How to reset drum counter on panasonic workio 150

SOURCE: drum reset for Panasonic kx-mb781

There is a little special (white) gear on the outer left side of the drumkit - a little bit below where the toner sits. That gear joins with toner mixing assy - and you can rotate it in counterclockwise all the way back. This should reset the drum counter - worked for me - I hope it also does the trick for you ;-)

I think this machine does not have a reset option instead you can reset manually.All you have to do is on the right side of drum unit there exist a white + type notch,rotate it clockwise till it allows.Put back drum unit into machine.Switch on and see replace drum and supplies message will disappear.In my case it worked.Hope this is the best solution.All the best

the best solution to that problem is that there's a dirt on the shafting of the polygon motor, try applying some lubricant to make the polygon motor go smooth.

The drum density sensor is covered in toner and needs to be cleaned. this is a job for a trained engineer.
