PRE-STACK MECHANISM
2.2 PRE-STACK MECHANISM
This mechanism improves productivity in staple mode and shift mode.
During stapling, the copier has to 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 copy job.
