A problem I've often had when loading paper into a printer is when **two or more sheets get stuck together**. This is unnoticeable when you put a big stack of paper into the printing tray, but becomes a real pain when you actually start to print. Especially if you're trying to print two-sided - two sheets come out with only one side of each printed on - but even if you're not, a sheet twice as thick as normal often causes a paper jam.

**Are there any good ways to avoid this problem?**  

Note: I'm not talking about dealing with a paper jam after the fact, but about what to do with the paper before loading it into the printer in order to make sure sheets don't stick together in the first place.

"*What have I tried?*" I searched on Google about this problem, but all the links I found ([one](http://ugp01.c-ij.com/ij/webmanual/ErrorCode/MX450%20series/EN/ERR/ERR_Other0100.html), [two](http://www.computerhope.com/issues/ch000980.htm), [three](https://www.youtube.com/watch?v=BdFvyDZmiFI), [four](https://nealpoole.com/blog/2011/03/clearing-a-fake-paper-jam-in-an-hp-printer/), [five](http://www.canon.co.uk/support/consumer_products/videos/mx455/)) were about unjamming a jammed printer, rather than stopping it from jamming in the first place. So I came to the trusty life-hackers of Stack Exchange!
