5.7 Replacing the CPU PCB

Figure 12

1.  If possible, save the printer configuration to a CompactFlash card.
2.  Unplug the printer from the electrical outlet.
3.  Detach all interface cables from the back of the printer.
4.  Remove the memory card from the slot.
5.  Screw off the rear cover.
6.  Unplug all side plug connections from the CPU PCB (2).
7.  Remove the three fixing screws (3) from the CPU PCB.
8.  Carefully remove the CPU PCB.

1.  Place CPU PCB (2) onto the retainers (1).
2.  Secure the PCB with three screws (3).
3.  Insert all plug connections on the PCB.
4.  Pull the label photocell toward the cover side as far as possible

(see chapter 5.6, on page 21) and install the rear cover of the
printer.

5.  Restore all interface connections on the back of the printer.
6.  Connect the power cable at the rear of the printer.
7.  Update the firmware if necessary.
8.  Adjust the label photocell.
9.  Load the printer configuration from the memory card if possible.
