Description
• The main thermistor (TH1) detects less
than 150°C for 200 ms after it has detect-
ed 150°C.
• The sub thermistor (TH2) detects less
than 150°C for 200 ms after it has detect-
ed 150°C.
• The output of the fixing film sensor contin-
ues to be '1' or '0' for 2.1 sec or more.
• The displacement is not corrected after
executing film recovery mode which turns
on when the main power is tuned off and
on in response to 'E007'.
• The main motor does not lock for 10 sec
after it is started.
• The value is outside a specific range, and
the main motor does not lock for 3 sec.
• A check is made immediately before the
counter turns on and off. (Normal, if the
counter drive signal is '0' when the
counter turns on.)
• A check is made immediately before the
counter turns on and off. (Normal, if the
counter drive signal is '0' when the
counter turns on.)
• The count data is not detected by the
Copy Data Controller within a specific
period of time after the copier has gener-
ated the copy start signal.
• The home position is not detected after
generation of the horizontal registration
drive signal.
