    Transfer belt issue. Clean the ID sensor located to the left of the transfer belt. If that fails, take the transfer belt off, clean the silver roller at the upper left, if that fails replace the belt or entire unit. My moneys on the id sensors being dirty/silver roller being crusted.

    Also, drums that have reached their life or beyond can cause faint chevrons used for color registration which in turn gives you the 285. First check: Pm counters for drums/dev units. Then check for worn out charge rollers in if the drums are still within pm limits.

    the manual said.

    SC 285 Line position
    adjustment
    (MUSIC) error
    Line position adjustment fails
    three consecutive times.

    causse
    Pattern sampling
    error due to
    insufficient image
    density of patterns
    used for the
    adjustment
    Inconsistency in the
    sampling line position
    adjustment pattern
    due to dust on the
    pattern, damage to
    the OPC drum,
    damage or toner
    dropped on the
    transfer belt, or a dirty
    or defective ID sensor

    1. Turn the main switch off and on.
    2. Check and fix the problem that
    causes low image density. .
    3. Clean or replace the transfer belt
    and/or the ID sensor.
    4. Replace the PCU or clean the
    development unit that causes toner to
    drop on the transfer belt.

    this said but I don`t know.

    Cleaning the ID sensors and the upper left roller is good but the AP3800 doesn't use this roller for reflecting the id sensor beam like the newer models.

    The AP3800 is old so I guess the transfer belt is wasted or maybe damaged by not correctly inserting one of it's units.

    It's also necessary that the machine is technically able to reproduce an adequate image density (for the ACC patterns).

    If one of the colors is to light, cause of no toner or developunit damage, the color registration don't work.
    If the registration failes and the marge is to high the machine can't set its self automatically.
    In SP mode You can do settings for main adjustment after that the machine is able to do the fine adjustments.
