Hello Valerio

There is no SC514 on an AP410N. Do you mean SC541? SC541 is a fuser code that a technician has to reset. It could be something as simple as a power spike, or it could be a dirty sensor or a blown board.

Clean the fuser thermistors.For reset enter in the service mode : press total clear (yellow)key-107-clear(red)key,touch SP mode,open the front door and turn OFF the power switch.Unplugged the machine,wait 10 sec.,plugged the cords,close the front door amd turn ON the power switch.

Please read documentation, here there is full information on fault http://files.mail.ru/X9K07N
SC546Fusing ready temperature malfunction
The Problem of the temperature of Fuse is serious and not always this faulty lamp of the heating or thermistor, in RICOH regulation of the temperature can be installed by SP mode, I recommend you to apply to service for skilled repair, this work must be executed prepared by personnel. Good luck you.

Fuser error.
Fix problem (Fuse, lamp, or thermistor), then reset code by entering service mode and powering off/on machine

It's a fuser error. Fuser may need replacing, and fuser codes can only be reset by a technician, to prevent further damage

hello sir; you need to reset, following the steps as below;
press "clear mode" then enter107 then press and hold down "clear/stop" key about 3 sec. or more, then turn power off and back on .
