Check1 Make sure that paper is loaded.
Loading Paper
Check2 Make sure of the following when you load paper.
•
When loading two or more sheets of paper, flip through the paper before loading. In addition, when you load
paper with some paper remaining in the cassette, flip through the remaining paper and the newly loaded
paper before loading.
•
When loading two or more sheets of paper, align the edges of the sheets before loading.
•
When loading two or more sheets of paper, make sure that the paper stack does not exceed the paper load
limit.
However, proper feeding of paper may not be possible at this maximum capacity depending on the type of
paper or environmental conditions (either very high or low temperature and humidity). In such cases, reduce
the sheets of paper you load at a time to less than half of the paper load limit.
•
Always load the paper in portrait orientation, regardless of the printing orientation.
Loading Paper
Important
•
When loading paper in the cassette, slide the paper guide on the front side to align with the
corresponding mark of page size. Load the paper with the print side facing DOWN, load the paper
stack in the center of the cassette, then slide the paper guides to align with the both edges of the paper

							Copying/Printing Stops Before It Is Completed
Check1 Is the paper loaded?
Make sure that paper is loaded.
If the machine has run out of paper, load paper.
Check2  Do the printing documents have lots of photographs or illustrations?
As printing large data such as photos or graphics takes time for the machine and the computer to process, the machine may appear to have stopped operating.
In addition, when printing data that uses a large amount of ink continuously on plain paper, the machine maypause 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.
Check3  Has the machine been printing continuously for a long period?
If the machine has been printing continuously for a long time, the print head or other parts around it may overheat. The machine may stop printing at a line break for a period of time and then resume printing.
In this case, wait for a while without operation. If the printing still does not resume, interrupt your print session at
a convenient time and turn the machine off for at least 15 minutes.
Caution
•
The print head and the surrounding area can become extremely hot inside the machine. Never touch the print head or nearby components.
