6 MECHANICAL OPERATIONS
6-1. Vertical Transport Drive Mechanism
1. Vertical Transport Drive Operation
•
The Vertical Transport Roller is driven by LCC Transport Motor HMOT.
•
The driving force of HMOT is transmitted via a gear train and Registration Clutch RCL to the Vertical Transport Roller which feeds the paper from Lift 1 or 2 to the copier.
•
Because of the long paper path from Lift 2 involved, skew tends to occur in the paper fed from Lift 2. Registration Clutch RCL forms a loop in the paper between the Separator Roll and Vertical Transport Roller, thereby correcting the skew.

2. Control of LCC Transport Motor HMOT A DC motor is used as HMOT which is energized and deenergized by the output signals f ed through pins 7 to 10 and 12 of CN6 by way of LCC Main Board PWB-A by the Master Board of the copier.
6-2. Paper Take-Up Mechanism
•
The paper take-up mechanism takes up a sheet of paper from the paper stack on each lift and feeds it to the Vertical Transport Roller.
•
A paper take-up sequence is performed when drive from LCC Transport Motor HMOT is transmitted via Take-Up Clutch 1/2 P1CL/P2CL to Paper Take-Up Roll 1/2. When Lift 1 runs out of paper, paper is then fed from Lift 2.
•
Mounted beneath Paper Take-Up Roll 1 of Lift 1 is a roll with a torque limiter that prevents a double feed of the last two sheets of paper.
•
Paper Take-Up Roll 1 is active when paper is fed from Lift 1.
•
When paper is fed from Lift 2, both Paper Take-Up Roll 1 and 2 are active to perform the paper take-up sequence. In that case, P aper Empty Sensor 1 PPS1 detects that a sheet of paper has been properly fed through Paper Take-Up Roll 1.
•
The sheet of paper taken up from Lift 1/2 is temporarily stopped at the Paper Standby Position Sensor to minimize variations in the position of the leading edge of the paper. When drive is transmitted by Separator Clutch BCL to the Separator Roll, the sheet of paper is then transported to the Vertical Transport Section.

6-3. Paper Take-Up Retry Control
To minimize the occurrence of paper misfeed due to a slippery P aper Take-Up Roll, Separa­tor Clutch BCL is energized a second time if a sheet of paper fails to reach Registration Sensor RSEN within a given period of time after BCL has first been energized. The control timing is as follows.
A paper misfeed results if the sheet of paper does not reach the Registration Sensor even after three paper take-up sequences.
4496T09MCB
6-4. Paper Separating Mechanism
The paper separating mechanism employs a system with a torque limiter that is fitted to the Separator Roll shaft and stops the Separator Roll when there is a change in friction between the Feed and Separator Rolls.
<Normal Feeding>
When only one sheet of paper is fed, the friction
Feed Roll
Paper
Separator Roll
4425M012AA
Driven or stationary
coefficient on the top side of the paper is equal to that on the underside. Driven by the Feed Roll, the paper drives the Separator Roll. This causes the paper to be sent to the Vertical Transport Sec­tion. The friction coefficient varies for dif ferent ambient conditions and types of paper being used, which often causes the Separator Roll to be stationary.
<Double Feeding>
Feed Roll 1st Sheet of Paper
2nd Sheet of Paper Separator Roll
4425M013AA
Stationary
Since the friction coefficient between the under­side of the second sheet of paper and Separator Roll is greater than that between the first and sec­ond sheets of paper, the Separator Roll is not driven and holds the second sheet of paper at the nip, allowing only the first sheet of paper to be f ed to the Vertical Transport Section.

6-5. Paper Pressure Releasing Mechanism
•
The LCC is provided with a mechanism that releases the pressure between the F eed and Separator Rolls and between the paper and Paper Take-Up Roll when the LCC is slid out of the copier.
•
The pressure between the Feed and Separator Rolls is released by the Separator Roll Assy and the Pressure Release Rail above the rail on the paper take-up end. When LCC is pulled out, the Pressure Release Rail pushes the Separator Roll Assy downward, thus releasing the pressure between the Feed and Separator Roll.
4496M007AB 4496M008AB
Pressure Release Rail
6-6. Paper Take-Up Roll Retracting Mechanism
The pressure between the paper and Paper Take-Up Roll is released by the projection on the back side of the Front Cover, Pressure Release Lever, and Paper Take-Up Roll Assy. When the LCC is slid out, it releases the Pressure Release Lever, which pushes the P aper Take-Up Roll upward to release pressure between the paper and Paper Take-Up Roll.

4496M012AA
6-10. Lifting Mechanism
When the LCC is slid into the copier, the couplings are engaged. When LCC Lift-Up Motor EMOT turns forward and backward, its drive is transmitted via a one-way gear and gear train to raise Lift 1 and Lift 2, in that order. A one-way gear is in each of the Lift 1 and 2 drive mechanisms. When EMOT turns for­ward, its drive is transmitted to Lift 1 and when the motor turns backward, its drive is trans­mitted to Lift 2.

When LCC is Slid in:
During a Copy Cycle:
4496M014AB
4496M015AB
LCC Set Sensor FRONT is blocked.
LCC Lift-Up Motor EMOT turns forward to raise Lift 1.
The paper stack causes the light blocking plate of the Paper Take-Up Roll 1 Assy to block Lift-Up Sensor 1 LS1.
EMOT is deenergized and then energized to start turning backward, thereby raising Lift 2.
The paper stack causes the light blocking plate of the Paper Take-Up Roll 2 Assy to block Lift-Up Sensor 2 LS2.
EMOT is deenergized.
Paper is consumed as copy cycles are run.
The Paper Take-Up Roll gradually lowers, unblocking the Lift-Up Sensor.
EMOT is energized and the Lift is raised. This lifts the paper stack to block the Lift-Up Sensor.
4496M014AB
Both Lift 1 and 2 perform these sequences of operations to keep a given pressure between the paper and Paper Take-Up Roll.
1. Lift 1 and 2 Ascent Conditions
•
The LCC is slid into position.
•
The Lift-Up Sensor is unblocked whil e a paper take-up sequence is being carried out with paper present on the Lift.
2. Lift 1 and 2 Stop Conditions

6-11. Paper Near Empty Detection
A paper-near-empty condition is detected by sensing the height of Lift 1 or Lift 2. When paper is consumed during a copy cycle, Lift 1 or 2 gradually mov es up. This eventually blocks the Paper Near Empty Sensor, at which timing the copier determines that the LCC
will soon run out of paper (the amount of paper (80 g/m sheets) and gives a corresponding message on the Touch Panel. Since the amount of paper still av ai lab le for use varies while a paper tak e-up sequence is i n progress, detection is made at a timing when the Paper Take-Up Roll is in the retracted position.
