Coupling Conveyance; Sub Tray Conveyance - Develop ineo+ 6500 Service Manual

6. CONVEYANCE SECTION
H. Stacker tray up down control
The detection of the upper surface of paper loaded on the stacker tray is made by the paper empty sensor (PS6)
through the paper press arm /3. When PS6 is turned off by loading paper that has been exited, the stacker tray
up down motor (M1) turns on to lower the stacker tray down to the position at which PS6 turns on. The stacker
tray is thus held at a fixed height when paper is being exited.
The number of sheets of paper loaded on the stacker tray is detected by the 2000 sheets stacked sensor
(PS13) and the 5,000 sheets stacked sensor (PS14) provided on the up down path of the stacker tray and dis-
played on the operation panel. (3,000 sheets stacked detection is made by the main unit.)
When the hand cart once pulled out is put back to its original position, the stacker tray moves up to return to its
home position. If the paper detection sensor (PS19) detects that papers are loaded on the stacker tray, the tray
stops moving up in order to prevent the alignment plate from being damaged by the uplifted paper.
I. Hand cart detection mechanism
The set condition of the hand cart is detected by the hand cart set switch (RS1). And the set condition of the
stacker tray is detected by checking to see if the light from the stacker tray set LED (LED1) gets to the stacker
tray set sensor (PS1).

Coupling conveyance

In coupling mode, paper is conveyed to the device connected to the subsequent stage of the LS through the
coupling conveyance section.
A. Line speed switching
When paper is conveyed from the main body, the conveyance motor (M2) at the entrance conveyance section is
rotated at the same speed as the conveyance speed of the main body. When paper is conveyed to the LS, the
speed of rotation of M2 is increased up to 1,000 mm/s to convey paper.
6.3.3

Sub tray conveyance

In sub tray mode, paper is exited into the sub tray.

B. Paper full control
When the number of the sheets of paper discharged on the sub-tray gets to 200, the sub tray full sensor (PS9)
turns on to give indication of "paper full" on the operation panel.
