When a printer “grabs” a sheet of paper, a device called a separator helps the printer pick up only the top sheet. The separator isn’t foolproof though.

One reason the separator might not work is if the sheets of paper stick to each other a little more than normal. This can happen for a number of reasons, but the solution is the same – try different paper. Start by trying another stack from the same paper supply. If that doesn’t work, try paper from another ream or even another brand.

Another reason the separator might not do its job is if it has worn out. If this is the problem, the separator will need to be replaced. In an inexpensive printer, your best bet might be to replace the printer. In more expensive printers, like laser printers, you can often buy what’s called a “maintenance kit” that will include a new separator along with some other printer parts that tend to wear out after a lot of use.

If your printer is picking up multiple pieces of paper most of the time, even after trying different paper, you’re probably going to need to replace the separator.

Remember to keep your paper stored at about the same temperature and humidity that you’d run your computer and printer at in your home or office. Extreme temperature, and especially extreme humidity, can damage printer paper and could cause this problem.
