If anyone here has a Canon i9900, I would like to ask if you might have a few minutes to meter your power supply and tell me the readings you get between ground and each pin with the printer off and on.
You can do this without opening the printer by just removing the power supply from the bottom and disconnecting the power supply cable that goes up into the printer.
I have another post here explaining that I am troubleshooting my i9900 not powering on and need to figure out if it is the PSU or the logic board. It doesn't turn on at all, and I do NOT get the detect hardware sound in Windows when I attach USB and power. Usually you hear this after attaching power without turning on the printer.
If anyone here has an i9900 and can do this for me, I would gladly return the favor in any way possible. I do have the i9900 service manual if you need that.
The pinout is as follows:
1. +27V
2. +27V
3. GND
4. +20V
5. +20V
6. GND
7. GND
8. +20VENB
9. +27VCONT
10. +3.3V
Thanks!
