km/cs 1620 lsu code reset

[Sathsayin]

first time working on a km/cs 1620 theres no 906? or equal i have c4000 code lsu/polygon motor. i unplugged and let sit for awhile then repluged back in and it comes up with 1 (copy output count) i hit start and then im hit wiht c4000. i never hear the lsu spin up ive reconnected all the connectors on the engine board. after troubleshooting im almost possible the lsu is gone. but i want to make sure there isnt simulation im missing. it happend towrad the end of the day and i dint have time to look in the manual. anybody know of any other ways to clear a code on a 1620 beside opening and closing the front door and unplugging/turn off and on. (i also ran the fuser simulation to no avail hopeing it might clear the code). maybe i am clearing it by turning it off and on and the lsu is gone. Ok to get to the point since ive wrote a whole freaking paragraph on something that shoud've take one line but hear goes. Does 906 clear anything that turning off and unplugging and turning back on wouldn't. Since this model doesnt have 906 have i done all i could've

(p.s ive got a spare lsu thats whistles but the polygon motor isnt completely unstable yet so im gonna use for testing porposes tommorow!)

i'd say your laser is busted. when you switch off/on it resets but the condition still exists that caused you fault so the code comes up again.

i just checked my manual and they have removed u906 and i never noticed. from my experience U906 exists to reset an isolated unit like the large capacity trays on the 2530's etc, so maybe on such a small machine they thought it unnecessary?

Unless something is unplugged you need a new laser unit. Let us know what happens after you swap it out with the noisy one

If it's like to KM-1650-2050 the laser is replaced on TB#66 for full part price credit.
