The printer is really slow. Your computer may have less than
minimum system requirements.
1
Check the amount of RAM and processor speed in your computer. See
“System Requirements” on page 85.
2
Free up some space on your hard drive. Having less than 100MB of free
space on your computer’s hard drive can mean longer processing times.
Too many software programs may
be running at the same time.
Close all unnecessary software programs.
