IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the copier and peripherals,
make sure that the copi er po wer cord is un pl u gg ed.
2. The wall outle t sho ul d be near th e cop i er an d ea si ly accessib l e.
3. Note that the drum heater and the optional anti-condensation heaters are
supplied with electrical voltage even if the main switch is turned off.
4. If any adjustment or operation check has to be made with exterior covers
off or open while the main switch is turned on, keep hands away from
electrified or m ech an i cal ly dri ven components.
5. The inside and th e m et al pa r ts of the fusing unit become extre mel y ho t
while the copier is operating. Be careful to avoid touching those
components with your bare hands.
HEALTH SAFETY CONDITIONS
1 . 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 wit h wat er as fi r st aid. If unsuccessful, get medical
attention.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
1. The copier and its peripherals must be installed and maintained by a
customer service representative who has completed the training course
on those models.
CAUTION
2. The RAM board has a lithium battery which can explode if handled
incorrectly. Replace only with the same type of RAM board. Do not
recharge or burn this battery. Used RAM boards must be handled
in accordance with local regulations.
STM a A156/A160/A162
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1 . Do not incinerate toner cartridges or us ed toner. Toner dust may ignite
suddenly when exposed to open flame.
2. Dispose of used to ne r , de vel o pe r , an d or g an i c pho to con du ctors in
accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
4 . When keeping used lithium batteries (from the main control boards) in
order to dispose of th em lat er , do no t sto r e m or e tha n 10 0 ba tt er i e s (f rom
the main control boa r ds) pe r seale d bo x. Storing larger numbers or not
sealing them apart may lead to chemical reactions an d heat build-up.
