    Image position/placement problem on B402SC

    One of my customers has a B402SC with a little over 1M clicks. Runs fine but the image shifts ever so slightly (+/- 3mm) toward the trailing edge every 2-3 pages. For normal printing that would be unnoticeable but on certain charts (that she prints in landscape and with narrow margins) it is obvious because part of the last column is getting cut off. Never a jam, maintenance is current, cleaned PS unit rollers, looking for some help to figure out a track to follow to figure this out. PS unit replacement? PS clutch? It seems like a timing issue more than a process issue. Thanks in advance!

    First, I would determine of the shift occurs from all trays. If it does, PS clutch and and registration roller would be suspect.
    If it only does it from a certain tray, feed clutch would be suspect.

    If its a print that close, have her print the chart at 97% zoom..easy way out.


    Failing to plan is planning to fail!!!

    lol I tried having her scale it down but it turns out she was already doing that! Trouble is that any smaller some of the text is almost too small to read. Thereís way too much on these tables that she needs to print. Thanks for the advice I will try to isolate it to tray or PS unit. Since jams havenít been the issue and no clutch noises I wasnít sure if clutches can be late or if they work until they donít. And yes 1m is a lot but these little beasts run pretty well with regular maintenance and our company is good about keeping on schedule for preventing problems.

    Replace the paper feed drive unit.

    Part #CFRM-1409FC32

    This includes all clutches in the transport, PS, and feed from tray #1.

    I have done several of these and it always fixes the issue you are discribing.

    It takes less than 10 minutes to replace.

    Problem solved with new tray 1 paper feed unit. Having her switch the print job to tray 2 was the simple thing i didn't think of! thanks for the suggestions!!
