Red light blinking not printing

Dear
You can use EPM(easy printer Manager) or smart panel. These files can down loaded from the samsung site. install and run in the PC it will show the status of the printer.
The red light blinks and printing is possible means get ready to replace the toner cart. with a new one.
Thanks. Printer Support SAMSUNG India

If the red light blinks it means that the toner crtridge need to be changed, but it will still print for some out prints.

Do you have a new toner cartridge loaded? The red/orange light will blink when toner is low, even if everything else is working fine. Try printing out a test sheet and see what that tells you about your toner level. (Test sheep prints by holding the orange button down a second or two and releasing.)

Since I'm mainly printing drafts for my own use, I've just let the light blink while I eke out whatever I can from the remaining toner (occassionally removing the cartridge and shaking it -- being careful of clothes and surroundings -- to re-distribute the toner on the inside.

yes

This answer may be a bit late but if this flashing of the red and green light is accompanied by a sound of a motor starting and stopping over and over, it is NOT toner, but a defective capacitor in the power supply. Here is a photo of the part that is creating the problem. I am not responsible for any harm done to yourself so please make sure you know what you are doing.

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
printing.
• 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
8.4.
• The toner cartridge reached the
end of its life.

I think its the toner low light, press the orange button to print a test page with diagnosis

no, I have paper....the red-light on the top keeps blinking.....

I have used akums-razor to determine the answer.....

sol: push and hold down the orange button for 3-4 secs and wait for a print-out. It will give you the staus of the toner cartdg. MINE REPORTS A LOWWWW LEVEL. ( the orig. cartridge gives the user only about 1000 sheets and mine is around 783. This is why I think the light came on to tell me to jump in my Lexus, get down to Best Buy, and get another ( more capacity) new cartridge....
cool, huh?:>))))

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