Cause
Paper size settings in the printer driver don't match the paper size registered in the printer.
What to Do
Press the printer's Stop button to cancel printing.
Check if the size of the paper loaded in the rear tray matches the paper size registered in the printer using the printer's Paper Select button.
After checking the paper settings set at the printer driver, try printing again.
If the paper size loaded in the rear tray is larger than the paper size set at the printer driver, you can continue the printing without changing the paper size settings. Press the printer's OK button.
You can disable the function to prevent printing errors from a Windows PC or a Mac. When this function is disabled, the printer uses the paper settings for printing onto the paper in the rear tray regardless of whether or not the paper matches these settings.
