I agree with the idea of advancing the media three inches or so after printing in almost every case. However, it is useful to know you can tape some media on in case you forget, or to save material. For example, vehicle grade reflective is expensive.
I think it's a good idea to slow down your cut speed too while setting you pressure. Also, if your printer allows for tests cuts, use it often. Blades dull over time and other conditions can vary. Doing a test cut can avoid trouble, like cutting through the sheet, jamming as a result. Also, cutting too deep (through the sheet) is very hard on the backing strip.
I print with the outside rollers only, leave a bit of excess on the sides, and after laminating- reloading, put all the rollers on/down while cutting.
Always double check that the " dot alignment" is complete ( not just sheet setup) before sending the cut job. My machine displays a "123" code on the printer panel. (I do mine manually, bring the cutter out with the panel controls and hover over the first circle and press auto align on the printer).
Finally, if you are cutting something like vehicle reflective, keep one blade for that and change it in and out. And, you should remove the media and roller bars fom the back of the printer on large (most ) prints to avoid jamming etc. when the media backs up to cut.
