SAFETY INFORMATION
S-9
[3] CONCLUSION
1. Safety of users and customer engineers depends highly on accurate maintenance and administration.
Therefore, safety can be maintained by the appropriate daily service work conducted by the customer
engineer.
2. When performing service, each copier on the site must be tested for safety. The customer engineer must
verify the safety of parts and ensure appropriate management of the equipment.
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration implemented
regulations for laser products manufactured since August 1, 1976. Compliance is mandatory for products mar-
keted in the United States.
This copier is certified as a “Class 1” laser product under the U.S.
Department of Health and Human Services (DHHS) Radiation Performance Standard according to the Radiation
Control for Health and Safety Act of 1968. Since radiation emitted inside this copier is completely confined within
protective housings and external covers, the laser beam cannot escape during any phase of normal user opera-
tion.
DANGER: HANDLING OF MATERIALS FOR SERVICING
• Toner and developer are not harmful substances, but care must be taken not
to breathe excessive amounts or let the substances come into contact with
eyes, etc. It may be stimulative.
If the substances get in the eye, rinse with plenty of water immediately.
When symptoms are noticeable, consult a physician.
• Never throw the used cartridge and toner into fire.
You may be burned due to dust explosion.

This machine is provided with the following safety cir-
cuits to prevent machine faults from resulting in seri-
ous accidents.
[1] Overall protection circuit
[2] L2 and L3 (fixing heater lamps) overheating
prevention circuit
These safety circuits are described below to provide
the service engineer with a renewed awareness of
them in order to prevent servicing errors that may
impair their functions.
[1] Overall Protection Circuit
1. Protection by CBR1 and CBR2 (circuit
breakers)
CBR1 and CBR2 interrupt the AC line instanta-
neously when an excessive current flows due
to a short in the AC line.
CAUTION:
The CBR1 and CBR2 functions must not
be deactivated under any circumstances.
[2] Protection by L2, L3 and L4 (fixing
heater lamps) overheating prevention
circuit
1. Protection by software
The output voltage from TH1 (fixing tempera-
ture sensor 1) is read by the CPU. If this volt-
age is abnormal, L2 (fixing heater lamp 1), L3
(fixing heater lamp 2), L4 (fixing heater lamp 3)
and RL1 (main relay) are turned OFF.
CAUTION:
Do not change the gap between the roller
and TH1. When replacing TH1, check the
specified mounting dimensions. The RL1
function must not be deactivated under
any circumstances.

2. Protection by the hardware circuit
The output voltages from TH1 and TH2 (fixing
temperature sensors) are compared with the
abnormality judgment reference value in the
comparator circuit. If the output voltage from
TH1 or TH2 exceeds the reference value, L2
(fixing heater lamp 1), L3 (fixing heater lamp
2), L4 (fixing heater lamp 3) and RL1 (main
relay) are turned OFF in hardware means.
CAUTION:
Periodically check the TH2 face contact-
ing the roller, and replace TH2 if any
abnormality is detected.
Since TH1 (fixing temperature sensor)
face does not contact the roller, check the
distance from the roller and the sensor
orientation if any abnormality is detected.
The RL1 function must not be deactivated
under any circumstances.
3. Protection by TS1 (thermostat/U) and TS2
(thermostat/L)
When the temperature of the fixing roller
(upper/lower) exceeds the specified value, TSs
are turned OFF, thus interrupting the power to
L2 (fixing heater lamp/1), L3 (fixing heater
lamp/2), and L4 (fixing heater lamp/3) directly.
CAUTION:
Do not use any other electrical conductor
in place of TS1 and TS2. Do not change
the distance between the roller and TS
(thermostat).
