Unit Repair C209 MAIN Board
This section describes the problems related to the main controller board(C209 MAIN). The table below
provides various symptoms, likely causes, and checkpoints. The check points refer to waveforms,
resistance, and other values to be checked to evaluate the operation of each component.
Table 5-7. Repair of the C209 MAIN Board
Symptom
Condition
Cause
Checkpoint
Solution
The printer
does not
operate at all.
CPU does
not operate.
The reset
circuit is
defective.
Check the waveform of
the +5V and /Reset signal
(IC8=5,1-pin)
Replace IC8
Control ROM is
not selected
correctly or it’s
dead.
Check if the signal
waveform at 11 pin of the
IC3 can be reversed High
or Low.
Replace IC3.
RAM is
defective.
Replace RAM.
CPU is
defective.
Check the clock waveform
at 27 or 28-pin of IC1.
Replace IC1 if
the oscillation
waveform is
normal, if it is
abnormal,
replace the
oscillator CR1.
The carriage
does not
operate
normally.
Carriage
motor does
not operate
at all.
IC2 is defective.
Check the signal
waveform at 1, 2, 23 and
24 pin of IC14.
Replace IC2.
IC14 is
defective.
Check the signal
waveform at 3, 6,or 18, 21
pin of IC14.
Replace IC14.
