2F47 Hardware error.
3800500-2F47
Turn off printer,wait, then
turn on again. Only for iPF750 series The optical axis of the head management
sensor unit has been intercepted for some
reasons.
The amount of LED luminescence and the
level of detection signal of diode light
receiving sensitivity has gone beyond the
predefined range. (determines the level of
APCCHK)(It's not a problem of printhead
or ink supply system.)
1. Check whether any foreign matter
such as paper slip exists on the head
management sensor optical axis.
2. Light interception due to ink
accumulation.-> Remove the ink/
Replace the unit.
3. Check connection of the head
management sensor's connector.
4. Main controller PCB (Check the
fuse/ Replace the PCB.)
5. A large amount of ink mist has been
attached to optical element.
6. Replace the head management
sensor.
