Guess I let this printer sit too long. The PGBK (big black) cartridge produces no output --- the test page has 6 colored strips including the BK at the bottom (kind of pale but they exist), but nothing at the top, where the PGBK should be. I'm assuming the problem is a clogged nozzle. I have tried a new genuine-Canon cartridge, have run "deep clean" many times, and have even filled an old PGBK cartridge with rubbing alcohol (70% ABV) and run "deep clean" with that. Still no black printing.
Any suggestions? The advice I've seen are (from Canon) "deep clean" and (not from Canon!) the alcohol. I've done both, with no success.
