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.
