4 2nd Registration Sensor
1st Registration Sensor
The 1st registration sensor is attached to the left side of the carriage and moves side to
side with the carriage during printing.
The 1st registration sensor performs two important functions for print control:
Detects the leading edge of every sheet
Detects the width of the paper when the carriage and sensor pass horizontally over
the vertical edge of the paper as it feeds.
This is not automatic paper size detection. The paper size must be set with the
printer driver.
The printer will signal an alert if the detected size does not match the size
selected for the print job.
2nd Registration Sensor
The 2nd registration sensor is a photosensor mounted over the transport belt in the middle
of the transport belt. The 2nd registration sensor detects the leading and trailing edge of
each sheet during high speed printing. The printer uses this information for print control
timing.
