IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the printer and peripherals, make
sure that the power cord is unplugged.
2. The wall outlet should be near the printer 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 it 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 a finger down your
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.
CAUTION
The RAM has a lithium battery which can explode if handled incorrectly.
Replace only with the same type of RAM. Do not recharge or burn this
battery. Used RAM's must be handled in accordance with local regulations.
ATTENTION
La carte RAM comporte une pile au lithium qui présente un risque
d'explosion en cas de mauvaise manipulation. Remplacer la pile
uniquement par une carte RAM identique. Ne pas recharger ni brûler cette
pile. Les cartes RAM usagées doivent être éliminées conformément aux
réglementations locales.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Dispose of replaced parts in accordance with local regulations.
2. Used ink and masters should be disposed of in an environmentally safe
manner and in accordance with local regulations.
3. When keeping used lithium batte ries (from the main proce ssing units) in orde r
to dispose of them later, do not store more than 100 batteries (from the main
processing units) per sealed box. Storing larger numbers or not sealing them
apart may lead to chemical reactions and heat build-up.
