I have not gone to this copier yet, but the other tech has replaced the laser unit & engine PWB? He said it gives him a black copy then codes out. The copier worked for a day or 2 after replacing each part, but the code is back again. Any thoughts??? We have little experience on this model.

I guess that you already know that the C4200 is a beam detect error, and the manual suggests changing the laser and engine PWB in that order.
Just to be thorough, I would mark the parts ('original' vs. 'new'), then try every combination. I have not had a reason to pull the laser from a Falcon III. Does it have a laser shutter, and if so, does it move properly? If you make no progress there, it's time to pin out the harness, and to make sure that the laser harness does not get in close proximity with high voltage lines (induced currents). Also re-seat all connectors related to the laser and/or engine PWB. Let us know how it goes. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

You may want to try and replace the drum and M/C. Arching has caused this problem on falcon II's.My mission here on Earth is to help all you Dum-Dums!Comment

maYBE Is in LSU its in polygon motor try to diagnoseERROR HELP ME AND HELP YOUComment

First Tell me, is a new or used laser
Tell me, is whether the code seems to be full screen or will he be in the corner
That appeared on the entire screen should be replaced by a laser
That it shows up on the corner, it means that you must clean the laser.Dont measure yourself what has been done untill now , but must be compared What You Can Achive with Your AbilityComment

Got a KM5050, machine was FILTHY, dust,dirt everywhere. tried to phone fix the 4200 code, no good. Arrived and turned machine on= ok.
but after scrubbing and runnning @500 prints/faxes and copies, the EC 4200 returned
I reseated "Y8" connector, I swapped out LSU but the code returns during pre drive.
Simm mode U906 didn't help.
guess I will go with the PWB burried behind the network gear monday morning.... Also, I will have to check for flash updates.AN ounce of prevention is worth a pound of obscure

interesting PDF madas. The KM5050 has no ferrite core attached to the wire bundle going to YC8

I have NEVER seen an LSU go bad on a Falcon. C-4200 is generally an arced Main Charge. Don't bother cleaning it, just replace it. You can even use a Falcon 1/2 MC. That has always resolved that issue for me. If an LSU is actually bad, you will know it. If you have worked on any 1810 or 2050, you (and the entire city block) will know this.Comment
