Alright, so it was time to disassemble and clean my rollers and such. This is not the first time I have done this.
After I was done, I reassembled. I triple checked that all connections were in the right place, etc. I plugged in the USB cord first. Then the AC cable. I head the Windows sound indicating I plugged something in, and then I lost power to the printer. Now it won't turn on at all.
I'm trying to figure out if the PSU is dead. I can see the voltage pin assignments on the bottom of the PSU. I took a multimeter to it and tested for some. I get +3.3V for the logic board. None of the other pins give me the correct reading. Pins 4 & 5 give me 10.6V across GND. I'm assuming these are all DC.
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
Can someone with an i9900 check theirs to see if I should be seeing the above with my meter? I don't want to order a $60 PSU if it isn't going to fix it. I just got new inks, blanks, and 2 new printheads!
