							Paper Does Not Feed Properly/"No Paper" Error Occurs
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 stack.
Loading Paper
Check3  Check to see if the paper you are printing on is not too thick or curled.
Media Types You Cannot Use
Check4  Make sure of the following when you load Hagakis or envelopes.

If a Hagaki is curled, it may not feed properly even though the paper stack does not exceed the paper load
limit.
Load Hagakis with a zip code column toward the far end of the cassette 1.
•
When printing on envelopes, refer to Loading Paper , and prepare the envelopes before printing.
485

loaded paper.
Check6  Clean the paper feed roller.
Cleaning the Paper Feed Roller
Note
•
Cleaning the paper feed roller will wear the roller, so perform this procedure only when necessary.
Check7 If two or more sheets of paper feed from the cassette at once, clean the inside
of the cassette.
For information on cleaning the inside of the cassette, refer to 
Cleaning the Pad in the Cassette .
If you cannot remove the paper or the paper tears inside the printer, or if the paper jam error continues after
removing the paper, contact the service center.

							Printing Stops Before It Is Completed
Check1 Is the paper loaded?
Make sure that paper is loaded.
If the printer 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 printer and the computer to process, the
printer may appear to have stopped operating.
In addition, when printing data that uses a large amount 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.
Check3  Has the printer been printing continuously for a long period?
If the printer has been printing continuously for a long time, the print head or other parts around it may overheat.
The printer 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 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.

							Problems with Printing Quality
Print Results Not Satisfactory
Ink Is Not Ejected
489
 
						

							Print Results Not Satisfactory
If the print result is not satisfactory due to white streaks, misaligned lines, or uneven colors, confirm the
paper and print quality settings first.
Check1  Do the page size and media type settings match the size and type of the loaded
paper?
When these settings are incorrect, you cannot obtain a proper print result. If you are printing a photograph or an illustration, incorrect paper type settings may reduce the quality of the
printout color.
Also, if you print with an incorrect paper type setting, the printed surface may be scratched.
Confirm the page size and media type settings using the printer driver.
Printing with Easy Setup
Check2  Make sure that the appropriate print quality is selected using the printer driver.
Select a print quality option suitable for the paper and image for printing. If you notice blurs or uneven colors,
increase the print quality setting and try printing again.
You can confirm the print quality setting using the printer driver.
