1. When the self diagnosis mechanism has detected an error, you may reset thecopier by turning off its switch once.This, however, does not apply to ‘E000’,‘E001’,‘E002’,‘E003’ and ‘E800’. To resetthese error codes, select No.401 in service mode [4], and press the OK key. Thisarrangement is adopted to prevent the user from casually resetting the copierwhen the cause of the error is an open circuit in the thermistor, thereby protectingthe rollers inside the fixing assembly against heat damage.2. If ‘E000’,‘E001’,‘E002’,‘E003’, or ‘E004’ is detected, the copier forces off thepower switch in about 2 sec.11-182CHAPTER 11 TROUBLESHOOTINGCOPYRIGHT © 1997 CANON INC.
