I know this was posted previously but I cannot reply/add to the thread. I am hoping someone can shed some light on the problem.
When inserting all 11 ink cartridges on our EPSON 7900, I get "Ink Cartridge Error Replace Cartridge" message with X on all cartridges. If any cartridge is removed, leaving 10 cartridges inserted, the printer will recognize all 10 cartridges including ink levels and the removed cartridge will show X as missing cartridge. This result is the same removing any single one of the 11 cartridges and leaving any 10 inserted.
Additional info
We have used both EPSON original and aftermarket cartridges.
We replaced:
Sub Board Assembly
Ink System Unit
Main Board
Pressurizing Unit
Any idea or comment is welcomed and appreciated, we have run out of ideas. Thank you so much!
