Check the periphery circuit of IC120, and replace it
if defective.
N.G.
When the periphery circuit is correct, replace
IC120.
Check the periphery circuit of JOG WHEEL form
N.G. IC120, and replace it if defective.
When the periphery circuit is correct, replace JOG
WHEEL.
N.G. Check periphery circuit of IC119 from IC120, and
replace it if defective.

N.G.
replace it if defective.
When the periphery circuit is correct, replace IC119.
