Color print Color will not print the paper just gets stuck. It looks as though the red toner is all over the inside. I can only access the blue toner. How do I get to the red so I can at least take it out?

If your MAgenta (Not Red) catridge seems to have dumped toner, (Alternatively, your used toner bag, may be full...) and the paper feed is stuck, then this is rapidly become a service technician problem. Does the control panel indicate any errors or problems?

I had the same kind of problem with the same printer.
The problem started with yellow toner powder 'leaking' inside the printer and contaminating the printed documents.

After inspection, the yellow cartridge showed what seamed to be like caked/cluttered powder between the magnetic roller and the doctor blade.
I dismantled the cartridge to realise the 'caked/cluttered powder' was in fact a sponge material. The internal 'spongy' toner feeder roller was damaged and little pieces of the material was coming out of the cartridge.

After further inspection inside the printer (all cartridges and drum removed), I found two little pieces of the same material stuck between the kevlar roll and the metallic housing underneath it. (going up, from bottom to top, you have the pile of paper in the feeder -> horizontal metallic plate -> kevlar roll -> toner carousel.)
I used a strip of heavy paper (200g) to gently remove the two sponges, set two clean jobs and the problem was solved.
The kevlar roll is also accessible from the printer's back door, some material may also be stuck in this location.

The supply status report is based on what the kill chip is reporting to the printer. If that particular color is not printing then it is likely that current is not flowing though a particular component in the cartridge. I would return the cartridge and get a replacement.

Many things can cause that, toner box full, fuser not heating, paper empty, toner empty, paper scraps inside, imaging belt used up, If the owners manual doesn't help you locate the problem you may need a shop. Samsung customer support can help too, you'll find their number on line.

You need a new drum

the red color contains the blue and magenta colors so your problem is not printing blue insted of red , your red laser miror is dirty from inside you should open the back of the printer then open the laser scaner then clean it then replace it

All color printers have a calibration mode.Essentially it makes sure that everything starts and stops at the same time.It should be accessible on the contol panel

You must pull 2 sided glossy from the stack bypass and set on color paper.

You are spilling blue toner. Try to vacuum out the excess blue toner from the machine. Be careful not to scratch the transfer belt.

The sound is coming from the new toner cartridges. The roller is sticking and causing the gears to make that noise. I removed the toner cartridge and manually turned the roller until it turned smoothly. (this a little hard but it worked). no more noise!
