A couple of tools makes very quick work or routine cleaning.

First, I use a lighted inspection mirror to see if there is any debris on the bottom of the nozzle. This is a great quick check because I don’t have to turn off the machine, I can inspect it in place. The photo show some buildup from some paper that I have been testing for demonstrations.

To remove the lens assembly, a 2.5 mm ball end hex screwdriver is my tool of choice.

I hope this helps folks with routine maintenance.
