Pixma Pro 100 Blinks 4 times HC00 Error. Print head does not appear to recognize ANY cartridge leve

[csstksue]

I swapped out the C cartridge as I usually do. Did not get the genuine ink installed message (I only use Canon cli-42. no off brands). I was able to print one item - but now printer just repeatedly blinks 4 times. Turned off/on Multiple times. Tried resetting print head as described in another message board. Still blinks 4 times. The strange thing is the printer head mechanism does not even slide to middle when I open the printer as if to change a cartridge, and now the printer utility shows none of the ink cartridge levels can be verified. I even swapped out the C cartridge again. No change.

Any ideas to try and fix? It has worked absolutely flawlessly for last 4-5 years - really hate to think it crossed the Printer Rainbow Bridge so suddenly! Thanks! Sue
