Thanks for the link. I did a Google search and found LOTS of people have mysterious paper jam problem with the Pixma. One person mentioned a trap door in the back. Sure enough, there was paper hiding back there. So, problem solved. I will be able to take my vacation after all. :-D On Sep 4, 2008, at 3:33 PM, Mike Finn wrote: > Check out this forum - looks like turning it upside down and shaking > has helped several people: > > http://www.fixya.com/support/t119769-false_paper_jam_warning_canon_pixma > > Neil wrote: >> I bought a Cannon Pixma MX 700 multi-function printer/scanner/fax >> (thanks Randy for the recommendation).
