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 FOR TRANSPORTATION OF COPIER

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.
