Likes: has anyone ever replaced the front door switch on a mp201? I have one that's not working giving SC320 code and I tried looking at how it comes out, looks like it isn't fun. Couldn't find it in the service manual.

SC 320 is a polygon mirror motor error. Replace the polygon mirror motor.
It also gives this code when no toner cartridge is installed
Make sure toner hopper and toner are installed.
If switch is bad, jump the connectors to make it think they are there.
Never understood why that switch was there.
Why do they call it common sense?
If it were common, wouldn't everyone have it?
it has toner bottle and toner supply unit it there. im sure its the switch cuz in service mode it will not change state like the right door switch. and I checked another 201 for front door switch to see if it changed and it did.
Check the point to point. The switch for the toner bottle insertion, laser safety switch, might be in series with the front door switch.Originally Posted by apump
ok. your thinking still laser?
I'm not sure what your reasoning is for it not being the laser motor
There is no documentation that I've seen to suggest anything other than that, or possibly the BICU
Replace the laser unit
the reason im saying door switch is because its not changing state when checked, so if you don't have 24v from it then laser will not fire up anyway. but I went ahead and ordered a laser this morning so we shall see. thanks
