Confirmation Tasks
By visual inspection, please check whether
incompletely connection and oblique insertion of
connector or defective cable assembly exists
Check whether wire gnawing occurred during
assembly of equipment.
Pull the HOP connector of main board (M32 PCB) out,
check the followings on the cable connector.
Short circuit between 1pin-FG
Short circuit between 2pin-FG
Short circuit between 3pin-FG
Short circuit between 4pin-FG
Pull the HOP connector of the main board (M32
PCB) out, check whether the resistance values
between 1pin-2pin and 3pin-4pin are about 3.5Wor
4.4Wrespectively on the cable side.
By using the motor clutch test function of the
maintenance utility, check whether paper feed solenoid
operates normally.Remove the sheet metal of the right
side in order to check whether the solenoid can be
seen.
Check whether the parts that may disturb the operation
of moving parts of the solenoid exist (cable etc).
please check whether incompletely connection and
oblique insertion of connector or defective cable
assembly exists.
