SOURCE: Density sensor out of range

The density sensor is located in what is called the Colour Registration Detection Assy. When you open the front door where the ETB belt is, the assembly sits were the door closes at the top on the printer side.

It can get toner on it, so check it and give it a clean. But do not touch it with your fingers.

I have found this explanation of the error message:-
Description: Software performance error
The software attempted to perform an unexpected operation
.
Causes: • Software defective • Internal parameter incorrect • Insufficient working memory • When this SC occurs, the file name, address, and data will be stored in NVRAM. This information can be checked by using SP7-403. Note the above data and the situation in which this SC occurs. Then report the data and conditions to your technical control center.
This can be confirmed here:

Color not registering


Try going into the diagnostics of the printer.
Either in the menu, or network connection.

Try running a clean process if this has one.
How long had your toner run out for.
Try pulling all toners out, then see if you can pull out the spool drum (printing drum)
check that they are all clear.
Are you using original toners, or remanufactured ?

Also check if you have an excess toner cup.
This may be full and require either emptying or replacing.

Ricoh 3310l fax shows error code 0390H in display. Anyone know what this means?


I've never seen a message like that with the 0390H code. There is no mention of that code in either the user manual or service manual. The closest thing is the sc390 code, which means either the toner density sensor or the developer has gone bad, and typically replacing the PCU can fix that problem.

If the new PCU doesn't fix the problem, you might want to try calling Ricoh for support, since their documentation doesn't mention that code.

ERR (990) or ERR (999) are both error messages which are displayed when a sensor does not work normally due to dirtiness. For example, either may be caused by a dirty maintenance unit or clogged ink nozzles. It may be possible to resolve the issue by cleaning the device
