Related Models: MFC-J690DW/MFC-J895DW
USB flash drive support is available only for certain models (MFC-J690DW/MFC-J895DW).
Your machine is designed to be compatible with modern digital camera image files, memory cards and USB flash
drives. Read the points below to avoid errors:
• The image file extension must be .JPG (other image file extensions like .JPEG, .TIF, .GIF and so on will not
be recognized).
• Direct photo printing must be performed separately from photo printing operations using the computer.
(Simultaneous operation is not available.)
• The machine can read up to 999 files
1
on a memory card or USB flash drive.
Be aware of the following:
• When printing an index or image, the machine will print all the valid images, even if one or more images have
been corrupted. Corrupted images will not be printed.
• (Memory card users)
Your machine is designed to read memory cards that have been formatted by a digital camera.
When a digital camera formats a memory card, it creates a special folder into which it copies image data. If
you must use your computer to modify the image data stored on a memory card, we recommend that you do
not modify the folder structure created by the digital camera. When saving new or modified image files to the
memory card, we also recommend you use the same folder your digital camera uses. If the data is not saved
to the same folder, the machine may not be able to read the file or print the image.
• (USB flash drive users)
Your machine supports USB flash drives that have been formatted by Windows
®
