Section 16 CONTROL SYSTEM (FRN)
Check the coil resistance of the feed clutch, which should
be between 206 ohms and 248 Ohms, and replace the
clutch if this is incorrect
Check the voltage to the feed clutch which should be
24VDC and replace PCB if this is incorrect.
Feed wheels operate for one sheet and fail to operate thereafter.
Check that the rotation sensor micro-switch (which is
located on the main clutch back plate), is operated by the
clutch stop collar when the clutch rotates
and when the
clutch stops. Check the wiring to the micro-switch and to
terminals 9, 10, 11, 20 & 21 on the PCB.If all else fails,
replace the PCB.
16.4 .... Trouble Shooting -
Machine Will Not Number
Sheets feed but will not number:- Release the upper sensor and
clean both lenses.
Check that the LED on the control PCB is not illuminated.
This indicator should only illuminate when paper is between
the upper & lower sensors, but it will also illuminate if the
sensors or their cables are damaged.
If the LED is illuminated, check the connections to terminals
4, 5, 6 & 7 on the PCB and check that these wires are not
shorting. Replace the PCB and / or the sensors.
If the LED is not illuminated, Check the security of the wires
to terminals 9, 10, 11, 14, 15 & 16 on the control PCB and
check the connections to the main clutch coil (red & black
wires).
Check the main clutch coil resistance which should be 10
Ohms and replace the coil if this is incorrect otherwise
replace the PCB.
If the clutch does not operate in 'manual' mode, check the
wiring between the auto / man switch on the side-cover and
terminals 16 & 17 on the PCB.
