Appendix B — Firmware Upgrade
1. Note the proper orientation of the EC firmware IC in relationship to
the socket.
The notch in the IC must be oriented to coincide with the notch in the
IC socket.
2. Place the electrical fingers of the IC onto the socket, and make sure
they are aligned with the electrical receptacles of the socket.
3. Press down lightly and evenly on top of the IC so that the fingers begin
to engage the receptacles, and then press down firmly on the IC to
completely seat the IC.
4. Recheck that all fingers are engaged in their receptacles.
5. Re-slide the EC controller PCB into the card slides in the printer until
its rear edge butts against the edge connector inside the printer.
6. Push evenly near both corners of the PCB to seat the PCB.
The ejectors should automatically fold back to the edge of the PCB.
7. Re-install the RIP controller PCB.
See RIP Controller PCB Replacement in Appendix A.
Note:
When power is turned on after replacing firmware, the printer
halts with a
Self-Test Error
. This occurs because the printer
detects a mismatch between the previous checksum (the
arithmetic sum of all non-volatile RAM bytes) and the new
checksum. To remedy, simply turn power off and then on again
to restart the power-up procedure using the new expected
checksum.
