Ros Sos M Length - Xerox DocuColor 2240 Service Manual

6-381 ROS SOS M Length

The interval of the ROS Start-of-Scan (M) signals exceeds the specified value.
Procedure
+5VDC is measured between the MCU PWB P/J401-B19 (+) and ground (-).
Y N
Replace the MCU PWB (PL 13.1).
Refer to Figure 1 and check the wire between the SOS PWB (M) P/J517-2 and the MCU PWB
P/J401-B12 for an open circuit.
Check the wires between P/J528 and the MCU PWB
If no problems are found, replace the ROS Assembly
If the problem continues, replace the MCU PWB

6-382 ROS SOS C Length
The interval of the ROS Start-of-Scan (C) signals exceeds the specified value.
Procedure
+5VDC is measured between the MCU PWB P/J401-A1 (+) and ground (-).
Y N
Replace the MCU PWB (PL 13.1).
Refer to Figure 1 and check the wire between the SOS PWB (C) P/J514-2 and the MCU PWB
P/J401-B9 for an open circuit.
Check the wires between P/J527 and the MCU PWB
If no problems are found, replace the ROS Assembly
If the problem continues, replace the MCU PWB
