My Pixma Pro-200 has been a great workhorse for printing black and white drawings over the years. It is suddenly not centering the paper, consistently being about 1/8 inch to far to the left when exiting the printer. It makes the right and left borders of my prints uneven. Any suggestions for a fix (other remembering to adjust each drawing before printing. Why would it suddenly be off center? I'm using the self centering guides when loading each sheet of heavy fine art paper. Any help would be appreciated-
