Hi!

It's in there, but you were probably looking at the B064 section. The B140/B246/D052 is further down in the manual, which has this.....
220 Laser synchronization detection error
The 1st laser synchronization detection
unit could not detect the line
synchronization signal (DETP0) within
500 ms while the polygon mirror motor
was operating at normal speed.
NOTE: The unit polls for the signal
every 50 ms. This SC is issued after the
10th attempt fails to detect the signal.
B246/D052
• Laser synchronization board
connector loose, broken, defective
• Laser synchronization detection
board is not installed correctly (out
of alignment)
• Laser synchronization board
defective
• IPU defective
So many thanks for your help
