The alarm light is flashing and it won't print?

try reinstalling the printer driver again

clean the encoder tape

The security light will only flash if theres a problem, are you talking about when the alarm is on and car is off the secuirty light doesnt flash, if thats the problem then the alarm may not be arming or the light is bad, there may be a module problem.

To fix this you first need to remove the ink and the print head.
Wash the 4 ink pads in luke warm water.
Keep running the water over the bottom of the print head until the water shows no sign of ink colouration.
Make sure all of the print head is completely dry before replacing it into your printer.
After restarting your printer you will probably see the alarm light still flashing.
Now hold your finger on the resume button for up to 2 minutes or until you hear a clunking sound.
Hold your finger on this button and the printer will fix itself and the alarm light will stop.

Your machine needs to be serviced.
replace the cartridge with the original one.
it can not print if one cartridge is missing or not original.

hold down stop/reset button for 7 sec. If that doesn't work try holding it down for 14 sec.
