How do I correct 'invalid imaging unit' error?

This error indicates to an invalid image format. However, why this is happening and what the error code usually means ?
Actually this could be appear when you are trying to run a program that is made for or intended to work with a 64 bit Windows operating system, but your computer is running on 32 bit Operating system.

You need to get the correct version of Kon boot.

there is a chip on the new drum that is bad. you need to return it to whom ever you bought it and they should replace it.

This is problem with graphing differential equation. Invalid Axes error occurs if Axes=TIME or if t(time) is set as a CUSTOM axis. This is important to noticed: if Fields=DIRFLD you cannot plot a time axis. See captured image

Try a factory reset by pressing menu->ID Copy->Left->Right->Menu->Black Start consecutively. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.7px Helvetica}

After 2 years ,surly it need to change some part because of life time of some part that is very tired ,try to show it or take it to samsung service center in your country ,...

Check/clean the 2nd disc if any finger print on it. or clean the laser unit for CD drive if you can and have correct clean liquid in your hand.

Or do Low-Level format your HDD before doing recovery.

If you still can't keep doing recovery after you have done all three steps above, there are some thing else wrong with your motherboard.

sounds like your printer engine is starting to take a long unhappy downturn..

I had this problem with my CLP-550, which is now 5 years old and is still on the starter toner cartridges. I found a solution at the following URL, where I at least found a picture of the imaging unit:

It must have been a contact problem on my imaging unit, because all I did was remove the unit and put it back.
You need to open the toner casing and the duplex unit. Then open the top housing, exposing the imaging unit. Open the plastic retaining levers at front and back of the imaging unit, and just lift it out (not too far), and then put it back.
I then closed the whole thing and it again worked perfectly.
Hope this helps someone.

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.
