Canon PC900S Manual Do Utilizador

The microprocessor on the machine’s DC controller PCB is equipped with a self diagnostic

mechanism that checks the condition of the machine (particularly, sensors) and indicates an error
code in the count/ratio indicator on the control panel upon detection of a fault.

In the case of ‘E001’, ‘E0’ and ‘01’ are flashed alternately.

Code

Cause

Description

‘E000’, ‘E001’, ‘E002’, or ‘E003’ has
occurred.

• The thermistor (TH1) is faulty.
• The fixing heater (H1) is faulty.
• The thermal fuse (FU2) has blown.
• The DC controller PCB is faulty.
• The composite power supply PCB is

faulty.

• The thermistor (TH1) is faulty.
• The DC controller PCB is faulty.
• The composite power supply PCB is

faulty.

• The thermistor (TH1) is faulty.
• The fixing heater (H1) is faulty.
• The thermal fuse (FU2) has blown.
• The DC controller PCB is faulty.
• The composite power supply PCB is

faulty.

• The thermistor (TH1) is faulty.
• The fixing heater (H1) is faulty.
• The thermal fuse (FU2) has blown.
• The DC controller PCB is faulty.
• The composite power supply PCB is

faulty.

The power switch is turned off and then
on immediately after an error (‘E000’,
‘E001’, ‘E002’, ‘E003’) has occurred.
• The temperature detected by the

thermistor (TH1) does not reach 65°C
1.5 sec after the Copy Start key has
been pressed.

• The temperature detected by the

thermistor (TH1) does not reach 150°C
4 sec after the Copy Start key has been
pressed.

• The temperature detected by the

thermistor (TH1) exceeds 230°C.

• The temperature detected by the

thermistor (TH1) exceeds by 30°C or
more.

• The temperature detected by the

thermistor (TH1) registers an increase
of 100°C or more within 1 sec.

• The temperature detected by the

thermistor (TH1) registers an increase
of 40°C or more after it has reached
100°C during standby.

• E0 detection signal (E0_DT) is de-

tected twice or more in succession.

• The temperature detected by the

thermistor (TH1) has exeeded 150°C
during copy operation and maximum
power is applied for 10 to 14 sec
thereafter.

• The temperature detected by the

thermistor (TH1) drops to and remains
150°C or lower after it has reached
160°C.
