<h3>What happened?</h3>
<p>The printer is displaying the message: <strong>The printer has booted from an alternative slot due to failed boot attempts using the primary slot.</strong> Update the printer with up-to-date firmware ASAP to recover the primary slot. This usually happens after a failed update, or due to a hardware failure. Printer settings may have been reset.</p>
<p>Error name: Boot slot changed&nbsp;</p>
<p>Error code: #10601</p>
<h3>How to fix it?</h3>
<p>Try to flash the firmware again. Try to avoid using OTA flashing as your network can be a factor. If it persists, it may indicate an issue with the on-board eMMC storage and the board may need to be replaced. If so, please contact support.</p>
