Removal precautions
CAUTION—SHOCK HAZARD
The low-voltage power supply (LVPS) and the high-voltage power supply
(HVPS) may have residual voltage present. To avoid the risk of electrical
shock, do not touch their circuit components or the solder side of the board.
Only handle them by their outer edges or metal housing.
CAUTION—SHOCK HAZARD
This product uses an electronic power switch. It does not physically
disconnect the input AC voltage. To avoid the risk of electrical shock,
always remove the power cord from the printer when removal of the input
AC voltage is required.
CAUTION—SHOCK HAZARD
To avoid the risk of electrical shock and to prevent damage to the printer,
remove the power cord from the electrical outlet and disconnect all
connections to any external devices before you connect or disconnect any
cable, electronic board, or assembly.
CAUTION—HOT SURFACE
The inside of the printer might be hot. To reduce the risk of injury from a hot
component, allow the surface to cool before touching it.
CAUTION—PINCH HAZARD
To avoid the risk of a pinch injury, use caution in areas marked with this
label. Pinch injuries may occur around moving parts, such as gears, doors,
trays, and covers.
