Back up 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.

Cause
When setting initial data (upon installation, for example),
the aver age value after sampling of the following values
is 848 or higher: SGNL S C, SGNL S M, SGNL S Y,
SGNL S K; or, the value of SGNL S K is 352 or higher.
When setting initial data (upon installation, for example),
the aver age value after sampling of the following values
is 848 or higher: REF S C, REF S M, REF S Y, REF S
K; or, the value of REF S K is 544 or higher.
When setting initial data (upon installation, for example),
the value of the following is 255: SIGG S C, SIGG S M,
SIGG S Y, SIGG S K
When setting initial data (upon installation, for example),
the gain of the SALT reference signal for each color is
255.
When setting initial data (upon installation, for example),
the aver age value after sampling of the following values
is 512 or higher: SGNL S C, SGNL S M, SGNL S Y;
or, the value of SGNL S K is 144 or lower.
When setting initial data (upon installation, for example),
the aver age value after sampling of the following values
is 336 or less: REF S C, REF S M, REF S Y; or, the
value of REF S K is 464 or lower.
When setting initial data (upon installation, for example),
the aver age value after sampling of the following values
is 0: SIGG S C, SIGG S M, SIGG S Y, SIGG S K.
When setting initial data (upon installation, for example),
the average gain after sampling of the SALT reference
signal for each color is 0.
During copying sequence, the average value after
sampling of the following values is 848 or higher:
SGNL S C, SGNL S M, SGNL S Y; or, the value of
SGNL S K is 445 or higher.
During copying sequence, the average value after
sampling of the following values is 848 or higher:
SGNL S C, SGNL S M, SGNL S Y; or, the value of
REF S K is 544 or higher.
