9.1 GENERAL DISASSEMBLY/REASSEMBLY PRECAUTIONS
- To ensure maximum safety, before starting any disassembly operation power off the printer
and unplug its power cord from the electrical outlet.
- All operations should be performed in a clean and uncluttered area.
- Follow the procedures carefully; do not unscrew parts that are not to be disassembled.
- Store the disassembled parts in a clean place where there is no danger of them getting lost.
- After replacing the parts, make sure that they have not been deformed during assembly;
restore the correct conditions if necessary.
- Reassembly must be performed by following the disassembly procedures in reverse order.
- Before disconnecting the cables make sure to take note of their connections for reassembly.
- After servicing, lubricate where specified.
- When replacing the main board, update the firmware to the latest release (section 1.9.1), run
the installation set-up (Chapter 4) and then perform the electromechanical adjustments from
the console (Chapter 4).
- When replacing the power supply assembly, make sure that the line voltage rating of the
replacement module corresponds to the value indicated on the printer's electrical data plate.
- At the end of the service call, run an overall check on the printer to make sure that all failures
are corrected.
