My Epson Workforce printer uses 252 cartridges. It no longer recognizes any black cartridge. I looked where the cartridge goes and it seems that in the bank of pins that contact the cartridge that one pin is missing.
Can anyone with the same printhead take a look and see if there are 8 pins or 9 pins in the black slot? I count 8 in mine, and 9 at the next slot over for the cyan cartridge.

The Epson chips are 9 pin, so likely one of the pins is missing on the chip reader IC. Take a photo of the pins, and we can confirm for sure. That said, it sounds like a damaged pin pending any extra pointers to better see.
The other thing I see a lot is 3rd party carts with bad clone chips, or failed OEM Epson chips that were reset (or the reset failed and it bricked the chip), OR the chip was at 25% capacity and the chip was write locked against resetting and the remanufactuer does not know that occurs with 88/68/99-present Epson chips. Multiple installations works on flaky 3rd party chips, but not a bricked OEM reset or hard locked OEM.
You could try another cartridge and see, but if 2 fail then you probably have damage at the printer side.

@dancealot here is the Epson WF 7620 SM for the actual printhead repair. Also, consider posting some images of what your "damaged" area look slike. Lets see if we can figure something out here. 在已经存在的问题里加入图片

@dancealot what is the exact model number for your Workforce printer. There are many different models. Let's see if our printer Guru @nick has any ideas ;-).

Definitely a pin missing. My LD cartridges didn't work, so just to make sure I spent a paycheck on Epson cartridges and that didn't work either.
Can I replace the printhead? Probably not worth the trouble just to use up all my Epson and LD cartridges and have 13x19 capability.
Definitely 8 pins there.

@dancealot It's not an easy job to replace, nor does Epson sell parts unless you can get a used reader from a pull, or a junk donor. I would look at the newer ET- units, notably the 15000 if you want A3/13x19. I know someone who makes comics who uses one for their business and it's a good unit with wide format support. They were between the 8550 and the 15000 when I mentioned both.
The 8550 is the photo grade model, the 15000 is CMYK. Unless you get a used 7620 which isn't clogged or has a high meter count with a waste ink pad that's nearing being full. They said she issue with the 15000 is volume - for me with that discussion the 15000 wins because I would use the extra colors. They needed volume.
@oldturkey03 I know this is a weird suggestion for me but wide format color lasers are expensive and very heavy. The 15000 is cheap in comparison and isn't a maintenance pig like so many 11x17+ color lasers. Nothing wrong with them with the right owner but I would never ever suggest wide format color laser first.
