PREVENTION OF PHYSICAL INJURY

1. Before disassembling or assembling parts of the machine, make sure

that the power cord is unplugged.

2. The wall outlet should be near the machine and easily accessible.

3. 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 mechanically driven components.

HEALTH SAFETY CONDITIONS

1. If you get ink in your eyes by accident, try to remove with eye drops or

flush with water as first aid. If unsuccessful, get medical attention.

2. If you ingest ink by accident, induce vomiting by sticking finger down

throat or by giving soapy or strong salty water to drink.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

1. The printer 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
