Electrical shock hazard WARNING! The internal circuits and drying and curing modules operate at hazardous voltages capable of causing death or serious personal injury. Turn off the printer using the Branch Circuit Breakers located in the building's Power Distribution Unit (PDU) before servicing the printer. The printer must be connected to earth at mains outlets only. To avoid the risk of electric shock: ● Do not attempt to dismantle the drying and curing modules or e-cabinet during hardware maintenance tasks. In that case, follow the instructions strictly. ● Do not remove or open any other closed system covers or plugs. ● Do not insert objects through slots in the printer. ● Test the functionality of the Residual Circuit Breaker (RCCB) every year (refer to the procedure below). NOTE: A blown fuse may indicate malfunctioning electrical circuits within the system. Call your service representative (see HP Customer Care Centers on page 10), and do not attempt to replace the fuse yourself. Checking the functionality of the Residual Circuit Breakers (RCCBs) Following standard Residual Current Circuit Breaker (RCCB) recommendations, it is recommended that the RCCBs are tested on a yearly basis. The procedure is as follows: 1. Turn off the built-in computer using the Internal Print Server's Shutdown button (or, in Print Care, select Printer tools > Power options > Shutdown). Do not turn off the printer from the mains switch or the circuit breakers. CAUTION: The shutdown process takes some time to complete. Wait until the green Power Enabled light is off before proceeding. 2. Once the computer is off, test that the RCCB works correctly by pressing the test button. ● If the RCCB does not trip when the test button is pressed, this indicates that it has failed. The RCCB must be replaced for safety reasons; call your service representative to remove and replace the RCCB. ● If the RCCB trips, this indicates it is working correctly; reset the RCCB to its normal on state. Heat hazard The drying and curing subsystems of the printer operate at high temperatures and can cause burns if touched. LED's array supports, beam and enclosures can reach high temperatures. To avoid the risk of burns, take the following precautions: ● Do not touch the internal enclosures of the printer's drying and curing modules. ● Take special care when accessing the substrate path. ● Take special care with zones marked with warning labels. ● Do not place objects covering LED's arrays supports, beam and enclosures. ● Do not attempt to modify LED's array supports, beam and enclosures; ● Remember to let the printer cool down before performing some maintenance operations. 2 Chapter 1 Safety precautions ENWW

Electrical shock hazard
WARNING!
The internal circuits and drying and curing modules operate at hazardous voltages capable of
causing death or serious personal injury.
Turn
off
the printer using the Branch Circuit Breakers located in the building's Power Distribution Unit (PDU)
before servicing the printer. The printer must be connected to earth at mains outlets only.
To avoid the risk of electric shock:
●
Do not attempt to dismantle the drying and curing modules or e-cabinet during hardware maintenance
tasks. In that case, follow the instructions strictly.
●
Do not remove or open any other closed system covers or plugs.
●
Do not insert objects through slots in the printer.
●
Test the functionality of the Residual Circuit Breaker (RCCB) every year (refer to the procedure below).
NOTE:
A blown fuse may indicate malfunctioning electrical circuits within the system. Call your service
representative (see
HP Customer Care Centers
on page
10
), and do not attempt to replace the fuse yourself.
Checking the functionality of the Residual Circuit Breakers (RCCBs)
Following standard Residual Current Circuit Breaker (RCCB) recommendations, it is recommended that the
RCCBs are tested on a yearly basis. The procedure is as follows:
1.
Turn
off
the built-in computer using the Internal Print Server’s
Shutdown
button (or, in Print Care, select
Printer tools
>
Power options
>
Shutdown
). Do not turn
off
the printer from the mains switch or the
circuit breakers.
CAUTION:
The shutdown process takes some time to complete. Wait until the green Power Enabled
light is
off
before proceeding.
2.
Once the computer is
off,
test that the RCCB works correctly by pressing the test button.
●
If the RCCB does not trip when the test button is pressed, this indicates that it has failed. The RCCB
must be replaced for safety reasons; call your service representative to remove and replace the
RCCB.
●
If the RCCB trips, this indicates it is working correctly; reset the RCCB to its normal on state.
Heat hazard
The drying and curing subsystems of the printer operate at high temperatures and can cause burns if
touched. LED's array supports, beam and enclosures can reach high temperatures. To avoid the risk of burns,
take the following precautions:
●
Do not touch the internal enclosures of the printer's drying and curing modules.
●
Take special care when accessing the substrate path.
●
Take special care with zones marked with warning labels.
●
Do not place objects covering LED's arrays supports, beam and enclosures.
●
Do not attempt to modify LED's array supports, beam and enclosures;
●
Remember to let the printer cool down before performing some maintenance operations.
