Cause
Back-up data (DC controller PCB;
error)
Be sure to execute RAM clear, and
enter the value recorded on the
service label.
(Or, initial settings may be missing.)
Description
xx80 During copying sequence, the initial
setting for the following is 848 or higher
because of an error in the memory
back-up data:
SGNL-S-Y, SGNL-S-M, SGNL-S-C; or,
the value of SGNL-S-K is 352 or
higher.
xx81 During copying sequence, the initial
setting for the following is 848 or higher
because of an error in the memory
back-up data:
REF-S-Y, REF-S-M, REF-S-C; or,
the value of REF-S-K is 544 or higher.
xx82 During copying sequence, the value of
the following is 255 because of an
error in the memory back-up data:
SIGG-S-Y, SIGG-S-M, SIGG-S-C,
SIGG-S-K
xx85 During copying sequence, the initial
setting for the following is 512 or lower
because of an error in the memory
back-up data:
SGNL-S-Y, SGNL-S-M, SGNL-S-C; or,
the value of SGNL-S-K is 144 or lower.
xx86 During copying sequence, the initial
setting of the following is 336 or lower
because of an error in the memory
back-up data:
REF-S-Y, REF-S-M, REF-S-C; or
the value of REF-S-K is 464 or lower.
xx87 During copying sequence, the value of
the following is 0 because of an error in
the memory back-up data:
SIGG-S-Y, SIGG-S-M, SIGG-S-C,
SIGG-S-K.
xx88 During copying sequence, the data on
the light (in the absence of toner)
reflected by each photosensitive drum
is 16 or lower because of an error in
the memory back-up data.
xx89 During copying sequence, the data for
window soiling correction is 16 or lower
because of an error in the memory
backup data.
xx8A The value of ‘;REF-S-Y/M/C/K’ which has
been obtained by averaging samplings
setting initial data is 16 or less.
xx8F During copying sequence, the gain of
the SALT reference signal for each
color is NOT 128 because of an error
in the memory back-up data.
