After an initial and uneventful setup and series test printing, 24 hours later the 9900 front panel is flashing Red X's for all 11 ink carts with "Ink Cartridge Error Replace Cartridge." After re-seating all carts a few times, the error persists. The software utility sees the printer, but is unable to interrogate the ink levels, unsurprisingly. Epson tech support has never seen this error, I'm told - meaning with all 11 carts flashing red. Epson says it's usually a matter of a single cart fault, and the front panel notes the offending cart.
Thoughts?
