If there has been a full set of genuine cartridges installed in the printer prior to installing the new compatible cartridges then a full compatible cartridge replacement may be required if the error message (Cartridge is not compatible) appears
If this error message still appears after this troubleshooting or you don't have a full set of compatible cartridges available please consult the "Problems you might encounter" section below
- This incompatible cartridge error message appears when the printer detects that there is both genuine and compatible cartridges installed in the printer
- To do a full genuine to compatible replacement please follow the steps below:
-
- 1. Remove all the cartridges currently installed in the printer and turn the printer off. Leave it off for 15 minutes then turn it back on
-
- 2. Re-install a full set genuine Epson ink cartridges in the printer - These genuine cartridges can be half full or even empty
-
- 3. Once the genuine cartridges have been detected, remove and the replace them with compatible cartridges.
-
- 3a. Note: This must be done in one go
Problem: Cartridge is not compatible
The compatible cartridge has been installed correctly and the error message (Cartridge is not compatible) has appeared
Resolution
- 1. Remove the affected cartridge/cartridges from the printer
- 2. Turn the printer off and wait for 2 minutes
- 3. Turn your printer back on and wait for a further 2 minutes
- 4. Once the printer warns that certain cartridge/cartridges are missing, re-install them one at a time
Problem: Printing blank pages
The ink cartridge printed one or two pages and then stopped printing.
Resolution
- It could be that the tape that covers the breathing hole has not been removed
- Be sure the breathing hole on the cartridge has been released usually by removing a small “rip strip” so that the cartridge has air supply then it can print.
Problem: Cartridge is the wrong size
The cartridges are physically a different size or shape.
Resolution
Compatible cartridges will always look different to the original branded cartridges
They will often differ in shape or size but this does not affect the fitting or functionally of the cartridges in any way at all
- Ensure the Seal is pierced when installing by giving the cartridge a firm push upon installation
