USB Memory
USB memory is a type of simple, highly portable flash memory that plugs
into the USB memory slot. Files stored in USB memory can be printed by
plugging the USB memory into the printer and then specifying the desired
file names from the operation panel.
The operation panel displays the names of PDF, TIFF, JPEG and XPS
files.
Up to 100 files can be printed from USB memory. Files with names
consisting of up to 99 single-byte alphanumeric characters can be
printed. However, because the message display will only show 12
characters, files with 13 or more characters cannot be identified on the
message display.
Any double-byte characters included in a file name appear as corrupted
text in the message display. Also, when the file is printed an error
message appears and printing fails.
For information on printing PDF files stored in USB memory, refer to USB
Memory (USB memory selection) on page 4-16.
For information on supported USB memory devices, contact your service
technician.
