NOTES:
1. When the power sup ply v ol tag e drops to the low er l im it, the printer stops printing and
then starts printing on that line again more slowly than before.
2. When the head temperature rises to the upper limit, the printer stops printing. When
the head temperature falls to the normal level, the printer start printing again more
slowly than before.
3. Copy 1: When the paper thieckess lever is set to 2 or 3.

2.3.2 System Reset Circuit
Control circuits IC1 and IC2 are initialized when a /RESET si gnal (LOW
level) is output from port 5 (VOUT) of IC15. IC15 monitors the +5 V line
on port 2, and resets under the following condit ions:
1. When the power supply is turned on, a /RESET signal is output.
/RESET is canceled when the +5 V line goes up to 4.2 V, and then
100 ms passes.
2. When the +5 V line goes below +4.2 V, a /RESET signal is output.
/RESET is canceled when the +5 V line goes back up to 4.2 V and
then 100 ms passes.

2.3.3 Printhead Driver Circuit
The standard voltage for the A/D conv erter is made in ZD1 and input to
CPU port 78. Based on this standard voltage, the A/D converter in the
CPU operates. Port 74 monitors the +35 V line between R70 and R71 to
determine the printhead driver pulse width . Using the monitored
voltage, the CPU converts the voltage to a digital value and decides the
printhead driver pulse width, and then trans ports the data to the gate
array via CPU ports 15 and 19. Based on the monitored voltage, the
CPU decides the printing interval. Port 73 monitors the printhead
temperature to protect th e printhead. If the t emperature exceeds 107
° F), printing is stopped.

Figure 2-6. CR Motor Driver Circuit
The carriage motor driver circuit controls the CR motor, using an
open-loop, constant drive arrangement. 2-2 and 1-2 phases excite the
motor. One step of the 2-2 phase switching system corresponds to 2
steps of the 1-2 phase switching system. Ports 1, 8, 11, and 18 of the
SLA7024M are used to change the excitation phase, depending on the
selected print mode. Table 2-2 on the following page describes the
motor driver modes.
The SLA7024M (IC9) CR motor driver circuit detects and regulates the
amount of current flowing in the carriage mot or coil . The curr ent flowi ng
through the coil varies, depending on the speed of the CR motor. The
CPU sets the amount of current via the Address / Data line. Signals are
sent via ports 3 (RFA) and 14 (RFB) to the SLA7024M. The SLA7024M
sets the coil current, depending on the CR speed.

The EEPROM is controlled by CPU ports 9 (P70), 10 (P71), 11 (P72),
and 12 (P73). Port 11 is the data output line used to save the
information to the EEPROM, and port 12 is the data input line used to
read the saved data from the EEPROM. Port 70 is the chip select line,
and port 71 is the clock timing line. When the PWDN signal (power
down) is detected on port 20 (INTO), the CPU writes the necessar y data
to the EEPROM before the +5 V line drops to 4.75 V.

The CPU detects conditions of the following sensors: home posit ion
(HP) sensor, release sensors 1 and 2, pl aten gap (PG) sensors 1 and 2,
rear and front paper end (PE) sensors, paper width (PW) senso r, and
cover open sensor.
Two types of sensors are used in this printer. Release sens ors 1 and 2,
the PG sensors 1 and 2, the front PE sensor, and the cover open
sensor are momentary switches.
The other type of sensor i s used for the HP sensor, rea r PE sensor, and
PW sensor, which are photo diode switches. The HP sensor detec ts CR

The rear PE sensor detects that paper has been loaded when the photo

PE sensor. The PW sensor, used for paper width measurement and
paper loading positioning, detects the paper edge by comparing the
measured voltage with standard voltage, which was measured during
the power on sequence.
Additionally, as mentioned on the page 2-24 (LQ-2070 Servi ce Manual),
the +35 V line and head temperatures are monitored to set the pulse

chapter only includes information that is specific to the FX-980.
3.2 Printer Disassembly and Assembly
The assembly procedures to be explained for the FX-980 are as listed
below. (Note the heading numbers and figure numbers used in the FX2170 Service Manual are applied to this chapter.)
Section 3.2.10 Removing the Printer Mechanism
Section 3.2.10.3 Removing the Right Frame Assembly
Section 3.2.10.5 Removing the Left Frame Assembly

4.1 Overview
The adjustment items required for the FX-980 are the same as for the
FX-2170. Therefore, see Table 4-1 in the FX-2170 Service Manual and
perform any necessary adjustment after disassembling/assembling the
printer.
CAUTIO N
4.1.1 Pre-operation for the Adjustment Program
1. Load continuous paper. (80-column paper should be used to avoid
printing on the platen.)
CAUTIO N
Though the conditions for each adjustment are the
same as for the FX-2170, the adjustment program
used for the FX-980 is diff erent. Therefore, obser ve the
instructions given in the following sections.
Do not use cut sheet for the Bi-D adjustment. Since
the Bi-D adjustment has to be performed with the t op
and bottom edges of the sheet firmly set in the paper
path, use of cut sheet will not provide accurate
adjustment.
Use single continuous paper.
Adjustment program for serial dot matrix printer
does not run without any paper loaded. So, be sure
to turn the printer on first and then load paper.
NOTE: If you omit this operation, the printer will perform Uni-D
print instead of Bi-D.

4.1.2 Bi-D Adjustment
The value “0” shown in the screen shown in Figure
This adjustment is made after the main board or the CR motor has been
replaced. The purpose of this adjustmen t is to electrically correct the
head wire’s point of impact during Bi-D printing. The adjusted value is
stored in the specific addr ess in the EEPROM. Once the value is stored,
it will not be erased if the printer is turned off or the EEPROM is reset.
CAUTIO N
If the printer is in the emulation mode, characters
output for the Bi-D adjustment will be garbled. If so,
turn ESC/P2 on using the EEPROM Initi alization mode.
1. Perform the pre-operation. (See Section 4.1.1.)

6. When this adjustment is completed, if you need to perform another
adjustment using this program, you can continue wit hout turning off
the printer.
4.1.3 TPE Level Reset
Make this adjustment when the main board or Top PE Sensor has been
replaced. Generally, light level emitted from the photo diode in a photo
sensor lowers with age. For this reason, the printer renews the current
paper remaining level by detecting the black level of the platen each
time the printer is turned on or paper is fed. When the TPE level is reset,
FF is written and it approaches 00 as the t ime goes by. If this operation
is not performed, paper out condition may be detected despite paper is
set.
1. Perform the pre-operation. (See Section 4.1.1.)

waveform (CH1) at pins 6,
5, 17, and 16 of IC9.
• Check output signal
waveform (CH2) at pins 8,
1, 18, and 11 of IC9.
If the signal is
not correct,
replace the CR1
(or replace the
main board).
Otherwise,
replace IC2.
If the input
signal is not
correct, replace
IC2 (or replace
the main board).
If the output
signal is not
correct, replace
IC9.
Problem Cause Checkpoint Solution
Paper feed is
abnormal.
No data is
printed.
A particular
dot fails to
print.
IC1 is
defective.
IC12 is
defective.
IC2 is
defective.
IC1 is
defective or
one of the head
drive
transistors is
defective (Q2 Q19).
• Check input signal waveform at
pins 1, 2, 23, and 24 of IC12.
• Check output signal waveform
at pins 6, 3, 18, and 21 of IC12.
Check the output signal waveform
at pins 31 and 32.
• Check the voltage waveform
(CH1) at port HD1 - HD18 of
IC1.
• Check the voltage waveform
(CH2) at the collector or emittor
side of each transistor.
If the input
signal is not
correct,
replace IC1 or
IC2. If the in put
signal is
correct and the
output signal is
not correct,
replace the
IC12.
If this signal is
not output,
replace IC2.
If the head
drive signal is
not output,
replace IC1 (or
replace the
main board). If
the head drive
signal is
output, replace
the head drive
transistor.
