Printer Problem the printer lights are flashing and it doesn't run

Have you tried unplugging the printer from the wall for 5 minutes to reset it? If that doesn't work you either have a defective ink cartridge or the printer is defective. Due to the very low prices of new printers replacing it in almost all cases is the cost conscious thing to do.

Ok sir try to turn off the printer if it doesn't. Pull the power cable shutdown your computer then plugged again the power cable of the printer then turn on the pc and printer..If it doesn't change contact a printer technician or bring the printer to the nearest service center. Hope it helps you..

that is because ur head of ur printing cartridge is damaged.

remove ur cartridges black as well as color
n install only black cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur black cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of black cartridge is damaged
after this process remove the black one cartridge and install the color one cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur color cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of color cartridge is damaged
now take a dry cotton cloth n gently clean ur cartridges head install both cartridges on ur printer n check ur blinking light on ur printer that will work only if u r too lucky other wise u have to purchase a one cartridge.

5 flashes indicates a faulty printhead or possibly a problem with the p/head contacts. Try removing the head which is easier if you take the cartridges out first(no tools required) and re-seat it having checked the contacts for dirt.

If that doesn't work it may be that the waste ink tank is full. Try this ...

Canon S9000, S300, S400, i550, i560, i850, i860, i865, i9100, i9950, PIXMA iP3000 above,
1. Turn off printer
2. Hold down Resume button and press Power button.
3. Keep holding down Power button and let Resume button go.
4. Press Resume button 2 times then let BOTH buttons go.
5. Green lights will flash and then stop blinking.
6. When green lights are solid, press the Resume button 4 times.
7. Press the Power button and the printer should turn off, if not, press the Power button once more.
8. Your printer should respond as normal.

Try unplugging the printer for fifteen minutes or so. If that doesn't do it then it it your main board. Sorry for the bad news.
