651 Replace NCU • The light source LED has
dimmed to unusable
levels due to deterioration,
dirt, or damage.
• Occurs if the result of
executing [#Test] > [NCU]
> [Sensor Chk] is less
than [100].
No nozzle clogging in test print:
1. Clean the left- and right-hand side inner walls
of the NCU detection slit with a cleaning stick.
2. Check the cable connection for damage
between the PD_AMP PCB (CN1) and the
Base IO PCB (CN11).
3. Replace the NCU.
4. Replace the Base IO PCB.
652 NCU Nzk Chk (Hw) • The HW was unable to
sample the NCU
discharge pattern.
• The nozzles are badly
clogged or deflection is
occurring.
• The NCU Y discharge
position is offset,
preventing discharge at
the NCU slit.
No nozzle clogging in test print:
1. Check the cable connection for damage
between the PD_AMP PCB (CN1) and the
Base IO PCB (CN11).
2. Replace the NCU.
3. Replace the Base IO PCB.
4. Perform [#Adjust] > [NCU] > [Pos Adj].
653 NCU NZK CHK
(Mark)
• The NCU discharge
pattern analysis revealed
discharge not in
compliance with the
evaluation criteria.
• An effective evaluation is
not possible due to
excessive nozzle clogging
or deflection.
No nozzle clogging in test print:
1. Check the cable connection for damage
between the PD_AMP PCB (CN1) and the
Base IO PCB (CN11).
2. Replace the NCU.
3. Replace the Base IO PCB.
654 NCU Center Pos • NCU central position
detection failed.
• An effective evaluation is
not possible due to
excessive nozzle clogging
or deflection.
655 NCU Flush Pos • Sensor sensitivity
optimum position
detection failed.
• An effective evaluation is
not possible due to
excessive nozzle clogging
or deflection.
656 NCU SN Adjst • Brightness adjustment to
achieve optimum
sensitivity failed.
• An effective evaluation is
not possible due to
excessive nozzle clogging
or deflection.
• Deterioration, dirt, or
damage to the light source
LED has reduced
brightness.
