Chapter 7 - DISASSEMBLY/REASSEMBLY OF PARTS
In this chapter are described the procedures for disassembling/reassembling the main components of the printer.
Each removal operation is described as follows:
• Reference to any previous removal operations so as to reverse the disassembly procedure;
• Phases of the operation described in sequence;
• Notes: indicate any references to adjustments to be made after reassembly, warnings or prescriptions to be
complied with.
PRELIMINARY WARNINGS
• For maximum safety, before carrying out any part disassembly operation, switch off the printer and disconnect it
from the mains.
• Perform all the operations in a clean, free area.
• Follow the procedure carefully; do not remove parts that must not be disassembled.
• After replacing parts, check that these have not become misshapen during assembly; if necessary, restore
initial conditions.
• Part reassembly operations must be carried out reversing the disassembly procedure.
• Make sure that all the connectors are correctly inserted. After the operation, relubricate where indicated.
• If the motherboard is replaced, update the firmware to the latest release (see the section “CONFIGURING THE
OPERATION PARAMETERS” on page 4 - 1) and calibrate electro-mechanical parts from the console (see the
section “CALIBRATING THE PHOTOSENSORS” on page 4 - 18).
• If the power supply unit is replaced, check that the mains voltage of the spare part matches the value indicated
on the electrical data plate of the printer.
• On completion of the operation, carry out a test to check the printer for any malfunctions.
