Epson is doing something very similar - printheads of lots of printers are coded - with a kind of serial number which carries individual technical parameters which are coded with a barcode, and such barcode label is attached to the printhead. When replacing such printhead you need to enter this...
I'm not clear why you are trying to print with the absolute colorimetric rendering intent; you are not doing any proof/soft proof type action under a specific environmental light condition to emulate a target paper on a proof paper. Since I'mnot using ArgyllCMS I cannot comment any further on...
Epson does something like a 'nozzle verification technology'
https://blog.flextg.com/what-is-nozzle-verification-technology/
The user manual of my ET-3100X is referring to it, but I don't know if I can even see whether it's working. Detecting individual nozzles not working is the easy part, but...
It's just impossible to make general statements ; you have to consider a particular ink type on a particular paper in a particular environment which let the inks fade faster or slower than other inks.
I did various tests which always was a kind of comparison with an Epson 106 ink type, and this...
The service/maintenance manual may give more insight, if and how the overspray pad could be replaced and a reset of a counter for that pad could be done.
Yes - since the ET-7750 comes with a user replaceable waste ink bin, and a new waste ink box comes with a new chip. That's the same with the ET-8550 not giving access to the waste ink status via WICReset. You should have access to the waste ink status via the printer screen menu - the...
I'm now running the Epson T3100X since a year, prints are very good and I didn't encounter any problems so far; I used about 2 - 3 130 ml refills varying by color. I did not encounter problems or functional issues beyond those which got discussed in this thread before. And I have an answer to...

I'm glad you found that difference with the prints , that's one of several hidden traps when doing profiling - but isn't that part of the fun with profiling ?
It is the job of a profile to compensate ink variations and to get the print output closer together as much as
different gamuts would allow. It was a promise by precisioncolors that the inks are as close as possible to the OEM inks so that a different profile would not be needed. If this is the...
