ERROR CODE
E-7
E020
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-C, SGNL-S-M, SGNL-S-Y; 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-C, REF-S-M, REF-S-Y; 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-C, SIGG-S-M, SIGG-S-Y, 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-C/M/Y/K’ which has been obtained by aver-
aging 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.
Cause SALT sensor shutter (fault)
Description
xx90 Extreme changes have occurred in the window soiling correction
value 10 times or more.
xx91 An error has occurred in the data 10 times or more as a result of
window soiling correction.
Cause • Developer (deterioration)
• Developing cylinder (rotation failure)
• Developing assembly (locking failure)
• Toner density sensor (faulty)
• Developer (inside developing assembly; stirring failure)
• Toner level sensor (faulty)
Description
xxAA During copying sequence, the variation in 5 samplings of the fol-
lowing values is 47 or higher:
SGNL-C, SGNL-M, SGNL-Y
xxAB During copying sequence, the variation in 5 samplings of the fol-
lowing values is 47 or higher:
REF-C, REF-M, REF-Y
xxB0 When setting initial data, the average after sampling of the follow-
ing values is 859 or higher:
SGNL-C, SGNL-M, SGNL-Y
