xx53 During copying sequence,
gain setting cannot be
performed because of an error
in the memory backup data
(the level of RGAN-P-M/C/Y/
K is '250' or more or '40' or
less).
xx60 During copying sequence, the
level of SGNL-M/C/Y set
initially is '777' or less
because of an error in the
memory backup data.
xx61 During copying sequence, the
level of REF-M/C/Y set
initially is '200' or less
because of an error in the
memory backup data.
xx62 During copying sequence, the
level of PT-REF-M/C/Y set
initially is '767' or less
because of an error in the
memory backup data.
xx63 During copying sequence, the
level of PT-SIG-M/C/Y is
'683 (CLC 1100/1120/1130/
1150)', '655 (the other)'
or that of PT-SIG-K is '305' or
less because of an error in the
memory backup data.
xx64 During copying sequence, the
level of PT-REF-D is '400' or
less because of an error in the
memory backup data.
xx65 During copying sequence, the
level of PT-SIG-D is '400' or
less because of an error in the
memory backup data.
xx66 During copying sequence, the
level of D-M-TRGT/D-C-
TRGT/D-Y-TRGT (developer
target value) is '700' or less
because of an error in the
memory backup data.
xx67 During copying sequence, an
error in memory backup data
causes the initial setting of the
following to be '256' or lower:
ADJ>DENS>P-SENS-Y/M/C/
K.
xx70 During copying sequence, the
level of SGNL-M/C/Y set
initially is '859' or more
because of an error in the
memory backup data.
