Digital BW, The Print

I've had the exact same problem with the VM cartridges on my 1280 
printer when printing in the neutral cold mode (I hope that's the 
right label, it's not the cold mode nor is it the two warm modes, 
it's the mode that's supposed to give basic black and white prints). 
I used to get very neutral black and white prints with my 1160 and 
maybe when I first got the 1280, I don't remember exactly when the 
problem started, but lately I've had to print everything in moderate 
warm mode because of this problem. I've been intending to call MIS 
about it but just haven't had the time lately.
