Solve walk-up USB printing problems
● The USB Flash Drive menu does not open when you insert the USB accessory
● The file does not print from the USB storage accessory
● The file that you want to print is not listed in the USB Flash Drive menu
The USB Flash Drive menu does not open when you insert the USB accessory
1. You might be using a USB storage accessory or a file system that this product does not support. Save
the files on a standard USB storage accessory that uses File Allocation Table (FAT) file systems. The
product supports FAT12, FAT16, and FAT32 USB storage accessories.
2. If another menu is already open, close that menu and then reinsert the USB storage accessory.
3. The USB storage accessory might have multiple partitions. (Some USB storage accessory manufacturers
install software on the accessory that creates partitions, similar to a CD.) Reformat the USB storage
accessory to remove the partitions, or use a different USB storage accessory.
4. The USB storage accessory might require more power than the product can provide.
a. Remove the USB storage accessory.
b. Turn the product off and then on.
c. Use a USB storage accessory that has its own power supply or that requires less power.
5. The USB storage accessory might not be functioning correctly.
a. Remove the USB storage accessory.
b. Turn the product off and then on.
c. Try printing from another USB storage accessory.
The file does not print from the USB storage accessory
1. Make sure paper is in the tray.
2. Check the control panel for messages. If paper is jammed in the product, clear the jam.
The file that you want to print is not listed in the USB Flash Drive menu
1. You might be trying to print a file type that the USB printing feature does not support. The product
supports .PDF and .JPEG file types.
2. You might have too many files in a single folder on the USB storage accessory. Reduce the number of
files in the folder by moving them to subfolders.
3. You might be using a character set for the file name that the product does not support. In this case, the
product replaces the file names with characters from a different character set. Rename the files using
ASCII characters.
