Canon pixma ip1900 paper jam

Hi
Here's a few things you can try :-
1. Blow it out with canned air. make sure there are no bits of paper or dust in the paper feed area and in the front access area that could be causing the jam.
2. Verify that the cartridge carriage moves to the service area when the front door is opened (as if to change tanks)
3. Verify that the timing belt, drive belt, gearing and rollers all look normal.
4. Take the network out of play when doing the initial troubleshooting
5. With the computer off, unplug the printer's power cord and USB cord for about 3-5 min
6. Completely uninstall the printer's driver and software. Then reinstall the printer's drivers only.
Retry after each step.
Also if your Canon printer has fax capabilities, and you are getting a false paper jam error, the problem is easy to fix.
Open the scanner lid.
You will see a white strip on the left, under the lid.
There are also two small, white tabs near this strip.
Gently pull on each tab. You should feel a small "click" on the tab that is jammed.
This fixes the problem.
I suspect that when previously scanning something like a book page, one of these tabs got pushed the wrong way.
Hope it will help.Also you can get back to me if you need further assistance.
Thankyou.
