If the SPE cartridges are not installed or incorrectly installed, the instrument interface displays, Could not find cartridge.

To troubleshoot this error, check if the SPE tray is properly loaded and installed. Use the image in the kit loading workflow on the instrument interface as reference.

Cartridges must be filled from the back left corner (38 cartridges for LF36, 18 for LF16, 12 for TMTpro, 18 for TMT).
