Re: 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.

Re: Invalid Imaging Unit and Toners

My Samsung CLX3160FN was working flawlessly till a surge hit it. The network connection stopped working. But everything else worked fine, it copied beautifully, faxed great, scanned like a champ, just did not do it over the network any more. Samsung was real fast about sending me a new main board and a technician to my house. Now nothing works. It is giving a red warning and says all the toners and the imaging unit are invalid. The technician couldn't figure out what was wrong. He said he would order me a new printer. I just hope I get a new one and not a refurbished one. Mine worked great and I hate to get a problem unit from someone else. The technician said he believes that the new card has a bios problem in it and was not properly programned for my printer.

My Samsung Color laser printer indicates all four color toners as 'invalid' despite changing them. It also indicates the imaging unit is invalid. It was bought new and functioned without any problems for...

When you changed the toner did you change the chip for them? you need a special chip for each and evry one of them. I had that problem with my CLX-2160 and i fixed it this way.

Poor quality black output

There is a defect in the Imaging Unit of these printers....if you replace the imaging unit, the problem of the faded black prints go away. If you have less than 7000 prints, you can call Samsung for a warrantied replacement. The Imaging Unit is supposed to last at least 20,000 prints.

Deteriorating image quality

Good Evening Robert,

The setting for non dell toner only controls the fuser temperature, and will not cause you any print quality issues. Toner is actually made up of ink and plastic. The fuser melts the plastic to "fuse" the image to the paper. Dell toner is set to "fuse" at a specific temperature. when you use non Dell toners, the temperature required to fuse may be different, and when set to non dell toner setting, the fuser temperature is raised to the maximum to ensure the other toner fuses properly. The down side to this is that you will wear out the fuser sooner then it should.

As far as the print quality issue you are having, it is most likey caused by the imaging drum.

Regardless of the estimated life for the imaging drum as stated by the printer, this is just an estimate. Many things can and will cause the imaging drum need replacing. ( Just yesterday I replaced a black toner in a 3115 that was less then a month old... genuine Dell... with more then 75% expected usage left because it was defective).

On this printer, each of the 3 colors and the black are all independent of each other with the exception of the imaging drum. Even within the imaging drum, cyan and black are independent of magenta and yellow on the first stage of transfer. When you have deteriorated print quality that effects more then one color, the first step is to replace the imaging drum.

The Primary transfer, secondary transfer, and tertiary transfer of the image are ALL contained within the imaging drum.

The chances of having 3 or 4 bad Developers is very very slim. If your print quality issue was related to only ONE color, then I would say you had a bad developer unit ( the 4 items located behind the imaging drum when removed). These are far more difficult and expensive to change.

The BTR ( bios transfer roller ) is the only other item that "could" effect your print quality, however, based on the symptoms you discribed, I doubt it. Besides, if i am not mistaken, the imaging drum kit comes with a new btr anyway.

Although I am sure you may be disappointed with the fact the drum unit is failing while showing it still has life remaining, the solution to replace it should restore your unit to full operation. The unit is light sensative, and effected by physical age as well as the number of prints it has supplied.

Please evaluate the solution i have provided and, rate the solution appropriately to show your support.

Pages full of toner / toner streaking

First off, this is a comment from a random person who may or may not know ALOT about these printers and toner/printer design in general. All toners are not designed to the same specification. Toner is a combination of plastic "pigment" and iron like shavings to make it magentically attracted to the electrical charges within the unit. Different toners conform to different grades and mainly size of the particles within the blend. The manufacturer doesnt only recommend that you use their toner to make them money, yes of course it makes money, but its because when the unit is designed it is designed to use a certain grade of toner, trust me if you put the non-branded toner vs the branded toner under a microscope you would see quite a difference. Often the non-branded toner is much larger in particle size (obviousely because its cheaper to make at this spec). This causes a variety of issues from excess toner not being cleaned off of developer rollers, IDT rollers, or clogging of toner dispenser tubes in the unit and the micro filters contained at the toner dispenser assy and developer assys. Also as for the issue not changing when switching to dell branded toner - the dispenser tubes within this unit contain up to 500-1000 pages worth of toner, making no change in toner you make immediately visible. Also depending on the damage caused by the previous toner, it may not be able to be fixed until all the components in between the toner and final delivery (drum cart) are replaced. In this case more than likely the toner dispenser assy, all developer assy's, and drum cartridge need to be replaced, and than be sure to stick with factory branded toner :)
