General Precautions for Installation/Servicing/Maintenance for the MR-3011/3012
The installation and service should be done by a qualified service technician.
1. When installing the MR-3011/3012 to the Plain Paper Copier, be sure to follow
the instructions described in the "Unpacking/Set-Up Procedure for the MR-3011/
3012" booklet which comes with each unit of the MR-3011/3012.
2. The MR-3011/3012 should be installed by an authorized/qualified person.
3. Before starting installation, servicing or maintenance work, be sure to turn off
and unplug the copier first.
4. When servicing or maintaining the MR-3011/3012, be careful about the rotating
or operation sections such as gears, pulleys, sprockets, cams, belts, etc.
5. When parts are disassembled, reassembly is basically the reverse of disassem-
bly unless otherwise noted in this manual or other related materials. Be careful
not to reassemble small parts such as screws, washers, pins, E-rings, toothed
washers to the wrong places.
6. Basically, the machine should not be operated with any parts removed or disas-
sembled.
7. Delicate parts for preventing safety hazard problems (such as breakers,
thermofuses, fuses, door switches, sensors, etc.if any) should be handled/
installed/adjusted correctly.
8. Use suitable measuring instruments and tools.
9. During servicing or maintenance work, be sure to check the serial No.plate and
other cautionary labels (if any) to see if they are clean and firmly fixed. If not,
take appropriate actions.
10. The PC board must be stored in an anti-electrostatic bag and handled carefully
using a wristband, because the ICs on it may be damaged due to static electric-
ity. Before using the wrist band, pull out the power cord plug of the copier and
make sure that there is no uninsulated charged objects in the vicinity.
11. For the recovery and disposal of used MR-3011/3012s, consumable parts and
packing materials, it is recommended that the relevant local regulations/rules
should be followed.
12. After completing installation, servicing and maintenance of the MR-3011/3012,
return the MR-3011/3012 to its original state, and check operation.

PREPARATION FORTRANSPORTATION OF COPIER
Before transporting a copier on which mounts the MR-3011/3012, take off the MR-
3011/3012 or insert a gaggers underneath the MR-3011/3012 as shown in the
following figures.
1. Use pieces of the corrugated board came in the package of MR-3011/3012 or
equivalent as the gaggers. Insert the gaggers as shown in the figure, then close
the MR-3011/3012.
2. Make sure that the height positioning stud is not in contact with the original
glass.

The following 6 lines are used to send/receive signals between the copier and the RADF.
REQ .............Communication request signal (from copier to RADF)
DF-REQ .......Communication request signal (from RADF to copier)
DF-ACK........Response signal for communication request signal (from RADF to copier)
ACK ..............Response signal for communication request signal (from copier to RADF)
TxD ..............Data sent from copier to RADF
RxD ..............Data sent from RADF to copier
Data communication (RxD and TxD) between the scanner and RADF has adopted the serial communication
system which does not allow checking using testing devices to see whether the signals are sent/received
properly in the field.

5. DESCRIPTION OF OPERATIONS
5.1 Single Side Feeding
(A4, registration ratio 100%)
(1) Setting original
The original is set on the tray and the empty sensor is turned ON.
The original set signal becomes ON.
(2) Start of pre-feeding operation nCompletion of pre-feeding operation
A feed signal is sent from the main unit, and the feed motor rotates the pickup roller and feed motor to start
feeding the original (pre-feeding operation).
(3) Start of feeding operation nOriginal length sensor OFF
The feed motor starts to rotate in reverse and the read motor rotates forward to rotate the registration roller and
the read roller while the original is waiting in front of the registration roller and read roller starts to be transported.
The feed motor is stopped after the original length sensor is turned OFF.
#Chapter_05.p65 10/5/00, 9:55 AM1

5-2
October 2000 © TOSHIBATEC MR-3011/3012 DESCRIPTION OF OPERATION
(4) Original length sensor OFF nCompletion of sending operation
If the next original is waiting in the tray, the pickup roller is lowered after the feed motor which has started to
rotate forward rotates for a certain number of pulses. (The pickup roller waits for the next pre-feeding operation in
that lowered position.)
The read motor rotates for a certain number of pulses and stops after the read sensor is turned ON. (The leading
edge of the original reaches the pre-scanning position.)
(5) Start of scanning operation nStart of pre-feeding operation for next original
The original transport signal is sent from the main unit, and the read motor starts to rotate forward.The read
roller and exit roller are rotated to start scanning the original.The feed motor rotates the pickup roller and feed
roller after the trailing edge of the original has passed the registration roller to start the pre-feeding operation for
the next original.
(6) Start of pre-feeding operation for next original nCompletion of pre-feeding operation
After the registration sensor has detected the leading edge of the original.The feed motor transports the original
for a certain number of pulses, performs registration and stops.

5-3
October 2000 © TOSHIBATEC MR-3011/3012 DESCRIPTION OF OPERATION
(7) Start of feeding operation for next original nCompletion of scanning operation
The feed motor starts to rotate in reverse, it rotates the registration roller to feed the next original waiting in front
of the registration roller and read roller.
The original set signal is reset when the empty sensor is turned OFF.The feed motor is stopped after the original
length sensor is turned OFF.
The scanning operation is completed when the trailing edge of the original being scanned has passed the
scanning position.
(8) Completion of scanning operation nCompletion of feeding operation for next original
The read motor rotates for a certain number of pulses and stops after the read sensor is turned ON.
(The leading edge of the next original reaches the pre-scanning position.)
(9) Start of scanning operation for next original nCompletion of original discharge
The read motor starts to rotate forward, it rotates the read roller and exit roller to start scanning the next original.
Original discharge is completed when the trailing edge of the original has passed the exit roller.
