CompactFlash
If the Resume LED does not blink after inserting the CompactFlash (CF) card,
this means there are no DPOF files created on the CF card. To print from the
CF card, you need to specify your print settings in a DPOF file so that the printer
can print out images specified in the DPOF file. See
Printing digital camera
photographs .
Step 4: Check the printer selection
Make sure your printer is selected as the current or default printer. If you are
running Windows, make sure
Pause Printing is not selected. For Macintosh,
make sure Stop Print Queue is not selected.
Step 5: Check the print settings
Make sure the print settings (such as paper type, paper size, margins, and
color) in the printer driver are correct.
For Windows, print settings are typically available by selecting File > Print >
Properties in an application. For Macintosh, they are typically available by
selecting File > Page Setup in an application.
Step 6: Check the print media
Make sure media is loaded correctly in the input tray or card slot with the print
side up and that the media is not jammed in the printer.
For information about loading media, see Selecting print media . For information
about clearing and preventing jams, refer to Solving media feed problems .
Step 7: Check the LEDs
If any LED turns on or blinks, see LED Reference for the list of printer LED
combinations you may encounter, what they indicate and how to solve the
problem.
Step 8: Check the print cartridges
Make sure the print cartridges are properly installed and that the protective film
covering the ink nozzles has been removed. Make sure the print cartridges are
not empty.
If one print cartridge is empty, you can still print with the other print cartridge.
