At first glance I notice the five pads which are the same node, upper-right in this picture.
So are those one of the DC rails, or are they ground?
I don't know the connections for the print head but maybe the print head expert @Łukasz knows?

and now i need an EEPROM-Image
1. If ceramic plate is detached from printhead body, then nozzles are filled with dust already.
2. Is there short-circuit condition in printhead (U052, B200)?
3. There is no need to detach memory tag (EEPROM) from green plate, signals pins are directly wired to connector.
4. EEPROM programing cures nothing in terms p. 2. (once seen bad EEPROM content after working in printer with unstable RAM memory).

Your wasting you time trying to figure the pinouts on a Canon print head, because you can’t print without having all the colour cartridges present, even if you only wish to print using the black cartridge.

Besides a B200 error usually means your print head has developed a problem that can’t be fixed, you may look for a new printer as the best option, sorry..

Indeed.

As long as the printhead is operational you can prolong its life by masking the contacts of the nozzles starting to fail.
Depending on what is left you can indeed use the printer for B&W or color photo only.

Thanks again to Lukasz, it helped in the past.
