imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+
At double-sided printing, in order to correct the displacement of the image position of the second side in the main scanning direction, side registration detection is
performed and thus the laser write start position is corrected.

[4] Side registration motor (M21)
Detection of the home position of the side registration sensor (PS25) is performed at power-on, open/close of the front cover, open/close of the right upper cover,
open/close of the right lower cover, recovery from the power-saving function, and end of print, and then brought to the 13x19 paper detection position.
When the paper fed to the duplexing left feeding assembly reaches the duplexing left sensor (PS19), side registration motor (M21) is turned ON and then the side
registration sensor (PS25) detects the edge of paper.
Detection start position is set by recognizing the cassette size and the slide guide width of the manual feed tray at the start of copying so that the paper edge is
positioned to feed ideally (In case of A4 paper, 165 mm from the center of the unit).
