When the power supply voltage drops to the lower limit, the printer stops
printing, and then starts printing again on the same line at a slower speed.
When the print head temperature rises to the upper limit, the printer
stops printing. When the head temperature returns to the normal level, the printer starts printing again at a slower speed.

If the printing on the bottom copies of your thick multi-part forms is faint, turn on the double-strike mode as described below. In the double-strike mode, the printer prints draft and bitmap images using double-strike printing. The printer does not use two-pass printing in this mode.
Note:
The double-strike mode is available only when the paper thickness lever
is set to position 4 or higher and the paper release lever is set to the pull tractor position.
Always turn on the double-strike mode before printing on multi-part
forms with seven parts. Use double-strike mode only under normal temperature and humidity
conditions. When the printer is in the double-strike mode, the print speed is
reduced.

OPERATING PRINCIPLES
&+$37(5
EPSON FX-2180 Service Manual Chapter 2 Operating Principles

2.1 Overview

The printer’s main components include the printer mechanism, power supply circuit, control circuit, control panel, and housing. This chapter describes the operating principles of the main components.

2.1.1 Printer Mechanism

The printer mechanism consists of the following parts: Print head
The print head prints dots on paper using the ink ribbon. Print data comes from the control circuit.
Carriage mechanism
The main parts of the carriage mechanism are the carriage unit, carriage (CR) motor, timing belt, driven pulley, and CR guide shaft. The carriage unit contains the print head. The carriage mechanism moves the carriage unit along the CR guide shaft between the left and right ends of the printable area.
Platen gap mechanism
The platen gap is the gap between the platen and the print head. You adjust the platen gap to maintain print quality when using paper of different weights or thicknesses. The platen gap mechanism consists of the CR guide shaft, the platen gap adjustment bushing, and the platen gap (PG) adjustment lever. The platen gap mechanism moves the print head toward or away from the platen, depending on the position of the PG adjustment lever.
Paper feed mechanism
The main components of the paper feed mechanism are the paper feed (PF) motor, the rear or front tractor, and the platen. Using the PF motor, the paper feed mechanism picks up continuous or single-sheet paper, moves it to the print head for printing, and ejects it from the printer after the page has been printed.
Disengage mechanism
The disengage mechanism consists of two disengage gears. It switches the paper feed torque from the PF motor to the tractor(s) or the paper feed rollers depending on the selected paper feed method (friction, front push tractor, rear push tractor, pull tractor, or push-pull tractor feeding).
Ribbon advance mechanism
The main components of the ribbon advance mechanism are the ribbon feed roller and the driven pulley. The ribbon advance mechanism winds the ink ribbon in one direction. This allows the printer to use a fresh ribbon surface for printing.

2.1.2 Power Supply Circuit

The printer can be powered by one of the following three power supply boards: C166 PSB (120 V), C166 PSE (220 – 240 V), or C244 PSH (120 V / 220 – 240 V). The boards function in the same way, except each board has a different primary circuit. The table below lists the input voltages and fuse ratings of the boards.
circuit removes the noise. Then the AC voltage undergoes full-wave rectification and is smoothed to produce direct voltage. In the C244 PSH board, the AC voltages undergo voltage doubler rectification in the automatic switching IC and are smoothed to produce direct voltage. The voltage is fed to the gate port for switching FET Q1 through resistors R18 and R31. Then the switching circuit operates.
Table 2-1. Power Supply Board

2.1.2.1 Power Supply Circuit Operation
The power supply board has two DC power outputs: one for the control circuit and one for the printer mechanism. The table below lists the applications of the output voltages.
