Label Explanation
Risk of burns. Do not touch the internal enclosures of drying and
curing modules of the printer.
Risk of burns. Do not touch the drying enclosure of the printer.
Even after opening the window latch, which disconnects the
power to the drying and curing modules, the internal surfaces
could be hot.
Electric shock hazard. The printer has two input power cords. A
voltage is still present in the drying and curing modules after the
main switch is turned off. There are no operator-serviceable parts
inside the printer. Refer servicing to qualified service personnel.
Disconnect all power cords before servicing.
See installation instructions before connecting to the supply.
Ensure that the input voltage is within the printer's rated voltage
range. The printer requires two dedicated lines, each protected by
a branch circuit breaker according to the rating of the wall socket
outlet. Use only earthed mains outlets and the power cords
supplied by HP with the printer.
Risk of trapped hands. Do not push the roll while loading. Lift the
loading table to ease the spindle into the printer.
