AP MESSAGE MESSAGE AP PUT IN NEW TONER

put a little toner(less than a tea spoon) on paper then pour it directly in the dev unit hole.switch off/on.did it work?

try to put direct toner in the developing unit then restart the machine if problem still persist try to replaced your developer

just check the toner cartridge maybe the toner is empty if its empty just replace a new one

ap means aging process or toner replenishment just check the toner if the toner cartridge is empty just fill a new toner

means copier is adding toner. you maybe able to install new toner and message will go away. also may be bad developer or sensor. replace the toner firsrt. if it does not fix it call a tech

hi

the AP means that the copier needs more than one cycle to add toner.
This usually happens when the copier is used for a whiile after the add toner message comes on

Hi 
The AP message indicates thet the dev is so low in toner that the machine has to go into a full cycle mode to get the toner levels up.
The error code is telling you that one cycle is not enough. you will have to turn the copier off/on and cycle it at least one more time....more if neccessary

AP means that the copier is going thru a major toner cycle.
Sometimes when you drag a lot of toner out for dark copies, the normal toner cycle is not enough.
The spring that takes the toner from the cartridge to the dev unit mat also be faulty or broken.
Sometimes the AP message will go away but make sure you have plenty of toner. 

AP = Ading Powder (toner) most of the times it means the toner is near it's end order a new one :)

AP = Adding Powder (toner) it's not an error
it's adding toner from the container into the developer unit while displaying AP. when there is enough toner in the container the AP will disappear and copies can be made when there is not enough toner in the container the toner empty light will come on.
