4.5.3 PRE-STACK MECHANISM
This feature is available only when using A4 L, LT L, and B5 L.
During stapling, the main machine must wait. This mechanism reduces the wait by
holding the first two sheets of a job while the previous job is still being stapled. It
only works during the second and subsequent sets of a multi-set print job.
The pre-stack junction gate solenoid [A] switches on after the first sheet activates
the entrance sensor. This directs the sheet to the pre-stack tray [B].
The pre-stack feed roller [C] stops for a specified time after the trailing edge of the
paper has passed through the entrance sensor and stops the paper from leaving
the pre-stack tray.
At the same time, the pre-stack junction gate solenoid switches off, and the second
sheet is sent to the paper guide [D]. The pre-stack feed roller (controlled by the
pre-stack motor) starts to rotate again for a specified time after the trailing edge of
the second page has been passed through the entrance sensor, and then both
sheets are sent to the stapler tray together.
