Question about Canon Dr-7550c Color Duplex SCSI-Iii USB Scanner
Posted by Anonymous on
E046 Main drive PCB
(Controller CPU judgment)
If a communication error occurs between
the motor or sensor and PCB, an error
message appears. If it appears, reset the
main body and computer power. If the same
error message/code still appears, check the
connection of the related part, and if it is faulty,
correct it. If there is no problem with connections,
replace the related part. For motors,
check the connected drive transmission parts
and operation check sensor as well.
