5.5.6 System Error 1320: Data Transfer Error from FPGA-RSM to FPGA-PTG
<Description>
Connection failed with the carriage cable (FFC) connected to the PCB-ASSY-IPB5-100.
This error is detected through the process below:
(1) The printer is started; and
(2) The write test from the PCB-ASSY-IPB5-100(RSM) to the PCB-ASSY-HCB1M(PTG)
fails.
<Faulty part>
(1) PCB-ASSY-HCB1M
(2) PCB-ASSY-IPB5-100
(3) Carriage cable (FFC): CARRIAGE FFC, MW
<Action>
Check the Items to be Checked on the table below, and perform the actions starting from the top
until the problem is solved.

Action
Check that the screws are tightened.
Reconnect the FFC on both the PCB-ASSY-HCB1M side
and the PCB-ASSY-IPB5-100 side.
If the cable terminals are smeared, softly wipe them with a
soft cloth or lint-free paper dampened with ethanol before
connecting them.
Check that the width of the V-shaped folded part on the
FFC is proper. If not, adjust it. For the adjustment
procedure, see 6.8.4 PCB-ASSY-HCB1M.
Check the following to ensure that the FFC is not
damaged.
- FFC's terminal is detached from its base.
- FFC's edges have not been abraded by friction.
If the FFC is damaged, replace it.
Replace the PCB-ASSY-HCB1M.
Replace the PCB-ASSY-IPB5-100.
Replace all four FFCs.
