Paper Size Sensing Lower Cassette
The operator must set the appropriate paper size for the Lower Cassette using a dial which, in turn, activates switches on the cassette base. This setting is sent to the DC Controller on the serial data bus (SLI). The printer posts a 41.3 SERVICE error if the media is different from that selected with the switch.
To verify proper operation of the LC (Tray 3) switches, lock out the MP (Tray 1) and PC (Tray 2) trays (in the Config Menu) and perform the same test with Lower Cassette switches as was done for the PC tray (Tray 2) switches.
