Hello, I’m Nathan, and I’ll be assisting you today.

Sorry to hear that you’re having trouble with this but I’ll do my best to help you out.

What is the make/model of your printer?

Customer: replied 7 months ago.
Canon Pixma MG3520
Expert:  Nathan replied 7 months ago.

That is an alarm light noting an internal problem.

Can you tell me exactly which lights you see (they are all labeled), what color, and what pattern (such as flashing 7 times, pause, 7 more, etc)?

Customer: replied 7 months ago.
There is a blue light, a light green, and now the on light is blinking

I need specific details, please, for me to be able to give you an accurate answer.

Can you tell me exactly which lights you see (they are all labeled), what color, and what pattern (such as flashing 7 times, pause, 7 more, etc)?

Customer: replied 7 months ago.
The on and off is labeled A and the blinking triangle is labeled Bthe on and off
Expert:  Nathan replied 7 months ago.

So it is just a constant steady flashing? No pattern at all?
This is very critical to a proper diagnosis, as the flashing light is like an error code that tells us what the problem is, so that it can be properly addressed.

Customer: replied 7 months ago.
There is a motion of off and on back and forth,.Like 1234 than a pause.
Expert:  Nathan replied 7 months ago.

So it flashes 4 times, pauses, 4 more, and repeats?

Customer: replied 7 months ago.
Thats correct. Can you help me?
Expert:  Nathan replied 7 months ago.

There are a few possible causes of this issue, including a bad cartridge, internal debris/contamination, or a hardware failure (bad printhead, bad logic board, faulty sensor, etc).

What we can try are some cleaning and reset steps.

First remove all of the ink cartridges, then clean the metal electrical contacts on the back, as well as where they mate up inside the printer, using qtips and rubbing alcohol. Dry well, then reseat the cartridges.

Then reset the machine:
unplug power at the wall outlet
wait 5 minutes
press and hold the power/on button for 60+ seconds
keep holding while plugging back in, and for another 60 seconds after, then release

Let me know the results, and I'll advise further if needed.

Hi,No Luck.
Expert:  Nathan replied 7 months ago.

Are you using genuine canon cartridges? Refilled/generic ones?

Customer: replied 7 months ago.
I am using 241xl color and 240 remanufactured black.These cartridges have worked before with no problems.But i will get the canon cartridge (black) tomorrow.I have to do dinner now. will let you know tomorrow. Many thanks.Good Night Nathan.
Expert:  Nathan replied 7 months ago.

Thank you, ***** ***** be the next step. Even though you've had good luck with them, those cartridges have very high failure rate and don't generally work long term. I'll wait to hear how it works out when you have a chance.

Thanks,
Nathan
