Difference SHARP "A" and "C" Toner

[pdy-pt]

What is the difference between MX-61GT-BC and MX-61GT-BA toners on the European market? Both versions are available here.

THANKS!!

MX-61GTBA 100% content for 40k
MX-61GTBC 50% content for 20k

MX-61GTBC 50% content for 20k

That is incorrect, BA is 100%, BB is 50% and BC would be 100%, that is for Sharps own contract machines and will not run on regular machines as a firmware update is required (not available as far as i know) the first letter meaning black.

So the firmware for the C toner is nowhere available?

"will not run on regular machines"
We have some C toner (for whatever reason) and they run fine on our units.

(for whatever reason) May have been looked after by Sharp at some point??
