General Precautions for Installation/Servicing/Maintenance
for the MR-2018/2019 and MY-1034
The installation and service should be done by a qualified service
technician.
1. When installing the MR-2018/2019 and MY-1034 to the Equipment, be sure to follow the instructions
described in the "Unpacking/Set-Up Procedure for the MR-2018/2019 and MY-1034" booklet which
comes with each unit of the MR-2018/2019 and MY-1034.
2. The MR-2016/3017 should be installed by an authorized/qualified person.
3. Before starting installation, servicing or maintenance work, be sure to turn OFF and unplug the
equipment first.
4. When servicing or maintaining the MR-2018/2019 and MY-1034, 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 disassembly 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 disassembled.
7. Delicate parts for preventing safety hazard problems (such as 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 electricity. Before using the wrist band, pull out
the power cord plug of the equipment and make sure that there is no uninsulated charged objects in
the vicinity.
11.For the recovery and disposal of used MR-2018/2019 and MY-1034, consumable parts and packing
materials, follow the relevant local regulations or rules.
12.After completing installation, servicing and maintenance of the MR-2018/2019 and MY-1034, return
the MR-2018/2019 and MY-1034 to its original state, and check operation.

cabinet cover and secure the cover with the screw.
At this time, check that the three pawls of the rear cabinet cover
are fitted into the rear cabinet.
10) Attach the ADF to the copier.
Attach the ADF by inserting the hinge guide sections of the
ADF into the hinge guides L and R.
11) Insert the power plug into the outlet and turn the main switch of
the copier to the “ON” position.
12) Perform SIM setting.
[MR-2018]
Execute simulation [2] of [26] and enter [1].
[MR-2019]
Execute simulation [2] of [26] and enter [2].
13) Carry out automatic adjustment of ADF scanning position.
Use a black sheet and execute simulation [53]-[08] to carry out
automatic adjustment of ADF scanning position.
For details, see the service manual.
14) Adjust the floating detection level of ADF.
Close the ADF and use simulation code [41]-[06] to adjust the
floating detection level of ADF.
For details, see the service manual.
15) Check the copy ratio, and then check the center displacement
and leading edge image void.
Place an original on the document glass and make a copy.
Then, place an original in the document feeder tray and make a
copy.
If the center of the copy from the document glass is displaced
from the copy from the document feeder, adjust the center
referring to the service manual of e-STUDIO202S.

MR-2019 JAM generation condition
1) The SPPD is ON when turning ON the power.
2) The SPPD does not turn ON for 4.0sec from starting document
feed. (in 100% copy)
3) The SPPD does not turn OFF for 4.7sec after detecting turning
ON of the SPPD. (100% copy)
4) The RADF cover or the OC cover is opened during document
transportation.
5) The SRJD is ON when the power is turned ON.
6) The SRJD is not turned ON for 2.4sec from release of PS in
paper feed from the document set position. (100% copy)
7) The SRJD is not turned OFF for 1.6sec from completion of doc-
ument scan in the case of complete document exit. (100%
copy)
MR-2018 JAM generation condition
1) When SPPD is ON (document remaining) in initializing.
2) When SPPD is not turned ON within about 4.0 sec (at 100%
copy) after starting the document feed operation.
3) When SPPD is not turned OFF within about 4.7 sec (at 100%
copy) after turning on SPPD.
4) When the OC cover is opened during document transport (dur-
ing ADF motor rotation) (The ADF motor is stopped during doc-
ument transport, but the OC cover open error occurs instead of
the ADF JAM.)
2. RADF/ADF open/close detection
(book document detection)
RADF/ADF open/close detection (book document) detection is per-
formed by detecting the interval between the reference lines on the
white Mylar attached to the paper exit guide (document scanning
section) by the scanner (CCD) and detecting the varied quantity.
Note: When replacing the carriage unit, be sure to execute SIM41-
06.
If SIM41-06 is not executed, the carriage unit may not read
the reference line on the white Mylar, preventing the docu-
ment from being fed.
