Fix an error message on the Ricoh Aficio 1224c that says 'used toner bottle full'? We have emptied the used toner bottle but the error message persists. What is the best way to fix this?

Check the waste bottle to see if there is a chip mounted on it somewhere. If not see if there is an optical sensor or clear window. If there is a chip it will need to be replaced or a new unit used. If there is a window or optical sensor you should be able to remove it, clean it out, and replace it. These are often the last part to fill with toner and create a light path block.

I am getting a 50.7 fuser error on our hp 4500 laser printer. we tried pulling it out and putting it back in etc. we read that it may have something to do with the optical eyes underneath it? we are afraid...

Denotes a fault with the fuser drive motor or the fuser motion detection sensor (do not change the fuser)

Remove the fuser and check that it rotates freely.

This error can also be caused by a jammed fuser. Remove the cause of the jam if possible, if not replace the fuser.

System resetup procedures for canon iR2016

hi you error code is referring to the fixing film in your fuser unit is not aligned, in other words its moved to one side and the sensor is detecting it as not aligned. order a new fixing film and replace it or order new fixing unit.

Sometimes just a reset will fix, other times it is a problem in optic drive or sensors

to reset enter buttons clr, exposure, clr, exposure, (must be done quickly) the display will blank, enter 14, press prnt button, then clr several times to get out and thats it.

Panasonic FP-7735 Error Code E3 40 Help!!!!

E3-40 is a toner density sensor error. It's probably toner getting built up on the sensor. It's located under the drum. It will look like 2 little LED looking things on a little circuit board about 3-4 inches long and half an inch wide. You can blow it out with canned air.
If that doesn't work, then the sensor needs to be replaced.
