Why does the front panel display LOW PAPER when there is paper in the cassette tray?
LOW PAPER is displayed when there are fewer than 100 sheets (using 75 gsm) in the cassette tray. • It does not prevent printing, but you should keep the cassette tray at least 3/4 full or turn off the SOFT ERROR detection. • SOFT ERROR on Series 4/5 is located under the UTILITY menu on the front panel. • SOFT ERROR on Series 3 is located under the MISC menu on the front panel.
