Error #1003 no paper. load the paper in the cassette correctly and press the resume button. I have tried this numerous times and the machine keeps making the noise as if there were no paper in the feeder. lous clicking noise. I have tried shutting off and still nothing is working.

The canon printer error code 1003 appears when you have No paper in cassette / paper not loaded properly in the cassette.

Try this to correct the problem:

1.Close the paper output tray.
2.Pull the paper feeder tray out.
3.Insert a stack of paper until the top edge touches the far end of the feeder.
4.After loading the paper, push the feeder so that the arrow mark on the front tray aligns with the arrow mark mark on the printer.
5.Open the paper output tray, then press the OK button on the printer.

Automatic Print Head alignment failed
Possible causes are as follows:
A4 or Letter-sized paper is not loaded on the Auto Sheet Feeder.
Press the RESUME/CANCEL button on the printer to clear the error, then load one sheet of A4 or Letter-sized paper in the Auto Sheet Feeder.
Automatic print head alignment cannot be performed using paper from the Cassette. For automatic print head alignment, always load paper in the Auto Sheet Feeder.

Press the RESUME/CANCEL button on the printer to clear the error, and then print out the nozzle check pattern to examine the print head condition.

For information on how to print a nozzle check pattern, see "Printing the Nozzle Check Pattern."

Press the RESUME/CANCEL button to clear the error and move the printer to a darker location.
After carrying out the above measures, if the problem continues after aligning the Print Head again, press the RESUME/CANCEL button to clear the error, and then perform manual print head alignment. For details on manual print head alignment, see "Manual Print Head Alignment."

Many times the switch that lets the printer know it's out of paper is stuck in position, or dust has clogged it. If you can blow the small bits of paper or dust out you can get it going again. I use a can of compressed air to clean my printer about once a month to stop this from happening. It is a common problem.

Another possible reason for getting this error is a dusty printer. I don't dust very often so dust piles on everything, including my printer. My daughter wanted me to print something for her and the first page went through just fine. But the second never started and I got error 1003. I had plenty of paper loaded and my settings for the size of paper were correct. I dusted out my printer and everything else printed just fine. My theory is the top paper had dust bunnies on it that were pulled into the printer when it pulled the first page in. Maybe the dust got caught on a sensor that told the computer there wasn't any paper. Regardless of what happened, a quick cleaning fixed the problem. I just wanted to throw in my two cents for anyone out there that may have a dusty printer and run into this error.

Ten flashes:The Cassette is not installed properly/Cannot perform duplex printing

• When loading from the Cassette, install the Cassette properly and press the RESUME/CANCEL button.
• When performing automatic duplex printing, the size of paper may not be compatible with automatic duplex printing. The sizes of media suitable for auto duplex printing are A3, Regal, 11" x 17" (Tabloid), B4, A4, Letter, 10" x 12", 8" x 10", B5, and A5". Make sure that the size of the paper loaded in the printer is correct. Pressing the RESUME/CANCEL button will eject the paper and restart printing from the front side of the next paper. The reverse side of the ejected sheet will not be printed.

Hello Brian,

I found the following on Canon's website.

Not sure if it will fix your issue but thought it might be worth a try:
