    Our problem is as follows:
    If you imagine an A3 sheet of paper after its been printed full colour, and then held up to view landscape, there are vertical lines which appear to be about 1 - 1.5mm wide, right across the whole of the sheet.

    After printing out separate colour copies, the problem is only visible on the Cyan sheet.

    A few months ago we were advised that the problem was with the Cyan drum.

    Its not often that we print solid colour over a wide area, so it hasn't been much of a problem. However, although we have replaced the Cyan drum twice now during the normal life cycle of the machine, the problem has remained.

    We now have a number of jobs to do which have large area's of solid to reproduce and the images have the striped effect all over them.

    Any suggestion of a remedy would be very much appreciated.

    Almost always it is the drum. If a brand new drum gives no improvement or change, it could be contamination of the laser glass or mirror.
    Also a possibility would be something on the roller under the transfer belt, although I feel this is less likely, it is not difficult to check.

    Hi xfactor printing for your quick response to my enquiry.

    As I said in the original post, the problem is only with the one colour - Cyan. Would a contaminated glass or mirror not effect all of the colours? The same for the transfer belt roller?

    I did wonder if it could be something to do with the drive mechanism for this drum?

    The strange thing is that resulting prints have these stripes that are so uniform you would think that they were part of a design.

    Sorry - I replied thinking the stripe was running the long way. There is one roller per color under the belt opposed to each drum. That is a long shot but easy to check/swap. The laser glass/mirror can also impact only one color.

    However if the stripe is running cross wise in the 11" direction of an 11x17 sheet then I was on the wrong idea totally.
    Then it could be a drive or gear issue and I've not seen this solved as the other direction is far more common on this model.

    Are they solid white stripes, very distinct, or lighter/darker areas that make it look striped?

    Good morning. The stripes look to be solid cyan, then a tint of cyan etc. and that is right along the sheet.
    As I suggested in the earlier post, its so uniform you would think it was a design.

    I've seen adverts on Ebay for drive assemblies, but didn't know if this problem could be caused by that, or what can go wrong with one.

    If the problem is caused by a drive unit, do you know where I can get the instructions as to how to replace it?

    Thank you for your help.
