2. IC protectors replacement
ICPs (IC Protectors) are installed to protect the TX motor drive circuit
and verification stamp drive circuit. ICPs protect various ICs and elec-
tronic circuits from an overcurrent condition.
The location of ICPs are shown below:
(1) F100 (ICPS10) is installed in order to protect IC’s from and
overcurrent generated in the verification stamp drive circuit. If F100
is open, replace it with a new one.
(2) F101 (ICPS18) is installed in order to protect IC’s from an overcurrent
generated in the TX motor drive circuit. If F101 is open, replace it
with a new one.
In addition to the replacement of F101 and F100, the factor causing
F101 and F100 to open must also be repaired. If not, F101 and
F100 will open again.
