Safety Notices and Symbols & Abbreviations
Important Safety Notices
Prevention of Physical Injury
1. Before disassembling or assembling parts of the copier and peripherals,
make sure that the power cord is unplugged.
2. The wall outlet should be near the copier and easily accessible.
3. Note that some components of the copier and the paper tray unit are
supplied with electrical voltage even if the main power switch is turned off.
4. If a job has started before the copier completes the warm-up or initializing
period, keep hands away from the mechanical and electrical components
because the starts making copies as soon as the warm-up period is
completed.
5. The inside and the metal parts of the fusing unit become extremely hot
while the copier is operating. Be careful to avoid touching those
components with your bare hands.
Health Safety Conditions
Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it
may cause temporary eye discomfort. Try to remove with eye drops or flush with water as
first aid. If unsuccessful, get medical attention.
Observance of Electrical Safety Standards
The copier and its peripherals must be installed and maintained by a customer service
representative who has completed the training course on those models.
Safety and Ecological Notes for Disposal
1. Do not incinerate toner bottles or used toner. Toner dust may ignite
suddenly when exposed to an open flame.
2. Dispose of used toner, developer, and organic photoconductors in
accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
Laser Safety
The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based
optical units in the field. The optical housing unit can only be repaired in a factory or at a
location with the requisite equipment. The laser subsystem is replaceable in the field by a
qualified Customer Engineer. The laser chassis is not repairable in the field. Customer
Engineers are therefore directed to return all chassis and laser subsystems to the factory
or service depot when replacement of the optical subsystem is required.
-1. Use of controls, or adjustment, or performance of procedures other than
those specified in this manual may result in hazardous radiation exposure.
WARNING FOR LASER UNIT
WARNING: Turn off the main switch before attempting any of the procedures in the
Laser Unit section. Laser beams can seriously damage your eyes.

buffer.
-6850555. Turn off the main switch and disconnect the power cord, the telephone
line, and the network cable.
1.1.1 ENVIRONMENT
–Temperature and Humidity Chart–
Installation
1. Temperature Range: 10C to 32C (50F to 89.6F)
1. Humidity Range: 15% to 80% RH
1. Ambient Illumination: Less than 1,500 lux (do not expose to direct sunlight)
1. Ventilation: 3 times/hr/person or more
1. Ambient Dust: Less than 0.075 mg/m3 (2.0 x 10-6 oz/yd3)
1. Avoid areas exposed to sudden temperature changes:

SM 1-1 B245/B268/B269/B276/B277
Installation Requirements
1. Do not install the machine at any location over 2,000 m (6,500 ft.) above sea level.
1. Place the machine on a strong and level base. (Inclination on any side should be no
more than 5 mm.)
1. Do not place the machine where it is subjected to strong vibrations.
1.1.2 MACHINE LEVEL
Front to back: Within 5 mm (0.2") of level
Right to left: Within 5 mm (0.2") of level
1.1.3 MINIMUM SPACE REQUIREMENTS
Place the copier near the power source, providing clearance as shown:
A (front): 750 mm (30")
B (left): 150 mm (6")
C (rear): 50 mm (2")
D (right): 250 mm (10")
The recommended 750 mm front space is sufficient to allow the paper tray to be pulled out.
Additional front space is required to allow operators to stand at the front of the machine.
