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:
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 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 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.
Test method based on EN ISO 6942:2002: Evaluation of materials and material assemblies when
NOTE:
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:
