    Konica 7055 - desperate for help

    Upper fuser lamps don't cycle off, causing overheat error. New thermistors installed, continuity to control pcb checked, control pcb tested by hytec & no trouble found. What am i missing?

    DESCRIPTION: F34-1 shortly after warm-up.

    CAUSE: Failed DCPS board. The upper fuser roller heat lamp (L2) is not shutting OFF after copier has reached warm-up.

    SOLUTION: To confirm, verify L2 operation in diagnostics (power ON the copier while holding down the 4 and 7 keys). DO NOT press any output code. The fuser unit heat lamps (L2, L3 or L4) should NOT be lit. If any of the lamps are ON, replace the DCPS board (p/n 55FA84512).

      Don't forget to give some feedback so that we (and others that might find this problem in the future) know if this solved your problem or not.

      Cheers!
