General Problems
THE ORIGINAL SIZE IS NOT AUTOMATICALLY 
SELECTED OR THE WRONG SIZE IS SELECTED
Check Solution
Is the original curled or folded? ■ Straighten the original. 
The correct original size cannot be detected if the original is curled or folded.
Did you place an original smaller than 
A5 (5-1/2" x 8-1/2") size?
■ Select the original size manually. 
Original sizes smaller than A5 (5-1/2" x 8-1/2") cannot be detected. When 
scanning a small original on the document glass, it is convenient to place a blank 
sheet of paper on top of the original which is the same size (A4 (8-1/2" x 11"), B5 
(8-1/2" x 11"R), etc.) as the paper that you wish to use for printing.
Is an original of the A5 (5-1/2" × 8-1/2") 
size set to landscape (A5R size)?
■ If an original of the A5 (5-1/2" × 8-1/2") size is set to landscape (A5R size), it is 
not detected automatically.
Is the document feeder sensor dirty? 
(MX-M3071/MX-M3071S/MX-M3571/ 
MX-M3571S/MX-M4071/MX-M4071S/ 
MX-M5071/MX-M5071S/MX-M6071/ 
MX-M6071S)
■ Wipe the sensor clean using a damp cloth or a wet tissue.
THE DISPLAYED BYPASS TRAY PAPER SIZE IS 
NOT CORRECT
Check Solution
Do the bypass tray guides match the 
width of the loaded paper?
■ Set the bypass tray guides to the width of the paper. 
When loading paper in the bypass tray, be sure to pull out the extension guide to 
enable the paper size to be detected correctly.
