FLOW CHART NO.15 (704-6K2-A615 CONRTOL 1 PCB ASS'Y)
JOG WHEEL is not operating
(SCRATCH function is not operating)
Is BEND function operating?
YES
Is reference waveform outputted at 2pin, 6pin and 12pin of
IC106 and IC111?
(See Fig.1-7-1 of the 52 page.)
When JOG WHEEL is touched, is wavelength of 2pin, 6pin
and 12pin changing of IC106 and IC111?
(See Fig.1-7-2 of the 52 page.)
Is waveform inputed to 2pin of IC104 and 5pin of IC110?
(See Fig.1-7-3 of the 52 page.)
Replace IC100.
When the top of JOG WHEEL is touched, is waveform inputed
to 20pin and 28pin of IC100 changed?
YES
YES
YES
YES
NO
See FLOW CHART NO.14 <JOG WHEEL is not
operating. (BEND function is not operating.)>.
NO
Check the surrounding circuit of IC106 and IC111 and rreplace
any faulty parts.
When the surrounding circuit is correct, replace IC106 and
IC111.
NO
Check the surrounding circuit of JOG WHEEL form IC106
and IC111 and replace any faulty parts When the surrounding
circuit is correct, replace JOG WHEEL.
NO
Replace IC104 and IC110.
NO
Check surrounding circuit of IC100 from IC104 and IC110,
and replace any faulty parts.When the surrounding circuit is
correct, replace IC104 and IC110.
