DESCRIPTION: F34-1 shortly after warm-up.Originally Posted by JERRY D
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!
