Re: Toner light on

Open the front cover and leave open while completing the following steps: Turn the printer off. Hold the 'go' button while turning the printer on. All panel lights should be on. Release the 'go' button. Press the 'go' button 2 times. Pause. Press the 'go' button 5 times. The toner light should be off. The paper light should be on. Close cover. The ready light should be the only light on.

My newly installed Samsung CLP-310 has a red light showing next to the <...> icon. Please could you help me to resolve the problem. Thx

Hi paulette,
if the light is red and TONER COLORS LED all LEDs off

• The machine is experiencing an error, such as jammed paper, open cover, empty paper, installed waste toner container, or full waste toner container.
• The machine is experiencing a service required error, such as LSU error, fuser error, or Contact your sales or service representative.

if the light is red and TONER COLORS LED each LED lights red.

• Each toner cartridge is totally exhausted. You can not print.
• Each toner cartridge is wrong.

Have put in three HP factory new cartridges - same thing happens each time - first 3 pages are GREAT - PERFECT - and then subsequent pages are light, looks exactly like I need a new toner

Hi there !

Have you shake your new toner cartridge before your put it is because maybe you purchase old stock that makes them stick together. If not do it to distribute evenly the toner.

I already replace a new toner but there an error msg AP

The AP message indicates thet the dev is so low in toner that the machine has to go into a full cycle mode to get the toner levels up.
The error code is telling you that one cycle is not enough. you will have to turn the copier off/on and cycle it at least one more time....more if neccessary

Oki C3200n Says Order K Toner after install

Two possible problems:
1. You actually got a partially empty new toner. This has happened to me once.
2. The sensor on the printer is dirty and not seeing the toner. With the toner there is a little wipe that says it is for cleaning the LED. There is an LED sensor that "reads" the presence of the toner. If this is dirty it will think there is no toner cartridge.

I got exactly the same problem and the "reset" didn't do anything. I fixed it by putting a piece of duck tape on magic eye on the cartridge.
Fallow those step to do the same thing as me:
  1. Open the front panel.
  2. Remove the toner and the drum
  3. Remove the toner FROM the drum
  4. On each side of the toner, there should be a little glass. Put the piece of duck tape on one of them. I put mine on the right side.
  5. Put everything back in.
  6. Turn on your printer if it's not already.
  7. Now, the low toner light should be gone and the green light should be on.
Now, you can really empty your cartridge.

Toner light doesnt go away in our printer and the printer doesnt print. We changed the cartridge please help us

The HL-2070N gets jammed in a toner end-of-life error condition. Perform the following to clear (I have 120 in the field so I know it works!):

With paper loaded, new toner in,

  1. Open front door
  2. Turn off printer
  3. While holding down the GO button, turn printer back on
  4. When all four LEDs light up release GO button. All LEDs will turn off
  5. Press the GO button 2 times. The 3 LEDs (toner, drum, paper) will light up solid
  6. Press the GO button 5 times
  7. Paper light will be blinking
  8. At this point the toner end-of-life condition has been reset. Close front door.
BTW, I got this from Brother Support. Also, just a reminder, timing is important here so don't pause between button presses.

How to reset Black Toner Empty Message on 2430Dl

There are many problems like that and its not recommended to change toner from one printer to another.
but you should try: put the old toner (emty) in again, then turn off the printer, change toner and turn on printer again.
if thats not helping, then maybe you have a old FW so you can try to update the firmware.

Stopped printing after I installed new Toner!

If the new toner is original, your unit just burned the fuser. If it is under warranty, any Samsung Authorized Service Center will gladly replace it for free.
