Yesterday, I used my p4000 Epson printer without issues.
Today, I turned it on and the printer didn't recognize 3 ink cartridges-all of which are your manufacture.
This is not the 1st time this has occurred. Actually, it happens quite often. I have to fiddle with the cartridges( place cardboard in various places, etc.) multiple times b4 they are recognized by the printer.
The difference today is that after a lot of fiddling around, I've managed to get all BUT one to be "seen" by the printer.
It happens to be the CYAN ink Cartridge.
Guess I'll have to order a replacement chip.
But, that's not really going to solve the problem since it's the cartridge mold that really is the culprit. They are not manufactured properly and just don't fit well in the printer.
Frankly, after all the headaches, with these 3 cartridges, I really don't think I can recommend your product nor buy any additional ink cartridges from your company.
