Safety precautions 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 Current Circuit Breaker (RCCB) every 6 months. 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. Even after opening the window latch that disconnects drying and curing power, the internal surfaces could be hot. ● 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 rating of the wall socket. Do not use a power strip (relocatable power tap) to connect both power cords. ● Use only the power cords supplied by HP with the printer. Do not use a damaged power cord. Do not use the power cords with other products. ● 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 from 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 300°C (572°F). See note below. 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. 2 Chapter 1 Safety precautions ENWW
