Supply rec paper cassette message on Canon PC1061?

This error comes when the paper is not loaded properly in the cassette ... Follow the below instructions to load the cassette and I am sure you will not get the error again.

1. Grip the cassette handle, and pull it out towards you until the cassette comes to a stop.
   
2. Open a package of paper, and remove the paper stack. If the paper is curled, uncurl it before placing it in the cassette. Failure to do so will cause paper creases and a paper jam. 17 lb to 20 lb bond (64 to 80 g/m2 ) paper is acceptable. The cassette holds up to approximately 500 sheets of 20 lb bond (80 g/m2 ) paper.
   
3. Load the paper stack beneath the cassette's length guide (1) and width guide's claw (2).
   Make sure that the paper stack does not exceed the length and width guides' claws in the cassette. Failure to do so will cause a paper jam. Do not load extra paper when there is still paper left in the cassette. Only load one size of paper into the cassette. Do not load different sizes of paper into the cassette at the same time. Do not load labels or transparencies into the cassette.
   
   
4. Gently insert the cassette as far as it will go.

The cassette is for plain paper, colored paper or recycled paper only. Loading other paper in the cassette may cause a paper jam. If copies are curled, or a paper jam occurs, remove the paper stack from the cassette. Turn it over and then place it in the cassette. If you load paper while making copies, do not load a different paper size.
Closing the cassette When closing the cassette, make sure to push it in completely as far as it will go. If copying is performed when the cassette is not pushed in completely, it will cause a paper jam.

If copy paper is sticking out of the cassette Sometimes, when you pull out the cassette, paper may stick out. Make sure that the paper is neatly loaded into the cassette, before you push the cassette back into the main unit.------------
