xx4C
Backup data (DC controller PCB; error)
Be sure to execute RAM clear, and enter the
value recorded on the service label.
Initial settings may be missing.
During copying sequence, the average value after
sampling of the following values is 512 or lower: SGNL
SC, SGNLSM, SGNLSY; or, the value of SGNLS
K is 102 or lower.
xx4D
During copying sequence, the average value after
sampling of the following values is 336 or lower: REF
SC, REFSM, REFSY; or, the value of REFSK is
464 or lower.
xx4F SALT sensor (fault)
The value of 'SGNLSC/M/Y/K', which has been
obtained by averaging samplings during copying
sequence is 1008 or more.
xx50
SALT sensor (faulty)
Stirring (developer inside developing
assembly; faulty)
Stray light (to sensor; no cover, front cover
open)
Photosensitive drum (deterioration)
When setting initial data (upon installation, for example),
the gain cannot be set (i.e., no change is noted in the
value of SGNL between GAIN: 20H and GAIN: E0).
0455
An appropriate patch cannot be obtained when setting
initial data (e.g., at time of installation).
xx60
SALT sensor (dirt on window, damage)
Photosensitive drum (dirt; cleaning failure)
During multiple initial rotation (at poweron, for
example), the window cleaning correction value is 60%
or lower.
xx70
During multiple initial rotation (at poweron, for
example), the window cleaning correction value is 140%
or lower.
xx80
Backup data (DC controller PCB; error)
Be sure to execute RAM clear, and enter the
value recorded on the service label.
Initial settings may be missing.
During copying sequence, the initial setting for the
following is 848 or higher because of an error in the
memory backup data: SGNLSC, SGNLSM, SGNL
SY; or, the value of SGNLSK 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 backup data: REFSC, REFSM, REFSY;
or, the value of REFSK is 544 or higher.
xx82
Backup data (DC controller PCB; error)
Be sure to execute RAM clear, and enter the
value recorded on the service label.
Initial settings may be missing.
During copying sequence, the value of the following is
255 because of an error in the memory backup data:
SIGGSC, SIGGSM, SIGGSY, SIGGSK
xx85
During copying sequence, the initial setting for the
following is 512 or lower because of an error in the
memory backup data: SGNLSC, SGNLSM, SGNL
SY; or, the value of SGNLSK is 144 or lower.
