Paper will not feed through - Samsung SF-4500c FAX

take the cartridge out. in the middel you will see a black roller at the back. clean it with soap.
if the rubber has cracks in replace the rubber.

clean all the rollers which pickup paper.

Open upper frame and you have to see paper feed roller, just clean it with cloth and water or alcohol.

Try cleaning the paer feed roller with a detrgent based industrial cleaner/ not an alcohol based one as this will dry out the roller and make your problem worse. If you are in a humid environmentyou may need to replace the paper in the paper tray and "fan" it prior to use, or it could be the paper feed clutch itself, which would be more complicated to remove clean and lube.

open the adf. the is the rop part of the printer where you put in the fax paper. clean the back black roller with soupe. close and test it

You should change the ADF roller JB75-00052A

if you have used the fax a lot or have used a cheaper quality paper the rubber feed rollers are slipping.

Open the unit up and use a bit of isopropyl alcohol on a paper towl and rub or clean the roller. Let dry and close it up again. That usually will clean enough to make it work again. If not the roller may need to be replaced.

There is a gray rubber pad on the upper half of the feeder.

Take the white piece off and turn the pad 180 degrees.

You have one of the paper path sensors stuck, or broken. I'm afraid this is a repair center issue, unless you are familiar with the disassembling of the unit. Good luck.

Be blessed.

You could try opening the feeder and clean the gray rollers with mentholated spirits and see how that helps as it just maybe the rollers are slipping slightly.

Once you have done the above take out all of the paper from the back feed and using one sheet blot the leading edge with some spirit and place back into the machine (The back of it) then try coping something there will be a paper jam and do this a couple of times. Once you have done this wipe the area dry put new paper in and then try doing a copy and the paper should feed perfectly now and the test will come when fax comes in.

I do hope this helps you
Thanks J
