sc 329 is the laser unit problem. the noise is not gear, it is laser noise. you have to replace the laser unit mate. thats the only solution.

Thraser, your still battling this machine? Of course your readings will be off if you only have developer coverage over half the mag roller? That's where I would start.
I also now wonder about your model #, because I don't think that the 450 has a VSDP reading, but the newer ones do. It refers to the "immediate post-pattern output" of the ID sensor -not surprised that these readings would be whacked!

There are two service codes that you need to run 2801 and 2805 after you put the developer in the machine.

Press the yellow button on the copier. press 107 on the keyboard. Press and hold the clear button. Then run the service codes.

You have to run the codes first after changing the developer. You might have to replace the developer again to get the correct mixture.

1st laser synchronization error.  This should be looked at by a Ricoh technician to see what needs to be replaced.

You have to have all the firmware in order to able to do that. It comes on a PCMCIA card that you plug into the copier. If you format the hard drive, there will be no way of getting the programs back unless you have that card.

There tough to get but I found a few of the cards on EBAY. Once you get that, then it's a matter of getting a hold of the software (if it isn't on the card already).

The manual is in PDF format, however on the same page is a link to download the free acrobat reader if you don't have it so you can read this manual.

Please rate this solution and thank you for using Fix Ya!

You need a manual to calibrate the scanner do you have one?

There are some holes in the scanner that need to be calibrated with a tiny screwdriver. The manual teslls you the correct settings.

Did yiou remove the cable?

When developer goes bad you use more toner for one thing, but the main sign is a gray background in your copy. The print should be black but appears to be gray. The ricoh 350/450 was always noted to leak toner and developer as it runs. Check your machine and see if you see any small piles of toner, which also has developer in it, in the machine. Ther are small seals made of felt that need to be replaced if you have this problem. These seals rub against the drum sides....Good luck.

The fuser probably will not help. I think you probably will need a PCU, and a service call.
