NOTE: A blown fuse may indicate malfunctioning electrical circuits within the system. Call your service representative, and do not attempt to replace the fuse yourself. Checking the functionality of the Residual Current Circuit Breakers 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. 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. Fire hazard 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 that it is working correctly; reset the RCCB to its normal on state. The drying and curing subsystems of the printer operate at high temperatures. Call your service representative if the printer's built-in Residual Current Circuit Breaker (Ground Fault Circuit Interrupter) is repeatedly tripped. To avoid the risk of fire, take the following precautions: ● Use the power supply voltage specified on the nameplate. ● Connect the power cords to dedicated lines, each protected by a branch circuit breaker as explained in the site preparation guide. ● Do not insert objects through slots in the printer. ● Take care not to spill liquid on the printer. After cleaning, make sure all components are dry before using the printer again. ● Do not use aerosol products that contain flammable gases inside or around the printer. Do not operate the printer in an explosive atmosphere. ● Do not block or cover the openings of the printer. ● Do not attempt to modify the drying or curing module, or the e-cabinet. ● Ensure that the operating temperature of the substrate recommended by the manufacturer is not exceeded. If this information is not available, ask the manufacturer. Do not load substrates that cannot be used at an operating temperature above 125°C (257°F). ● Do not load substrates with auto-ignition temperatures below 250°C (482°F). See note below. No ignition sources are close to the substrate. NOTE: Test method based on EN ISO 6942:2002: Evaluation of materials and material assemblies when exposed to a source of radiant heat, method B. The test conditions, to determine the temperature when the substrate starts ignition (either flame or glow) were: Heat flux density: 30 kW/m², Copper calorimeter, K type thermocouple. ● Proper maintenance and genuine HP consumables are required to ensure that the printer operates safely as designed. The use of non-HP consumables (foams, filters, printhead cleaner roll, and inks) may present a risk of fire. ● The LED array supports, beam, and enclosures can reach high temperatures. To avoid the risk of fire, take the following precautions: ENWW 3

Checking the functionality of the Residual Current Circuit Breakers
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 o
ff
the built-in computer using the Internal Print Server’s
Shutdown
button. Do not turn o
ff
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
o
ff
before proceeding.
2.
Once the computer is o
ff
, 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 that it is working correctly; reset the RCCB to its normal on state.
Fire hazard
The drying and curing subsystems of the printer operate at high temperatures. Call your service representative if the
printer’s built-in Residual Current Circuit Breaker (Ground Fault Circuit Interrupter) is repeatedly tripped. To avoid the
risk of
fi
re, take the following precautions:
●
Use the power supply voltage speci
fi
ed on the nameplate.
●
Connect the power cords to dedicated lines, each protected by a branch circuit breaker as explained in the site
preparation guide.
●
Do not insert objects through slots in the printer.
●
Take care not to spill liquid on the printer. After cleaning, make sure all components are dry before using the
printer again.
●
Do not use aerosol products that contain
fl
ammable gases inside or around the printer. Do not operate the
printer in an explosive atmosphere.
●
Do not block or cover the openings of the printer.
●
Do not attempt to modify the drying or curing module, or the e-cabinet.
●
Ensure that the operating temperature of the substrate recommended by the manufacturer is not exceeded.
If this information is not available, ask the manufacturer. Do not load substrates that cannot be used at an
operating temperature above 125°C (257°F).
●
Do not load substrates with auto-ignition temperatures below 250°C (482°F). See note below. No ignition
