All-In-One is not communicating with the computer
Printing troubleshooting
All-In-One prints slowly
Note: If you scanned a photograph with your All-In-One, the 
file size could be too large to print with a selected 
scanning resolution higher than 300 dpi.
Disconnect and reconnect both ends of the USB cable (refer to 
your setup documentation for details).
Unplug the All-In-One from the electrical wall outlet, and then 
reconnect the power supply (refer to your setup documentation 
for details). Plug the All-In-One back in and turn the power back 
on.
Restart your computer. If problems still persist, see “Uninstalling 
and reinstalling the software” on page 25.
Close all programs not in use. The memory resources may be too 
low.
Make sure your Print Properties Quality/Speed setting is set on 
Normal or Quick Print. See page 5 for help.
Try printing a smaller file. If the memory resources are too low, 
you may not be able to print a very large file. Consider purchasing 
more memory.
