Hi


If the Paper Output Tray is closed, open it. The machine resumes scanning.If opening the Paper Output Tray does not resolve the problem, or if the tray was open to begin with, the paper may be jammed. Remove the jammed paper, reload paper properly in the printer, then press the Black or Color button.

The simplest thing would be to try unplugging the printer from the power source. Let it rest for 5 - 10 minutes then plug back in to the power supply and see if that resolves the problem.

If not you are going to need to do a thorugh inspection to verify that all paper remnants have been removed.

The following is for the MP600:

Clearing credit card-sized paper jammed inside the printer
Credit card-sized and 4" x 6" sized paper must be loaded properly. If this media is not loaded properly, it will feed into the printer and will not exit. Credit card-sized paper should only be loaded in the ASF and in portrait orientation. 4" x 6" sized paper can be loaded in the ASF or cassette. But must be loaded portrait orientation.
If credit card-sized paper was loaded in landscape orientation in the ASF and did not eject (exit), please follow this procedure.

1. Turn off the printer.
   
   
2. Load the same paper type that is jammed inside the printer in portrait orientation.
   
   
   
   
3. Power on the printer.
   The paper stock in the ASF will automatically feed the jammed paper from the printer.
   
   
4. To resume printing, load the paper in portrait orientation.

If 4" x 6" sized paper was loaded in landscape orientation in the cassette and did not eject (exit), please follow this procedure.

1. Turn off the printer.
   
   
2. Open the rear cover.
   
   
3. Fold in four a piece of letter-sized plain paper.
   
   
4. Push in the folded paper until it hits the jammed paper.
   
   
   
   
5. If the jammed paper is visible from inside the printer area, pull it out and proceed to step 7.
   
   
6. If the jammed paper cannot be pulled out, push in the folder paper from the rear so the jammed paper is in between the feed rollers.
   
   
7. Pull out the folded paper and close the rear cover.
   
   
8. Power on the printer and confirm that the Alarm light is off.
   The jammed paper should automatically eject.

The JAM DUPLEX message appears if you remove a sheet of paper from the face down output tray after only one side has printed.
The paper sizes you can use with the duplex printing function are A4, Letter or Legal.
If the paper adjustment lever for duplex printing is not set correctly for the paper size, paper jams may occur and the printing will be out of position on the page.


Open the back output tray.
Use both hands to slowly pull the jammed paper out of the fuser unit.

Close the back output tray.
If the paper jam cannot be cleared, go to the next step.
Pull the duplex tray and paper tray out of the printer.
Pull the jammed paper out of the printer
Put the duplex tray and paper tray back in the printer.

Click solved and vote if problem is solved. Otherwise post again

That error usually comes from the sensor under the platen roller. It's a tiny black plastic piece that the paper pushes when it passes under the platen roller. The end can bend when you pull out a jam, or a tiny paper scrap can hold it down. The same screen gives error codes when there are other malfunctions, the error now is just that sensor.

Canon Pixma MX300

- new cartrige for Black ink
- can scan
- can photocopy documents
BUT can't print documents from my MacBook eventhough the paper feeds and goes out at the other side

Step1
Turn the printer off and on to see if it can automatically clear some or all of the jam. Many printers provide an error-code listing on the front panel display for the area where the jam occurred. If your printer shows an error code, be sure and check the printer manual to see if that identifies the area of the printer where the jam occurred. 
Step
2
Turn off the printer. 
Step
3
Remove any paper trays. Inspect them for wrinkled or damaged paper. 
Step
4
Open any other doors that give access to the printer's paper path and to the toner or ink cartridge. 
Step
5
If necessary, remove the toner or ink cartridge. Place it in a bag or away from light to avoid damaging it. 
Step
6
If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly (see A). The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam. 
Step
7
If the paper does tear, try rotating the roller gears manually to free the paper (see B). Don't force anything, though. 
Step
8
Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on. 
Step
9
If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.

Pixma MX860. Got a "Paper output slot. The paper is jammed. Clear the paper and press OK" message. This happened out of the box new. The solution was the replacement of the printer. Cannon is sending a tested model and providing return postage to return the defective unit.
