3.1 U1:MOTOR FAIL

There is a problem with the Motor Assy Main.
Step
1
INITIAL ANALYSIS
Inspect the following components.
• Motor Assy Main (PL8.1.14)
• PWBA HKB26 MCU (PL10.1.13)
• Gear Assy Drive (PL8.1.13)
• PWBA HKB PS (PL10.1.17)
Are they compatible with your printer version, correctly
installed, not damaged, deformed, or contaminated?
2
MOTOR ASSY MAIN ANALYSIS
Use MAIN MOTOR TEST to check the Motor Assy Main
(PL8.1.14).
Does the Motor Assy Main run?
3
MOTOR ASSY MAIN (PL8.1.14) ANALYSIS
1. Remove the Motor Assy Main from the Gear Assy Drive
(PL8.1.13). Do not unplug the Motor Assy Main from the
PWBA HKB26 MCU (PL10.1.13).
2. Use MAIN MOTOR TEST to check the Motor Assy Main.
Does the Motor Assy Main run?
4
MOTOR ASSY MAIN (PL8.1.14) ANALYSIS
Check the voltage between P/J291-9 <=> P/J291-6, P/J291-8
<=> P/J291-5 and P/J291-7 <=> P/J291-4.
Is there +24VDC between P/J291-9 <=> P/J291-6, P/J291-8
<=> P/J291-5 and P/J291-7 <=> P/J291-4 on the Motor Assy
Main?
5
PWBA HKB26 MCU (PL10.1.13) ANALYSIS
Check the voltage between P/J29-1 <=> P/J29-4, P/J29-2 <=>
P/J29-5 and P/J29-3 <=> P/J29-6.
Is there +24VDC between P/J29-1 <=> P/J29-4, P/J29-2 <=>
P/J29-5 and P/J29-3 <=> P/J29-6 on the PWBA HKB26
MCU?
6
PWBA HKB PS (PL10.1.17) ANALYSIS
Check the voltage between P/J281-1 <=> P/J281-4, P/J281-2
<=> P/J281-5 and P/J281-3 <=> P/J281-6 on the PWBA LVPS
Is there +24VDC between the each P/J281-1 <=> P/J281-4,
P/J281-2 <=> P/J281-5 and P/J281-3 <=> P/J281-6 on the
PWBA HKB26 MCU?
