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. 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.
