Canon PRO-10S suddenly stuck in alternating orange/white blink after maintenance

[Spetzbob]

No one can fix a Canon print head, not even Canon Inc. themselves..

Hm, my theory is that my fiddling around with cables and connections with multiple power offs and ons might have done something with the eeprom on the print head, so i want to take a Peek at it to see if there is any lockouts activated in its programming.

the printer works fine i think… if i take out the printhead, the error goes away so i guess its the head that is broken so i figured it’s worth a try reading the eeprom

The B200 error is sometimes intermittent before becoming permanent. That's why cleaning or other procedures sometimes seem to repair the printhead.

I see, I’m cleaning and cleaning, so far no results, so far it seems to be permanent or atleast persistent.

But I’ll keep going

The firmware on the print head is ROM only, so if you find an issue with it, there’s no access allowed..
