2.3.2 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 R139 and R140
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 port 15. Based on the monitored voltage, the CPU
decides the printing in terval. Port 73 monitor s the printhead temper ature
to protect the printhead. If the temperature exceeds 95
° C (213° F),
printing is stopped.

The carriage motor driver circuit controls the CR motor, using an
open-loop, constant drive arrangement. 2-2, 1-2, and W1-2 phases
excite the motor. A 2-2 phase step is equivalent to a 1-2 phase step
doubled. 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
in the following page describes the motor driver modes.
The SLA7024M (IC11) CR motor driver circuit detects and r egulates 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 and signa ls are sent via ports 32 to port
35. The SLA7024M sets the coil current, depending on the CR speed.

Two types of sensors are used in this printer. Rel ease senso rs 1 and 2,
the PG sensors, and the front PE sensor are momentary switches.
The HP sensor, rear PE sensor, and PW sensor are photo diode
switches. The HP sensor detects CR home position when the photo
diode rays are cut off by the printhead. The rear PE sensor detects that
paper has been loaded when the photo diode rays are cut off by the
sensor plate, which is included in the rear 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, the +35 V line and head temperatures are monitored to set
the pulse length of the head driver signal.

LQ-2080 Revision A
4.1 Overview
The adjustment items required for the LQ-2080 are the same as for the
LQ-2070. Therefore, see Table 4-1 in the LQ-2170 Service Manual and
perform any necessary adjustment after disassembling/assembling the
printer.
CAUTION
4.1.1 Pre-operation for the Adjustment Program
1. Get a continuous paper. (136-column pap er should be us ed to avoid
printing on the platen.)
CAUTION
Though the conditions for each adjustment are the
same as for the LQ-2070, the adjustment program
used for the LQ-2080 is different. Therefore, observe
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.
CAUTION
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.)
2. Select “1. Bi-D Adjustment”. The following screen appears.

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.

selected.
Check the voltage
waveforms of the V CC signal
(CH1: IC2 pin 3) and VOUT
signal (CH2: IC2 pin 1) when
power is turned on.
Check for a change in the
signal from HIGH/LOW at pin
22 of IC10.
Replace IC2.
Replace IC10
(or replace the
main board).
NOTE:This information is necessary only for servicers who repair to
the component level. Servicers who repair to the unit lev el
