2.1 PRINTER MECHANISM OPERATION This section describes the printer mechanism and explains how it works. 2.1.1 Printing Mechanism The printing mechanism is composed of the printhead, ink ribbon, and ribbon mask. The printhe ad is an 18-pin (9 pins × 2) head for impact dot printing.
2.1.2 Carriage Movement Mechanism The carriage movement mechanism consists of the carriage assembly, carria ge (CR) motor, timing belt, driven pulle y, home position (HP) sensor, etc. The CR moto r drives the timing belt. The carriage assembly is connected to the timing belt , which is moved by the CR motor.
2.1.3 Platen Gap Adjustment You can adjust the platen gap (the gap between the platen and printhead) to allow the printer to use paper of different weights or thicknesses. When you move the platen gap adjust leve r forward or backward, the carriage guide shaft rotate s.
2.1.4. Paper Handling Mechanisms During the normal opera tion, paper is fed to the printer, advan ced to the specified position, and ejected from the printer. These paper-handling operations are performed by various paper handling mec hanisms, such as tractors, platens, rollers, and gears.
2.1.4.2. Paper Advance Mechanism This section describes how the friction and trac tor advance mec hanisms work to move the paper through the printer. 1. Friction Advance Me thod Paper is held betwe en the platen and the pape r guide rollers and betwee n the paper tension roller and paper tension unit cove r.
2. Push Tractor Me thod The push tractor method is used with the rear or front entranc e. When the push trac tor method is used with the rear entrance, the torque gene rated by the PF motor is transmitted to the push tractor gear through the PF motor pinion gear, paper advance reduction gear, and tractor reduction gea r.
Figure 2-7. Push Tractor Operation Using the Front Paper Entrance FX-2170 Service Manual Operating Principles Rev.A 2-7.
3. Pull Tractor Method The pull tractor advances paper in basically the same way as the push tractor. The push tractor is installed at the paper entrance and pushes pape r into the printer. On the other hand, the pull tractor is installed at the paper exit and pulls paper out of the printer mechanism.
4. Push-Pull Tractor Method The push-pull tractor meth od is a combination of the push and pull tractor methods. Two tracto rs are used to advance the paper: one at the front paper entra nce and the other at the rear paper entrance . They operate simultaneously to push and pull the paper through the printer mechanism.
Figure 2-10 Push-Pull Tractor Operation Using the Front Paper Entrance Operating Principles FX-2170 Service Manual 2-10 Rev.A.
2.1.5 Paper Paths This section describes various paper paths through the printer me chanism. These paper paths are divided into four groups, depending on which entrance (top, rear, bottom, or front) is used to feed paper. The printer has two PE (paper end) sensors.
2. Rear Entrance Figures 2-13, 2-14, and 2-15 show the paper paths for tractor feeding using the rear entra nce. You can use the rear entrance with any of the following paper feed metho ds: push tractor feed, pull tractor feed, or push-pull tractor feed.
Figure 2-15. Push-Pull Tractor Feeding Using the Rear Entrance As shown above in Figure 2-15, when you use the pull tracto r with this printer, you must remove the paper eject cover, which includes the pape r tension roller, from the printer mec hanism.
4. Front Entrance Figures 2-17 through 2-20 show the pape r paths for the front entrance. The front entrance can be used with any of the followi ng paper feed met hods: friction feed, push trac tor feed, pull tractor feed, or push-pull tractor feed. When the front entrance is used, the front PE sensor detects when paper is out.

2.1.6 Ribbon Adva nce Mechanism The ribbon is held between the ribbon advance roller (ribbon driven gear) and the ribbon pressure roller. When the carriage moves from left to right and vice versa on the CR guide shaft, the timing belt turns the belt-driven pulley.
2.2 POWER SUPPLY OPERATION The printer can be powere d by either of two power supply boards: the C166 PSB (120 V) or C166 PSE (230 V) power supply. These boards are the same for both the LQ-2170 and FX-2170. Additionally, the PSB and PSE boards function the same, exce pt for a difference in primary circuitry.
2.2.2 Power Supply Circuit Operation The power supply circuit is composed of an RCC (ringing choke converter) system and the power switch circuit in the secondary circuitry. The power supply circuit has several protection and control circuits. This section describes these circuits.
3. +35 V Constant Voltage Control Circuit The +35 V constant voltage control circuit is illustrated below. The constant voltage control circuit operates to keep the 35 V line at 35 V ± 6 %. When the voltage betwe en ZD51 and ZD85 becomes 32.7 V ± 2.
5. +35 V Line Over Current Protection Circuit The +35 V line over current control circuit is illustrated bel ow. When the +35 V line becomes less than 27 V, Q82 and Q54 turn on, and PC1 turns on. Consequently, Q32 and Q31 turn off, and then switching FET Q1 shuts off.
7. +5 V Line Constant Voltage Control Circuit The +5 V line constant voltage cont rol circuit is shown below. Port 16 of IC51 (TL494CN) monitors the + 5 V line, and the volta ge is compared with the standa rd voltage, which is input into port 15. Whe n the voltage of port 16 goes below 4.
2.3 CONTROL CIRCUIT The control circuit consists of the C166 MAIN board assembly and C165 PNL board This section describes the major compon ents and explains how the boards work. 2.3.1 Overview of Control Circuit Operation The printer’s control circ uit includes a TMP96C041AF CPU that runs at 14.
The following figure shows the data flow from the host computer to the printhead. Data sent from the host computer is converted to image data and transmitted to the printhead through the gate array. The following table lists the eac h function of the main components of the C166 MAIN board.
2.3.2 System Reset Circuit Control circuits IC1 and IC2 are initialized when a RESET signal (LOW level) is output from port 1 (VOUT) of IC10. IC10 monitors the +5 V line on port 3, and resets under the following condi tions: 1. When the power supply is turned on, a RESET signal is output.
2.3.4 CR Motor Driver Circuit The CR motor driver circ uit is shown below. The carriage motor driver circuit controls the CR moto r, using an open-loop, constant drive arrange ment. 2-2 and 1-2 phases excite the motor. A 2-2 phase step is equivalent to a 1-2 phase step double d.
2.3.5 PF Motor Driver Circuit The figure below shows the PF motor driver circuit. The gate array receives phase data from the CPU via ports 5 (PG10), 6 (PG11), 7 (PG12), and 8 (PG13), converts the data to UDN2917 form, and then sends that phase data to ports 43 (PH1) and 26 (PH2).
2.3.7 Sensor Circuits The CPU detects conditions of the following sensors: home position (HP) sensor, rele ase sensors 1 and 2, platen gap (PG) sensors 1 and 2, rear and front paper end (PE) sensors, paper width (PW) sensor, and cover open sensor. Two types of sensors are used in this printer.

4.2 ADJUSTING AND RESETTING THE PRINTER 4.2.1 Platen Gap Adjustment If you have rotated or reassembled the rear CR guide shaft or parallelism adjustment bushing, or if printing is light or dark, eve n at the proper PG lever position, perform this adjustment at 3 positions: the 5th, 80th, and 130th columns.
9. Insert a thin screwdriver into the drilled hole, located at the right edge of the rear CR guide shaft and adjust the platen gap by moving the screwdrive r to forward or backward until the gap is large enough for a 0.36 mm thic kness gaug e but too narrow for a 0.
4.2.2 Bidirectional Print Alignment Adjustment This section describes the procedure for adjusting the bidire ctional print alignment, required after mech anism repair. This procedure is also nece ssary if you replace the main board assembly or EEPROM, because the adjusted value is written to the EEPROM on the C166 MAIN board.
10. Highlight the mode by moving the cursor with the ↑ or ↓ key, and then print the current Bi-d print alignment patt ern for that mode by pressing SPACE . 11. If the Bi-d pattern is not aligned properl y, adjust it by changi ng the value with the ← or → key.
4.2.2.2 Bi-d Print Alignment Adjustment from the Control Panel 1. Turn the printe r on while pressing the PAUSE button to put the printer into Bi-D adjustment mode. 2. The printer prints out a guide sheet, cont aining 25 patterns in Super Draft mode. 3.
4.2.3 Factory Settings This section describes the procedure to reset factory settings, which is necessary if the mai n board or EEPROM is replaced. You can perform this procedu re only with the Settings Diskette . Notes: • After you select factory settings in the Setting File menu, be sure to run the check program in the Main Menu.
4.2.4 TPE Level Reset This section describes the procedure to reset the TPE (top paper end) level. This operation is required when the PW sensor assembly is replaced, and if it is not performed, the printer does not recognize that the PW sensor has been replaced, thus, limiting the ability of the new sensor to operate.
