# Troubleshooting "Initialize Cameras before capturing images" error on the MiSeq

Users may encounter an "Initialize Cameras before capturing images" error message during the first cycles of a MiSeq runs. This error may occur if the previous run on the instrument ended early due to a communications error that caused the cameras to shut down.

An example of this type of error is an FPGA error, which can be investigated by searching for Knowledge Base article **Troubleshooting FPGA Timeout Errors on the MiSeq**. If the user did not power cycle after such an error, this can cause an "Initialize Cameras before capturing images" error to occur.

**Troubleshooting steps:**

* Power cycle the instrument in order to re-initialize the cameras, power cycle the instrument.
  * For further information, search for Knowledge Base articles **How to shut down or power cycle the MiSeq** and **How To Power Cycle the MiSeq Video**.
* Check D:\ drive space; if full delete older data (after backing up to an off-instrument location).
  * For further information, search for Knowledge Base articles **Run folder sizes and Disk Space on the MiSeq** and **Troubleshooting Free Disk Space errors during Pre-run Checks on MiSeq.**

If the instrument fails to initialize or the error persists, contact [Illumina Technical Support](https://www.illumina.com/company/contact-us.html#/united-states/technical-support).
