    That copier was discontinued so long ago that Toshiba Tec does not provide the service manuals anymore.

    Re: toshiba 166

    Are all the optics clean? Is the white plate clean and white? There must be some sort of calibration for the CIS... ?

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    eStudio 163/203 CIS Unit PN - 6LE64010000 SNSR-CISM-280 have a different part number/name description than eStudio 166/206 6LH25860000 ASY-CIS-284 so it won't work, different machine series

    Main Board e166 PN - 6LH28100000 not the same as Main Board e163 PN-6LE63158000 = they don't match

    C26: Peak detection error

    Does the exposure lamp light? (Perform the output check in the test mode: 04-267)

    ��
    YES �� Replace the CIS unit.

    NO

    1) Check if the connector of the CIS unit are disconnected.

    2) Check the MAIN board if the connector (CN6) is disconnected and the harness is short

    circuited or open circuited.

    3) Check if the conductor pattern on the MAIN board is short circuited or open circuited.

    4) Replace the MAIN board.

    5) Replace the CIS unit.

    You need a e166/203 CIS UNIT to test or e166 Main Board only in your faulty e166.

    Check what Blackcat said about the white reference plate under scanner glass, must be clean.

    Totally agree, although my glorious days with Toshiba are gone. Still worth it to check and clean optics and especially white plate reference strip BC mentioned in case of C26 error.

    wish the OP would respond to some of these questions.

    WHY did he start replacing PARTS before thoroughly cleaning EVERYTHING?

    are the copies of printed paper? ( defect on org .. not noticed but when copied defect more prevalent)

    my bet is not properly cleaned optics.

    were these NEW/known good parts?
