CC Filter
    Ozone Filter
    Toner Filter
    2nd BTR
    1st BTR (C,M,Y & K)
    Tray Rollers (especially the Tray 5 set of rollers)

    954-824
    954-825
    954-826
    954-827
    954-828

    824, 825,826 & 827 = 1st BTR rollers one for each colour
    828 = IBT Cleaner Assembly
    829 = 2nd BTR Assembly
    834 = CC Filter
    835 = Ozone Filter
    836 = Fuser Filter (told to disregard & ignore this one)

    1st BTR change if you notice fading especially in tints so an orange looks slightly more magenta or yellow in a certain place
    IBT cleaner will leave dirty brown / dark streaks down a page more often down a side rather than all over the page
    2nd BTR can cause either marking on the rear of sheets or a fading across the page
    Filters will cause different wierd and wonderful IQ issues considering they are cheap in comparison change them every time it wants them.

    Changing everything now will mean that the IQ issues listed above you will miss out on .... and that's half the fun

    Re: DocuColor 242 - needs some maintenance - what to replace

    Thanks everyone for your help. I have found a set of 1st BTR rollers (new Xerox) which I think are the first things to replace - are there any instructions anywhere on the procedure to follow?

    I'm also waiting for an IBT Cleaner Assembly to arrive - again, any instructions on replacing please?

    I am trying to track down the 2 ozone filters - wow they are expensive for filters (don't they make a K&N for it hahaha) - what symptoms do you get from an overused ozone filter?

    I also replaced a color drum which was one of the chinese manufactured rebuilt drums - made a noticable difference to print quality and it's only done about 5000 copies - I think I will stick with genuine Xerox parts in the future!

    Thanks again for your help

    Steve
