Error 491 : Tray1 Error 492 : Tray2

The paper size displaying form of the custom mode is the same as above. In this state, Leisus I/F : corresponding bits of both LFTERR and LFTERR2 should be '0' (except MP T r ay).

Printing request is issued to an empty MP Tray. If it goes through a definite period of time (PU firmware holds time(3 sec)) after a user places paper, a printer will lift up the multipurpose tray, and will perform re-feeding. If a user pushes the ONLINE button before timeout, the printer perform also re-feeding,.

Error 490 : MP Tray

In this state, Leisus I/F : corresponding bits of both LFTERR and LFTERR2 should be '0'. Programmer's note: When the ONLINE button was pressed, the controller (CU) should send MPTPECLR command to the engine (PU). The engine would clear this state after receiving that command. This error is occurred, when the MP Tray is in the home position and the sensor "PE SNS2" cannot detect papers.
