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.

problem, turn off the printer, unplug the power adapter from the printer, wait 
a few seconds, and reconnect the power.

Check the status of the print cartridges
If you are printing with a single print cartridge, the print speed may be 
slower than normal. See Single-cartridge printing mode.

If less than 80 percent of the computer resources are available, printing 
can be significantly slower. To make more computer resources available, 
close all unused applications and resend your print job. If necessary, 
restart your system and then resend your print job.

smear.

Check that the media is loaded print-side up.

Check that the correct media type is selected in the printer driver.
