Code
E020
Cause
• SALT sensor (faulty)
• Stirring (developer inside devel-
oping assembly; faulty)
• Stray light (to sensor; no cover,
front cover open)
• Photosensitive drum (deteriora-
tion)
• SALT sensor (soiled window,
damage)
• Photosensitive drum (dirt; clean-
ing failure)
Description
xx3B The variation of the following is 47 or
more for 5 samplings of the density
data when sampling during copying
sequence:
REF-S-Y, REF-S-M, REF-S-C, REF-S-K
xx40 When setting initial data (upon installa-
tion, for example), the average value
after sampling of the following values is
848 or higher:
SGNL-S-Y, SGNL-S-M, SGNL-S-C,
SGNL-S-K; or,
the value of SGNL-S-K is 352 or
higher.
xx41 When setting initial data (upon installa-
tion, for example), the average value
after sampling of the following values is
848 or higher:
REF-S-Y, REF-S-M, REF-S-C, REF-S-K; or,
the value of REF-S-K is 544 or higher.
xx42 When setting initial data (upon installa-
tion, for example), the value of the
following is 255:
SIGG-S-Y, SIGG-S-M, SIGG-S-C, SIGG-S-K
xx43 When setting initial data (upon installa-
tion, for example), the gain of the SALT
reference signal for each color is 255.
xx45 When setting initial data (upon installa-
tion, for example), the average value
after sampling of the following values is
512 or higher:
SGNL-S-Y, SGNL-S-M, SGNL-S-C; or,
the value of SGNL-S-K is 144 or lower.
xx46 When setting initial data (upon installa-
tion, for example), the average value
after sampling of the following values is
400 or less:
REF-S-Y, REF-S-M, REF-S-C; or,
the value of REF-S-K.
xx47 When setting initial data (upon installation,
for example), the average value after
sampling of the following values is 0:
SIGG-S-Y, SIGG-S-M, SIGG-S-C,
SIGG-S-K.
xx48 When setting initial data (upon installa-
tion, for example), the average gain
after sampling of the SALT reference
signal for each color is 0.
