Unfortunately, it is a somewhat common problem that a cartridge gets rejected by an Epson printer for no apparent reason. This may occur even when previously the printer accepted new replacement cartridges. The method below is highly effective and can be used for most printer brands, not only Epson. There is also a common misperception about compatible ink cartridges that Epson printers do not accept them, but that is simply not true.
Firstly, read carefully the message that is displayed as in some cases the printer is just asking if you want to continue to install this cartridge so this can be resolve by clicking “Continue” button at the bottom of the screen.
If, however, your message is clearly stating the cartridge is not recognised or is not compatible please follow the steps below:
1. Remove the cartridge/cartridges from your machine correctly with the printer on. If you are required to follow prompts on screen to change a cartridge make sure you do follow them, otherwise you should be able to simply lift the lid or press a specific button to get your carriage to slide across.
NEVER PULL the carriage across to change a cartridge as your printer will not realise anything has changed. All you will do is cause damage to your printer and potentially your poor fingers as well.
2. Turn your printer off and wait for a minute or so. Doing this will give your printer chance to clear the error it had and power down correctly. It may also be worth ensuring your printer is communicating this to your computer and that the error on screen has cleared.
3. Turn your printer back on and wait for it to settle down and warn of a missing cartridge. Taking an extra 30 seconds now may save you the time/ hassle of returning your cartridge or purchasing a new one.
4. Re-install the cartridge/cartridges individually. Please make sure that you follow any instructions given to you or follow the procedures described in the manual. If multiple cartridges have been rejected I would recommend installing them individually and ensuring the cartridge is being recognised by the printer before repeating the process for the next cartridge. If any cartridges are rejected remove them from the printer immediately and either replace with another from your stock or move onto the next colour.
There are a variety of different causes of Epson inkjet cartridges not being recognised, this could be as simple as chip is not correctly aligned in the printer or damaged chip. However by following the above steps you are effectively forcing the printer to reset the memory and check thoroughly for a new cartridge.
I hope this advice has helped, if however the problem continues then unfortunately it would appear you have a damaged, faulty or incompatible cartridge. In which case please simply get in contact with whoever the unit was purchased from to obtain a replacement.
