OPERATING PRINCIPLES Power-On Sequence 53
Confidential
2.2 Power-On Sequence
Initializing operations of this printer at power-on differ between when powered off
normally (
Simple Reset Sequence (p54)) and when powered off abnormally (All Reset
Sequence (p56)). This section describes how this printer operates in the Simple Reset
Sequence and in the All Reset Sequence under certain conditions.
From the next page on, simplified diagrams of the printer describe
operations in each sequence. The following shows how to use the
diagrams.
Printer Operation Status
Figure 2-6. Printer Operation Status
EJ Frame Assy
Carriage
Digit number of CR
PF Roller
PG Position
This shows "PG-".
CR Lock
Red: Set
White: Released
Position change of
EJ Frame Assy
This shows EJ Frame Assy
is rising.
EJ Release Trigger
PG position change by APG Mechanism
This shows the change from "PG++" to
"PG-".
Rotation Direction of PF Motor
Clockwise: forward feeding
Counterclockwise: backward feeding
This shows clockwise rotation.
Switch Lever
Shows carriage movement.
PF Drive Shift Status
In this printer, the PF Motor drives five different mechanisms. The
mechanism driven by the PF motor is switched by changing the position
of the Transmission Arm
(See Figure 2-6.)
using the PF Motor's drive
force while the carriage presses the Switch Lever to the 0-digit side
(Switching Position). The following shows how to use the simplified
diagram which indicates the relationship between the position of the
Transmission Arm and the mechanism driven by the PF motor.
Figure 2-7. PF Drive Shift Status
Note : In power-on sequences, there is no operation using positions (2) and (5).
This printer does not use position (3).
CDR Tray Drive Position
(1)
Shows the PF Motor's drive force is
transmitted to the CDR Tray movement
mechanism.
ASF Drive Position (2)
Shows the PF Motor's drive force is
transmitted to the paper loading
mechanism.
APG Drive Position (4)
Shows the PF Motor's drive force is
transmitted to the APG mechanism.
Photo Tray Drive Position
(5)
Shows the PF Motor's drive force is
transmitted to the cassette's photo tray
movement mechanism.
Ink System Drive Position
(6)
Shows the PF Motor's drive force is
transmitted to the Ink System.
Intermediate Position
The Switch Lever is in the Intermediate
Position, where the transmitted PF
Motor's drive force is cut off from each
mechanism except for the paper feeding
mechanism.
PF Drive transmission
path is changing.
(Switching Position)
Shows the Switch Lever is in the
Switching Position and the
Transmission Arm is shifting; in this
case, from position (6) to (1) by the PF
Motor's drive force.
