Preliminary Precautions - Olivetti PR2 Service Manual

9.1 PRELIMINARY PRECAUTIONS

- To ensure the maximum safety, before starting any disassembly operation, shut down and
disconnect the printer from the mains.
- All the operations should be carried out in a clean, uncluttered area.
- Follow the procedure carefully; do not unscrew parts that are not to be disassembled.
- Keep the disassembled parts in a clean place where there is no danger of losing them.
- After replacing parts, check that these have not been deformed during the assembly; if
necessary restore the correct conditions.
- Re-assembly must be carried out using the same disassembly procedure in reverse.
- 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 with the latest release (section 1.9.1),
run installation setup (section 4) and perform the electromechanical adjustments via
console (section 4).
- When replacing the power supply board or transformer, 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 intervention run an overall check on the printer to make sure that
all failures are corrected.
