To print a segment, two consecutive pulses are applied to the relevant nozzle (to print to consecutive dots). base head head-rank setting (short land) gap-rank indication circuit board thermistor Figure 2-4 Head (top view) head Chip cover head base head driver head IC (under cover head) Figure 2-5 Head (bottom view) Figure 2-6 Nozzle arrangement 2-4 Outline of Operation Rev.
Confidential TM-J8000/J8000P Technical Manual Data Input and Printing Figure 2-7 shows a block diagram of the driver IC. Each driver IC receives input through its DI (data) and XSCL.(sync) lines. These inputs are implemented separately on each of the two driver ICs (so that each receives data independently). The serial print data enters through the DI and moves into the SHIFT REGISTER in sync with the XSCL signal. The data then moves into the LATCH in accordance with the LP timing signal.
Confidential Figure 2-8 Head drive implementation Roll paper feed mechanism This mechanism comprises the paper-feed motor assembly, the power transmission mechanism, the roll paper cover unit, the roll paper guide unit, and the detector mechanisms. For explanations about the detector mechanisms (which includes the roll paper detection mechanism, the roll paper near-end detection mechanism, and the cover-open detection mechanism), see “Detector mechanism” in this chapter.
TM-J8000/J8000P Technical Manual Confidential Paper feeding The paper-feed motor assembly consists of a step motor and a gear ("Gear, paper feed motor"). The rotation of the motor propagates through three gears ("Gear, J/C changeover", "Gear, paper feed reduction", and "Gear, paper feed transmit") on the power-transmission mechanism, and causes the paper-feed roller assembly to rotate.
Confidential Paper loading The paper roll is loaded by putting it into the roll paper guide unit (which includes the paper supply section). The roll paper guide unit can be accessed by lifting the lock lever ("Lever, CS lock") and opening the cover ("Roll paper cover unit"). The operator puts the paper roll into place, pull out a small amount of the paper, and closes the cover. This causes the paper to set into the path illustrated in the figure below.
TM-J8000/J8000P Technical Manual Confidential J/S changeover mechanism This printer uses a single motor to feed both roll paper and slips. The J/S changeover mechanism switches the gear train so as to drive the correct paper. The mechanism consists of a gear ("Gear, J/S changeover"), solenoid ("Solenoid, J/S changeover"), and lever ("Lever, J/S changeover").
Confidential Slip paper-guide section This section consists of four major components: the front slip guide ("Paper guide, slip, front"), the upper slip guide ("Paper guide, slip, upper"), the lower slip guide ("Paper guide, slip, lower"), and the platen ("Paper guide, platen"). The paper path accepts slip paper up to a maximum width of 215.9mm. A slip holder guide ("Paper guide, slip hold, top") is attached at the top of the platen to guide the slip as it moves upward from the print area.
TM-J8000/J8000P Technical Manual Confidential When the J/S changeover mechanism is switched to the slip-feed mechanism side, the drive power from the paper feed motor ("Motor, paper feed") drives each gear on the drive side; all three of the slip-feed rollers rotate simultaneously.
Confidential Top-feed rollers The driven rollers ("Roller, slip hold, top") are supported by lever ("Lever, slip hold, top"). The solenoid ("Solenoid, slip hold, top") engaged at the tip of the lever causes the lever to open and close. The operation to absorb the solenoid’s iron core causes the rollers to open. The rollers will then stay open even after the solenoid power is shut off.
TM-J8000/J8000P Technical Manual Confidential Shutter mechanism Operating principle The purpose of this mechanism is to hold the entering slip firmly against the platen at the open area of the Platen where carriage passes through, so that the sheet is correctly guided up to the top slip-holder paper guide ("Paper guide, slip hold, top"). The shutter mechanism also controls the open/close action of the front-feed rollers and the form stopper.
Confidential lever, form stopper O/C lever, slip O/C lever, shutter drive gear, shutter reduct cam, form stopper O/C motor, shutter cam, slip O/C Figure 2-21 Shutter mechanism (3) The main components are: the shutter frame ("Frame, shutter"), the motor ("Motor, shutter"), the reduction gear ("Gear, shutter reduct"), the drive cam ("Cam, shutter drive"), the slider ("Slider shutter"), the drive lever ("Lever, shutter drive"), the shutter ("Shutter, slip"), the holder plate ("Holding plate, slip"), the
TM-J8000/J8000P Technical Manual Confidential The shutter detection mechanism can be used to detect abnormal shutter operation and to adjust the home position at time of shutter initialization. The user can control the shutter mechanism manually by turning the shutter reduction gear ("Gear, shutter reduction") at the point where it projects outward from the carriage frame.
Confidential Step 2 The shutter motor now turns in the CCW direction, returning the shutter mechanism to home position. The paper-feed motor then starts again, feeding the leading edge of the paper to the point where it is just about to reach the top slip holder guide ("Paper guide, slip hold, top"). Step 3 The shutter mechanism reaches the phase point indicated as T2 in the timing chart.

B.O.F. detector mechanism Detects presence of a slip. Slip detector mechanism Detects presence of a slip. Shutter detector mechanism Detects home position of shutter. Roll paper detector mechanism Detects presence of roll paper. Roll paper near-end detector mechanism Detects presence of roll paper.
Confidential The carriage detector consists of an LED and a photo IC. The circular detection plate, which looks like a wagon wheel, has 12 evenly spaced plate which blocks the light along the circumference of the detection plate, and there are open spaces in between. The detector plate is mounted directly on the rotating shaft of the carriage motor. Rotation of the carriage motor therefore causes the plate to turn as well.
TM-J8000/J8000P Technical Manual Confidential Pump position detector mechanism This mechanism detects the roller position. The mechanism consists of a pump-position detector plate (linked to a pressure pulley) and a pump-position detector. The pump-position detector consists of an LED and a photo IC. The detector plate, which includes a cutout area, fits between the LED and the photo IC and is turned by the power of the pump motor.
Confidential Cartridge detector mechanism The cartridge detector, mounted on the cartridge guide unit, detects whether the cartridge is installed, and whether it is installed correctly. Detection is by mechanical contact. The contact is closed if there is no ink cartridge in place. When the ink cartridge is installed correctly in place, the side of the cartridge presses against the actuator on the detector, causing the contact to open.
TM-J8000/J8000P Technical Manual Confidential Paper-width detector This detector detects the width of the inserted slip. The detector is mounted approximately 122mm from the right edge of the paper path. If the slip is wider than 122mm, the detector will detect its presence. In most cases checks are narrower than 122mm when fed vertically, but wider when fed horizontally.
Confidential The detector consists of an LED and a phototransistor. When a slip moves into place, light from the LED reflects from the slip back to the phototransistor. The phototransistor output changes accordingly, indicating that the sheet is in position. Figure 2-32 B.O.F. detection circuit Slip detector mechanism This mechanism is located just before the print position to confirm that the slip has advanced to the print position.
TM-J8000/J8000P Technical Manual Confidential Shutter detector mechanism This detector confirms that the shutter moves into home position (at initialization) and detects errors during the shutter operation. The detector mechanism is mounted around the circumference of the slip open/close cam ("Cam, slip O/C") inside the shutter frame ("Frame, shutter"). The detector mechanism consists of an LED and a photo IC, and works in conjunction with blocker areas on the cam.
Confidential A spring within the microswitch holds the lever so that it juts out into the paper path. When roll paper moves along the path, it presses the lever back out of the path, causing the microswitch contact to open. When paper runs out, the spring pulls the lever back into position, closing the contact on the microswitch.
TM-J8000/J8000P Technical Manual Confidential Cover-open detector mechanism This mechanism consists of lock lever ("Lever, CS lock") located on the roll paper cover, and a detection lever ("Lever, cover-open detect") and cover-open detector located on the gear-train frame assembly on the paper roll side. The mechanism detects the open/close state of the cover. The cover-open detector consists of an LED and a phototransistor.
Confidential The printer uses these signals to control stopping of the cutter motor and to detect errors related to the cutter mechanism. blocker plate cutter detector cutter carriage sub-assembly Figure 2-38 Cutter detector mechanism Autocutter mechanism The autocutter mechanism consists of a transmission mechanism, a detection mechanism, and a cutter mechanism. For information about the detection mechanism, refer to "Cutter detection mechanism" in this chapter.
TM-J8000/J8000P Technical Manual Confidential The rotation speed from the cutter motor passes from the cutter-motor gear through the reduction and transmit gears (which reduce the speed) to the drive pulley.

The cutter carriage sub-assembly then reaches home position on the side opposite from which it started, causing the detection mechanism to output a HIGH signal. The system responds by stopping the cutter motor, completing the sequence. Figure 2-41 Cutting operation Ink system mechanism The ink system mechanism consists of the following three mechanisms.
Confidential The following is a block diagram of the ink system. cleaner head clutch unit flat gear ink cartridge carriage unit cap unit ink pack pump motor ink discharging pump unit Figure 2-42 Ink system block diagram Pumping mechanism This mechanism comprises the pump motor and the pump unit. The mechanism sucks accumulating ink from the nozzles in the print head, and passes it through the cap section into the ink discharge absorber inside the ink cartridge. 2-30 Outline of Operation Rev.
TM-J8000/J8000P Technical Manual Confidential The pump consists of a roller, a tube, and a pressure pulley (see illustration below). To collect ink, the motor turns the pulley, causing the roller to press against and move around the tube. This action changes the internal capacity of the tube, creating a vacuum force pressure that sucks in the ink and ejects it into the ink cartridge. roller ink ejection pressure pulley ink absorption (Ink is not absorbed.
Confidential Wiping/carriage-lock mechanism The wiping mechanism wipes ink and dust off the surface of the nozzles, and is therefore a part of the head-cleaning process. Forward rotation of the pump motor acts on the pump gear, causing the clutch plate to move. The motion of the clutch causes the cleaner head to advance into the motion path of the print head.
