Question about Samsung CLP-300N Laser Printer

4 Answers

Samsung CLP-300N Laser Printer will not print, etc

The printer that is in a faculty office will not print now. The red status light is on continously. I checked for paper jam in printer. This printer was purchased from staple on Feb 12, 2008. I called Staples this morning and was told that I should call Samsung technical support. A new USB cable was bought at the same time as the printer . Please give any suggestions that will make this printer work again or what it be repalced under warranty and what is the process for replacement of printer.
Thanks, Diane Meyer,

    Paper jammed, red light on continuously, checked for paper jam outside tray and in back, nothing. Unplugged, restarted, everything, no change in status of printer.

    What's wrong?

    Same problem, red light is on continuously but there is no paper jam.  Sometimes if you open the doors as if to clear jammed paper and close them again, it will print.  Usually even that doesn't help.  Sometimes if you unplug it for maybe ten minutes it will print.  I wonder if it overheats easily.  This often happens after I've printed only a few pages.  It also can occur if the printer hasn't been used for a few days.

    hi, samsung clp300n all lights are on red and when i try to print it says on screen black toner low then says yellow toner low and so on all toners are full help!

    We have had this same problem from day #2 of the purchase of the printer.
    Calling Samsung repeatedly and on the phone for 30 minutes at a time on eight different occasions finally resolved the problem..however in the middle of printing a number of pages it stopped printing again. We are at a loss and based on the experience that we had with Samsung tech support, we are reluctant to call them. Their attitude seems to be that of the customer being stupid. We don't need that kind of customer support.

My friend has a Samsung CLP-300 and was unable to get it to work. The status light was on continuously. I rechecked all my connections changed the cable. As I had a CLP-510 that always had a problem with the waste container, I checked the waste toner container on this machine - it was full so I carefully cleaned it out with vaccum and then q-tips, put it back on the printer, then it same the blue ink was out changed that and presto the green status light came on!
Problem solved

Thanks to the Coast Guard!
I checked the waste toner cartridge, which didn't have very much toner in it.. but decided to dump it anyway. Word to the wise.. DON'T, if you don't NEED to. Afterwards, toner had coated EVERYTHING in there, and I used a lot of qtips cleaning up what hadn't been dirty before. So, use common sense.

Second, another forum had a copier repairman who offered tips, which I echo here.. They helped me, maybe they will help you as well.

It seems there is a COMMON problem with the rubber 'foot' that grabs the paper. It loses it's "tackiness"... An old HP Deskjet 560c I had did the same thing (although after a SIGNIFICANT number of copies). Anyway, some recommendations were to 'revive' it using water. He suggested alcohol (which I used). I scrubbed it all over the paper-facing, curved surface. (Turn power off, remove toner cartridges, remove imager assembly--out the front, remove paper tray, UNPLUG!, Turn onto it's "front/face". You'll see it. It's a little rubber 'tongue' that 'licks' the paper up, and feeds it into the rest of the printer. It needs to be cleaned (I guess ultimately paper 'dust' particles clog it up, or it dries out). This helped me a lot. I scrubbed it with alcohol, scratched it with fingernails/emoryboard.. rough it up a little.
I also cleaned the little grey rubber/plastic rollers in the back of the unit(behind the rear door). I don't know if it did anything or not, but I had everything out...and I'm trying to be complete.

The final piece that helped, pay attention to the paper you open.
This sounds a little offbeat, but I remember this from the original days of laserprinters and copiers. This is from the copier guy. And it worked for me.
Often, copier paper has an 'up-arrow', that indicates which side is for the primary image. The paper has a 'grain'.. One way will make it easier to pick up, the 'rough' side. The other side will be 'slicker', and harder for the machine rollers to grab.
SO, I ruffled the sheaf (fanned it out), marked the edge that matched the arrow on the **** when I opened it... or the 'up' way the label was printed if there's NOT an arrow. Try it several times each way.
The four options are :
1) face up, label edge deepest into the printer
2) face up, label edge closest to the outside of the paper tray.
3) face down, label edge deepest into the printer
4) face down, label edge closest to the outside of the paper tray.

For me, having the 'image/up'-side placed into the tray facedown, and the side that had the ****'s label fartherest into the printer (option#3) ...well, it gave me great results.

I hadn't been able to print 2 sheets in a row for quite a while. So , I printed about 10 images, and will pick up testing tomorrow.

Good luck to you.. I like the images it produces.. unfortunate it is just soo unreliable in its feed mechanism.. Apart from that , I love this printer.. .but because of that, I want to run over the thing with something heavy.

We just had a similar problem in my office. Our Captain's printer was giving a solid red light. After replacing all four toner cartridges and disassembling it to look for paper jams, dirty contacts or dirty paper jam sensors I looked at the manual. I noticed something about the waster toner cartridge, which was a problem on another printer that I had fixed before, but I hadn't thought of that option yet. I yanked the waste toner cartridge, which is to the left side of the toner cartridges when looking from the front. It was full.

At this point you have two options: get a new one or clean the old one. Being thrifty and wanting to fix it immediately, I dumped all the old toner out and used long q-tips with alcohol wipes on the end to clean out the sensor windows which the printer uses to sense if it is full or not. THESE NEED TO BE PRISTINE! There is a very thin piece of plastic, that I suspect is an LED light filter, that will also need to be cleaned. This is also inside the waste toner cartridge.

This may or may not be your error, but this fixed it for me.

Printer status light glowing

Chances are that you have the same problem as found here. I am guessing that the toner waste container needs to be emptied (you can do it your self) and/or the sensor is acting up.
