Understanding the error messages

Once you are familiar with the types of errors that can occur while you print data from the USB Flash memory drive with Direct Print, you can easily identify and troubleshoot any problems.

This message will appear if you are working with images that are too large for the machine’s memory.
Unusable Device
This message will appear if you connect an incompatible or broken device to the USB direct interface. To clear the error, unplug the device from the USB direct interface.
