Firstly try attaching scanner to a computer running an earlier version of windows and confirm the scanner is working OK.
If you are satisfied the scanner works the problem may lie in the fact the Windows VISTA does not have the necessary driver and/or does not support this scanner. Your alternative is to go to hamrick.com and download a trial version of vuescan which should get the sanner working. If it does, then may be worthwhile investing in the program and happy scanning.

Turn the printer on.
Lift the printer cover until it locks in place.
The empty cartridge will be flashing.
Remove the cartridge by pushing the front clip and lifting it out of the carrier.
Remove the wrapping from the new cartridge and the orange protective cap from the cartridge
Insert the cartridge and press it down until it snaps in place.
Close the cover.
Run the nozzle cleaning utility and the alignment utility.

Yes, 5100 means the carriage is not moving back and forth properly or there is grease on the encoder strip behind the carriage assembly. Grease spots make it lose count and slam into the side and grind gears. You need to clean the strip with a Q-tip moist with alcohol, but very carefully, not too much pressure on the strip.

8300 might be an error shown on your computer, I need the actual error shown on the printer display.
B300 however is a reactor fluid delivery error and should be covered under the one year warranty.

Take it to a Canon Repair company, It has a 1 year warranty and needs to be replaced or call 1-800-ok canon.
