Chosen Solution

I’ve been using my Samsung SCX 340 printer for a year and half and last week, it stopped printing. I got this error message : “Not Compatible Toner cartridge” whereas I had been using the toner cartridge for a while already but it wasn’t empty. Do you know what could have gone wrong? Many thanks, Estelle

Hi, Try this: Power off the printer. Remove the power cable for more then 10-15 min. Remove the cartridge. Check it well. You must have a small board with golden pins on it (usually 4 pins). From this place the printer communicate with the cartridge (in the cartridge you have a small board with a memory i.c). If this not help you’ll need a specialist. The problem can be in the printer and/or in the cartridge (more probably in the cartridge). Regards.

Hi guys! I had the same problem with my Samsung CLX-3185 but I finally FOUND THE SOLUTION!! Someone mentioned that it might have had to do with the receptors (the four golden pins) on the toner cartridge, and I thought that might have been the case since all four of my other cartridges were working just fine but the cyan one just kept coming back with that error message. This is what I did. I simply took the cartridge out, used my shirt to clean the golden pin areas as well as my fingers. Gave it a good rub, and then shook it a little put and put it back in. Then it instantly started printing again and the error message was gone! Side note: my toner cartridge was a refillable one, and not one from Samsung as well. This worked wonders for me and finally resolved my problem!! It was that simple. Hope this helps everyone else :)

BOYCOTT SAMSUNG. They sell you a product that works with various cartridges and then break your printer when you do.

I had the same problem. Turned off power and disconnected pwr source. Replaced all toners with new (not original), waited 15 minutes, turned on again and it all worked .

I have the exact problem, my ML 1675 V 3.11.34.00:08v (I presume thats the driver) I added paper and it didn’t start again. I have the correct cartridge as it worked a minute b/4 I added paper. Tried all these things no go, called Samsung support they were very helpful… tried the same things as I had prior to the call still no go.. bottom line was I was advised to go to their website and BUY a new printer. I thought that was nice, I know this one wasn’t expensive (a cheap-o) but it served my purpose and with only approx 250 sheets used I am a little peeved off. Don’t have it repaired unless it was very expensive. dumped it.. go buy another brand..

I had the same thing happen with my Canon PC940 copier. One day, copies were great, the next time I used it, they looked like the toner had run out. I live in an area of high humidity so I suspected that the toner may have clumped together. I put the cartridge in the oven at 150-175 degrees for two hours and, voila, everything began working again.

I have the same model of printer but I have never had such problems…. Have you ever replaced the toner? Are you sure that you bought the right model or was it qualitative enough? It is very important! I have seen here hardware.be/printkop/brother a lot of toners for almost all printer models but I have never tried it. Although the reviews of this shop are positive. Have you ever tried it?

Firmware for the printer was probably upgraded along with your drivers. All the new drivers make anything but Samsung toner incompatible. If you have the original installation disk, delete the drivers you are currently using. Use your original installation CD ROM and reinstall the original drivers.

I have the Samsung M2875FW. It takes cartridge #D116L. I had the “toner not compatible” message on the printer and it would not print. What I did was unscrewed the plastic piece containing the little circuit board with the four contacts. This plastic piece covers the entire rear face of the toner cartridge. Once you remove the two screws, it easily unclips. I then replaced the plastic assembly from the defective cartridge with the one from my working cartridge that I was replacing. Be careful while doing this not to mar the black roller on the front of the cartridge. After doing the above procedure, the cartridge was recognized and printed perfectly.

We bought a toner about 5 weeks ago. The two red lights are coming on and we can’t print. Some ink is coming out.please advise

Try going onto the Samsung window and search for more printers. The Samsung always keeps changing it’s compatible code, which is very annoying. The code should be something like 192.168.1.20. I had that compatibility problem myself. The 192.168.1.68 wouldn’t work, so I used the 192.168.1.70. When that wouldn’t work, I used 192.168.1.72, then I used 192.168.1.66. Finally, when THAT wouldn’t work, I used 192.168.1.73, but that is subject to change. Hope this helps.

Vincent, hi what you have to do you have to put another cartridge and see if it will tell you not compatible again . The course of not compatible it can be (MICRO-CHIP on the cartridge or firmware updated).

Unforunetely the only thing I could do to fix it is use theirs now. Sadly, I think their may have been an update on the software and it recognizes the generic one. Their ink does look nicer but it does stink how much more it cost.

I have 2 x samsung Xpress M2020w , one will use the toner I have the other says its not compatible with the same toner? thanks

The printer that is refusing to accept it is at a higher Samsung software revision level than the printer that accepts it. Because Samsung apparently under took this intentionally, I acquired a Xerox printer to be my longer term solution. I will use the Samsung printer only until the toner that I now have, runs out. I had to throw away A couple $100 worth of toner because of this software upgrade.

My solution once I finish using the existing genuine Samsung toner cartridges that I was forced to purchase at an outrageous price, is to junk the Samsung and, since HP is the owner of Samsung at this point, I will absolutely ignore any HP offering and instead will purchase a Xerox or Canon as a replacement laser printer.
