I use Linux. Ubuntu 14.04 LTS (Trusty Tahr). About 1 month ago, I purchased a Canon Maxify MB2320. I have a problem, every time I print or scan, the driver writes a file into /var/tmp. A week ago, I had so many I could not boot the computer. There was over 1 gigabyte of these files in /var/tmp. Is the driver a problem? I do not relish the work of removing these objects in /var/tmp on a daily basis. These cnij* do not go away after a warm or cold re-boot. Is Canon working to fix this? If Canon's lawyers are concerned about Linux, copyright and liability, they shouldn't be. There are plenty of Linux coders ready, willing and able to remedy these type of problems. I would much prefer to use the Simple Scan app for scanning and not Canon's scangearmp2, as it has to run from a terminal. Any advice, information or help much appreciated.
