I have an Epson Stylus TX115. I recently changed the black cartridge with an original one, but it didn't print that good. Seemed that the printer was dirty or something.
I took out the cartridge and cleaned the ink sockets by blowing air with a syringe (since the print head cleaning didn't work). When I plugged the cartridge back in, the printer stopped recognizing it as original.
What could have happened for the printer to stop recognizing the cartridge and how could I fix this?
