How to fix error code 5100 on any Canon Pixma Printer

See this video for solution for error code 5100:

There is a thin (1/4"wide) plastic strip running across the width in front of and below the drive belt. This part is related to the optical encoder which tells the print head where it is. Look closely, 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. Softly clean this strip with a damp lint free tissue. This also fixed a gap in the printing running lengthwise (not across the page like a clogged head).

Hi You can Try

Error Code 5100
Solution 1:
Clean the timing strip.

Solution 2:
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.
