It might sound like a strange question, but I noticed that my printer is folding paper. So I would like diagnose it, whether it's because of cartridge or the problem is somewhere else.

If I could put paper through printer without cartridge inside, and it still would be folded then it would clearly be the problem with printer itself.

Printer is HP M125nw. Basically I would like to make sure, that folding is not because of cartridge.


Question: How can toddlers expend seemingly boundless energy when they eat so little?
Answer: Just to add to the answer from @buzrw:

Using data from here and here I have estimated recommended calorie intake per kg for a 2 yr old and for an adult. I've used figures for males and assumed 70 kg for the adult weight which is the "international standard man":


  toddler: 120 Cal kg-1
  
  adult: 40 Cal kg-1


So yes, the energy intake of toddlers is higher than that of an adult.
