Canon i550 Service Error 5100 - fixyourownprinter.com: "Re: Canon i550 Service Error 5100 by FIXED IT! (8/31/05 9:43 AM) reply / -
I fixed this f*cker before. Trust me its hard. As Barry pointed out this error is an error within the printer. This error means that there is something obstructing the printing process. Check inside your printer through the gears that you can see under the lid. There should be something obstructing the gears such as dirt or in my case popcorn. There was even some paper caught underneath the rollers that I had to jiggle around to even see. Check VERY thoroughly.
