Hi,
seems like a silly question, and i dont know about canon copiers, but on my toshiba, underneath the key panel there is a scroll button that turns the brightness of the lcd up and down, if hit by accident, as often happens the lcd appears black. It has tricked me before!! haha
Take care

Canon ir8500 E000019


That means the toner waste bottle is full. Located behind the panel on the right side of machine close to the rear. About 12 '' high or so. Turn off machine. Remove the two screws that hold the panel and remove the panel. Pull out the The plastic container you see which has toner inside which is no good and is waste. Empty it in a secure garbage bag etc so it doesn't get all over the place. Then replace the the container, making sure it is securely in place as it was before you started. Refit the panel and the two screws. Then Turn machine on.

Hi. Canon says this

If paper has jammed in the machine, clear the jam, reload the paper in the machine correctly and then press the Black or Color button.

There is another step to fix this, also from canon.

CANON iR C2105!! no display on the LCD!


try adjusting the contrast, open front door and look under the panel there should be an adjustment screw for the contrast, if it doesnt work I suspect it is the panel itself that is bad.
