Error code 5100 on Canon inkjet printers

Solution 1:
  • Look inside for a tiny object like a piece of paper, a staple...

Solution 2:
  • There is a thin plastic strip running across the width in front of and below the drive belt: there are fine black vertical lines on this strip. 
  • If the strip gets a piece of crud on it, you get an error during the start-up sequence.
  • Gently clean this strip with a damp lint-free tissue.

Solution 3:
  • The purge cap (the white sliding mechanism that the print head parks to when it's not in use) may be not lubricated well enough. 
  • Lubricate the sliders with some white grease (don't get it on the small wipers or the black caps).
  • This repair probably require to remove the right panel off of the printer to gain access to the purge mechanism.

My daughter has removed this strip and I don't know how to put it back. Could you help me?

I repaired this problem just by pulling the stripe a little bit!! :)

Hi, my stripe was dirty with grease from the rail below - must be happened while fixing the paper jam. With the clean stripe my mx700 runs fine again! Thanks a lot!!!

Thanks for the hint -- helped me locate and fix my problem. Turns out it wasn't a dirty strip, but a long piece of curly yellow ribbon that had somehow gotten inside and wrapped itself around that area. Life with a 2-year-old.
