Ricoh Pro c5200 DEMS Failed

[nysamara]

Hi all! I have a new Ricoh C5200, machine was purchased unassembled. I installed everything following the Service Manual but when I tried to do the DEMS it fails. Any clues?

Bet it was not new. Are you trained on this Production machine. Pay a trained technician to get it working for you.

The Pro C5200 was introduced at least 5 years ago and was discontinued and replaced by the Pro C5300 in the first half of 2020. You either got a re-boxed machine or one that has spent years setting in someones warehouse or garage. If it has been setting in storage by now you will need to most likely ALL the developers especially if it has spent any time setting at an ambient temperature of less than 65 degrees F. You may even need to replace the development units if the old developers are clumped to the point where you cannot fully remove them from the units. DEMS will not run properly with crap developer..

Do you have any other issues other than DEMS failing ?

If you run full MUSIC does that pass OK?

Run around colour 50 duplex pages & check the print quality, do all the colours look perfect ?

That may be the issue, it was stored in a not controlled room for a while.

I tried Full Music and it also Failed. However prints look good.

I was able to identify that the issue is only with the Yellow and the Magenta. I was thinking that it may be an issue with the laser unit. I swapped the drum unit Y with the C and it perfectly printed the page. Is there any troubleshooting guide for the laser unit? or any suggestion?

Run a few hundred 11x17 with a lot of print on them. Then run toner refresh or forced toner add. Then try DEMS again.

If you post the examples we could give you suggestions on what it might be. I wouldn't start with lasers based on the age and what you have said about where it was stored. It would start with DV and DV units personally

I already changed DV. If I move the Yellow or Magenta PDCUs to the Cyan Location those PDCUs printing results are very good. However the Cyan which initially was printing good start failing in the Yellow or Magenta location. I attached a picture of the Test Page, if I do a full print of yellow and magenta I get a a very light color.

I was able to resolve issue... It was the laser power supply cable that was disconnected. Apparently that happened during transportation.

That was a good find, you suspected the laser when you first had this issue. However it can't have been the 'laser power supply cable' I would have expected at error code.
