Re: Canon ir 3570 no power
I would first remove the Memory>clean ends & re-seat--
other info is below
When you turn on the machine there is no power up sequence, no LCD display, and the control panel Green LED is on. The All-Night Power Supply protection circuit may be shutting off power to all loads. The RMT1 and RMT2 signals are used to trigger the protection circuit and disable the power supplies. (Refer to page 10-16 in the service manual for an explanation of the Protection Function)
Solution :
The RMT1 signal can be verified by using the following procedure:
Note: You must make these checks in this order for the stated conclusions to be accurate.
Checking RMT1 Protection Circuit Signal
1) Power On the machine and visually check the Green LED (LED1006) on the Main Controller PCB. If LED1006 is Lit, the failure is NOT in the RMT1 Protection Circuit. If LED1006 goes On then Off, go to the next check.
2) Check the Main Controller PCB connector J1020 pin 5 to GND and pin 6 to GND. (To test DC voltage you can use the metal chassis of the machine as your GND connection.) If 3VDC is measured at connector J1020 on either pin 5 or 6, the failure is not in the RMT1 Protection Circuit. If you do NOT measure 3VDC at connector J1020, go to the next check.
3) Check the Controller Power Supply PCB connector J216 pin 9 to GND and pin 10 to GND. If 3VDC is measured at connector J216, the failure is in the wiring between J216 and J1020. If you do NOT measure 3VDC at connector J216, go to the next check.
4) Set your meter to read AC Voltage. Check the Printer Power Supply connector J1301 pin 1 to pin 3 for 115VAC. If 115VAC is measured at connector J1301, the failure is not in the RMT1 Protection Circuit. If you do NOT measure 115VAC at connector J1301, go to the next check.
Note 4: J1301 on the General Circuit Diagram is J301 on the Printer Power Supply PCB
5) Check the AC Driver PCB Connection WH102 (Hard wired) across the White wire to the Black wire for 115VAC. If 115VAC is measured at connector WH102, the failure is not in the RMT1 Protection Circuit and you should confirm the wiring between WH102 and J1301. If you do NOT measure 115VAC at connection WH102, go to the next check.
Note 5: The Green LED on the Control Panel is lit as part of our symptom. Therefore, there must be 115VAC on the AC Driver PCB.
6) Set your meter to read DC Voltage. Check the AC Driver PCB connector J209 pin 3 to GND. If 3VDC is measured at connector J209, the failure is not in the RMT1 Protection Circuit and you should replace the AC Driver PCB. If you do NOT measure 3VDC at connector J209, go to the next check.
Note 6: Measuring 3VDC at connector J209 confirms 115VAC is being supplied to the All Night Power Supply. Losing the 115VAC input to the All Night Power Supply will cause the 3VDC RMT1 signal at J209 to be zero.
7) Check the All-Night Power Supply PCB connector J692 pin 1 to GND. If 3VDC is measured at connector J692, the failure is in the wiring between J692 and J209. If you do NOT measure 3VDC at connector J692, go to the next check.
8)Check the All-Night Power Supply PCB connector J693 pin 1 to GND. If 3VDC is measured at connector J693, check the All Night Power Supply 115VAC input at connector J681.
Note 8: Any loss in 115VAC to the All Night Power Supply will generate the RMT1 Protection Circuit condition. You will need to confirm whether the AC Driver PCB (Hard connection at WH101) is failing to provide the 115VAC or the wiring to J681 on the All Night Power Supply is broken.
If 115VAC is measured at J681, AND the 3VDC is at J693, replace the All Night Power Supply PCB. If you do NOT measure 3VDC at connector J693, go to the next check.
9) Check the Main Controller PCB connector J1021 pin 3 to GND. If 3VDC is measured at connector J692, the failure is in the wiring between J693 and J1021. If you do NOT measure 3VDC at connector J1021, replace the Main Controller PCB.**Knowledge is time consuming, exhausting and costly for a trained Tech.**

Re: Canon ir 3570 no power
Many times a reseat of the boot rom will correct the problem. This is true across the line from 2016 to 5185 I have seen and stopped this problem.Comment

Re: Canon ir 3570 no power
My country is 220 - 240v
Ive checked for that and it is 220V
does the green light have anything to do with the HDD?Comment

=============
Location/Removing the Boot ROM
/Push the locking lever [1], and detach the Boot ROM [2]
BOOT ROM.JPG
be careful of your personal static electricity /power off printer>remove plug from outlet>dissipate your static (rub hands on printer metal frame/ or use static wrist band w/clip on to metal frame) before removing boot rom
