Epson R2400 printing Magenta instead of Yellow

[benBen]

I have since a month or so an Epson R2400
when I bought the printer it had clogged heads.
I soaked the heads and also injected them with ajax/windex
After that I placed refillable cartridges and the printer worked like a charm.
last week I made a print and at the and of the print, the last piece printed, ther was a magenta stain.
It was a pretty thick ink stain, so quite some ink came out at the same place.
I didn't print after that for some days and did a nozzle check some days ago
To my surprise ther was magenta in the yellow pattern.
So I printed some bold yellow text and the further the text advanced out of the printer, the mor magenta it became.
This tot the point that there wasn't yellow anymore and the text was completely magenta.
So today I toook the cartridges out and cleaned the heads with a bit of ajax/windex again.
The same thing repeated.
The beginning of the text had still some yellow in it but at the end it was completely magenta.
What could be the problem here?
Is my printhead broken?

If I recall correctly, the magenta sits next to the yellow in the R2400, right?
Maybe your magenta cart is leaking, contaminating the neighboring yellow, magenta is stronger anyway so even if it prints yellow normally, a tiny amount of magenta will turn it into more magenta than yellow...

 

[benBen]

Yes, yellow is next to magenta
But no the carts are not leaking
I thought it could be also something with wrong pressure in the cartridges

I had this stain thing happen with some cheap chinese refillable carts, whenever I filled them completely, reducing the amount of ink to ~60% resolved the problem.

If you want to make sure whether the fault is in the cartridges or the printhead, you can empty the magenta and, say, the cyan cartridges and use one in place of the other, if the problem is in the cartridge then you'll probably get similar problems, but this time with the cyan ink...

Well I somehow managed to get the machine running again
by cleaning the head and refilling the cartridges
Only a problem with the ARC chips now
In the middle of a print it stopped and isn't recognizing any cartridge anymore.

I downloaded sscserve.exe to reset the cartridges.
It installed on my W8 x64 PC but ssc service is unable to recognize or connect with my printer.
anybody ideas how to get the tooll working??
I set the tool as compatible with XP SP3

Windows 8 is a new beast that I haven't touched so honest answer is that I don't know...

You can't use the SSC to reset ARC cartridge chips though so it's probably a moot point regardless.

As for the ARC's... talk to your cartridge supplier and find out how you're meant to be resetting the ink levels. Normally you get to empty, pull the cartridge out and then replace... sometimes powering off is required as well.
