    Trendsetter - irregular banding, stripes on plates

    Have a problem with Trendsetter 800 II Quantum TH 1.7 (TSMCE 2005).
    Irregular banding occurs on plates in mainscan direction. Stripes width is about 2mm. In the log-files there is messages:
    <MCE> *** Unsolicited Message 44964 Fatal
    <MCE> [THC1:focus error detected at 414.159 mm from HOME tab while imaging, check plate for artifacts]

    After processing stripes disappears sometimes, mostly not.
    I understand that problem lies in the autofocus system, but with autofocus switched off isn't possible to make good plates.
    Kodak service in Ukraine can't help with problem, just propose to change TH. It's too expensive for us.
    Can you help with documentation about autofocus system and procedure of install/deinstall TH 1.7 on Trendsetter 800 II Quantum.
    Maybe it's impossible to solve this problem? Just head replacement or maybe CTP replacement will be better option?
    Thanks in advance!

    Service Specialist needed to ckeck you SR parameter value and SD value too

    Hello

    You need your plate SR and SD parameter values be checked. those parameters have to be checked inside thermal head parameters for the created and used media

    they're very important to get good plates to be imaged by the laser.

    Yes, I understand, but I think it/s ok:
    set hdm sr - sr = 0.12
    set hdm sd - sd = 0
