In this comprehensive guide, we will delve into the various reasons why your Nikon D90 may be displaying the “Err” message and provide practical solutions to resolve it.
Lens Communication Error
One of the most common causes of the “Err” message is a communication error between the camera body and the lens. This can occur due to dirty or misaligned contacts on either the lens or the camera body. To resolve this issue:
- Clean the lens and camera contacts: Use a soft, clean cloth or lens cleaning solution to gently wipe the electrical contacts on both the lens and the camera body.
- Ensure proper lens mounting: Make sure the lens is securely mounted on the camera body and locked into place.
- Try a different lens: If possible, try using a different lens to determine if the issue is with the lens or the camera body.
Shutter or Mirror Malfunction
Another potential cause of the “Err” message is a malfunctioning shutter or mirror. These mechanical components can become damaged or misaligned, preventing the camera from operating correctly. To address this issue:
- Check the shutter: Inspect the shutter curtains for any damage or obstruction. Gently clean the shutter mechanism using a soft brush or compressed air.
- Examine the mirror: Look for any misalignment or damage to the mirror. If necessary, have the mirror professionally adjusted or replaced.
Memory Card Error
A faulty or incompatible memory card can also trigger the “Err” message. To troubleshoot this issue:
- Format the memory card: Insert the memory card into your computer and format it using the appropriate file system (FAT32 for cards up to 32GB, exFAT for cards larger than 32GB).
- Try a different memory card: Use a known-good memory card to determine if the issue is with the card or the camera.
- Clean the memory card contacts: Use a soft cloth to gently clean the electrical contacts on the memory card.
Battery Issue
A weak or malfunctioning battery can also cause the “Err” message. To resolve this issue:
- Replace the batteries: Insert fresh or fully charged batteries into the camera.
- Clean the battery contacts: Use a soft cloth to gently clean the electrical contacts on the batteries and in the battery compartment.
- Try a different battery type: Consider using a different type of battery, such as alkaline or lithium-ion, to determine if the issue is battery-related.
Firmware Bug
In rare cases, the “Err” message can be caused by a firmware bug. To address this issue:
- Check for firmware updates: Visit the Nikon website to check if there are any firmware updates available for your D90.
- Update the firmware: If an update is available, download and install it on your camera following the manufacturer’s instructions.
Other Possible Causes
If the above solutions do not resolve the “Err” message, it could be caused by other factors, such as:
- Damaged camera body: Physical damage to the camera body, such as a cracked screen or a loose connection, can trigger the error message.
- Internal hardware failure: A more serious issue, such as a malfunctioning sensor or circuit board, may require professional repair.
- Software glitch: A temporary software glitch can sometimes cause the camera to display the “Err” message. Restarting the camera or removing and reinserting the battery may resolve the issue.

If you have tried all of the troubleshooting steps outlined above and the “Err” message persists, it is recommended to seek professional help. A qualified camera repair technician can diagnose the underlying issue and provide a solution.
