Hi,
Double check to make sure the front cover on the printer is closed completely and clicks into place. Also, if you recently replaced any inks, make sure they are installed correctly and not loose.
If the alarm light still does not stop blinking, the printer will require service.
If the printer is in it's 1 year warranty, I recommend reaching out to Canon support for your warranty options. You will need to register your Canon gear HERE to access additional support options.
If the printer is out of warranty, you would qualify for the Canon Upgrade program. This is for out of warranty units which have been diagnosed to require service or are incompatible with a new or upgraded system. This program allows you the opportunity to purchase a replacement product discounted from the list price. Free ground shipping is included with your purchase.
