Troubleshooting and error codes

The camera does not turn on. The battery is not installed properly. Check the orientation of the battery.
The battery power is low. Charge the battery.
The shutter cannot be released. There is no available space on the memory card. Insert a memory card with available space or delete unwanted images.
Data is being processed. Wait until processing is finished.
The lens aperture ring is set to a position other than A. Set the lens aperture ring to the A position or set [Using Aperture Ring] to [On] in the C6 menu. (p.118)
[AF Mode] is set to [Single AF] and the subject is not in focus. Set the focus method to w and adjust focus manually.
Autofocus does not work. The subject is difficult to focus on. v cannot work well for low contrast objects (the sky, white walls, etc.), dark colors, intricate designs, rapidly moving objects, or scenery shot through a window or a net-like pattern. Lock focus on another object located at the same distance as your subject, then aim at the subject and take an image. Alternatively, use w.
The subject is too close. Move away from the subject and take an image.
The flash does not discharge. [Flash Mode] is set to [Auto Flash Discharge]. When [Flash Mode] is set to [Auto Flash Discharge] in the A2 menu, the flash does not discharge if the subject is bright. Change the [Flash Mode] setting. (p.77)
The memory card is not recognized when the camera is connected to a computer. The [USB Setting] is set to [CD-ROM]. Set [USB Setting] to [MTP] in the D4 menu. (p.97)
Dust or dirt particles appear in images. The CMOS sensor is dirty or dusty. Activate [Dust Removal] from the D6 menu. The Dust Removal function can be activated every time the camera is turned on and off. Refer to "Sensor Cleaning" (p.124) if the problem persists.
Pixel defects such as bright spots and dark spots appear in the image. There are defective pixels in the CMOS sensor. Activate [Pixel Mapping] from the D6 menu. It takes about 30 seconds to correct the defective pixels, so be sure to install a fully charged battery.
