Toner alarm stays on with new cartridge

Yes, it could be a sensor. Remove the toner and drum assys as well as the paper cassette and look for the sensor actuators. Usually black plastic pieces that will move a bit. Blow them out with air and see if that doesn't help. Let me know.

Open up front op panel,mid door opens up tube sitting on top of drum unit is the toner cart! be care full can get messy!Pull lever on end of tube (will only go 1 way from original position)lift up and dispose of.pull white tape off of new cart install in drum push lever,open and close mid door a couple of times to cycle toner toner message will disappear.

Either drum defective, not sitting in correctly,or toner has dumped in unit covering drum contacts!

would replace drum and toner! clean inside as best as possible all contacts! make sure you have the correct toner drum for unit.

clean the LED array with a soft cloth or tissue or the alcohol wipe that comes with new toner cartridges if you still have it. open the cover to expose the drum on the bottom side of cover is a black bar(LED ARRAY) as wide as the drum but about a half inch thick wipe the bottom side that will face the drum when the cover is closed

rwhen you replace the toner youare putting it in the drum cartridge.the whole black unit gets replaced.lift it up to remove.when you replace it also install a new toner cartridge the drum resevoir will be empty when
new it will need a new toner cart. to fill it now you need to reset the drum counter.push select function
button,to the right number 8 or 9 says counter display
push it,screen will will say drum count reset? push yes arrow screen will say are you sure? push yes
tada! if it now says replace toner open the white cover
over the drum then reclose it a motor will run for about 30 seconds its adding the new toner to the
resevoir you may need to do this about 3 times or until add toner message goes away

may the cartridge dameg ore toner sensor proplem

You need to clean the drum surface as well the charger roller. Removing the paper jammed can caused the surface get the dirty by toner split.

There is no reset code the likely thing is that you have a faulty toner cartridge. Put another new one in and check the machine then.

Before you try the above shake the toner cartridge and tap it some more as it may also be the toner inside have become solid and needs breaking up.


Hope one of the above works for you

Hi there you might have a faulty toner cartridge is it a original or has it been refilled? I suggest to install a new toner cartridge and hopefully that will cure the fault. If this dosen't there maybe a small piece of paper stuck in the cartridge or after the toner cartridge within the heat section open the back of the machine (the jam door) and check there is no paper.

If the printed document is getting stuck just after the toner cartridge it will most likely to be the heat section will need replacing.

Hope this helps you and please rate me
Thanks J
