MY PRINTER'S ALARM LIGHT IS FLASHING AND SHOW ERROR 2 CAN YOU HELP ME ?

According to the Canonwebsite 7 flashes indicates that the incorrect Print Head has beeninstalled. I know it is sometimes possible to fit a Print Head from adifferent printer into a Canon printer - it'll fit but it won't work!

I don't know what your exact model is, but just go to the canon website
http://www.usa.canon.com/home and search for your printer model.

Should be written on the outside of your printer. Find your printer on the website, and it will tell you exactly what printer ink cartridge to buy.

Please rate me, and leave a comment, or if you still need help post an other message in a reply to this, so i can follow up and help ya further.

Hi again,
-not sure if you have resolved your issue, but in case you have not...this is a preliminary solution
-if you need more help...just post a comment..as this will automatically put it in my account to see * respond to

-anyway....this is an excellent high quality printer!
-the flashing amber light on the printer indicates that it is offline..ie. not ready to print
-to fix it...
-assuming that there is paper in it & that the cables are fully connected
-on the lower right...press the resume button once (within the 2 button right hand lower area)
-this should put it back online...and help you to print
-if you need further help...just ask

as well...remember to rank...but understand that anything other than a FIX-Ya..actually lowers my rank...so if the above doesn't help...just ask...
thanks

My printer wont print. It flashes Error 5100 and the orange light flashes twice. There are no answers in the book.

Try removing cartridges and manually claening the heads with cleaning solution and cotton bud (q-tip) replace. Print. No luck? Now try uninstalling and reinstalling printer.

Only thing I do is to re-boot the printer and check your print size is the same as the paper size in the printer.. pretty poor this
