Unfortunately methinks there's a problem with the video. The author
ends the video by plastering copious quantities of grease onto the
plastic gears. In my never humble opinion, this is a bad idea. Many
plastic gears will be attacked by the solvents in the grease and
crumble. In particular, nylon gears are easily eaten by grease.

Clarification time. There are several plastic safe greases available.
White lithium grease and white grease with Teflon are both safe.
Silicon grease, molybdenum disulfide and many synthetic greases are
also safe. Soap will also work. What isn't plastic safe are greases
loaded with petroleum solvents, such as axle grease, engine oil, etc.

Incidentally, the official HP policy for their printers is to NOT use
any lubricants:
