Yellow seems much more like a laquer, while black seems more like pigments
without much resin. Dunno why but that's how it is.
BTW. i left the cheap aftermarket ink in the color carts. When the printer
starts mixing inks in some settings the blue is added to the black. This
ink mix is all runny and beads up. The mispro ink seems really a key
factor. Let's just hope they don't change the formulation, ever, or stop
selling it.
I just had a look at the C84 printer and removed all the pizza wheels. I
saw that it should be easy to do whatever one wants to this printer. The
paper drive stepper is linked to the vacuum cleaner pump by that main
drive shaft/roller (the one with the rough coating). Nothing else of any
significance is driven by the paper drive stepper. So the pump could be
disengaged completely and either replaced with a manual pump or some other
drive added (worst case just buy another c84 for 1eur and hack the motor
and gears to duplicate it). This would allow to have the drive stepper
only used to drive the paper, not in reverse mode for the pump. If one
wants to have a carriage engaged with the roller at all times it should be
possible to break connection to the wires of the stepper via transistors,
so it is only activated when you want to forward the carriage. Or maybe a
magnetic clutch will be easier to fit, i have some from a copier.
There seems to be only one lever operated optical sensor for the paper
detection on the back.
