Mesin Digital pada umumnya telah dilengkapi system memory dimana terdapat semua kode - kode kerusakan yang mengalamatkan ada gangguan pada sensor.CPU pada control utama dan CPU pada controler DC dimana tujuannya untuk mempermudah menganalisa dibagian mana yang sedang mengalami gangguan/kerusakan,berikut adalah daftar kode error serta daerah komponen yg bermasalah.
E- 000
The main thermistor (TH1) has poor contact or an open circuit. The thermal switch (TP1) has an open circuit. The fixing heater has an open circuit. The SSR is faulty. The DC controller PCB is faulty.
E- 001
The main thermistor (TH1) has a short circuit. The sub thermistor (TH2)
has detected overheating. The SSR is faulty. The DC controller PCB is
faulty.
E- 002
The main thermistor (TH1) has poor contact or an open circuit. The thermal switch (TP1) has an open circuit. The SSR is faulty. The DC controller is faulty.
Mode of Detection
0000 The temperature of the upper fixing roller does not reach 100°C within 2 min after it has exceeded 70°C.Caution The error must be reset in service mode (COPIER>FUNCTION>
CLEAR>ERR).
E- 003
The main thermistor (TH1) has poor contact or an open circuit. The thermal switch (TP1) has an open circuit. The fixing heater has an open circuit. The SSR is faulty. The DC controller PCB is faulty.
Mode of Detection
0000 The temperature detected by the main thermistor is 70°C for 2 secor more after it has reached 100°C. Caution The error must be reset in service mode (COPIER>FUNCTION>
CLEAR>ERR).
E- 004
The SSR has a short circuit. The DC controller PCB is faulty.
Mode of Detection
0000 The SSR used to drive the fixing heater is found to have a short circuit (hard circuit detection).Caution The error must be reset in service mode (COPIER>FUNCTION>
CLEAR>ERR).
E- 005
The fixing web has been taken up. The fixing web length sensor (PS45) is faulty. The DC controller PCB is faulty.
Mode of Detection
0000 The length of fixing web that has been taken up is in excess of the specified length.
Caution After replacing the fixing web, be sure to reset the two web counters in service
mode: COPIER>COUNTER>MISC>FIX-WEB and COPIER> COUNTER>DRBL-1>FX-WEB.
E- 010
The main motor (M2) is faulty. The DC controller PCB is faulty.
Mode of Detection
0000 The clock pulses do not arrive for 2 secs or more after the main motor drive signal (MMFG) has been generated.
E- 012
The drum motor (M1) is faulty. The DC controller PCB is faulty.
Mode of Detection
0000 The clock pulses do not arrive for 2 secs or more after the drum motor drive signal (DMFG) has been generated.
