Composition/Operation
D. Retraction mechanism
• In addition to the change of the pressure position of the 1st image transfer roller, the
machine moves the color retraction roller or the K retraction roller up and down to change
the position of the image transfer on the surface of the transfer belt depending on the
print mode of each job.
• Similar to the pressure position change mechanism, the retraction mechanism changes
the position at which the pressure cam stops in order to move the retraction lever so that
the retraction roller moves up and down.
(1) Color retraction roller
• The color retraction roller is driven by the color cam.
(2) K retraction roller
• The K retraction roller is driven by the K cam.
