Was it REALLY
that much easier to poke holes in it, instead of opening it?
You know, this is activating some very dusty neurons as this was the
late 1980s when we were doing this, but I don't recall there being any
other way to access the toner reservoir. Sure, there were torx screws
in there, but I don't remember any of them opening up the reservoir. If
there had been, we'd have done it; we refilled many hundreds of CX
cartridges.
Logically, there has to be a way to fill the toner reservoir, since that
was done at the factory. The plastic wasn't moulded with the toner inside
it :-)
From what I rememebr (and I may be mixing it up with
the SX cartridge),
you can get the outer cassing off with the torx screws and some
plastic
barbs, then the thing spits in half at the drum. One half is the waste
toner collector -- which you empty [1], the other is the toner reservoir
which you can somehow get inside and refill. If anyone is seriously
interested, I'll dig out a cartridge and take it apart.
[1] This was certainly an SX story... A friend and I took apart his SX
cartridge, and decided to empty the waste toner out of it. He did so into
a toilet. We then discovered that toner flats on water, and the darn
stuff would not flush away. I then suggested adding a little washing-up
detergent, This worked after a number of flushes, you get this odd black
foam in the process...
