    Test pattern priniting

    Hi all

    I'm pretty sure that on one of my courses (quite a while ago) the trainer told us that you could generate test patterns (not SP2-109) from different boards, as a way of trouble shooting image problems related to which ever particualr board is giving the issue. Is this right or have I completely dreamt this up?

    Cheers

    most of the machines let you use 2902-2 or 3. One of them uses the IPU and the other doesnt. IPU is the image processing unit of course.

    You never realize how cheap a professional is until after you let an amateur do it.

    Thanks Jomama46,

    I'll take a look at that. Does anyone else have any info on this? Can I generate a print from the BCU or the I/O board? Sounds stupid but I'm sure the trainer mentioned something about this.

    2902 Test Pattern

    2902 2 IPU Test Pattern Pattern 0 ~ 15
    Prints the test patterns for the IPU chip.
    This SP mode is useful for finding whether the BICU or the SBU is defective. If the
    printout is not OK, the BICU is defective.



    2902 3 Printing Test Pattern Pattern 0 ~38
    Prints the printer test patterns. Select the number of the test pattern that you want
    to print.
    This SP mode is useful for finding whether the LDDR or the BICU is defective. If
    the printout is not satisfactory, the LDDR is defective.

    Thanks teebee1234

    I think this is probably what I meant/remembered incorrectly.
