Vertical conveyance control
In the vertical conveyance section, paper is
fed vertically by transmitting the drive force
of M1 (paper feed) to the vertical
conveyance roller (upper) and vertical
conveyance roller (lower) via MC11 (vertical
conveyance MC/1) and MC12 (vertical
conveyance MC/2). The above parts are
controlled by PRCB (printer control board).
Related signals are PS25 to PS27 (vertical
conveyance/1 to /3) and PS29 (vertical
conveyance door open/close).
1 Operation
Paper fed from Tray 2 is then fed to the
second paper feed unit directly without
passing through vertical conveyance
rollers. When paper is fed from Tray 3 or
4, PS26 (vertical conveyance/2) is used to
feed paper to the standby position. When
PS26 is turned off by the preceding paper,
MC11 and MC12 (vertical conveyance
MC/1 and MC/2) are turned on and the
paper fed from Tray 3 or 4 is fed to the
standby position (where PS26 was turned
on) by the drive force of M1 (paper feed).
MC11 and MC12 are turned on after lapse
of the specified time from restart of
