CHAPTER 5 TROUBLESHOOTING IMAGE FAULTS/MALFUNCTIONS
5-143
4.1.34 E517
a. E517-0001 through -0005
Solenoid
1) Disconnect the connector of the upward curl removing solenoid
(SL5/6), and the solenoid side for electrical continuity. Is there con-
tinuity?
YES: Go to step 2.
NO: Replace the solenoid without electrical continuity.
Sensor
2) Try replacing the upper phase sensor (PS4/5). Does the error disap-
pear?
NO: Replace the buffer pass driver PCB.
b.E517-0006 through -0009
Cable
1) Are the connectors (J101 through 103; 201 through 205; 301
through 303) on the buffer pass driver PCB connected correctly?
NO: Connect them correctly.
2) Disconnect the connector of the sorter. Doe the error disappear?
YES: Check the cable between the sorter and the buffer pass.
NO: Go to step 3.
3) Try replacing the buffer pass drive PCB. Is the problem corrected?
YES: Replace the buffer pass drive PCB.
NO: Check the cable between the buffer pass and the copier.
4) Is the cable between the buffer pass driver PCB and the following
sensors connected correctly: inlet sensor (PS8), reversal timing sen-
sor (PS1), reversal jam sensor (PS2), upper phase sensor (PS4/5),
and lower phase sensor (PS6/7)?
NO: Connect it correctly.
c. E517-0011 through -0015
1) Disconnect the connector of the downward curl removing solenoid
(SL7/8), and check the solenoid side for electrical continuity. Is
there continuity?
YES: Go to step 2.
NO: Replace the solenoid without continuity.
2) Try replacing the lower phase sensor (PS7/7). Doe the error disap-
pear?
NO: Replace the buffer pass driver PCB.
