My Nikon D7100 will not take a picture. I’ve tried changing lenses and removing the battery, but the only clue I can find is that “For” is blinking on the screen. What does this mean, and how can I fix it?

If you see For flashing when you first turn on the camera it is an error message. See page 334 of your Nikon D7100 User Manual where it appears in a list of error messages.

Problem: Memory card has not been formatted for use in camera.
Solution: Format memory card or insert new memory card

It is telling you that there is currently no memory card in the camera formatted properly for use in your camera. You need to format the memory card using the camera to format it so that the card will be properly formatted for use in your camera. You may also get this message if there are no memory cards in the camera or if only one memory card is inserted into slot #2 when there is no memory card inserted into slot #1. Page 30 of your Nikon D7100 User Manual instructs to always use slot #1 when only using one memory card in the camera.

Page 32 of your Nikon D7100 User Manual tells you how to format the card:

On the Nikon D7100, a blinking “For” message usually means the memory card is not formatted for use in the camera. It can also appear if no card is inserted, or if a card is only in slot 2 while slot 1 is empty.

Try this:

  1. Make sure a memory card is inserted in slot 1.
  2. If the card has files from another device or was formatted elsewhere, format it in the D7100.
  3. If formatting doesn’t help, try a different memory card.

Formatting in the camera is the best way to prepare the card so the D7100 can use it properly. Keep in mind that formatting will erase the card’s contents, so save any important images first if possible.

The D7100 manual lists this as a memory-card formatting error.
