Question about Samsung SAMSUNG SCX6555N LASER COPY/PRINT/SCAN/NET SCX6555N Printer
Display screen shows imaging unit error #31-007 replace with a new one, have replaced imaging unit but hasn't resolved issue, have looked in the service manual but the error code is'nt in there?

I have encountered this problem twice on the same machine with different imaging units. I haven't received an answer from Samsung (presumably they will fix with a firmware update, their solution to everything) but the message and the red light can be cleared by powering down, reseating the the IU and powering back up. The good news is the user can still use the machine, even with the code.

Finaly got it.
Pull out the four toner cartridges and also the drum unit , staying in front of the printer , on the right side of the drum unit, you will find a small box with two contacts.
You need to solder a 63ma ( worked for me) fuse in paralel with two rezistors that it contains. It is hold by a small klipp - it is easy to get it out. You also need to empty the waste toner behind the opc , drum or watever you call it . Restart the printer after putting alltogether.
The second solution is to buy a new one but its price talk for itself - close to a new printer :-)

The imaging unit is that whole assembly that the toners are plugged into inside the front door of your machine. It a consumable unit available at many office supply stores. The instructions to replace the unit are packed inside the box with the new unit.

If this IS a CLP-510, first make an information confirmation print.
Press MENU, then press ENTER, and ENTER again.
Look at the counter for the imaging unit, is it a low count confirming that you have indeed replaced it ?
If not you will need to reset the counter.
Check the counters for the toner cartridges, and check the capacity of the cartridge. On a CLP-510 the image counter for the toner is held on the chip on the cartridge (which also identifies the capacity of the cartridge).
There have been some faulty (oiginal Samsung chips), and of course re-manufactured cartridge chips could fail (many re-manufacturers don' test their cartridges before dispatch, they don't have the facility to do so without starting the count on the chip (or 'bowing' the reset fuse on a CLP-500 cartridge). VERY few re-manufacturers can test these cartridges without starting the count.
Sometimes the 'replace xxxxx toner' messages are caused by toner on the three contacts on the side of the cartridge, or their mating contacts inside the printer. Rarely, this can be caused by a faulty circuit board.

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.
