Re: I got a Error code 9-343
Any 9 -xxx code is related to the xerographic area of the machine NOT the fuser area- you don't mention the model number so I can't be specific, but try the Drum/CRU/toner area, make sure you haven't dislodged anything (modules, plugs, sockets etc.)

Hello! This code is related to a Fusing temperature error. You probably need to change Hot roller (or fusing roller), Pressure Roller and both thermistors. You can reset this code but it will pop-up again sooner or later. The best advise i can give you is to call a technician (if you do not have technical knowledge) If you still want to reset the code try this: Press yellow key Press in the key pad 107 Press red key at least 5 sec. Press "copy SP" On the key pas press 5810 and #. On the touch panel press "execute" Exit all the way out. Turn the machine off and on.
