Hello, and thank you for using this service.
I will help you now.
Have you refilled a cartridge, or replaced with an aftermarket brand cartridge?
Did the light flash and problem start after you changed the black in cartridge?
Sorry, I don't have enough information on the situation with cartridge and your printer, and so have run out of ideas. Will opt out to other experts. Thanks.
Hello, I’m Nathan, and I’ll be assisting you today.
Sorry to hear that you’re having trouble with this but I’ll do my best to help you out.
Do you have any other cartridges there that you can replace the black with again?For how long have you been using these cartridges?
Well the current ink cartridge is almost certainly the root of the issue here.
The generic ink products are specifically prohibited by epson, as they tend to have high failure rates (they are defective right out of the box about 40% of the time) and actually cause damage to the printer. As a next step here, it will be necessary to replace the ink cartridge again, preferably with a new genuine epson one. Let me know the results after doing so, please.
