• If you set the product to save received faxes on a USB device, connect the selected USB device
containing the save fax folder to the product. Once the faxes are saved on the USB device, they are
deleted from the product's memory.
Note: Make sure the USB device has enough available memory and is not write protected.
• If the memory is full, try the following:
• Send a monochrome fax using the direct sending feature
• Send your faxes in smaller batches
• If the product cannot print a received fax due to a product error, such as a paper jam, the memory full
error may appear. Clear any product errors, then ask the sender to resend the fax.
