Checks
Are the connector J213 on the DC
controller PCB, connectors J641,
J642, J643, and J647 on the printer
side main relay PCB, connectors
J671 and J672 on the sub relay
PCB, connector J1302 of the hold-
ing plate solenoid, and connector
J102 of the power supply connected
securely?
Does the voltage between the con-
nectors J1301-2 (+24 UH) and
J1301-1 (GND) on the multifeeder
tray PCB change from 0 to 24 V?
Is +24 UH present on the multifeed-
er tray PCB and the holding plate
solenoid?
Disconnect the connector J1302 of
the holding plate solenoid from the
multifeeder tray PCB. Measure the
resistance between the connectors
J1302-1 (MPTSLD*) and J1302-2
(+24 UH) on the harness side. Is it
about 160 Ω?
