● 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, and do not attempt to replace the fuse yourself. Checking the functionality of the Residual Circuit Breaker (RCCB Following standard Residual Current Circuit Breaker (RCCB) recommendations, it is recommended that the RCCB is test on a yearly basis. The procedure is as follows: 1. Switch off the printer from the Front Panel (do not switch off the printer from the mains switch or the circuit breakers). 2. When the printer is switched off, test that the RCCB functions correctly by pressing the test button. ● If the RCCB does not trip when the test button is pressed, this indicates that the component has failed. The device must be replaced for safety reasons, call HP Support to remove and replace the RCCB. ● If the RCCB trips, this indicates it is working correctly, return the printer to the original status and switch the printer on. Heat hazard The drying and curing subsystems of the printer operate at high temperatures and can cause burns if touched. To avoid personal injury, 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. 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 according to the information detailed in the Site Preparations Guide. ● Do not insert objects through slots in the printer. ● Take care not to spill liquid on the printer. ● Do not use aerosol products that contain flammable gases inside or around the printer. ● Do not block or cover the openings of the printer. ● Do not attempt to dismantle the drying or curing module, or the electrical control cabinet. ● Ensure that the operating temperature of the substrate loaded recommended by the manufacturer is not exceeded. If this information is not available by the manufacturer, do not load substrates that cannot be used at an operating temperature under 125°C (257°F). ● Do not load substrates with auto-ignition temperatures below 250°C (482°F).

●
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, and do not attempt to replace the fuse yourself.
Checking the functionality of the Residual Circuit Breaker (RCCB
Following standard Residual Current Circuit Breaker (RCCB) recommendations, it is recommended that
the RCCB is test on a yearly basis. The procedure is as follows:
1.
Switch off the printer from the Front Panel (do not switch off the printer from the mains switch or
the circuit breakers).
2.
When the printer is switched off, test that the RCCB functions correctly by pressing the test button.
●
If the RCCB does not trip when the test button is pressed, this indicates that the component
has failed. The device must be replaced for safety reasons, call HP Support to remove and
replace the RCCB.
●
If the RCCB trips, this indicates it is working correctly, return the printer to the original status
and switch the printer on.
Heat hazard
The drying and curing subsystems of the printer operate at high temperatures and can cause burns if
touched. To avoid personal injury, 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.
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 according
to the information detailed in the Site Preparations Guide.
●
Do not insert objects through slots in the printer.
●
Take care not to spill liquid on the printer.
●
Do not use aerosol products that contain flammable gases inside or around the printer.
●
Do not block or cover the openings of the printer.
●
Do not attempt to dismantle the drying or curing module, or the electrical control cabinet.
●
Ensure that the operating temperature of the substrate loaded recommended by the manufacturer
is not exceeded. If this information is not available by the manufacturer, do not load substrates that
cannot be used at an operating temperature under 125°C (257°F).
●
