Remedy: Thermistor (TH) Turn off the machine and remove CN103 from the Control PCB (PW10620). Is the resistance between CN103-4 and CN103-5 about 1.4M ohms to 2.2M ohms? No Check the wiring between CN103 to Thermistor (TH). If there is no problem, replace the Thermistor (TH) with the new one. Is the Thermistor (TH) pressed to the Magnet Roller evenly? Is it slanted or detached? No Install the Thermistor (TH) properly. Is there the dirt or the foreign substance on the Thermistor (TH)? Yes Clean it. Thermostat (TH1) Is the resistance of the Thermostat about 0 ohms? No Replace the Thermostat (TH1) with the new one. Heater Lamp (H1) Are both sides of the Heater Lamp connected properly? No Install the Heater Lamp properly. Is the Heater Lamp broken? Yes Replace the Heater Lamp with the new one. SSR Can you fix the problem when you replace SSR with new one? Yes OK. Control PCB (PW10620) Can you fix the problem when you replace the Control PCB (PW10620)? Yes OK.
Code: E2
Description: EEPROM Error
Causes: 1. Writing to the EEPROM is failed. 2. Reading the EEPROM is failed.
Remedy: EEPROM Turn off the machine once, and turn on the machine again. Is “E2” still indicated? Yes Replace the Control PCB (PW10620) with the new one. No Check the Backup Data and set the data again.
Code: E3
Description: Cutter Error (Time Over)
Causes: The Cutter does not stop working in 2 seconds after the Cutter starts to work.
Remedy: Cutter Part Turn off the machine. Rotate the Gear of the Cutter manually. Does the Cutter move properly? No Check if the there is the foreign substance, deformation or drop of the rotating teeth. Cutter Home Position Switch Turn off the machine. Does the Cutter Home Position Switch (SCUT T1, SCUT T2) work properly? No Check the wiring between CN105 and the Cutter Home Position Switch. Cutter Motor Control PCB (PW10620) Enter the Service Mode and select the Output Test 2 of the Function Checking Mode. (Refer to the page 8-31.) Does the voltage between the CN105-4 and CN105-5 on the Control PCB (PW10620) change momentarily? <Note> The Polarity of the voltage (0 to 24V) is inverted depending on the direction of cutter movement. No Check the wiring between CN105 and the Cutter Motor. If there is no problem, replace the Cutter Unit or the Control PCB (PW10620) with the new one.
Code: E4
Description: Cutter Error (Switch Abnormal)
Causes: The Cutter Home Position Switches (SCUT1 and SCUT 2) detect “1” while the Cutter is working.
Remedy: Cutter Part Turn off the machine. Rotate the Gear of the Cutter manually. Does the Cutter move properly? No Check if the there is the foreign substance, deformation or drop of the rotating teeth. Cutter Home Position Switch Turn off the machine. Does the Cutter Home Position Switch (SCUT T1, SCUT T2) work properly? No Check the wiring between CN105 and the Cutter Home Position Switch. Cutter Motor Control PCB (PW10620) Enter the Service Mode and select the Output Test 2 of the Function Checking Mode. (Refer to the page 8-31.) Does the voltage between the CN105-4 and CN105-5 on the Control PCB (PW10620) change momentarily? <Note> The Polarity of the voltage (0 to 24V) is inverted depending on the direction of cutter movement. No Check the wiring between CN105 and the Cutter Motor. If there is no problem, replace the Cutter Unit or the Control PCB (PW10620) with the new one.
Code: E6
Description: Pocket Door Error (Time Over)
Causes: The Pocket Door does not stop moving in 2 seconds after the Pocket Door starts to move.
Remedy: Pocket Door Part Turn off the machine. Rotate the Pocket Door Motor manually. Does the Pocket Door move smoothly? No 1. Check if the Rack Gear is overrun. 2. Check if the Lever of the Swing Plate comes off the Rack Gear. 3. Check if the Warm Gear and the Motor Output Spindle are fixed properly. Pocket Door Switch Turn off the machine, and rotate the Warm Gear manually. Are S19-1 and S19-2 the following status when the Pocket Door is closed? S19-1: OFF S19-2: ON Are S19-1 and S19-2 the following status when the Pocket Door is opened? S19-1: ON S19-2: OFF No Check the wiring between J19 to the Pocket Door Switch. If there is no problem, replace the Pocket Door Switch with the new one. Pocket Door Motor Enter the Service Mode and select the Output Test 2 of the Function Checking Mode. (Refer to the page 8-31.) Does the voltage between the CN104-4 and CN104-5 on the Control PCB (PW10620) change momentarily (within 2 seconds)? <Note> The Polarity of the voltage (0 to 12V) is inverted depending on the condition of the Pocket Door (open/close). No Check the wiring between CN104 and Pocket Door Motor. If there is no problem, replace the Pocket Door Motor or the Control PCB (PW10620) with the new one.
