MLP is the abbreviation for Multi-Layer Piezoelectric element. When a drive pulse
(voltage) is applied, this element pushes the vibration plate, compressing the cavity
for ink injection from the nozzle.
Ink supplied from the ink cartridge is stored in this space and is injected from the
nozzles when the vibration plate compresses this area.
These inject ink against the paper’s surface in response to the application of the
print signal. There are 48 individual nozzles making up this printhead.

Operating Principles
This printer’s paper feed mechanism can feed paper either from the built-in ASF (auto sheet feeder)
or the manual feed slot. The paper feed drive motor is a 4-phase,
4t3-pole,
PM-type stepping motor
that directly drives the paper feed mechanism (paper advancing operation, paper pick-up
operation). This motor also drives the pump mechanism,
but only when the printer is in the
cleaning state.

The pump draws ink from the printhead nozzles and drains it into the waste ink drain tank. The
printer performs this operation to eliminate dust or bubbles within the nozzles. Figure 2-9
illustrates the pump operation. When the paper feed drive motor rotates CW (forward), the pulley
pumps in the wheel pump unit rotate in the direction of the arrow while squeezing the ink tube to
push the ink inside the tube out to the waste ink drain tank. On the other hand, when the motor

8) Moves the carriage to the standby position.
2.4.1.2 Cleaning Operation
This operation is performed when cleaning is selected by pressing the ALT and PAUSE buttons
simultaneously. There are three cleaning modes, each of which is selectively performed, depending
on the cleaning counter K value and the number of printed lines from the previous cleaning
operation.

The standby operation prevents an increase in the viscosity of the ink held inside the
printhead
nozzles. This operation is performed automatically if no data is received for more than three
seconds from the last print data.
1) Counts the number of flushing operations from the last standby operation, using the combined
print counter N. And performs the flushing based on the counter value.
2) Moves the carriage to the home position.

This operation is activated by the REFRESH-I signal, which outputs
every 20 seconds during continuous printing.
1) Returns the carriage to home position.
2) Moves the carnage to the flushing position.
3) Performs flushing operation.
4) Performs cleaner blade-III operation (including the flushing),
based on the value of the combined print counter N.
5) Performs false absorbing operation, if the ink level counter R
value exceeds 5600.
6) Returns to the previous state.
■
Print start
This operation ejects high-viscosity ink inside the nozzles when the
printing starts from the standby state.
1) Moves the carriage to the flushing position and performs flushing.
2) Starts printing operation.
■
False absorbing
This operation absorbs ink inside the cap and eliminates ink
attached to the nozzle plate surface.
1) Moves the carriage to the false absorbing position.
2) Performs false absorbing operation.
3) Resets the pump pulley.
4) Release a mechanical pressure of the pump drive mechanism.

2.4.1.6 Cleaner Blade Operation
The cleaner blade operation eliminates any dust or ink attached to the nozzle plate surface. This
operation consists of the following separate operational modes.
■
Cleaner blade - I
■
Cleaner blade -II
■
Cleaner blade - III
■
Rubbing
This operation eliminates any dust attached to the nozzle plate surface before
the ink absorbing operation is performed.
1) Sets the cleaner blade.
2) Moves the carriage to the cleaner start position.
3) Moves the carriage to the cleaner end position (head surface is wiped off
with the cleaner blade).
4) Resets the cleaner blade.
5) Returns the carriage to the home position.
This operation eliminates any dust or ink attached to the nozzle plate surface
after the ink absorbing operation is performed.
1) Sets the cleaner blade.
2) Moves the carriage to the cleaner start position.
3) Moves the carnage to the cleaner end position (head surface is wiped off
with the cleaner blade).
4) Resets the cleaner blade.
5) Moves the carnage to the flushing position and performs flushing.
6) Moves the carnage to the home position.
This operation removes any dust or ink attached to the nozzle plate surface
during printing.
1) Sets the cleaner blade.
2) Moves the carriage to the cleaner start position.
3) Moves the carriage to the cleaner end position (head surface is wiped off
with the cleaner blade).
4) Resets the cleaner blade.
5) Moves the carnage to the flushing position and performs flushing.
6) Moves the carriage to home position.
This operation removes dust or ink that adheres to the head surface.
1) Sets the cleaner blade.
2) Moves the carriage to the cleaner start position.
3) Moves the carriage to the cleaner end position
(wiping = rubber side)
4) Moves the carriage to the flashing position
(wiping = felt side).
5) Moves the carriage to the home position. (This resets the cleaner blade.)
2.4.1.7 UC Replacement Operation
This operation is performed when the ink cartridge (1/C) is replaced.
Moves the carriage to the I/C replacement position.
1)
Replace the ink cartridge.
2)

Operating Principles
2.4.1.8 Disengage ON Operation
STYLUS 800 Service Manual
This operation sets the switch lever to the position where it transmits the PF motor drive to the
pump mechanism.
1) Moves the carriage to the position D where the lever is set to the specified position.
2) Moves the carriage to the position B.
3) Release a mechanical pressure of the paper feed drive mechanism. (Generates a backlash.)
4) Moves the carriage to the false absorbing position.
5) Adjusts the gear phase with the pump drive mechanism gears.
6) Moves the carriage to home position.
2.4.1.9 Micro Absorbing Operation
A small amount of air possibly gets into the ink path as a form of tiny bubble when the
cartridge is removed from the carriage after once it is installed. Such a small air bubble blocks the
ink path to obstacle an ink injection from the nozzle. This operation eliminates small air bubble
from the cavity of the printhead.
1) Performs the false absorbing operation.
2) Performs the micro absorbing operation.

the flashing operation completes preceding a printing.
■
the refresh - I operation completes.
2.4.2.2 Flushing Counter
The flushing counter consists of the following counters.
■
Ink level counter R
I
Combined print counter N
2.4.2.3 CL Counter K
This counter indicates the amount of ink that exists in the cap, in
proportion to the number of flushing operations. When the counter
value exceeds or equals 5600 (R 2 5600), the printer performs the
false absorbing operation.
This counter is used to: 1) keep a wet condition inside the cap, 2)
perform the wiping operation regularly to remove dust or ink that is
attached to the head surface. The “operations activated by this
counter differ for 1) and 2) as follows:
1) The flushing operation is performed based on the counter N value
at the flushing position, when the printer is in the standby state.
2) Wiping is performed when counter N value is equal to an integral
multiple of 60.

4.1 OVERVIEW
This section describes procedures of the adjustment required when the printer is disassembled and
assembled after repair.
4.1.1 Precautions for Adjustment
You should refer to the precautions below when adjusting the printer.
Disconnect the power cable before when you attempt the adjustment. (Unless otherwise
specified.)
4.2
BI-DIRECTIC)NAL
The bidirectional printing alignment adjustment is required when the printer mechanism or the
main board is replaced. By performing this adjustment, a compensation value is determined for the
mechanical control as to compensate the deviation of print position, which may be caused by the
different print speeds due to the tolerance of the mechanical components, and the deviation of print
timing between odd-numbered lines and even-numbered lines in bidirectional printing. The
printer stores the compensation data in the EEPROM on the main board (C106 MAIN), and
referring to this data when the
