    Will check toner again just to be sure. Thanks

  • Drsms22 Nov 07, 2007

    There is a full toner cartridge and the red and green lights are still alternatively flashing quickly.

    I am having the same problem as well. I have recently replaced the cartridge and all was fine until suddenly I have this problem. I have switched the printer on and off, opened all the bits I can open to try and reset something but no change.

I noticed that the orange cancel button was jammed down. I couldn't prise it up, but was able to release it by tapping firmly the top of the printer near the button. As soon as it popped up - the buttons stopped flashing

The same thing happened to me and I just hit it on the sides and it fixes it. Hint in life: when something doesn't work, hit it!

Bridiek's suggestion above was right on.  I tried prying orange button up but it was too far down to get instrument in so I tapped with my fist next to the orange button, it popped up.  I turned printer off and on using the power switch on the side and everything returned to normal state.  Thanks, Bridiek!

Thanks. Same here. Unstuck orange button. No problem

I had the same problem as the user above, used a sharp knife and pried the button up, it indeed was jammed, and that fixed the problem. Thanks.

Have you checked to see if you have any toner left? That is the signal for it on this Samsung.

Hi there,

A red blinking light on a samsung printer will often indicate that your toner level is low. It will still continue to work until the toner fully runs out. This is Samsung's warning saying that you should think about changing your cartridge soon. I hope this helps.

Red light blinking not printing

Based on your error, the manual says that your toner is low or empty.

I have a ML-2510, I turned it on and both the red light and green light flash constantly. Will not feed or print.

The green light blinking means that it is accepting or printing data.
But, the red light is for the error messages. This blinking means there is a toner problem. 1. remove toner cartridge from printer and gently shake to redistribute any that is left, or
2. You simply have to replace the toner cartridge with a new one - this one has been exhausted.

Samsung printer ML 2510 series

Maybe the toner is low... According to the manual, a blinking red light:

• A minor error is occurring and
the printer is waiting for the error
to be cleared. When the problem
is cleared, the printer resumes
• The toner cartridge is low. Order
a new toner cartridge. You can
temporarily improve print quality
by redistributing the toner. See
page 8.3.
• The toner is totally exhausted.
Remove the old toner cartridge
and install a new one. See page
• The toner cartridge reached the
end of its life.

Do you have a paper jam? If nothing is wrong it may be internal hardware error. Call Samsung for help.
