Epson DX7400 not accepting non standard inks

Here is a link to the user manual. https://files.support.epson.com/pdf/cx74__/cx74__qr.pdf

It sounds like the cartridge chips are incompatible so you've probably been sold/sent the wrong cartridges.

It's possible that the printer you have is a later version with an updated firmware which has been programmed to refuse cartridge chips that were compatible with the first printers produced of this model but as the CX8400 is a relatively old printer I'd be a bit surprised if that were the case.

It's also possible that the cartridge chips are badly aligned, soiled (ie: dirty), or that the contact wires in the printhead (the thin/delicate wires that make contact with the chip when the cartridge is installed) are damaged.

Easiest way to tell if the cartridge chips are the problem though is to get a completely different cartridge, preferably some originals and see if they are accepted or not.

Hope that helps.

I have a similar problem. I accept the Epson notice that a non-standard cartridge is in place, but it still refuses to work.

It is as simple as below.

Open up the hood of your printer.
Switch on the printer.
The cartridge will come in the centre to remove.
Press at the back of the cartridge and slowly remove it.
While installing the new one follow the reverse process.

Thanks

Hi, did you find a solution to this question as I have the same problem, can't find the Agfa cartridges anywhere.

Sorry to be the bearer of bad news but no...

The DX4200 uses:
Black T0611
Cyan T0612
Magenta T0613
Yellow T0614

... while the DX4400 uses:
Black T0711
Yellow T0714
Magenta T0713
Cyan T0712


Best bet is to eBay them or find someone who wants to trade.

Hope that helps.

Hi Col,

The reality is that yours is an all too common story, the problem is with the type of ink. Your printhead in your printer is a very sensitive little peice of electronics and they tend to react badly to the wrong type of ink. I know that the fool who sold you the ink assured you that it will work as well as the genuine article, (I have heard all this before on many many occasions), but the fact is that the ink inside the genuine epson cartridge is covered by an international patent and cannot be used by anyone other than epson.
To cut a long story short, the non genuine inks are diluted in order to pass through the print head. As a result they tend to also dry very quickly and tend to destroy the head. The best solution I can offer you is to go out and buy a genuine cartridge and hope that it fixes the print head. You will have to install it and try to clean the head.
There are some methods you can use to try to speed up the process, but get your replacement cartridge first and try to do a head clean first. This will hopefully fix your problem.

My Epson R285 will not recognise compatible cartridges,mainly the black.I ran out of black ink and installed a compatible cartridge but it did not recognise it.To get the printer running I had to buy a genuine one which worked.I then ran out of all the other colours soon after and installed compatible ones which were accepted.I have now ran out of the black again but the printer will not accept the compatible cartridge.How can I solve this problem as the printer has accepted black compatibles before.
Thanks Padgy

I have an Epson dx 7450 scanner printer that will not accept non epson so called compatibles .Anyone found a solution ? I've tried a number of manufactuers and they all don't work . I really don't want to fork out for epson inks ?
