How I fixed printer Canon TS3322 paper is not feeding. 

My Canon printer TS3322 was not feeding paper.
Steps
Check for paper loaded correctly.
Make sure you are not loading too much papers.
Load paper in the portrait orientation.
Always, unplug it from the power supply before touching or open printer. Look for foreign visible objects in the rear tray.
Clean the paper feed rollers put to a cotton ball a little alcohol and proceed to clean. Warning (Never put liquids directly to printing!)
Test the printer. (Unplug from electricity)
If the problem continues use a piece of cardboard feed it in the printer and look for foreign objects. Remove slow if possible.
Test again and see if it fixed. Thank you.
