SOURCE: Invalid Imaging Unit and Toners
Sorry about my last post. I didn't realize that it would be placed unter solutions. BUT I did get a resolution from Samsung. They passed me to the advanced team and they suggested I use a special code they gave me to reset all the machine. As I said before the machine was giving me an error that all the toners and the imaging unit were invalid. Samsung said to try this and if it didn't work they would send me a new (refurb) unit. They said to press in sequence <menu><#><1><9><3><start (b&w)> then when the unit cycles it will ask to imput the country, in my case I entered the US. The machine will then reset itself and all the cartridges and imaging unit should be reset to work. IT WORKED!! The machine said to wait while it re-installs the toners. When it did the red warning light turned off and the printer is working great. Hope this helps.

No, what actually happens is the drum fills up with waste toner and you cannot empty it.

The Imaging unit needs to be replaced when the drum fills up with waste toner. That's what triggers the message.

If the drum units have been in storage too long they will bind up a little.
Lightly tap the drum unit on the ground. Look on the back of the drum unit and locate a white cam gear. Take a pair of pliers an rotate this gear until it moves more freely.

You will have to purchase an new imaging drum. It is the shiny green metallic cylinder in the bottom back of the printer. It is the last piece to come out when you remove the toner waste unit and then all the toners. It sits on the very bottom/back of the toner bay. They are not cheap but do not need to be replaced very often and it will give like new printing after.
The error message under that title is "Have the image transfer belt replaced soon." It's a new unit, but resists doing the Gradation Adjust. Tried returning the old belt (which was working before the replacement) and error message remains, so apparently the problem is not with the new belt.
System Error Clear (System 1 -> Initialization) gives "Result: OK" but has no effect; the problem remains after machine restart. However, it does NOT at any time give L-5 error (Transfer belt unit accumulated rotation time excess warning), just continues to say "replace image transfer belt unit", and will not allow anything else to proceed. What am I missing? (Transfer belt clutch malfunction?
