CUPS Driver Information * When "Canon IJ Printer" is selected although the current driver (lower than 10.0.0.0) is not installed, an error message "An error occurred while trying to add the selected printer. Error: -9672" will be displayed. Install the current driver (lower than 10.0.0.0), or use the CUPS one.
An error message may appear and the printer will not print as long as the paper output tray is closed. To fix the issue: Place your fingers in the slot at the top of the paper output tray.
If TWAIN scan applications quit unexpectedly when launching or display an error message then quit, move third party data source files from the TWAIN Data Source folder*.
