you said you change the laser? maybe the laser you change is also deffective?"A4200" is polygon motor problem try another LSU or laser i think thats the problem

Do you hear a loud whining noise, aside from the customer at this point? (Rimshot). That's the main indication that the Laser Unit is bad. But normally you'll get just a 4000 code. Try a different Main Charger. Arcing can do some crazy things.

Don't you mean error C4200?

On Kyocera Mita machines the codes are grouped by type, so that all "4000" series codes are related to the laser, all "6000" series codes relating to the fuser, etc.

The terms are not precise, but the advice is still good . =^..^=
