Today I emptied out the toner recovery box from my Konica C500. First let me say I'm astounded at the amount of toner that gets wasted. I HATE that. This stuff is ridiculously expensive even on EBAY, when I'm lucky enough to find it there when I need it. Anyway... I emptied out the plastic waste box, washed it out and put it back in the machine. I got a good bit of it on my fingers. Now, 8 hours later, my fingertips seem to have a burning sensation. I'm a printer (on presses) for 30 years back. I've spent 80% of my life with stained hands from countless chemicals. It's just a part of my life. Never bothers me. Now my fingers are burning from a little powdered toner that means nothing compared to all that? Could it be so? Thank you.
