Cause
The paper setting specified at the time of printing is different from the paper information registered in the printer.
To disable notifications for this error, disable the function to detect paper setting mismatch.
What to Do
Press the printer's Stop button to cancel printing.
In the paper settings specified at the time of printing, specify the paper information registered in the printer, and retry printing.
To continue printing without changing printer settings, press the printer's OK button. This may cause the printed surface to be smudged or dirty.
