Turn o the printer using the Branch Circuit Breakers in either of the following cases:
• During a thunderstorm
• During a power failure
Take special care with zones marked with warning labels.
Electrical shock hazard
Warning: The internal circuits, the drying and curing modules operate at hazardous voltages capable of causing death or
serious personal injury.
Turn o the printer using the Branch Circuit Breakers located in the building’s Power Distribution Unit (PDU) before
servicing the printer. The printer must be connected to earth at mains outlets only.
To avoid the risk of electric shock:
• Do not attempt to dismantle the drying and curing modules, or the e-cabinet except during hardware maintenance
tasks. In that case, follow the instructions strictly.
• 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 Breakers (RCCBs)
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 the built-in computer using the Internal Print Server’s Shutdown button (or, in Print Care, select Printer tools
> Power options > Shutdown). Do not turn o 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 before
proceeding.
2. Once the computer is o, 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 re, take the following precautions:
• Use the power supply voltage specied 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 documentation.
• 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 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 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 ame or glow) were: Heat ux 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, lters, printhead cleaner roll, and inks) may present a risk of re.
