1.2.2.1 Usual Operation

In the normal mode, pressing panel switches executes the following functions;

Operate

(1)

This switch turns the printer on and off. It is the secondary switch in the power supply circuit.

CAUTION

Unplug the power cable from the AC Inlet when connecting/
disconnecting the Interface cable to/from the printer.

Pause

(2)

This switch alternates printer activity between printing and non-printing states.
If this button is held down for over 3 seconds when the printer is in the non-printing status, the
Micro Adjust function and Font selection are enabled. If it is pressed again, these function are
disabled.

Load/Eject

(3)

- Loads the paper when the printer is out of paper.

- Ejects the paper to the paper park.

LF/FF

(4)

- Feeds a line if pressed shortly.

- Feeds the continuos paper or eject the cut sheet.

Tear Off

(5)

Advances the continuos paper to the Tear-OFF position. If it is pressed again, the paper is
moved to the TOF position.

Bin

(6)

Selects the CSF bin number when the CSF is used.

Font

(7)

Selects the font from the list on the panel when the Micro Adjust function is enabled.

Micro Adjust

(8)

The Micro Adjust switch is available in the Micro Adjust mode.
Micro switch executes micro feed forward or backward by 1/216 inch one by one.
The TOF adjustment is enabled in the TOF position after loading the paper, and the Tear-off
adjustment is enable in the Tear-off position.

Chapter 2 Operating Principles

2.2 PRINTER MECHANISM

This printer mechanism consists of Printhead, Paper feed mechanism, Carriage movement
mechanism, Tractor feed mechanism, Platen gap adjustment mechanism, Ribbon feed
mechanism, PF motor, CR motor, detectors, and so on.

2.2.1 Printhead

The printhead prints data from the control board on paper using the ink ribbon. The printhead is
mounted on the carriage unit.

2.2.2 Paper Feed Mechanism

The paper feed mechanism picks up paper and transports it to the printhead, then ejects the paper
step by step or continuously driven by the PF motor. PF motor drives the paper feed mechanism
gears and the platen roller. The top of form and paper out condition are detected by the front and
rear PE detector, respectively.

2.2.3 Carriage Movement Mechanism

The carriage movement mechanism carries the carriage unit left and right along the CR guide
shaft and mechanism frame, and stops it at any position for printing. It is driven by torque sent
from the CR motor via the timing belt. Home position is detected by the HP (home position)
detector at power on and CR motor phase changing timing.

2.2.4 Tractor Feed Mechanism

The tractor feed mechanism feeds continuous paper to the printhead and ejects it. Torque from
the PF motor is transferred to the tractor unit via the release mechanism in the paper feed
mechanism. The release lever in the release mechanism switches torque from the PF motor
between cut sheet feeding and continuous paper feeding. This printer is equipped with several
tractor feeding methods (front / rear push tractor feeding, front / rear push & pull tractor feeding
and front / rear pull tractor feeding), which is selected according to the tractor unit setting positions
and the lever positions. The tractor detector detects the release lever setting position, for cut sheet
feeding or continuous paper feeding.

2.2.5 Platen Gap Adjustment Mechanism

The platen gap (the gap between the platen and the printhead) adjustment mechanism consists of
CR guide shaft, parallelism adjustment bushing, PG adjust lever and PG detector. PG adjust lever
is attached to the left side of the CR guide shaft. The bushings are attached to the both sides of
the frame. As the both sides of CR guide shaft are eccentric toward external form of them,
printhead approaches or recedes from the platen roller as the PG lever turns forward or backward.
PG detector detects PG lever position. If the lever is set to a position between “2” and “6”, the
printer is in the copy mode.

2.2.6 Ribbon Feed Mechanism

The CR motor drives the ribbon feed mechanism via the timing belt. The ribbon feed mechanism
has the sun and planetary gear system. No matter the carriage unit is driven left and right, the ink
ribbon is driven in one direction.

2.3 CIRCUIT OPERATION

2.3.1 C229PSB/PSE/PSH Power Supply Circuit

This printer can be powered by one of the following three power supply boards: the C229PSB
(120V) board, the C229PSE (230V) board, or the C229PSH (Universal) board. The function of the
boards is the same , except for a difference in the primary circuitry. The power supply outputs the
DC current necessary to drive the printer control circuit and drive the mechanism. The input
voltages and fuse ratings are as shown in the following table:

Table 2-1. Input Voltage and Fuse Rating

Board Input Voltage Fuse F1 Rating

C229PSB 85-138VAC 4A, 125V or 250V
C229PSE 187-276VAC T2.0AH, 250V
C229PSH 85-276VAC T4.0AH, 250V

The power supply circuit outputs voltages used to drive the various control circuits and the
mechanism, as shown in the following table:

Table 2-2. Output Voltages and Applications

Output Voltage Applications

5Vp5% 0.7A Logic lines
(Type-B I/F output is included.) Detectors

Panel Switches & LEDs

35Vp6% 0.8A CR Motor

PF Motor
Printhead

The power supply circuit consists of the line filter circuit, ZC-RCC (Zero-Cross Ringing Choke
Converter) switching circuit and 5V chopper regulator IC. The AC voltage is first input to the line
filter circuit for higher harmonics absorption, then input to the switching circuit and transformed to
+35VDC. +5VDC is generated from +DC35V by the regulator IC. The over current / voltage
protection circuit is also designed on the board.

panel.

This section describes procedures for disassembling and assembling the printer. Unless otherwise
specified, disassembled units or components can be re-assembled by reversing the disassembly
procedure. Therefore, no assembly procedures are included in this section. Precautions for any

WARNING

CAUTION



Before disassembling, assembling or adjusting the printer,



disconnect the power supply cable from the AC power socket.
Failure to do so might cause personal injury.



Be careful with the printhead when you handle it as it may be very



hot right after printing.



Do not touch the heat sink attached to the switching FET (Q1) on the



power supply board right after power off, as it may be very hot.



Never touch the heat sink attached to the switching FET (Q1) while



The AC power cable is connected to the AC outlet, as it is not
electrically isolated.

To maintain efficient printer operation, take the precautions below:



Use only the recommended tools for maintenance work.




Use only the recommended lubrications and adhesives (See Chapter



6.)



Adjust the printer only in the manner described in this manual.




Be aware that the existing drawings for Fx-880 are substituted for



FX-1180. It is because no exclusive drawings for FX-1180 has been
made since the major mechanical difference between FX-1180 and
FX-880 is width only.

order:

1. Remove the Upper Housing. (See Section 4.2.4.)

2. Remove the printhead from the carriage assembly. (See Section 4.2.1.)

3. Using tweezers, remove the ribbon mask from the carriage assembly.
