2.1.1 Printer Mechanism
The Printer Mechanism for the Stylus CX1500/ME100 is newly designed. But, the
basic component of the Printer Mechanism is almost the same as the previous printer
(Stylus C41/C42/C43/C44/C45/C46).
This printer consists of Print Head, Carriage Mechanism, Paper Loading Mechanism,
Paper Feeding Mechanism, Ink System.
Like the previous printers (Stylus C41/C42/C43/C44/C45/C46), the Stylus CX1500/
ME100 is equipped with two stepping motors; one for the Paper Loading/Feeding
Mechanism and the Pump Mechanism with the CR Lock Mechanism, and one for the
CR Mechanism. The ASF Unit for the Paper Loading Mechanism uses rear entry front
eject system. And, single LD Roller in Holder Shaft Unit loads a paper to the Printer
Mechanism.

2.1.2 Print Head
The Print Head is the same U-CHIPS type as the previous printer (Stylus C41/C42/
C43/C44/C45/C46), and makes it possible to perform multiple shot printing and
variable dot printing.
The Print Head nozzle configuration is as follows.
V Nozzle layout
Black : 48 nozzles x 1 row (nozzle pitch of row: 1/120 inch)
Color : 45 nozzles x 1 row (nozzle pitch of row: 1/120 inch)
The nozzle layout when viewed from the back surface of the Print Head is shown below.

The Print Head has the Electric Poles (CSIC Connectors) to store the ink consumption
amount data into the CSIC chip mounted on the Ink Cartridge. By storing the ink
consumption amount data, this printer can detect the ink consumption status, such as
Ink Low/Out condition.
The basic operating principles of the Print Head, which plays a major role in printing,
are the same as the previous printer (Stylus C41/C42/C43/C44/C45/C46); on-demand
method which uses PZT (Piezo Electric Element). In order to uniform the ejected ink
amount, the Print Head has its own Head ID (6-digits code for this Print Head for
Stylus CX1500/ME100) which adjusts PZT voltage drive features.
So, you are required to store the Head ID pasted on the Print Head into the EEPROM
by using the Adjustment program when replacing the Print Head, the Main Board Un it,
the Printer Mechanism with new one. (Note: there are no resistor arrays to determine
the Head ID on the Main Board.) And then, based on the stored Head ID into the
EEPROM, the Main Board generates appropriate PZT drive voltage.
Figure 2-2. Nozzle layout
OPERATING PRINCIPLES Overview 31
Page 32
EPSON Stylus CX1500/ME100 Revision A
Following explains the basic components for the Print Head.
V PZT
PZT is an abbreviation of Piezo Electric Element. Based on the drive waveform
generated on the Main Board, the PZT selected by the nozzle selector IC on the
Print Head pushes the top of the ink cavity, which has ink stored, to eject the ink
from each nozzle on the nozzle plate.
V Electric Poles for CSIC
This Electric Poles connects the CSIC chip mounted on the Ink Cartridge. By
using this poles, current ink consumption amount data is red out from the CSIC
chip. And, the latest ink consumption amount data is written into the CSIC chip.
V Nozzle Plate
The plate with nozzle holes on the Print Head surface is called Nozzle Plate.
V Filter
When the Ink Cartridge is installed, if any dirt or dust around the cartridge needle
is absorbed into the Print Head, there is a great possibility of causing nozzle clog
and disturbance of ink flow, and alignment failure and dot missing finally. To
prevent this problem, a filter is set under the cartridge needle.
V Ink Cavity
The ink absorbed from the Ink Cartridge goes through the filter and then is stored
temporarily in this tank called “ink cavity” until PZT is driven.

2.1.2.1 Printing Process
This section explains the process which the Printheads of On-Demand inkjet printers
eject ink from each nozzle.
1. Normal state:
When the printing signal is not output from the Main Board (C572 Main), or the
PZT drive voltage is not applied, the PZT does not change the shape. Therefore,
the PZT does not push the ink cavity. The ink pressure inside the ink cavity is kept
normal.(refer to Figure 2-4 (p.33): Normal state)
2. Ejecting state:
When the print signal is output from Main board (C572 Main), the nozzle selector
IC located on the Print Head latches the data once by 1-byte unit. Based on the
drive waveform (common voltage) generated on the Main Board, the PZT selected
by the nozzle selector IC pushes the top of the ink cavity. B y this operation, the in k
stored in the ink cavity is ejected from nozzles. (refer to Figure 2-4 (p.33):
Ejecting state)
Ink path PZT Ink cavity
Normal state
2.1.2.2 Printing Method
For printing dot system, the Stylus CX1500/ME100 has the following two kinds of
printing mode.
T Multiple shot printing
T Variable dot printing
The above two printing modes are automatically selected depending on the media and
the resolution setting of the printer driver. The following explains each printing mode.
V Multiple shot printing
This printing mode is developed to improve the print quality on plain paper or
transparencies in low resolution. The multiple shot printing mo de uses n ormal do t,
and the number of dot shot varies from 1 shot to maximum 3 shots depending on
the print data to enable to output sharp image even in a low resolution.
V Variable dot printing
This printing mode is developed to improve the print quality on exclusive paper.
This mode is basically the same as variable dot printing mode used on other
products; micro dot, middle dot and la rge dot compose this mode. The pri nting dot
size varies according to the print data and this mode enab les to output even sharper
image on exclusive paper.

The drive of the CR Motor is transmitted to the Carriage Unit via the Timing Belt.
And, the CR Home Position is detected with the HP/PE Sensor. This sensor is available
as the CR Home Position Sensor while the CR Motor operates in each sequence. (The
function of this sensor varies depending on the running condition of the motors. It is
available as the PE Sensor when the PF Motor operates in each sequence.)
When the detection plate molded on the Carriage Unit pushes down the HP Detection
Lever and the CR home position is detected with HP/PE Sensor, HIGH signal is output
to the CPU.

error”. And also, in case that the Carriage Unit cannot move outside the home position
and the CR home position is not detected with the HP/PE Sensor, the printer indicates
the “Paper jam error”.

through gears for the Paper loading/feedin g mechanism. The Paper loading mechanism
plays a role in loading a paper from the ASF Unit to the PF Roller. And also, the Paper
feeding mechanism plays a role in feeding a paper loaded from the ASF Unit. The
functions of the Paper loading/feeding mechanism varies depending on the rotational
direction of the PF Motor as the table below.

For your reference, the top or the end of a paper is usually detected with the HP/PE
Sensor. In case that the HP/PE Sensor cannot detect the top of a paper in the paper
loading sequence, the printer indicates the “Paper out error”. If the HP/PE Sensor
cannot detect the end of a paper in the paper feeding sequence, the p rinter ind icates th e
“Paper jam error”. As for the details, refer to Chapter 3 “Troubleshooting”.
2.1.4.1 Paper Loading Mechanism (ASF Unit)
The Paper loading mechanism consists of the Change Lever in the Pump Unit, the
Holder Shaft Unit (including the Clutch mechanism) and the ASF Unit.
The Change Lever and the Clutch mechanism play a major role in the Paper loading
mechanism as follows.
1. ASF home position detection function
The ASF Unit on this printer does not have the ASF Home Position Sensor.
Instead of the ASF Home Position Sensor, the Change Lever and the Clutch
mechanism is used to detect the ASF home position.
When the Change Lever is set on the C lutch mechanism with the co unterclockwise
rotation of the PF Motor pinion gear, the ASF home position is detected by this
lever for the paper loading operation. In this time, the printer cannot load a paper
from ASF Unit because the drive of the PF Motor is not transmitted to the LD
Roller Shaft.
2. Paper loading function
When the Change Lever is released from the Clutch mechanism with the
clockwise rotation of the PF Motor pinion gear, the ASF home position detection
function is changed over to the paper loading function. Therefore, the printer can
load a paper from ASF Unit because the drive of the PF Motor is transmitted to LD
Roller Shaft.
On this printer, the Paper Return Plate is built in ASF Unit instead of the Paper Return
Lever. The LD Pad is stacked on the Paper Return Plate, and it works with the tension
force of the Torsion Spring 29.1 mounted on the ASF Frame.
When an arc portion of the LD Roller pushes down this plate into the ASF Frame
during the paper loading sequence, a paper is loaded from the ASF Unit. A cutout
portion of the LD Roller releases this lever and this plate returns papers to the stand-by
position for next paper loading operation.
Following figures (refer to Figure 2-8 (p.37)/Figure 2-9 (p.38)) show you the ASF
paper loading sequence and the operation of each mechanism.

Clutch Gear. As the result,
the LD Roller Shaft dose
not rotate at all because
the drive of the PF Motor
is not transmitted. In this
time, the ASF Hopper is
also pushed down by the
ASF hopper release lever
on the LD Roller Shaft,
and the Paper Return Plate
is set to avoid that papers

Unit for next pape r loading
operation.
Then, when the rolling LD
Roller & the Clutch come at
the above “Step 1” position,
the Clutch Lever is locked
with the Change Lever again.
In this time, the drive of the

2.1.4.2 Paper Feeding Mechanism
The Paper feeding mechanism consists of PF Motor, PF Roller, EJ Roller, Paper End
Sensor (HP/PE Sensor) etc. The Paper feeding mechanism feeds a paper loaded from
ASF Unit by using pairs of roll ers .
1. One pair is the PF Roller and the Paper Guide Roller which is assembled in the
Paper Guide Upper/Left. The drive of the PF Motor is transmitted to the Paper
Guide Roller through the PF Roller.
2. Another pair is the EJ Roller and the Star Wheel which is assembled on the Front
Frame. The drive of the PF Motor is transmitted to the Star Wheel through the EJ
roller.

2.1.5 Ink System Mechanism
The Ink system mechanism consists of Pump mechanism with Carriage lock
mechanism and Capping mechanism with Wiper mechanism. Following table lists the
function for each mechanism.

Note "*": Like the previous SPC (Stylus CX3500/CX3600/CX3650), this printer adopts the
valveless cap system. The air valve system used for the previous printer (Stylus
COLOR 740) have two functions by the CR position in the capping condition as
follows.
This is to cover the surface of the Print Head with the cap in
order to
This is to remove the foreign material and unnecessary ink on
the nozzle plate of the Print Head.
This is to eject the ink from the Ink Cartridge, the ink c avity and
the cap to the Waste Ink Pad.
This is to lock the Carriage Unit with the Change Lever while
the Carriage Unit is at the home position.
prevent the nozzle from increasing viscosity.
1) Valve closing condition (CL position)
By closing the air valve, the ink is forcibly absorbed from the ink cartridge
or the ink cavity by the Pump Unit and is ejected to the Waste Ink Pad while
the Carriage Unit is in the CL position.
2) Valve open ing cond ition (Ink absorption position)
By opening the Air valve, the negative pressure is decreased and only the
ink inside the Cap is ejected while the Carriage Unit is in the further right
side than the CL position. (the ink is not absorbed from the ink cartridge or
the ink cavity.)
The following shows you the Carriage Unit position for each condition easily.

But, on the valveless cap system, the above 2) operation is done outside the
capping position. The Carriage Unit moves outside the CR home position and
the pump absorbs the ink inside the Cap.

2.1.5.1 Capping Mechanism
The Capping mechanism covers the Print Head with the Cap to p revent the nozzle from
increasing viscosity when the printer is in stand-by state or when the printer is off.
When the Carriage Unit is in the
home position, the hook of the
Slider Lock Lever is not latched to
the dent of the Cap Frame.
In this time, the protrusion of the
Cap Slider does not reach the
rightmost position of the Cap
Frame.

2.1.5.2 Pump Unit Mechanism
The PF Motor also controls the Pump Unit mechanism (inclu ding the Change Lever ) as
well as the Paper loading/feeding mechanism. The drive of the PF Motor is always
transmitted to the Pump Unit. (And also, its drive is transmitted to the LD Roller
through the Clutch mechanism & the Change Lever.)
On this printer, the Pump Unit mechanism including the Change Lever plays a major
role expecting the ink eject operation. And, these operations control depending on the
PF Motor rotational direction as the following table below.

2. Carriage lock operation by the Change Lever
Unlike the previous printer (Stylus COLOR 680), this printer does not have the
Carriage Lock Lever with the Wiper.
Instead of the Carriage Lock Lever, the Change Lever is set to the front side of the
printer while the Carriage Unit is in the CR home position.
(As for the detailed mechanism for setting the Change Lever, refer to Figure 2-8
(p.37) Step 2)
2.1.6 Ink Sequence
V Initial ink charge
After the printer is purchased and the power is turned on for the first time, the
printer must perform the Initial Ink Charge to charge the ink inside the ink cavity.
When the Initial Ink Charge is completed properly, the printer releases the flag
inside the EEPROM. Initial Ink Charge will take about 90 seconds for Stylus
CX1500/ME100. If the power is turned off during the Initial Ink Charge, the CL1’
will be performed at next power on timing.
V Manual Cleaning
The Stylus CX1500/ME100 provides four types of manual cleaning to clean air
bubbles, clogged ink with viscosity or foreign substances.
The following manual CL can be performed by the control panel operation, the
printer driver utility and the Adjustment program.
T Wiping ope ration
Wipes the nozzle plate by the rubber part on the Cap Unit.
T Flashing ope ration
Prevents color from mixing, and stabilizes ink surface inside the nozzle.
Independently of the printing path after t he previous CL, perform manu al CL from
CL1 to CL2 in order if the cumulative printing timer counter is less than 10min.
Only when the cumulative printing timer counter is more than 10min, execute only
CL1.
Additionally, if the I/C is Ink Low or Out condition, any manual cleaning is
prohibited and it is di splayed on th e LED indica tors.

Timer Cleaning
Like the previous SPC (Stylus CX3500/CX3600/CX3650), this printer dose not
have Timer IC and Lithium battery which is used for the backup power source for
Timer IC. So, this printer manages the printer off period or cleaning cycle by using
the following method.
The Printer Driver sends the timer command to the printer before printing. The
timer command is generated based on the PC’s timer and it consists of year, month
date, hour, minute and second. As soon as the printer receives the timer command
from the Printer Driver, the printer stores its command in the EEPROM. Then, it is
compared with the latest CL time which is stored in the EEPROM. And, in case
that the timer cleaning period is over the specific period, the printer performs the
timer cleaning automatically. In this time, the printer stores the timer command in
the EEPROM.
V Flashing
Two different flushing operations are executed for the following reasons.
T Pre-printing flushing
This is done before a start of printing to eliminate ink viscosity in the Print
Head nozzles.
T Periodic flushing
This is done during printing to prevent ink viscosity in the Print Head nozzles
from increasing.

2.2 Scanner Mechanism
The Scanner Mechanism of Stylus CX1500/ME100 is constructed of a Scanner
Carriage Unit, Scanner Motor, etc., in the same way as previous A4 size scanners.
2.2.1 Scanner Carriage Mechanism
2.2.1.1 Scanner Carriage Unit Overview
The Scanner Carriage Unit is constructed of a CIS Board (including linear CCD), Rod
Lens Array, LED (light source), etc.
V CIS Board
This takes the light information read from the document by the Rod Lens Array
and converts it to digital information using the linear CCD.
V Rod Lens Array
Many rod-shaped lenses are arranged in parallel, and the upright multiple images
of each lens is overlapped to form a single continuous image. Compared to a
regular lens, this has the special ability to reduce the distances between images.
It can project at 1 to 1 size for imaging a linear CCD with a width identical to an
A4 size document.
V LED
The unit uses an LED for an exposure light source. Using an LED eliminates the
need for an inverter board, and power consumption is reduced.

2.2.1.2 Scanner Carriage Unit Movement Overview
Scanning image is performed in the main scan direction (=1 line) by the CCD sensor
and in the sub-scan direction (=several lines) combined with Scanner Carriage Unit
movement. (refer to the figure below)
Line type, color CCD sensor can scan 1 line in main scan direction (parallel to the
Scanner Carriage Unit) by one time. When scanning next lines after the second line in
sub-scan direction, CR driving moves the Scanner Carriage Unit, which has CCD
sensor inside, and scan the other lines. The scanned data is sent to the control board.
The scanned data for “n” lines and “n-1” line are processed consecutively.

The Scanner Motor uses a stepping motor and drives using open loop control.
This scanner has no sensor mounted to detect the home position, which is a difference
from previous A-4 size scanners. When pattern label data fastened to the rear side of
Scanner Housing Upper is read, the Scanner Carriage Unit is determined to be in the
home positi on. (Refer to Figure 2-14 (p.45)/Figure 2-15 (p.45))

4.2 Caution regarding assembling/disassembling
of the Printer Mechanism, and how to ensure
of quality on re-assembled product
On current low end models, we basically forbade to remove Housing Lower (Inner)
from Printer mechanism in your repair. This is because there is a possibility of main
frame deformation when a part (such as Ink system) is removed from Printer
mechanism without Housing Lower (Inn er).
Therefore, if you want to replace Ink system/PF motor, we recommend to replace with
new Printer mechanism with Housing Lower (Inner).
Therefore, we clarify caution regarding assembling/disassembling of the printer
mechanism without Housing Lower (Inner), and how to ensure of quality on repaired
production this section.
[Caution regarding assembling/disassembling of the printer mechanism]
1) Main Frame
(a) Control of assembled standard pos i t ion.
[Reason]
• The assembled accuracy of each part composed of Printer mechanism is
based on Housing Lower (Inner).
[Service treatment]
• Confirm that there is no gap between main frame and Housing Lower
(Inner).
[Reference]
• To ensure the assembled accuracy, you have to control the assembled
standard position of main frame against X/Y/Z-axis direction.
[X-axis direction]
• Make sure that main frame is correctly placed on the groove of Housing
Lower (Inner).
• Make sure that there is no gap between main frame and Housing Lower
(Inner).
[Y-axis direction]
• Make sure that cut-out portion of main frame is correctly placed on the
square protrusion of Housing Lower (Inner).
[Z-axis direction]
• Make sure that there is no gap between main frame and Housing Lower
(Inner).
• Make sure that the left side of Printer mechanism is correctly fixed by one
hook.
(b) Control of vertical level of guide rail (Guide rail means the portion latched by
hooks of Holder IC & Print Head assy.)
[Reason]
• There is a possibility that printing failure/operation failure occurs by guide
rail deformation.
[Service treatment]
• Hold up the specified position of main frame to avoid the deformation.
(c) How to assemble of ASF Unit/Main Board/Paper Guide Upper
[Reason]
• There is a possibility that main frame deformation is caused extra force in
assembling. As the result, printing failure/operation failure occurs.
[Service treatment]
• Hold the opposite side by hand while you are installing the above parts.
2) Front Frame
(a) Control of vertical level
[Reason]
• There is a possibility that printing failure occurs by Front Frame
deformation.
[Service treatment]
• Handle Front Frame in assembling/disassembling carefully.
3) Holder IC
(a) Handling of Holder IC
[Reason]
• If Holder IC is damaged in assembling/disassembling of your repair, there is
a possibility that vital problem occur in user’s further operation.
[Service treatment]
• Released two hooks of Holder IC from the inside of Holder IC by tweezer.
[How to ensure of quality on re-assembled product]
We judge that the quality of re-assembled product is ensured if there is no problem
about the print result by adjustment program.
