We have a slew of these still left in the field. We used them to fill huge gaps in Sharps product line (desktop MFP and color. C'mon Sharp, your line up sucks!!)
CX2033, 2037, and a few MPS 420 and 480 mono machine.
We ran into an issue where a print driver could not be shared over the network...WTF is that all about!?
They seem to have 3 manuals, the service guide, parts, guide, and maintenance manual. All the .pdf files are very old and not a single bookmark...yay!
I too have tried to order simple consumables, like toner and drums, and have also been told it is not a valid number. These clowns don't even know their own part numbers!!!
I will say the models we service tend to run well with the exception being fuser failures. When not on constant back-order, I like to keep them in stock.
