Introduction ◦ Fuses have blown. ◦ The printer is not operating normally. ● Turn off the printer using both Branch Circuit Breakers in either of the following cases: ◦ During a thunderstorm ◦ During a power failure 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 both Branch Circuit Breakers located in the building's Power Distribution Unit (PDU) before servicing the printer. The printer must be connected to earthed mains outlets only. To avoid the risk of electric shock: ● Do not attempt to dismantle the drying and curing modules or the electrical control cabinet. ● 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, 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.

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 both Branch Circuit Breakers located in the building's Power Distribution Unit
(PDU) before servicing the printer. The printer must be connected to earthed mains outlets only.
To avoid the risk of electric shock:
●
Do not attempt to dismantle the drying and curing modules or the electrical control cabinet.
●
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
