Copier won't cycle after warm up.

service toner hopper

force toner by software

maybe toner finished. change toner cartridge

Remove the toner bottle carefully, pwr off and unplug the machine , then plug it in and turn it on do not put toner bottle into machine until asked for.

Toner is running low. Light come on to say the machine is adding toner. Soon it will come on and stay on.

let it run eventually the toner lite will come on, sharp copiers will run an extended period trying to add toner to the developer. developer is 70% iron filings and 30% toner as it uses the toner it cycles more in to stay at the proper level.

There really isn't enough information given to give a proper solution. This copier has the drum light come on steady or flashing to indicate the waste toner needs to be removed. I don't know if you're a technician or not but lay people have emptied the toner cartridge instead of removing the drum, removing the cap on top of the drum, emptying the waste toner , replacing the cap on the drum, then putting the drum back into the copier. I've never had a copier keep the drum light on after doing this.

Let me know if you need more help.

F26 Toner density adjustment problem. This means machine is undertoned. To repair, replace developer and enter "47" mode. Press 51. Press print. Allow the machine to cycle until it stops. Some feel that you should disconnect the toner motor first. This ??? ?????? happens probably because either machine wasn't set up properly, or the customer kept on using the machine with the toner light on.

occasionally on that model it will run continuously looking for toner when it has actually run out.....so check the toner, it does not always indicate toner required

Try turning your copier off & back on. Allow the machine to cycle after turning it back on - until it comes to ready or displays add toner signal again. You can try this three or four times as it sometimes takes the machine a few trys to advance the new toner to the toner sensor. If after 4 attempts you are still getting the add toner message - you may have a dirty or faulty toner sensor. The toner sensor is located inside the developing unit that you are loading toner into. Toner sensor is usually located on the bottom of the developing assembly & is held in by 2 scews. It can be cleaned with a dry cotton rag & reinstalled. 90% of the time power cycling the copier a few times will solve this problem.
