I have a samsung clx 3305 fw , i did the procedure to reset counter of imaging unit (...#1934....etc ) , but the counter didn't reset ( the other counter did )....where i was wrong?

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.

Well it is a tricky operation, because you have to put some screws off the back of the printer and make a short circuit. The safest way to do this is to take to a professional workshop.
