All lights keep blinking

Got back from work yesterday and my printer lights were all blinking. I tried to turn it off but it wouldn't work that way. Only way to turn it off is unplugging the whole unit. The buttons are all not responding. How can I fix this problem, have never had any problems with this printer. Greg

Re: All lights keep blinking

I would try some simply things first. 1. Pull the power plug and wait for approximately 15 to 20 minutes before plugging back into outlet. 2. If your power plug is plugged in a power strip then try pluggin directly into the wall outlet. 3. I would make sure there are no paper jams. 4. If you recently installed ink cartridges, then check to make sure they are the right make and model for your printer. Comments: If you had a power surge the printer may just need to be powered off for awhile. Some printers will hold there settings for at least 15 minutes.

Cannon MP830 Printer purchased in July, 2007. Was working fine until yesterday. suddenly when printing from PC get "Service Error 5C10 and printer alarm light begins blinking". When trying copy -...

It is one of two things.

a bad ink cartridge (the chip located on the gold part of it)
bad USB cable.

IF you have a spare cable simply change them out.

If you are refilling your cartridges, it is time to replace them.

Printer light keeps blinking after being pluged in

Please follow the instructions given below:

1. Disconnect the USB cable and the printer power cable.
2. Please disconnect the power supply from the back of the printer.
3. Then remove the cartridges from the printer.
4. Please reconnect the power supply back and turn on the printer.
5. If lights are blinking then printer encoder strip is most likely the problem. Unplug the power from the printer. Open the front cover and move the cartridge carrier to the center. You should see a white ribbon cable, a thin plastic strip and a black belt with teeth.
6. The thin plastic strip is the encoder strip. It rides in a sensor on the back of the cartridge carrier that you will not be able to see. Reach in with the first finger of either hand and carefully strum the strip as if playing a guitar.
7. The strip will need to be lowered slightly and brought towards you slightly. Please be careful not to break the strip or your printer will not function. Once you believe the strip is set correctly, plug the power back and let us know if the lights are still blinking.
8. If you cannot repair the strip, please let us know so that we can assist you further.
Please Note: Fixing the encoder strip is a delicate procedure. During the troubleshooting, if the strip breaks, you will not be able to use the printer. We will replace the printer, only if it is under warranty.
9. However, if lights are not blinking then try inserting one cartridge at a time and check if you can see any lights blinking. If light blinks with one cartridge then that cartridge is defective.

I had the same problem just yesterday. Turn off the printer for 10 seconds. Then turn back on. Turn back off again and unplug from the electrical outlet. Open the control panel and tilt it toward you. Close the control panel, plug machine back into the outlet and turn back on. I did this and it solved my problem.
