    It prints yellow across the lower 1/4 of the page only.

    All other colors seem to work fine.

    Its a fade - meaning the very bottom is full yellow, and then it fades out to nothing by about 1/4 up the page.

    My first guess would be ITB also, have seen it before.

    Update:

    I never did find a copy tech via the phone book (amazing how hard it is to locate a copy tech willing to service personal equipment, it seems only interested in ongoing service contracts)

    But I DID find a tech via this forum post - so thank you copytechnet! (and for the record, I paid the asking rate and am quite satisfied with the results)

    In the end it turned out to be a bad laser unit. Worst of all worlds, but swapped and fixed now and printing great.

    Now.... still wandering through the maze of 'scan to email' setup/troubleshooting with no luck, but thats another post.

    Thanks to everyone for all the insights!

    Before I swap the PCU - something else I should be trying first?
    Kind of looke like the polygon mirror faces for yellow are somewhat covered with dust or toner or something. I haven't seen this on Ricohs, but I have seen that enough times on HPs that I thought I'd suggest that.

    I would have checked the laser shutter was working correctly or removed it altogether, as these can cause fading when they do not open properly.
