2-2. Operation of Control Parts
CLP-621 & CLP-631
2-32
(4-5) Fan driver
This circuit drives the ribbon motor cooling fan.
When pin 130 (FANCTL) is set to “Low” level, TR5 turns ON and the fan is driven.
The fan is driven according to the Ribbon Motor F temperature detected by the ribbon
motor temperature sensor.
When the temperature is under 45
°
C (113
°
F), the fan is not driven.
When the temperature exceeds 45
°
C (113
°
F) during ribbon motor running, the fan starts to
turn.
If the temperature is 70
°
C (158
°
F) or more after the ribbon motor is stopped, the fan is kept
turned until the temperature falls under 70
°
C (158
°
F).

(5) Other circuits
(5-1) +3.3V/+1.5V circuit
The Main PCB re5V and +24V from the Power Supply Unit. +5V and +24V are
used for control circuits and driver circuits, respectively.
IC15 and IC16 are the regulator ICs to p3.3V and +1.5V from +5V.
+3.3V is used for various logic circuits. +1.5V is supplied to the CPU (IC1) only.
