My MP530 suffered through a brownout, and half of the pigment black nozzles stopped working. In the process of troubleshooting, I power cycled the printer, and it wouldn't come back on. At first it got to "CANON" and then immediately shut off, then it wouldn't start at all.
Thinking that it was a bad power supply, I replaced it, but nothing happened.
I found a used 530 on craigslist and it tested fine, but the previous owner had been using third party ink, so I swapped the print head and cartridges for my own from the dead printer, which were genuine Canon. Bad idea. It printed one photo OK, but when I printed a head alignment sheet, it appeared to run out of ink mid page, and the pigment black was completely missing, despite full tanks. I ran deep cleaning several times, but the results stayed the same.
I swapped back the other head/ink set, and ran deep cleaning, and still no image. The paper feeds, the head moves, but nothing comes out.
In case there was a problem with the purge unit or the carrier electronics, I swapped the good logic board into my old printer. It started up, but the results were the same: no image, not even a faint/distorted one.
What happened? I assume my heads, as well as my logic board, were fried in the brownout. What electronics in the head could be so damaged as to damage the new board? Is there anything else I can try before I give up, conceding a lost $30 on the PS and $60 on the used perfectly good unit that I've now killed? I'm also perplexed by the failure mode of the heads, why would they work for a little while and then act like they'd run out of ink instead of being just completely dead?
