A+ video! For anyone with trouble removing the wire clip: I had to use pliers to firmly pull out the wire connector. It was too tight to remove with fingers. No damages.
Thank you very much! I don't use my printer often, but for the last few years, it's been printing dirty. I followed your steps here, and it's printing like new!
Geat video and explanation thanks. I had a transfer belt fault on a CLX-3305. Completly taking apart as per your second half of video and cleaning has solved the problem👍 the only different thing I did was fitting the side springs before the outer cover was reftted. Acess to them was then easier.
Excellent informative clear instructions. My printer had been fine until I needed to replace the black toner with a new one and the next print was awful quality with faded strips. Followed your instructions and felt very comfortable with my execution of the process but unfortunately made no difference to the faded bits. Could it be my new black toner cartridge?
Hi, this video has been most helpful. Upon cleaning the transfer belt, it has started to make very loud screeching noises when calibrating and printing. What can I do to solve this issue?
CLP-315 with transfer belt not being wiped. I did clean it and disasembled just like in the video. The wiper has two rubber parts that do the wiping. The bigger one came loose when I tried cleaning it properly however. I cannot find a replacement part. Do I need a whole unit or will just the wiper fix my issues? It seems like the wiper does not take off all the powder left on the belt for some reason.
Thanks for the clip, very helpful, I replaced the transfer belt with a new one (Samsung) however the Status light continued to flash any ideas? Thanks again
This procedure will require going into the Tech menu to reset the counter for Transfer Belt (there are other CZcams videos on how to do this depending on the model, but it essentially a specific sequence of key presses on the controls: the display will read Tech menu if you are successful. For the printer in this video without keypad, the sequence is Menu, Back, Left, Right, OK, Stop/Clear, Menu. The C460 with a keypad uses Menu, #, 1,9,3,4, Menu. Once in Tech Menu, then go to Data Setup, then Clear Count (for the specific part you have replaced)). The mainboard doesn't "know" that the Transfer Belt (or any other consumable part) has been changed: resetting the counter is the only way to tell it you have completed the procedure. If you get error messages on any of these other "Consumables" and/or the Status light continues red/message appears you need to reset any of these parts, the Tech Menu is the only way to do this after you change out the part. Important: only change out parts once you have pulled the plug. Hot-swapping parts with the unit powered on may create problems with locking in error messages and may damage the mainboard processor.
hello, good afternoon, my printer marks the entire sheet with a very dark background, they told me that the problem could be the tape, if the tape is cleaned with alcohol and the blade, I will solve the problem or I have to buy the complete new tape, thanks .
Hi great video. I have the same printer. I bought black toner but it is not original - they promissed it would be just as good as the original. Now I am not sure why the black color is weak when I print. Would it help to maintain the printer (maybe I did something wrong when I mounted the black cartridge) or is the problem that the toner is not original. It would be nice to know before I start maintainance. Thank you in advace. Hope the spelling is ok.
I think there is nothing wrong mounting the cartridge. Probably the toner cartridge is defective but the problem could be the drum unit too. The compatible cartridge are often good quality
Great Video!! Thanks a lot - I just exchanged the transfer belt! My printer now is printing again :-) However - the note on the little display "prepare for ne transfer belt" is still there. How can I "delete" or stop this message ...
I figured it out - I missed replacing the screw that holds the black flat plastic part at the end near the wires. After installing the screw (which I now call the colour screw) the printer works perfectly - no more ghost images and bright colours. Thanks again for the video it was excellent!
hello, thanks for these, great videos! I have a question, I have a samsung 3305FN printer and it gives 2 errors: "replace ITB" and "replace fuser unit". I know there is a chip resetting method for drum unit by soldering in drum chip but I want to learn if there is a way to reset "ITB=image transfer belt" or "fuser unit" with some chip soldering or anything like that??
i can't get the transfer unit to stick back up in its original position, which makes it impossible for me to put the waste cartridge back. you make it look so easy. any suggestions?
It improved quality a bit. But still there are two horizontal stripes that go across half the page, sometimes black, sometimes multicolored, which also interrupt the printing, and I don't know what it could be. Can anyone help?"
i cleaned the transfer belt already, but does not seems like that this was it. What do you mean by charge roller? Does it make any sense to try cleaning the drum? @@viandant5
I just replace the drum unit, a new cartridges toner, and the lights still blinking, all of them. I was wondering if you could get some solution to this problem. Thank you
There are no reset procedures. I think the problem are the chip. Are compatible cartridges? However Samsung make all they can to create problems to cartridges, even original ones
@@viandant5 the cartridges are compatible but not original and the image drum unit chip was already replaced. Could it be the transfer belt? Many thanks
Hello, thanks for the video, I followed the cleaning instructions, but I still have a problem, when sending more than 2 sheets of some document, I get a ghost print of the watermark of the previous sheet, when I disassemble the transfer cartridge I notice that has remains of toner with the previous printing on it, apparently it is not discarding them, any solution? greetings from Mexico
Hola Bernardo! has conseguido resolver el problema que mencionas? Me trajeron una impresora que hace exactamente lo que mencionas, un "fantasma" de la impresión, pero sólamente es en la siguiente página. y no existe un segundo fantasma...
@@victoraguilars.4281 hola, no pude resolverlo ya que no consegui otra unidad de transferencia para probar, lo que hace mi cliente es mandar a imprimir una hoja por una, y asi casi no sale el fantasma ya que el repuesto es costoso, va a esperar a que se le termine el toner para desechar el equipo.
mi impresora samsung c460w no imprime a color y si tiene toner, se le cambio la cinta de transferencia porque manchaba mucho, ahora imprime pero no quiere a color, que puedo hacer?
Hi, thanks for your informative video. I bought a new transfer belt and fitted it as per your instructions which went well. But, when I turned the printer back on the error message "prepare new transfer belt" still came on. Any suggestions? Thanks.
After replacing the unit, you still need to reset the counter of the printer, which is done in the Tech Setup. To enter it, the combination of keys varies depending on the printer model - and unfortunately, Samsung didn't make them public (but they can be found for some models around the internet and on YT).
have a problem with my Samsung clp-365w. On power up it doesn't go through its usual warm up procedures. It is connected to the computer via usb. Removing the usb cable causes the conputer to sound so it knows it is disconnected from the computer. I think it is a hard wear problem with the printer itself. I have recently emptied the wast container. I worked after that but one morning after I powered up the printer all lights on the display came on steady and the printer didnt go through its usual warm up proceedures.
Great video. I'm sure the ITB for a Samsung CLP-315 isn't very different. Does the belt itself ever wear out? The symptom is a blurry line maybe 6-10 mm wide across that page--sometimes yellow toner, sometimes black. Samsung literature says to replace the belt assembly. Is the real problem likely to be the wiper blade, or that the belt itself is worn out?
Grazie, Signore Viandant. I've found that replacement ITB assemblies cost $US 65-$US 130. But replacement belts are $US 18-$US 20 from China and I now have one. I have a spare ITB assembly I can play with. I had one question, but now I have two: 1) Can I disassemble the assembly to the degree necessary to replace the belt? The Samsung repair manual suggest that this can only be done at the factory where special jigs are used. 2) Do you think that the wiper blade has worn in such a way as to damage the belt and would shorten the life of a new belt? Or perhaps that it's normal belt wear? (I realize that without seeing the blade both of us are just guessing.) I think I might go back to the China websites and see if the wiper blade is available. I love the CLP-315 and have used and used it. We also have a CLX-3175 (all-in-one). I have performed the special mods on both of these as described here: rumburg.org/printerhack/ . Don't try this on anything but a CLP-310 or 315 or CLX-3175. It takes advantage of a quirk in the firmware which was removed in later versions.
The right plastic lever shown you opening from the minute 1:18 was suddenly fell down of my printer, I tried to return it back but couldn't know how, any help?
@@viandant5 wow, thx for your fast answer on a 6 year old video, amazing! 🤩 Things started to get messy when my waste toner deposit was full and i've emptied it... the printer still complained about a full waste container so i put out all the parts as per your (very good) video - i think i got quite a lot waste toner out of the drum unit in the end, thankfully its still working without major print artefacts/issues - guess the drum is simply near the end of its life then (got the printer used already)
@@iNord. I always try to answer all questions! Waste toner depends on enviroment too. In winter and with high humidity there is more waste toner. If the quality is still goos, no problems
Hello, I have refilled on CLP365 only black powder on all cartridge by local toner for black printing ,now printer is working but sounding very bad , how can remove it , please suggest me how to remove the sound .
the bad sound may be related to the gears, the internal meshing bar or the toner powder. It's difficult to remove a bad noise, try lubricate all gears. If the cartridge is working I suggest you let it work
II think it's not an electonic problem to the main board, you should have an error message. It could be a mechanical problem, a gear or something not in the right position

Hi, this video has been most helpful. Upon cleaning the transfer belt, it has started to make very loud screeching noises when calibrating and printing. What can I do to solve this issue?
I the unit has been correctly assembled, I think you have to lubrificate the cleaning blade of the belt, or wait until the loud disappear

Not necessary to clean it often. MAy be 30-40.000 pages if there are no print quality problems
