RE: Pixma MX300. I just recently started having a no start on the printer side from my computer. The LCD says there is a paper jam, but upon inspection I found no such jam. The machine still insists that there is a jam and won't clear trhe error. I also was flashed a"check printer with a # 5100 in the lower right hand corner of the screen

It ia very muchpossible that If the paper tears and a piece remains inside the machine, you get this error, turn the machine off, open the Scanning Unit (Printer Cover) and remove it. Be careful not to touch the components inside the machine.
After removing all paper, close the Scanning Unit (Printer Cover), and turn it back on.

Reload the paper in the machine, and press the OK button on the machine.
If you turned off the machine in step (1), all print jobs in queue are canceled. Reprint if necessary.
If you cannot remove the paper or the paper tears inside the machine, or if the paper jam error continues after removing the paper, If you attempt to open your machine, be extremely careful when you take the scanner portion off, as the ribbon cables are rather sensitive and you really don't want to break them!! If you do decide to take apart your machine, you do so at your own risk!!

after opening the paper feed sensor in the 'Engaged' position, which tells the printer that a piece of paper is being fed through the machine. Upon further investigation, you will find a black wire tie that was blocking the sensor from going back to the OK position. It actually kind-of made sense, as when you got this machine, it was held inside the box by an insane number of these things, and one could very well have fallen inside, or fell in from the factory. After removing the wire and putting the whole thing back together, you need to power it on and low and behold, no more paper jam was being reported!
I have posted some pictures of the part in question, for those who might not know where/what to look for. I apologize if the clarity isn't the greatest, but you should at least be able to figure out from here where to find the problem on your machine (if it's the same sensor giving the trouble!). If you found this posting helpful, feel free to leave comments. Thanks!
RE: Pixma MX300.   - 07ddd1f.jpg Here you can see the paper sensor behind the roller wheel. You do have to take off the cover to completely see it, unfortunately

Here is a much closer image showing the paper level. When the machine is loaded with paper, the lever will be pulled forward, allowing the laser between the two pillars to shine though the whole way. Be sure to clear as much dirt and debris from here as possible. My cable tie was wrapped up around this lever, holding it forward all the time (so it thought that it was loaded with paper).

Here is a distance shot of the printer in it's torn-apart stages, showing you where the sensor is in relation to the rear of the printer. The large black piece sticking up is actually the flat piece of the printers insides; There are several fiddle wires holding this in place, I chose not to disconnect it, but with enough playing around you could probably remove it if you had to.

Canon Pixma MX300 printer had a paper jam. I took out the paper, and it was all there with no missing parts. It continues to say there is a paper jam - there appears to be no reason for the jam. I...

Try checking that a foreign object is in the paper feed rollers- do this by inserting a thin piece of plastic about 2 cm wide through the rollers from the paper exit side. Plastic like that from a shirt box (about 2cm wide by 20 cm long and 1 mm thick works well. I have solved this problem many times with my mx300 and it clears out objects which have droppped into the paper feed, such as Pens , yes pens. and paper clips etc which are otherwise hard to detect on this printer.

Skewed or crooked paper uptake on Canon Pixma Mx300

Sounds like the roller(s) on the left side is missing or is slick (or split). You should have returned it to the place of purchase when you discovered the problem.
