5.5.48 System Error 2b00: FIRE END Detection Error
<Description>
This error occurs when the FIRE END flag could not be detected.
Normally, at each scan, the FIRE END flag is issued when the droplets ejection is completed.
<Faulty part>
(1) CABLE ENCODER, MW (linear encoder)
(2) PCB-ASSY-HCB1M
(3) PCB-ASSY-IPB5-100
(4) Linear scale: ENCODER STRIP, MW
(5) Carriage cable (FFC): CARRIAGE FFC, MW
(6) Robot cable: ROBOT CABLE, MW

Items to be Checked
OKI Data Infotech Corporation CONFIDENTIAL
Check that the harness condition is proper as follows.
- The connectors are connected securely.
- The cable is not disconnected.
- The harness is not pinched by other parts.
- The cable jacket is not damaged.
Check that the linear encoder is clean and not damaged.
(1) Clean the linear encoder by wiping it softly with a soft cloth
moisten with ethanol. Take care not to damage the encoder
or remove any attach part.
(2) If the encoder is damaged, replace it.
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.
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.
Reconnect the robot cable on both the PCB-ASSY-HCB1M side
and PCB-ASSY-ACT3 side.
Before connecting, check that the connector terminals and cable
connection part are not disconnected. If a connection failure is
found, replace the robot cable.
Replace the PCB-ASSY-HCB1M.
Replace the PCB-ASSY-IPB5-100.
