Hi all,
the CT14I9 was successfully uploaded and activated on our Epson WF-C5290 printer.
When you go to 'Maintenance -> Print Quality Adjustment' and confirm with 'OK -> Print' the printer begins to check and then gives the 'Maintenance Error (Ink Supply Unit is not installed correctly)'. All fields for inkcolors are grey.
There is also a difference to the chipless firmware for the WF-5210: The WasteInkTank value is always full, on the WF-5210 it shows the correct value.
