G031D526.WMF
The registration sensor [A] is just after the relay roller [B]. However, this machine
has no registration roller.
A certain time after the paper leading edge activates the registration sensor, the
CPU starts to write the latent image on the drum.
The registration sensor is also used for paper misfeed detection.
