Mp c4501 sc226 continuation...

[SDtech619]

Hey all,
So i thought i was done seeing this issue but apparently it has reared its ugly head like the poltergeist movie. I replaced the entire laser unit...I'm thinking firmware or BICU next. Suggestions? Thanks in advance!

Always update the firmware, this code (sc226) is for the Cyan, could possibly be BICU.

226

Laser synchronizing detection error: start position [C]: LD0

The laser synchronizing detection signal for the start position of the LDB [K], [Y], [M], [C] is not output for two seconds after LDB unit turns on while the polygon motor is rotating normally.

Disconnected cable from the laser synchronizing detection unit or defective connection Defective laser synchronizing detector Defective LDB Defective BICU

Check the connectors. Replace the laser-synchronizing detector. Replace the LDB. Replace the BICU.

From Goose's Guide:

D088/D089	SC 226	Laser Sync detect error Cyan - replace laser assy #D0891851
D088/D089	SC 226	Laser Sync detect error Cyan - check connections, laser to BICU
D088/D089	SC 226	Laser Sync detect error Cyan - replace BICU

I would start with the cable from the laser unit to the BICU. Less expensive than a new BICU.

UPDATE 6/3/16

So I ended up replacing the BICU...worked for a couple weeks annnnnnnd we are back to the same error. I will be trying to update firmware again and see if that fixes it. Tech support confidently advised it was the board...stay tuned. Thx for the replies!
