Items to be Checked
OKI Data Infotech Corporation CONFIDENTIAL
The media edge may not be detected when the condition is
as follows.
- Black-surface media; or
- Matte media.
Try another media.
Check that the tape is not smeared. If it is, softly wipe it with
a soft cloth or lint-free paper dampened with wiper cleaning
liquid or cap cleaning liquid.
Check that the harness connector is securely connected to
the board's connector.
Remove the sensor, softly wipe it with a soft cloth or lint-free
paper dampened with ethanol, and re-connect it.
If the error persists, replace the sensor.
Softly wipe off any dirt on the linear scale with a soft cloth or
lint-free paper dampened with ethanol. Pay attention not to
damage the linear scale or remove any attached part.
If the linear scale is damaged, replace it.
Check that the harness connector are correctly connected
to the board connector.
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 of the FFC
is proper, and adjust if it is not. For the adjustment
procedure, see 6.8.4 PCB-ASSY-HCB1M.
Replace the PCB-ASSY-HCB1M.
Replace the PCB-ASSY-ACT3.
Replace the PCB-ASSY-IPB5-100.
Replace the robot cable.
Replace all four FFCs.
