Question about Sharp AR-164 Copier

Toner light flashing, won't copy

First i replaced the toner cartridge. i also changed the toner sensor in the developer unit. another technician, familiar with sharps said that it could possibly be the main motor which drives that section. i put it into maintenance mode, did the main motor test and it would not run. all other motors did. i ordered a new motor and replaced it: same problem. could it be the board that controls the motor(the main pcb, i believe).what do you think?

Re: toner light flashing, won't copy

Definately check and see if you are getting the motor current from the motor driver board and main pcb, before buying it. That should do the trick

How can i settle the problem of magenta developer finishing so fast. Magenter developer for Konica Minolta Bizhub C550 is getting finished so fast.

If the message Change Imaging Unit Magenta displayed refer to imaging unit with contents a developer.The Imaging unit life is 80.000 copies.
The imaging units located after front door when is located the waste toner box.
If the message M toner end/change the M toner displayed refer to toner cartridge
The toner cartridge life 15.000 copies 5% saturation.In full color mode the color saturation is 80% and the color toner life is 6.000-8.000 copies.
I think your problems is a toner not the developer.

Sharp Copier AR-M355N developer change is after 100,000 copies. We were at 95,000 copies and copies were becoming light and the developer done to 1/4. We were told somebody dump the developer because it...

The developer stays in the machine in the developer unit. It is SUPPOSE to stay in the unit and the level doesn't go up or down. It just looses some of its magnetic property therefore needs to be changed. I have NO idea about dumping developer, if so...SOMEONE doesn't know what they are doing.

My toshiba is showing that it's out of toner and won't copy. I've had a look and the toner cartridge is still pretty full so any help would be great!!!

hi when the copiers shows that need toner it is becouse there is no toner in the mix of developer, this is caused by a wrong toner in the machine, check that the toner is the one the machine use there are few copiers like lanier that seems to use the same cartridge but change the gear that turns the toner in the machine, move manually the gear in the cartridge by looking that the toner actually it is ok, activate the motor that moves the toner cartridge and check thatis is moving, also check the gears on the developing unit becouse if any of them dont move the toner never get the sensor of the developer unit and shows the signal of lack of toner

Light (faded) print

What's the copy count on the machine?  It could be resolved by adding developer to the unit.

The developer unit is inside the cartridge where the toner sits in. usually if you remove the toner hopper out of the copier and remove the top cover off you will see one compartment with toner and one with developer in it. The carrier is the the type of developer to use. All old developer needs to be removed from the machine as well as the mag roller in order to replace it.

Once it is removed the developer is placed evenly into the comparment. The hopper is reinstalled. Then a service mode is performed to calibrate the developed to make sure that the mixture is equal with the toner.

It should be done by a technician because if it isn't done properly, it will result in light copies being produced. The developer may get contaminated and have to be replace if it isn't done in the proper order.

The Unit where you've put the toner cartridge could be to far from the drum. Make sure your developer unit (unit where you've put the cartridge in) is locked in place.

Adding developer to sharp sf-2025

Hi, it means the developer requires changing. it has a life of 30k (i think). I would suggest that if your quality is not effected, then keep using the machine, or spend the money on an engineer to come out and replace it.

Cyan Toner always prints faded.

It is the developer. All colours should be changed at the same time. This can be accessed via the right hand side of the machine, when you remove the cover. (where the output tray is)
