General safety guidelines
Before servicing the printer, read the following safety precautions to make sure that you can work on the
printer safely.
●
Before servicing the printer, turn it off, and disconnect electrical power. See
Safety precautions
on page 460.
●
Before removing and replacing parts, see
Removal and installation on page 232.
Service personnel are expected to have appropriate technical training and experience necessary to be aware
of hazards to which they may be exposed in performing a task, and to take appropriate measures to minimize
the risks to themselves and other people.
Electrical shock hazard
WARNING! The curing modules operate at hazardous voltages capable of causing death or serious personal
injury.
The printer uses two power cords. Disconnect both power cords before servicing the printer to avoid the risk
of electric shock. The printer must be connected to earthed mains outlets only.
The internal circuits of curing zones, print-zone heaters, impinging module, vapor removal, e-box, and e-box
extension operate at hazardous voltages capable of causing death or serious personal injury. Disconnect
both power cords before servicing the printer.
Heat hazard
The curing subsystems of the printer operate at high temperatures and can cause burns if touched. To avoid
personal injury, take the following precautions.
●
Let the printer cool down before performing servicing or maintenance operations.
●
Take special care when accessing the substrate path.
Fire hazard
The curing modules operate at high temperatures. To avoid the risk of fire, take the following precautions.
●
Check that the power supply meets the requirements specified in the site preparation guide. For
additional information, see
Printer systems on page 1.
●
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 the power cords.
●
Do not use aerosol products that contain flammable gases inside or around the printer.
●
Do not use a damaged power cord. Do not use the power cords with other products.
●
Do not block or cover the openings of the printer.
●
Ensure that the operating temperature of the substrate, as recommended by its manufacturer, is not
exceeded. If this information is not available from the manufacturer, be sure to use only substrates
suitable for operating temperatures of 125°C (257°F) or higher.
●
Do not load substrates with auto-ignition temperatures below 250°C (482°F). If this information is not
available, printing must be supervised at all times.
