Description: The locking of the paper lift motor /2 (M20) is detected. When M20 is ON, an error detection signal of the M20 is detected.
Causes: Paper lift motor /2 (M20) Printer control board (PRCB) Upper limit sensor /2 (PS21) DC power supply /2 (DCPS2) Loose connection Tray rear end restriction plate misaligned Paper improperly loaded Tray 2
Code: SC18-21#
Description: When the upper limit sensor /2 (PS21) is OFF, PS21 does not turn ON within a specified period of time after the paper lift motor / 2 (M20) turns ON for lifting operation. And at this time, an error detection signal (24V cut off) is detected.
