Cause
The paper setting specified at the time of printing is different from the paper information registered in the printer.
What to Do
Press the printer's Stop button to cancel printing.
Match the paper loaded in the rear tray with the paper size registered on the printer using the printer's Paper Select button.
In the paper settings specified at the time of printing, specify the paper information registered in the printer, and retry printing.
If the paper size loaded in the rear tray is larger than the paper size set at the printer driver, you can continue printing without changing the paper size settings. Press the printer's OK button.
Learn about the paper sizes that can be registered in the printer using the printer's Paper Select button.
You can disable the function to prevent printing error. 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. This can be adjusted from the operation panel of the printer, a Windows PC, or a Mac.
