Thanks for your interest.
The article did not address the problem. I have been using Pixma 922 for many years, I am now on my third machine. I am familiar with the procedures for loading paper - which is the topic of that article. This twisting problem has appeared recently. I am not using Canon photo papaer, but the brand I use has not caused problems before. The twisting happens with 4X6" paper, a single piece of 5"X7" normal paper went through straight. I have been assuming that there is some small blockage or irregularity in the rollers, but have gone through the cleaning procedures, and physically explored and cleaned as far as I can - but I am unable to fix the problem. The machine is under warranty
