Printing Stops Before It Is Completed
Check 1: Is the Inner Cover opened while printing o n paper?
Close the Inner Cover and press the 
RESUME/CANCEL button on the printer.
A page of print data being sent at the time of the  error will be erased, so print that page again.
Check 2: Has the printer been printing continuously  for a long period?
If the printer has been printing continuously for a lo ng time, the Print Head may overheat. To protect
the Print Head, the printer may stop printing at a  line break for a period of time and then resume
printing. 
In this case, interrupt your print session at a convenient  time and turn the printer off for at least 15
minutes.
Additionally, if the printer has been printing graphics or photos with intense colors continuously ove r
a period of time, the printer may stop printing to p rotect the Print Head. In this case, printing will not
resume automatically. Turn the printer off for at least  15 minutes.
Caution
The Print Head and the surrounding area can become  extremely hot inside the printer. Never
touch the Print Head or nearby components.
Check 3: Is the paper loaded? 
Make sure that paper is loaded in the Rear Tray or  Cassette.
If the printer has run out of paper, load paper.
Check 4: Do the printing documents have lots of pho tographs or
illustrations? 
As printing large data such as photos or graphics t akes time for the printer and the computer to
process, the printer may appear to have stopped ope rating.
In addition, when printing data that uses a large a mount of ink continuously on plain paper, the
printer may pause temporarily. In either case, wait  until the process is complete.
Note
If you are printing a document with a large printing area or printing multiple copies of a
document, printing may pause to allow the ink to dry.
