Digital BW, The Print

After flushing the original Ultrachrome ink from my Epson 7600 with the Jet
Jrano Flushing Fluid kit, I installed a complete set of 220ML Piezography
ink cartridges (Warm Nuetral & Selinium with Museum Black). After inserting
all seven ink cartridges and locking the ink lever, I get the following
message: "wrong ink cartridge". Looking at the Ink Jet Mall web site I see
instructions for changing the ink cartridge size in the menu for the Epson
7000/7500/9000/9500, but none of these work for the 7600. I am dead in the
water until I get this figured out. Please help soon. Since I get the list
in digest form, a direct post back to me will be very much appreciated.

Thank you,

Mark Maio
