I have a new to me Epson 7800 pro. It is in pretty good condition but am troubleshooting the cyan and light cyan looking mostly like green when printed from any computer. When I print any of the printer test pages the cyan and light cyan look perfect.
I upgraded the the firmware recently.
When I print a nozzle check I only get 4 colors squares instead of 8. Any idea why this is? It did the same before I updated the firmware.
