If Dell have one for the 5110cn it's fairly well hidden.
If their competitors who do toners at half the price have one, I'd be 
very surprised.

Given the cost of toner when used in quantity, this is a significant 
issue. If you wanted things under CMS it certainly would be a good plan 
to have your own Huey or whatever.

An onerous task given the number of printers, ink providers and papers.

:)  I think I can cope, though we are just printing reports onto nice 
quality 100gsm office paper. Further, the errors I want to correct are 
gross enough that as long as the test paper is basically white, it would 
be good enough to see what's going on.  We use / recycle all sorts here.

That depends if you are paying a premium for paper from Ilford or 
whoever I guess.

Regardless of the cost of the instrumentation, having the option of 
adjusting curves for ad hoc work would be great from where I'm standing, 
and I suspect for many if not most users of DTP who are working outside 
of a CMS environment.

That certainly brings the instrumentation cost down.
