Digital BW, The Print

If it is the weekend, I must be printing. If I'm printing, I must be having
a problem.

My setup:

Epson 7600
Piezography in the 220 ml cartridges. Warm Neutral and Selenium sharing a
Museum Black through the StudioPrint RIP.

Late last night I went to hit the eject button after a print had been run
through and I think/assume/but not sure, I hit another button because the
print did not drop and there was an error message that read "Set Ink
Cartridge" and the "LM" panel light was on. I turned the printer off,
unlocked the ink lever, pulled that cartridge out and shoved it back in,
locked the lever and turned the printer on. The error message still showed
up and I can't find any documentation to correct it.

The  LM cartridge is about half full from what I remember seeing on the
level indicator on the front panel before this happened. The other strange
thing is that the LM position is one of my selenium cartridges and I had
been running the last five prints through with the warm neutral inks. Now
when I go into the Epson print utilities, it shows me that all of the ink
levels are full. This isn't true since I know I was about to run out of
"Museum Black" and the warm neutrals were at about 1/4. The selenium's were
at 1/2. I replaced the Museum Black with a full cartridge, turned it on
again and I still get the "Set Ink Cartridge" message.

As I am suppose to be finishing the prints for an exhibition that gets
delivered on Friday, any immediate help will be much appreciated. Since I
get this list in digest form, please respond to me offline at:
