All Black Ink Cart not being read/accepted in Epson T3270

Cartridge no longer reading or throwing out an error on the printer panel? The chip could be expired or damaged needing replacement or it could be a “tank pressure” issue. See the steps below. 

STEPS:

1. If using the 3270 Refillable Photo Black cartridge and not reading in the printer, remove the cartridge from the printer.
   
   
2. With the cartridge out, remove the AIR-HOLE plug then place it back into the printer. Doing so will promote better air flow as the printer/cartridge may be experiencing a back pressure issue.
