I recently bought Magenta and Lt. Magenta chips for the Epson 4800 I recently acquired.
I bought it used to use a custom black ink set in it. I also have an Epson 4880 that I use for color printing.
For a trial run, my plan was to take a set of empty cartridges from my Epson 4880, which other than the magenta pair uses the same cartridges.
And clean and refill them with the new inks. Since I only had the 4880 magentas I bought the 4800 magenta and lt. magenta chips from you, and swapped them onto the 4880 magenta carts.
Unfortunately after doing this I received the invalid ink error on the magenta cartridges.
Over the weekend, I was was able to borrow a pair of the correct 4800 magenta cartridges the T606B and T606C.
The printer is perfectly happy with these cartridges. I then swapped the carts with the new chips into the printer and the error comes back.
Unfortunately I don’t have set of the old cartridges, the T5653 T5656 to verify that I can use those with the current epson T606x for the 4800.
The product pages specifically mention that your chips can be used to replace dead OEM chips. I read that as being able to work alongside other current OEM chips with the new part numbers.
<edit> It looks like Epson OEM chips have updated their nomenclature for 4800 series to 606C and B. You are correct!
LM (third party) should be T5656 and M should be T5653 and should work on the 4800. You have verified they are in the right position on your printer and that they are secured properly to the cartridge?
Yes, the chips are secure. They were fitted as shown in the video.
If I install the cartridges in the printer without the chips, it gives the No Ink Installed error instead.
I installed the chips one at a time, after checking the part number on the envelope.
When I received the error I removed the Lt. Magenta, put it back in the envelope and tried the magenta chip on the lt. magenta just to confirm. Still showed invalid ink.
I did not reset them, I have a different brand of resetter and didn’t want to mess up your chips.
