temperature, so printing must be performed under the
conditions described in the table below.

Copy capability and paper thickness:

Glued ponion

Paper feed direction

Confidential

Normal paper (single-ply): 0.09 to 0.2 mm (.0035 to .0079")
Carbon copy paper

combination:
Pressure sensitive paper: 5 sheets maximum [original + 4 copies, at 20° to 45°C

Note:

When using multi-ply paper that consists of an original and three copies, be sure to print with a 9 × 9
font. If a 7 × 9 font is used, some characters on some of the copies may not be readable.

In the same way, when printing Kanji characters which consist of many lines, be sure to consider that
some of characters may not be readable regardless of number of the copies.

Notes on slip paper

Notes:

❏ The slip paper must be flat, without curls or wrinkles, especially at the top edges.

Otherwise, the paper may rub against the ribbon and become dirty.

❏ There must be no glue on the bottom edge of slip paper. Choose slip paper carefully

when the glue is on the right or top edge, since paper feeding and insertion are affected
by gluing conditions (e.g., glue quality, method, and length) and glue location (refer to
the illustration below titled “Slip paper glued area”). Be especially careful when slip
paper is wide and has the glue on the left edge, since skewing may occur.

5 sheets maximum [original + 4 copies, at 20° to 45°C
(68° to 113°F)]

(68° to 113°F)]

❏ Since the slip insertion sensor uses a photo sensor, do not u se pap er that has hol es at the

sensor position, or is translucent (refer to the illustration in the next section titled “Slip
sensor position”).

❏ Since the slip ejection sensor uses a refl ective photo sensor and it detects from the back of

slip paper, do not use paper that has holes or dark portions with low reflection (less than
40% reflection) at the sensor position (refer to the illustration in the next section titled
“Paper holes and low reflection prohibited area”).

❏ Use thinner paper (N30 or equivalent) between the top and bottom sheets of multi-ply

paper. If thick paper is used, the copy capability is lowered.

Notes on setting DIP switch 2-1 to ON

The printer mechanism stops but does not become busy when: an error has occurred, the cover
is open, printing stops due to a paper-end, or paper is fed using the paper feed switch.

When setting DIP switch 2-1 to ON to enable handshaking with the printer , be sure to check t he
printer status using the GS a command and the ASB function. In this setting, the default value
of n for GS a is 2. The printer automatically transmits the printer status, depending on on-line/
off-line changes.

When using DLE EOT and DLE ENQ, be sure that the receive buffer does not become full.
❏ When using a host that cannot transmit data when the printer is busy:

If an error has occurred, DLE EOT and DLE ENQ cannot be used when the printer is busy
due to a receive buffer-full state.

❏ When using a host that can transmit data when the printer is busy:

When the receive buffer becomes full while transmitting bit-image data, DLE EOT or
DLE ENQ used while sending the bit-image data is processed as bit-image data. The data
transmitted when the receive buffer is full may be lost.

Example: Check the printer status using GS I or GS r after transmitting each line of data

Rev. A Features and General Specifications 1-25

and use the 4K byte receive buffer. Transmit one line of data so that the receive
buffer does not become full.

Paper Sensors

The printer has 4 paper sensors as follows:

Slip:

• TOF (Top of Form) sensor

• BOF (Bottom of Form) sensor

Receipt:

• Paper roll near-end sensor

• Paper roll end sensor

Sensors and LED Indicators

1. Paper roll near-end sensor

The near-end sensor is located on the roll paper supply device on the receipt side. It detects
the near-end of the paper roll by detecting the paper roll diameter.

2. Paper roll end sensor

The paper sensor is located in the paper path on the receipt side. It detects the presence of
paper from the paper roll in the paper path of the printer mechanism.

When there is no paper in the paper path (paper end status), the PAPER OUT LED indica t or
lights.

1-34 Features and General Specifications Rev. A

TM-H5000II Series Technical Manual

Confidential

3. TOF sensor

The slip insertion sensor is located in the slip paper path and detects the presence of slip
paper in the pa per path. The SLIP LED indicator lig hts accordin gly.

4. BOF sensor

The slip ejection sensor is located in the slip entrance and detects whether the paper is set
correctly and whether it is removed or not. The printer does not proceed to the next
operation until the paper has been removed. (The SLIP LED indicator continues blinking.)

Sensors and Printing

When the printer detects a paper near-end, it either stops or continues printing depending on
the ESC c 4 setting. The corresponding sensors are as follows:

The paper roll near-end sensor is en abled only when pa per rol l i s se lect ed as the p rint sheet and
the slip BOF and TOF sensors are enabled only when slip is selected as the print sheet.
However, since the paper roll end sensor is used for paper-end detection, the printer stops
printing. Use the paper roll near-end sensor for detecting a roll paper end, and also use the
paper roll end sensor, if necessary.

The printer behaves as follows in the paper-end state:

1. When the receipt is selected

When printing stop is enabled, the paper roll near-end sensor detects a paper near end and
the printer automatically goes off line after printing the line being printed when the paper
near end is detected. To restart printing, load the paper and set the printer back on line by
closing the printer cov er . The pr int er star ts i n it ia li zi ng a nd c onti nues pri n ti ng data stored in
the print buffer.

2. When the slip is selected

When the slip BOF sensor is selected for printing stop, the slip BOF sensor detects a paper­end and the printer prin ts dat a up to the end o f the prin table ar ea, ejec ts the sli p when a ll the
next print dat a are transmitte d, and then waits for the slip to be removed. Afte r the slip is
removed, the printer enters the paper waiting state.

When the slip TOF sensor is selected for printing stop, the slip TOF sensor detects a paper­end. Then the slip TOF sensor ejects the slip when all the next data are transmitted with the
status of reverse paper feed until the paper is removed from the print head.

Printer Cover Sensors

Cover Open Sensor in the Slip Section

The sensor detects opening/closing of the front cover. When the cov er op en i s det ect ed, the
printer releases the print platen immediately and stops the carriage movements. The printer
goes off line automatically. The printer is in the recovery error state and the error LED
blinks.

Rev. A Features and General Specifications 1-35

The printer goes on-line by closing the front cover. Even i f the front cover i s closed, the err or

Confidential

LED blinks. The printer can recover by sending an error recovery command. If the printer
continues printing, it starts printing the beginning of the line it was printing when the front
cover was opened. In this case, printing position may shift; therefore, it is recommended to
initialize the printer and resend the print data.

Opening/Closing the Front Cover of the Slip Section

The cover can be opened by pulling a hook on the left of the cover toward you. When you
close the cover, push the cover backward.

When the cover open is detected by the cover open sensor, the printer releases the print
platen and stops carriage movements. If the front cover is opened during printing, data
lines are cut. Be sure not to open the front cover.

Cover Open Sensor in th e Receipt Section

The cover-open sensor monitors the printer cover. When the sensor detects a cover open, the
printer automatically goes off line and stops printing. The error LED (automatic recovery error)
blinks when the cover is open. When the printer cover is closed, the error LED goes off and the
printer goes on line and starts initializing automa tically and begins printing at the begin ning of
the line it was printing when the cover was opened.

Note:

Whether the cover is open or not does not affect the status reported by the paper roll end detector.

Opening/Closing the Cover in the Receipt Sect ion

When the cover open button is pressed, the printer cover is opened. When the cover is closed,
the cover open button is latched.

CAUTIONS:

Be sure to use the cover open button to open the printer cover.
Because the printer mechanism is re initialized after the printer cover is opened and

closed, the cover must not be opened during printing or an incorrect pitch may be
caused. Opening the cover during the auto-cutter operation may damage the printer.

Printing operation

Wire operation for printing of one dot

1. Application of the prescribed pulse to the drive coil causes its ferrite core to become
magnetized, which pulls the act uator plate in the direction of a rr ow (a) i n Fi gur e 2.4.3. Since
the dot wire is being pushed by the actuator plate with a force that is stronger than the
spring force of the wire return spring, the wire is pushed in the direction of the platen
assembly in the direction of arrow (b).

2. The dot wire is pr essed through the ink ribbon and paper int o the platen sub-assembly, and
prints a single dot.

3. When energizing of the drive coil is ended, the dot wire and actuator plate are returned to
their home positions by the wire return spring and the actuate plate spring.

Home position sensor mechanism

The home position sensor mechanism establishes the left side stroke of the head carriage
assembly. This mechanism keeps track of the movement position of the head carriage assembly
and detects any operational a b normality. U nder initial settings, this is performed by detecting
the sensing plate at the back of the head carriage assembly.

The home position sensor is made up of an LED and photo IC, and movement of the head
carriage assembly causes the sensor plate to pass between the LED and photo IC. This cuts the
optic axis, which causes a change in the output level of the photo IC. The output level change is
read as a head carriage assembly movement position sensor signal.

Carriage sensor mechanism

The carriage sensor mechanism detects carriage motor operation abnormalities using the
carriage motor gear and a rotary encoder. This mechanism consists of a carriage sensor gear
installed ab ove the carriage motor gear train and a carriage sensor.

The carriag e sensor consists of an LED a nd photo IC. Drive power is transmitted from the
carriage motor to t he carr ia ge motor g e ar , t he ri bbon ad vanc e i nter mediat e g e ar, and then to the
carriage sensor gear, which is equipped with six equally spaced light blocking fins. Rotation of
the carriage sensor gear by the p ower transmitted from the carria ge motor causes th e fins to pass
between the LED and photo IC. This cuts the optic axis, which causes a change in the output
level of the photo IC. The output level change is read as a carriage motor rotation sensor signal.

B.O.F. sensor mechanism

The B.O.F. sensor mechanism detects whether or not paper is present or not when slip paper is
inserted into the printer, and it also detects the end of the paper during printing. It is located
near the right side of the paper set position so it can accurately check whether or not paper is
present in the printer.

The B.O.F. sensor consists of an LED and phototransistor. Inserting slip paper into the printer
cuts the optic axis between the LED and phototransistor, which causes a change in the output
level of the phototransistor. The output level change is read as a slip paper detect sensor signal.

The T.O.F. sensor mechanism detects whether or not paper is present or not when slip paper is
inserted into the printer. It is located near th e top of the pape r set position (before the form
stopper) so it can accurately check whether or not paper is present in the printer.

The T.O.F. sensor consists of an LED and phototransistor. The presence of paper is determined
based upon light reflection, and modulation is performed in order to eliminate the effects of
ambient light. The LED is swit ched on and off by applicatio n of a 2KHz p ulse, so phototra nsistor
output is extracted using a 2KHz filter in order to eliminate the effects of ambient light.

Cover open sensor mechanism

The cover open sensor mechanism uses a light blocking plate installed on the printer cover and
cover open sensor to detect whether the printer cover is open or closed.

Rev. A Mechanisms and Operation 2-9

Confidential

The printer cover open sensor co nsists of an LED and phototransisto r. When the pr int er cov er is
closed (black arrow in Figure 2.4.12), the cover open sensor plate (light blocking plate) installed
on the front cover’s frame is p ositioned between the L ED and phototr ansistor. This cu ts the optic
axis, which causes a change in the outp ut lev el of t he photot ransisto r. The ou tput level change is
read as a printer cover status sensor signal.

Immediately after detection of a printer open cond ition, the head carria ge assembly moves to the
far right side of its stroke and enters the wait state.

Paper feed mechanism wait state

The form stopper bar, which is located pe rpendicul ar to the sl ip paper pa th, is mainta ined by the
form stopper spring in a position that blocks the paper path (Figure 2.4.15). The platen frame
assembly is kept pressed down by the platen open and shut shaft. The platen open and shut
shaft is attached to the platen open and shut slider, which is linked to the ferrite core of the
platen open and shut solenoid (Figure 2.4.15).

The permanent magnet built into the platen open and shut solenoid maintains it in a pulled
state, while the platen frame is kept in contact with the platen op en and shut shaft by the platen
frame spring (Figure 2.4.15).

The head carriage assembly waits on the far left of the carriage stroke, and the wait state is
maintained until the slip paper top of f orm operation is complete .

Slip paper top of form operation

When slip paper is inserted along the right edge of the document table (case component) in the
direction of the white arrow in Figure 2.4.15, it enters up to the form stopper and then
positioning is performed. After the presence of paper is detected by both the B.O.F. and T.O.F.
sensors, release current is applied to t he platen open and shu t solenoid, releasi ng the ferrite co re,
which causes the platen open and shut slider to move in the direction of arrow (a). At the same
time, the movement of the platen open and shut shaft linked to the platen open and shut slider
rotates the platen frame assembly in the direction of arrow (b), so the paper feed roller applies
pressure against the paper holding roller, sandwiching the slip paper between them. While this
is happening, the platen open and shut shaft presses down the form stopper in the direction of
arrow (c), moving the form stopper out of the paper path to prepare for paper feed (Figure

2.4.15).

Next, the paper feed motor rotates counterclockwise (forward paper feed) viewed from the
paper feed motor gear side, or clockwise (reverse paper feed). The number of steps fed is in
accordance with the slip paper format. The resulting rotary force is transmitted to the transfer
gear, deceleration gear, middle gear, and on to the paper feed roller sub-assembly, and the slip
paper top of form operation is performed (Figure 2.4.16).

Paper feed oper ation

Following the slip paper top of form operation, the printer enters the printing mode. After one
line is printed, the paper feed motor operates to rotate the slip feed roller and feed the paper a
prescribed amount.

Though slip paper forward feed and reverse feed can be selected by controlling electrical signal
applied to the paper feed motor, basic operation generally calls for forward feed during the
printing operation and reverse feed to eject the slip paper.

2-12 Mechanisms and Operation Rev. A

Confidential

TM-H5000II Series Technical Manual

The paper feed mechanism’s gear train consists of a paper feed motor gear, a transmission gear,
a deceleration gear, a paper feed roller sub-assembly paper feed roller gear, and a paper hold
roller assembly paper hold roller gear (Figure 2.4.17). The output of the paper feed motor is
simultaneously transmitted to the paper feed rol ler and pa per hol d roller throug h the gea r train,
so paper feed force is generated on both sides of the slip paper.

During forward feed, the gears rotate in the directions of arrows (a), (b), (c), and (d), so the paper
feed roller rotates in the direction of arrow (e) and the paper hold roller rotates in the direction
of arrow (f), feeding the slip paper in the direction of the white arrow.

The directions of all the arrows are reversed during the reverse feed operation.

Immediately after the paper ej ect oper ation i s finished , attra ction curr ent is applied to the p laten
open and shut solenoid, which releases the pressure between the paper feed roller and paper
hold roller, and the pape r feed mechan ism returns to the wait state.

Ribbon Feed Mechanism

This mechanism consists of a ribbon feed transmission gear located on the right side of the

the drive force of the carriage motor to advance the ribbon.

Ribbon feed operation

When carriage motor operat ion cau ses th e carriag e motor gear t o rota te in the directio n of arr ow
(a) in Figure 2.4.19, the force is transmitted to the ribbon feed transmission gear and planetary
gear train. Planetary gears (1) and (2 ) shift as they are rot ated in the direction of arr ow (b) by the
small gear on the hub of the ribbon feed transmission gear. This shift causes the ribbon feed
planet lever to rotate in the direction of arrow (c) until planet gear (2) meshes with planet gear
(3). Since planet gear (3) is constantly meshed with the ribbon feed gear, the ribbon feed gear
rotates in the direction of arrow (d).

When carriage motor gear rotation is in the direction of arrow (e), the ribbon feed transmission
gear rotates in the direction of black arrow (f), and the planet gears (1) and (2) shift as they rotate
in the direction of arrow (g).

Along with this shift, the ribbon feed planet ge ar lever rotat es in the directio n of arrow (h) until
planetary gear 1 meshes with the ribbon feed gear, causing the ribbon feed gear to rotate in the
direction of arrow (d).

This operation causes the ribbon feed gear to rotate in the direction of arrow (d), regardless of

MICR Reader Mechanism (Factory Option)

The major components that make up the MICR reader mechanism are an MICR frame, an MICR
head set, and MICR solenoid, and MICR lever, and an MICR roller, all of which are integrated
into a single unit. This mechanism can be installed in the paper path of the paper feed
mechanism (where the MICR character s on checks p ass) as a facto ry option. Feed ing of the check
paper is performed by the paper feed mechanism.

MICR reader mechanism wait state

A permanent magnet built into the MICR solenoid inside the MICR unit maintains the solenoid
in a pulled state, and the MICR r oll er, whose axle runs through the MI CR rol le r, which i s l ink ed
to the ferrite core of the solenoid, is separated from the MICR head assembly. The gap between
the MICR head assembly and MICR roller is the paper path (Figure 2.4.20). This wait state is
maintained at all times except when an MICR read operation is being performed.

MICR read and endorsement print ing operation

Inserting check paper into the printer is performed the same way as slip paper insertion. When
check paper is inserted along the right edge of the document table (case component), it enters up
to the form stopper where positioning is performed. After the presence of paper is detected by
both the B.O.F. and T.O.F. sensors, the top of form operation described for the paper feed
mechanism is performed and then the printer prepares to feed the check paper (Figure 2.4.21).

Next, the paper feed motor rotates at the same speed of slip paper feeding and feeds the check
paper forward (in the direction of the white arrow) with a prescribed number of steps.

Rev. A Mechanisms and Operation 2-15

Confidential

Next, release current is applied to the MICR sol enoid, releas ing the ferrite core, whi ch causes the
MICR lever linked to the ferrite core to be rotated by the spring force of the MICR lever spring.
The MICR roller, whose supporting axis runs through the MICR lever, presses down on the
check paper against the MICR head assembly (Figure 2.4.21) arrow (a) direction).

Next, the paper feed motor reverse feeds the check paper a prescribed number of steps at the
MICR read speed and performs MICR reading.

After reading is complete, attraction current is applied to the MICR solenoid, rotating the MICR
lever and releasing the MICR roller pressure (Figure 2.4.21 arrow (b) direction). After the check
paper is forward fed to the endorsement printing position with a prescribed number of steps,
the validity of the check i s checked. If the MICR charac ters were not re cognized, t he check p aper
is forward fed without endorsement printing. In this case, repeat the read operation.

Once the check is judged to be valid, endorsement printing is performed according to a
prescribed format. After endorsement printing, the check paper is reverse fed and ejected from
the printer, and the operation is ended.

The paper feed required by this mechanism during the check paper MICR read and
endorsement printing series is performed by the standard slip paper feed mechanism. The only
difference is the operation speed during MICR reading.

M-T88II Printer Mechanism

This printer consists of six mechanisms: a paper feed mechanism, a paper supply mechanism, a
printer mechanism, a cutter mechanism, a cover mechanism, and a display mechanism. The
following illustration shows the external configuration of the M-T88II.

Figure 2.5.1 M-T88II external configuration

Paper Feed Mechanism

Paper feed is per f ormed by a power transfer mechanism that rotates the platen , a nd a head
holding mechanism that presses the thermal head against the platen.

Power transfer mechanism

On the frame cover, the platen is supported by the platen shaft holder so it turns freely. Closing
the frame cover causes the platen gear affixed to the platen shaft to mesh with the deceleration
gear equipped on the main frame. The rotary force (in the direction of arrow (1)) of the receipt
paper feed motor affixed to the main frame is transferred in sequence to the motor gear (press fit
to the motor shaft), the deceleration gear, and the platen gear, which rotates the platen in the
direction of arrow (2).

A PM type stepping motor is used for the receipt paper motor.

A separate type gear train is used for this mechanism. When the motor rotates in reverse, the
pressure angle relationship causes power to w ork in the dire ction that the gear train is
separated, so rev erse motor operation is impossible.

The pressure being applied to the platen by the thermal head acts as downward force on the
frame cover, and the platen is fixed in the positioning slot in the main frame. At this time, the
slots that support the thermal head bearings open i n the di rect ion of the back of t he head, so the
thermal head can move along the platen applying constant pressure along the print line.

Paper feed oper ation

Opening the frame cover, installing roll paper, and re-closing the frame cover causes the roll
paper to be sandwiched between the thermal head and pla ten. When the platen is rotated by the
power of the motor, friction generated between the platen and the paper feeds the roll paper in

environmental temperature, power supply voltage and DIP SW settings. The stepping motor
has a 2-2 phase drive for a speed over 70 mm/sec, and 1-2 phase drive for a speed of 70 mm/sec
or less. This maintains torque while suppressing motor heat and acoustic noise generation.

The paper outlet of the printer is covered, an d even if paper output becomes blocked for some
reason, there is enough room in the space between the platen and frame cover for accumulation
of two or three normal length receipts (the length of one sheet is assumed to be 80mm or less).
This reduces the chance of receip t paper becoming be nt and of t he print p itch becomin g uneven.

Near end sensor mechanism

The near end (N.E.) sensor lever is supported by the N.E. sensor holder so it can move. The
spring force of the microswitch fixed by a screw to the N. E. sensor holder p resses the N.E. sensor
lever in the direction of arrow (1) in Figure 2.5.9. The microswitch is linked to the switch circuit
board assembly-B by the N.E. sensor lead wire. The N.E. sensor holder is attached to the paper
guide by the sensor adjustment screw.

When the paper roll is larger than the prescribed roll paper diameter, the pressure of the outer
surface of the paper roll on the N.E. sensor lever causes the lever to press the microswitch,
maintaining it in an ON state.

When the remaining paper on the roll is below the prescribed diameter, contact between the tip
of the N.E. sensor lever and the paper roll surface is broken, causing the lever to move in the
direction of arrow (1), into th e core of the paper roll. This causes the micros witch to turn off,
indicating near end of the roll paper.

The prescribed near end roll paper amount can be changed between two different levels: one
with the N.E. sensor tab fixed in a raised position, and one with the N.E. sensor tab fixed in a
lowered posi tion.

passes the sensor, the volume of light from the LED that makes it to the phototra nsistor changes.
Because the reflectance ratios of the paper and the rubber platen surface are different, a change
in the output level of the phototransistor is detected as the end of the paper.

The shield plate provided around the sensor is grounded to the main frame. This printer is

Printer Mechanism

The thermal head is designed so its heating element is positioned where it comes into contact
with the platen. The roll paper wrapped around the platen is kept in contact with the thermal
head’s heating element at a prescribed pressure, and printing is performed when heat is
generated by the heating element.

This printer employs a thick-film t hermal head that consists of a head ti p with a heating ele ment,
a driver IC for driver control of the heating element, a ther mistor that monitors the temperature
of the thermal head, a heat shiel d that protects the head ti p agai nst abnormal hea t, a pr int ci rcuit
board that is link ed to the signal line, and head suppor t shafts (spring pin s ).

The thermal head is connected to the inter mit circuit board assembly-A located at the back of the
slip printer by an FFC connected to the connector. Figure 2.5.12 shows a cross section of the
thermal head heating unit and the (thermal) roll paper.

Printing is performed according to the following steps:

1. The print signal sends a prescribed energizing pulse to the electrodes that correspond to
each dot to be printed.

2. Resistors at each electrode generate heat.

reduced by the paper cutter motor gear and the drive gear, and then rotates a drive pin that is
press fit to the drive gear.

A microswitch is fixed to the paper cutter cover in order to sense the position of the stationary

1. Application of voltage between paper cutter motor terminals causes the motor to rotate
clockwise.

2. The drive pin moves the movable blade towards the stationary blade.

3. The movable blade and stationary blade intersect to cut the paper from right to left.

4. An uncut portion is retained on the left and the movable blade returns.

5. The microswitch detects when the movable blade returns to the home position, motor
operation is stopped, and movable blade operation is stopped.

Cutter blade knob

The movable blade is in the home positi on whenever c utter o perati on is not bein g performed . In
addition to safety considerations, this enables a mechanism in which the frame cover cannot be
opened or closed while the movable blade is not in the home position.

TM-H5000II Series Technical Manual

When the stationary blade is not in the home position during normal use, the paper cutte r motor
rotates in reverse to move the stati onary bl ade to the home positi on. The cutter motor gear has a
knob that makes it possible to move the movable blade when the drive force of the motor is
unable to return the stationary blade to the home position.

A window is provided in the paper cutter cover in order to make it possible to check whether
the movable blade has returned to the home position.

Cover Mechanism

A roll paper cover is fixed to the frame cover. The roll paper cover ensures the strength of the
cover section. The frame cover passes through the cover shaft, allowing the roll paper cover to
hinge on the main frame. A cover spring affixed to the main frame comes into contact with the
shaft on the frame cover, providing optimum load when the frame cover is opened and closed.

Cover open sensor mechanism

A transmissive type photosensor, consisting of an LED and phototransistor, is mounted on the
cover open board, and affixed to the main frame. The frame cover is shaped so it fits into the
photosensor, and closing of the frame cover causes the cover to enter into the photosensor slit,
cutting the optic axis. When the frame cover is raised, on the other hand, photosensor light
passes through the slit. This makes it possible to detect whether or not the cover is open by
monitoring the output level of the photo transistor.

Cover open button me ch anism

The cover open lever is supported by the main frame sha ft. The co ver open but ton al ong wit h its
return spring is supported by the side of the paper guide. Pressing the cover open button while
the frame cover is closed causes part of the cover open button to link with the cover open lever,
which rotates the cover open lever. The cover open lever pushes up the shutter blade, which
pushes up the frame cover. The platen pushes up the thermal head, separating them. This
removes the force stopping the frame cover, making it possible to open the frame cover with
little power. When the operator releases the cover open button, the cover open button is
returned to its prescribed position by the return spring.

The cover can also be opened by directly pulling up on the thermal cover AA (plastic cover)
with strong force.

Reset circuit

The reset circuit protects against runaway CPU processing during unstable voltages
immediately after power up, abnormal printing, and other unforeseen operation. Output of the
OUT pin (PIN 6) of the reset IC (Us) is supplied to the CPU (U4) as a RESET input signa l (PIN

30). The reset ICC (U2) monitors +5V voltage, and release the CPU reset when voltage rises
above 4.5V, which enable printer operat io n. The r eset I C (U2) C termina l (PI N 5) is con nected to
the reset signal (DSR signal or P IN 25 inp ut signa l) from t he host i nter face, v i a DI P swi tch 2-7 or
2-8. Reset sign als can be supplied power to cause reset IC outpu t to become low, which resets
the CPU.

Reset from the host interface differs in accordance with interface specifi cati ons, as shown be low.

Selection between two signals (DSR signal or PIN 25 input signal) is possible.

1284 parallel interface spe cifications

Always use the #25 RESET signal. DIP switch 2-8 is always on. With the 1284 parallel interface,
this printer can be reset from the host interface signal’s nInit signal (PIN 3 1).

M-U590 Control Circuits

Impact head drive circuit

The slip printer mechanism’s impact printer head consists of nine pins, each of which is driven
by a solenoid. Energizing signals (SHEAD1 to SHE AD 9) are out pu t to each print head solenoid
from the gate array (U5) ports (HEAD 1 to HEAD 9), and a solenoid common control signal
(SHDCOM) is output from HDCOM. Current flows to the solenoids when signals SHEAD 1
through 9 turn on sink transistors QM2, QM3, and Q22, and SHDCOM signal turns on source
transistor Q17. When the source transistor is off, the energy stored in the solenoids flows
through flywheel diodes D11 and D12. When the sink transistor is OFF, current flowing to the
solenoids is cut off.

Head temperature is detected by inputting thermistor voltage and R92 split voltage (signal THS)
to the analog port of the CPU, via the analog switch IC (U17).

The platen open-close solenoid and MICR solenoid (factory option) is constant-current driven
by a special-purpose IC. Since the circuit is configured for common use of both solenoids, the
following explanation covers the platen open-close solenoid drive circuit only. The special­purpose IC switches the energizing direction from the gate array (U5) to the solenoids, and
signals SPL_1 and SPL_2 are applied. The special-purpose IC switches the energizing current to
the solenoids in accordance with these signals, and performs opening and closing of the platen.

Paper feed motor drive circuit

The paper feed motor has a precise angle of rotation (highly precise movement amount), and
allows control of motor speed. When pin PE4 of the gate array (U5) goes low, +24V are applied
to the COM terminal of the paper feed motor co il, and SPF_A, SP F_B, SPF_ A, and SPF_B change
between H and L. The H/L change speed of SPF_A, SPF_B, SPF_A, and SPF_B determines the
speed of the motor. Pin PE4 of the gate array (U5) changes back to H after the paper feed
operation is complete.

Detector circuits

Slip TOF sensor circuit

The slip TOF sensor circuit is a reflective type photosensor, so a 2KHz frequency modulation
system is employed to eliminate the effects of ambient light. The STOF_K signal (emit) is added
to the signal which turns on or off on 2kHz from the CPU (U4). The STOF (pickup) signal passes
through the filter circuit and amplifier circuit. These signals are read by the CPU (U4) from the
analog port to determine whether or not paper is present.

Rev. A Mechanisms and Operation 2-39

Slip BOF sensor circuit

The slip BOF sensor becomes enabled when the PTLED_COM2 signal output from the gate
array (U5) is on. BOF sensor signal SBOF is input to the CPU analog port via the analog switch
IC (U17).

Cover open sensor

The cover open sensor is l ocated next to th e slip printer mechani sm. Detect or sig nal S_COVER i s

Home position sensor, carriage positi on sensor

These sensors are located inside the slip printer mechanism. Home position sensor signal
SHP_DT is input to the gate array (U5) and carriage position sensor signal SCR_DE is input to
the CPU (U4), both via the CR integrating circuit.

MICR signal detection/analo g signal switching circuit

MICR head read signal MIRD is input to the CPU analog port via the analog switch IC (U17).

MICR reader operating principles

MICR stands for “magnetic ink character recognition.” Unlike conventional printing ink,
magnetic ink includes iron powder or some other magnetic element, which give the ink itself
magnetic properties.

Application of a magnetic field on one side of characters printed with magnetic ink on a check
cause the characters to become magnetized as shown in the illustration below. Though this
example uses a bar magnetic, actual reading of magnetic i nk char act ers i s performed by pa ssing
current through a coil in the read head, creating an electromagnetic field.

The print head of the receipt printer mechanism is a thermal type print head with 512 dots per
line. All print head control is performed by a gate array. A driver is built into the print head, and
sending of print signal RSI, which is synchronized with the RSCKL signal, to the driver sets the
print/non-print status of each dot. Data is confi rmed by latch signal RLT. Pr int time control is
performed by RSTB1 and RSTB2, while energizing time is controlled by the gate array.

Changes in head temperature causes fluctuation of the resistance value of the thermistor built
into the head, which is output as temperature signal THR via the analog switch IC (U17). This
signal is read by the analog port of the CPU (U4).

Paper feed motor drive circuit

The paper feed motor is constant-current driven by a special-purpose IC. The energizing
direction switching signals (RPF_PH1 and RPF_PH2) from the CPU and the constant-current
switching signals (RPF_01, RPF_11, RPF_I02 and RPF_12) are supplied to the special-purpose
IC. The special-purpose IC controls t he pa per feed mot or i n acco rd ance wi th t hese sig nals u sing
OUT1A, OUT1B, OUT2A, and OUT2B signals.

Detector circuits

Paper end sensor circuit

The thermal printer mechanism is equipped with a paper end sensor, which is connected via
switch circuit board assembly-B and the intermit circuit board assembly-A to the main circuit
board unit-A. The paper end sensor is enabled when the PTLED_COM signal output from the
CPU (U4) is on, and paper end signal RRE is input to the CPU’s analog port via the analog
switch IC (U17).

Cover open sensor circuit

The cover open sensor is located next to the thermal printer mechanism, and it is connected via
switch circuit board assembly-B and the intermit circuit board assembly-A to the main circuit
board unit-A. Detector signal R_COVER is input to the gate array (U5).

Near end sensor circuit

The near end sensor is located next to the thermal printer mechanism and the roll paper holder.
It is connected via switch circuit board assembly-B and the i ntermit circuit board assembly-A to
the main circuit board unit-A. Detector signal RNE is input to the gate array (U5).

DIP Switch Read Circuit

There are a total of 14 DIP switches in banks DSW1 (switches 1 to 8) and DSW2 (switches 1 to 6).
Low level is read when a switch is ON and high level is read when a switch is off.

Malfunction Protection Circuit

The malfunction protection circuit protects against continuous energizing of the printer
mechanism due to runaway processing by the CP U, etc. T he foll owi ng ar e the causes to activate
the malfunction protection circuit:

❏ Output of the WDTOUT
❏ Output of SW24V_1 and SW24V_2 signals from the gate array (U5) due to runaway

processing by the CPU.

❏ TIMI signal output when a bnormal continu ous output t o paper feed motor drive circuit (slip

side only) and driver is detected.

❏ TIMI signal output when print head (both slip and receipt) temperature is abnormally high.

When any of the above triggers occur s, power supp ly to the recei pt pr inter mecha nism is tur ned

Customer Display Interface Circuit

Note

The customer display can be connected only when the host computer is equipped with an RS-232
interface.

This printer has a DM interface for connection of a customer display (DM). The driver/receiver
IC (U1) converts the RS-232 and customer display interface signal (TTL <--> 12V).

In configuration (b), the DM’s pass-through function is employed to allow printing on the this
printer (TM).

In configuration (c), in order to make is possible to send data to DM via TM, the host interface
connector’s RXD signal (PIN3) is also connected to the RXD signal pin (PIN3) of customer
display interface connector CN3.

Connection of the EPSON customer display is selected when DIP switch 2-2 is ON. When this
printer is inst alled, the DTR si gnal from the cu stomer display a nd the logical product signal o f

Drawer Kick Control Circuit

Signals DKD1 and DKD2 from gate array (U5) g oing active cause transistors Q7 and Q6 to turn
on, which in turn turns on transistor array QM1, outputting the drawer drive signal. The DK_S
signal, which indicates whether or not the drawer is open, is input to the gate array (U5), and
this status can be obtained from the host interface. The drawer power supply of +24V is suppl ied
via the regulator IC (U8), and the power supply is cut whenever over current or over duty
occurs.

Filter Circuit

A +24C DC (24 ±10%) power supply is input from connector CN1 after passing through the
filter circuit. The filter circuit reduces external noise and protects against noise that is generated
internally from escaping through the +24V DC power supply.

+24V Control Circuit

The +24V power supply that from the filter is split between the printer power supply and +5V
(regulator circuit).

M-U590 Power Supply

The +24V power supply is supplied di rect ly to the pri n t er mechani sm. The outpu t cond it io ns of
drive circuits of the impact head, paper feed motor, carriage motor, and platen open-close
solenoid/MICR solenoid printer mechanisms are controlled by the SW24V_1 signal, which is
output from the gate array (U5). SW24V_1 is the +24V circuit protection signal. If abnormal
voltage is detected, if the CPU detects an error, if the system resets, or if a CPU abnormality is
detected, the power signal at the sta ge before th e drive circui t is t urned off, and sup ply o f power
to the printer mechanism is stopped.

M-T88II Power Supply

The power supply is supplied through a FET (Q5). The FET (Q5) controls the output condition
(+24V output on/off) in accordance with signal SW24V_2, which is output from the gate array
(U5). The signal SW24V_2 is a circuit protection signal for the +24V system.

Rev. A Mechanisms and Operation 2-45

Confidential

If abnormal voltage is detected, if the CPU detects an error, or if a CPU abnormality is detected,
the FET automatically turns off and +24V outp ut is stopped. +24V output is OF F during system
reset and if +24V is not being used by the printer mechanism.

+5V Control Circuit

A +5 regulator circuit switches the input +24V power supply and converts it to +5V. The
switching regulator IC (U9) switches the input +24V, C50 and L3 perform smoothing, and +5V
voltage is output.

The RS-232 power supply is generated by a charge up circuit built into the RS-232 interface’s
onboard driver.

Operational Precautions

Observing the following operational precautions protects the unit against damage.

CAUTIONS:

General

❏ The bottom frame of the unit is equipped with a grounding screw. Be sure to use this screw

to ground the u nit before using it.

❏ Connect the interface cable, power cable, and drawer cable to the applicable connectors of

the unit. Do not use undue force when plugging cables into connectors.

❏ Do not turn u nit power off during normal operation. Be especially careful to avoid turning

power off while a paper cut operation is being performed. Doing so can result in the cutter
blade being ex posed, which will make it impossible to open th e roll paper cover.

Receipt mechanism

❏ Never pull out receipt paper while the receipt roll paper cover is open.
❏ During normal operation, never open the cutter cover and rotate the cutter manual knob by

hand. Doing so can cause the cutter blade to be exposed, making it impossible to open the
roll paper cover.

❏ The heating element of the printer mechanism’s thermal head and the driver IC are easily

damaged. Never allow these components to come into contact with metal or other hard
objects.

❏ Never touch the printer mechanism’s (thermal head’s) heating element with your hand.

Doing so can soil the heating element and affect proper operation.

❏ The head and motor areas are ver y hot du ri ng and immediat ely after pr int ing . Do n ot t ouch

components in these areas directly with your hand.

Slip mechanism

❏ Always instal l a ribbon cassett e and load pape r before printin g.

●

If the paper runs out, be sure to load new paper before you resume printing.

●

If you try to print when there is no paper or no ribbon cassette in the printer, the print
quality of subsequent print jobs may suffer (the printing color may become uneven,
some dots may not be printed, or the paper may tear) because of damage to the surface
of the platen, printing wires, or ribbon.

❏ Since the areas around the print head and motor surface become very hot during and just

after printing, do not touch them directly with your fingers.
