4.1.58 The counter fails to operate.
Counter
1) Turn OFF the power switch, and disconnect the connector J2216
from the DC controller. Set the meter to the ×K
ΩΩ
ΩΩ
Ω range, and mea-
sure the resistance of the following counters:
Counter + –
CNT1 J2216B-9 J2216B-8
CNT2 J2216B-10 J2216B-8
CNT3 J2216B-11 J2216B-8
CNT4 J2216B-12 J2216B-8
CNT5 J2216B-13 J2216B-8
CNT6 J2216B-14 J2216B-8
NO: Check the wiring from J2216 to the counter; if normal, replace the
counter.

2) Connect the connector J2216, and set the meter to the 24VDC
range.
Does the voltage of the following connectors on the DC controller
PCB change from about 24 V to about 0 V and then to 24 V when
the Start key is pressed? Be sure to select a copying mode appropri-
ate to the counter operation:
Counter + –
CNT1 J2216B-9 J2216B-8

NO: Replace the DC controller PCB.
YES: Replace the counter.
