ANSWER : Been working on these since they first were released. Never seen a problem like yours. If it happens again, try doing an engine test, as it bypasses the formatter board. The engine test is located at the right side of the manual tray opening. Look for a hole in the side wall. Stick something like a paper clip into it to actuate the test button. It will then print a lined test page. If it does that, then it points to the formatter board as the cause of your problem.

Prints blank pages, won't print from computer
ANSWER : Don’t know why you replaced the fuser, but assuming you had print before, then it must have been something you did during the procedure. Only thing I can suggest is to recheck your work.

canon mx320 copies have blk line down the right side of copies
ANSWER : If you are using the ADF feeder to make copies, then check the small glass on the left side. If there is any dirt or whiteout on the glass, it will result in a line down that spot. You can confirm it by looking at the copy that has the line. If it is dirt on the glass, the line won’t go all the way from top to bottom. There will be a margin on each end.
