Machine Moves But Ink Is Not Ejected
Paper Does Not Feed Properly
CauseAction
Print Head nozzles are clogged. See “When Printing Becomes Faint or Colors Are Incorrect” on page 113 and 
perform any necessary maintenance operation.
Ink tank is empty. See “An Error Message Is Displayed on the LCD” on page 133 to identify the ink  error, and then take the appropriate action depending on the error condition.
CauseAction
Printing on inappropriate type of paper. Check to see if the paper you are printing on is not too thick or curled.
See “Paper Handling” on page 21 to make sure that the paper you are using is 
suitable.
If the paper is curled, see “Paper is curled.” on page 144 to correct paper curl.
Paper Feed Roller is dirty. Clean the Paper Feed Roller. Cleaning the Paper Feed Roller will wear the  roller, so perform this procedure only when necessary.
For details on cleaning, see “Cleaning the Paper Feed Roller (Roller Cleaning)” 
on page 125.
Paper not loaded properly. Make sure of the following when you load paper in the machine. zWhen loading two or more sheets of paper, align the edges of the sheets 
before loading.
z Always load the paper in portrait orientation, either in the Rear Tray or 
Cassette, regardless of the printing orientation.
z When loading paper in the Rear Tray, load the paper with the print side facing 
UP. Align the right edge of the paper stack against the Cover Guide and slide 
the Paper Guide so that it just touches the left edge of the stack.
z When loading paper in the Cassette, load the paper with the print side facing 
DOWN. Align the right edge of the paper stack against the right edge of the 
Cassette and slide the Paper Guides against the left and bottom edges of the 
stack.
z When loading paper, make sure that the paper is not set over the Load Limit 
Mark.
For details on loading paper, see “Loading Paper” on page 25.
Too much paper loaded. 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 around half of 
the paper load limit.
For details on loading paper, see “Loading Paper” on page 25.
Foreign object in the Rear Tray or 
Cassette. Make sure that there are no foreign objects in the Rear Tray or Cassette.
Envelopes not prepared or loaded 
properly. When printing on envelopes, load them in the machine in portrait orientation. If 
the envelopes are placed in landscape orientation, they will not feed properly.
For details on loading envelopes, see “Loading Envelopes” on page 29.
