Memory Card Problems

Make sure that the type of memory card you are using can be used in the printer.
For more information, see
Insert only one memory card at a time.
Do not remove the memory card or touch the printer in the area of the memory card
while the light is blinking.
The blinking light indicates the printer is communicating with the memory card. Communication errors
might occur if you remove the memory card or touch the area near the memory card while the light is
blinking.
Do not insert more than one memory card or USB key at the same time.
Make sure the memory card is properly inserted.
Insert the memory card until it stops. The printer will not read the contents of the memory card if it is not
properly inserted into the memory card slot.
When printing images from a memory card, make sure the file format of the images is
supported by the printer.
Only images in JPG and a limited set of TIFF formats can be printed directly from the memory card. If you
want to print photos stored on the memory card in a different file format, the photos must be transferred
to your computer before printing.
Ensure the printer is not connected to a PictBridge-enabled camera.
