I have two machines with a SC322 code (laser sync code)... We have replaced almost every board in the machine with no results. Any ideas?

Have you cleaned/replaced the laser sync board?
Usually this is a matter of toner piled on that board.

check for toner build up on the upper right cover switch i think they put out a bulliten for this one
Yes, this board has been replaced.

We have checked this switch, and it's operating correctly.

How often does this occur.
If it is erratic, I think I would replace the cover switch. You say it is acting normally, but those switches go bad on the inside and are very erratic at first.

The machine will code every time the print button is pushed. It will not make a copy. Clear the code, shut it down, and it codes agian as soon as the print key is pressed.

I should include that the orignal machine wa out in the field with a major toner spill. After the Tech (not me) vaccumed the machine out, it started the SC322 codes. It was then brought back to our shop, where other Techs (not me) shotguned MANY parts towards the orignal machine from a new machine. Apparently in the process, they manganed to "transfer" the SC322 to the brand new machine.

Jeepers, Ill bet your boss is thrilled!
Originally I was thinking that, in vacing the machine, someone had knocked out a chip on the board. And it still could be,.
But now I understand about two machines.
Here are a couple of things, Sw 3 on the IO board will disable SC generation. Run a copy, what happens?
I would start with one machine, and keeping the same NVRAM with the same machine is very important.
Initialize the laser at 400 and 600 before making a copy. The factory setting is on the BC.
Input that and init to it.
It may be the NVRAMS got mixed and this would be the result as both machines would have the wrong settings.

I doubt that the NVRAMS have been"misplaced", but ince I have not actually been invovled with the work, I can't gauarentee anything... YES, the Boss just loves this!!!

As I'm one of two that work on the high volume machines, I did not get a chance to check your suggestion, although I did tell the other Techs to try it. Apparently the original Techs invovled have "washed their hands" on the two machines, thus ME, trying to find more info on this problem, want to repair both, our customer's machine, and our BRAND NEW machine.

My Techs tried the laser adjustment to no avail. They also tried whatever the SP mode was to "reset the adjustments" (I don't have my manaul handy) and then try the laser adjustments agian, resulting in an SC329. I still have not tried exchanging the NVRAM, as I had to run several customer calls.

first try to cram your machine then do the laser adjustments before anything else.
then remove the laser unit and be sure the mirrors are clean for the sync detection.
then try replacing the LD unit.
if you still have the problem you should bring out your local ricoh rep.
i have seen the error show up when the print key is pressed and it was laser adjustment that corrected it.
remember dont trust anyone elses work try these checks and you should be fine

Finally... Progress!!! Today I was able to get both machines working. I started from square one, ignoring everyone else's work. Using a new lazer unit, both machines worked! One has been narrowed down to a bad LD unit, and I'm still checking the second machine, as we ran out of time today. Thanks for all the info and help!!!
