Error 5100 fix for Canon MX700

[jarhed1964]

I had to register to post this. Just bought an MX700 from a guy for $40. Was not printing in black at all. Error 5100 out the wazoo!

I used the following procedure (about a minute and a half of "work") to clear the Error 5100 and it started printing PERFECTLY!!!!!

I had the same problem and tried greasing(actually WD40)per linzi's reply, but it did not help. In the process, I think the solution presented itself. There is a thin (1/4"wide) plastic strip running across the width in front of and below the drive belt. This is part of the optical encoder that tells the print-head where it is. If you 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. Gently 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).

ANYtime!

I'm going to spread that fix all over the internet if I have my way! It's so easy and will hopefully help the OP as well as anyone else looking for an MX700 fix.
