Power Safety Precautions

Warning

Power Source

Disconnecting Power

For 115 VAC printers, do not apply more than 127 volts RMS between the
supply conductors or between either supply conductor and ground. For 230
VAC printers, do not apply more than 254 volts RMS between the supply
conductors or between either supply conductor and ground. Use only the
specified power cord and connector. This manual assumes that the reader is
a qualified service technician.

Plug the three-wire power cord (with grounding prong) into a grounded AC
outlet only. If necessary, contact a licensed electrician to install a properly
grounded outlet. If the product loses its ground connection, contact with
conductive parts may cause an electrical shock. A protective ground
connection by way of the grounding conductor in the power cord is essential
for safe operation.

Turning the power Off using the power switch does not completely de­energize the printer. You must also disconnect the power cord from the
printer’s Alternating Current (AC) inlet. Disconnect the power cord by pulling
the plug, not the cord.

Disconnect the power cord in the following cases:

■ if the power cord or plug is frayed or otherwise damaged,

■ if any liquid or foreign material is spilled into the product,

■ if the printer is exposed to any excess moisture,

■ if the printer is dropped or damaged,

■ if you suspect that the product needs servicing or repair,

■ whenever you clean the product.

Electrostatic Discharge Precautions

Some semiconductor components, and the respective sub-assemblies that
contain them, are vulnerable to damage by Electrostatic Discharge (ESD).
These components include Integrated Circuits (ICs), Large-Scale Integrated
circuits (LSIs), field-effect transistors, and other semiconductor chip
components. The following techniques will reduce the occurrence of
component damage caused by static electricity.

Be sure the power is Off to the chassis or circuit board, and observe all other
safety precautions.

■ Immediately before handling any semiconductor components assemblies,

drain the electrostatic charge from your body. This can be accomplished
by touching an earth ground source or by wearing a wrist strap device
connected to an earth ground source. Wearing a wrist strap will also
prevent accumulation of additional bodily static charges. Be sure to
remove the wrist strap before applying power to the unit under test to
avoid potential shock.

■ After removing a static sensitive assembly from its anti-static bag, place it

on a grounded conductive surface. If the anti-static bag is conductive, you
may ground the bag and use it as a conductive surface.

■ Do not use freon-propelled chemicals. These can generate electrical

charges sufficient to damage some devices.

■ Do not remove a replacement component or electrical sub-assembly from

its protective package until you are ready to install it.

■ Immediately before removing the protective material from the leads of a

replacement device, touch the protective material to the chassis or circuit
assembly into which the device will be installed.

■ Minimize body motions when handling unpacked replacement devices.

Motion such as your clothes brushing together, or lifting a foot from a
carpeted floor can generate enough static electricity to damage an
electro-statically sensitive device.

■ Handle ICs and Erasable Programmable Read-Only Memories

(EPROMs) carefully to avoid bending pins.

■ Pay attention to the direction of parts when mounting or inserting them on

Printed Circuit Boards (PCBs).

General Information

Printer Introduction and Overview

The Xerox Phaser 3300MFP Multifunction Product combines print, copy,
scan, and fax functions in one unit. The print engine has a single-pass laser
design architecture, which offers print speed at 30-ppm, and resolution up to
1200 x 1200 dots-per-inch image quality. The printer supports PostScript 3
and PCL 6 for Base and Network configurations. Automatic 2-sided printing
and network capability are standard features of the Phaser 3300MFP unit.

The scanner uses a CCD for document scanning. Scanning is accomplished
either manually or with the automatic document feeder (ADF). The scanner
provides input for the copy, scan, and fax functions.

Theory of Operation

Phaser 3300MFP Operational Overview

The Phaser 3300MFP is a monochrome multi-function product that uses
Laser Scanner Unit (LSU) with an electrophotographic process in the print
engine, a moving CCD in the automatic feed scanner, and a built-in fax­modem for fax functionality. The printer system consists of one print cartridge
which creates toner image.

Summary

The Phaser 3300MFP is roughly made up of: Main Controller, Control Panel,
Scanner, Line Interface, and Power subsystems. Each subsystem is a
separate module that focuses on common and standard designs of different
kind products. The Main controller consists of 1 CPU and 1 Board. The
Scanner consists of the ADF and Platen, and is connected to the Main
Controller by a harness. The Line Interface Unit is designed to apply TBR21
standard (Domestic, Europe, etc.)

1. CPU: ARM920T, which is exclusive controller to execute Printer & FAX

Function and to execute operation block by flash memory within system
program, and to control whole system.

■ Main function block

■ Completely Integrated System for Embedded Applications

■ DMA — 6 Channels (if not use CIP4e, 4ch is available for external

DMA.
If CIP4E used (a4 DMA channel use), 2ch available for external DMA)

■ Operation Frequency: CPU Core -> over 300 MHz, System Bus ->

100 MHz

■ Operation Voltage: Core Voltage -> 1.2 V, I/O Pad Voltage -> 3.3 V,

RTC Voltage -> 3 V

Paper Empty Sensing

The operation of the Paper empty sensor actuator (Photo Interrupter) on the
HVPS reports to the CPU whether the tray is empty or not. When the tray is
empty, the CPU sends a Paper Empty message to the Control Panel display.

MPT Sensing

By operation of Actuator on the frame, MP Sensor (Photo interrupter) on the
HVPS reports to the CPU whether is present or not. If paper is present in the
MPT, it is fed into the machine.

Phaser 3300MFP Service Manual 2-3

Theory of Operation

Paper Feed Sensing

When paper passes the feed sensor actuator, the photo interrupter signals the
CPU, which releases the image data after certain time.

If the CPU doesn’t detect the feed sensor within 1sec. after paper is fed,
paper Jam0 occurs.

The fact whether the print cartridge is inserted or not is detected by CRUM.
After the print cartridge is mounted, the sub-CRUM can read the information
of print cartridge from contact with CRUM involved in print cartridge. If the
information of print cartridge is invalid, it will show invalid sign on a LCD.

Paper Exit Sensing

It detects paper state whether paper gets out from the set with operation of
exit sensor on the HVPS and actuator on the frame. Paper detects the on/off
time of exit sensor by reading D22 of CPU, and the normal operation or jam
information is informed to the CPU. The paper JAM2 is reported.

Cover Open Sensing

The Cover open sensor is located on the HVPS. After the front cover is
opened, +24VS (DC fan, Solenoid, Main Motor, Polygon motor part of LSU
and HVPS), which is supplied to the each unit, is cut off. The cover-open
sensing is operated by the D23 of CPU. In case, the red will be ON for
informing the facts to user.

DC FAN/SOLENOID Driving

The DC Fans are driven by transistor and controlled by D14 (FAN MAIN), E16
(FAN DUPLEX), C23 (PICK-UP CLUTCH), C18 (REGI CLUTCH), D15 (MPF
CLUTCH) of CPU. When it is high, the fan is driven by turning on the TR, and
it is off when the sleep mode is selected.

There are three solenoids, and they are driven by paper pick-up, regi and
MPF signal. It is turned on or off by C23, C18, D15 of CPU. The diode
protects the driving TR from the noise pulse generated when the solenoid is
de-energizing.

Motor Drive

The main motor driving circuits are on the BLDC Motor Assembly Unit. The
Main Controller has the interfacing circuits.

There is a motor driver IC on the motor control board of Motor Assembly Unit.
The exit motor driving circuits are formed when the driver IC is selected.

Safety Features

■ To prevent overheating

■ 1st protection device: H/W cuts off when detecting an overheating

■ 2st protection device: S/W cuts off when detecting overheating

■ 3st protection device: Thermostat cuts off power to the lamp

■ Safety device

■ Fuser power is cut-off when the front cover is open

■ LSU power is cut off when the front cover is open

■ The temperature of the fuser cover's surface is maintained at less

than 80ºC to protect the user and a caution label is attached where
the customer can see it easily when the rear cover assembly is
opened.

The LSU unit is controlled by the video controller. It scans the video data
received from video controller with laser beam by using the rotation principle
of the polygon mirror to create a latent image on the OPC drum. It is the core
part of LBP.

The OPC drum rotates as the same speed as the paper feeding speed. It
creates the /HSYNC signal and sends it to the engine when the laser beam of
the LSU reaches the end of the polygon mirror, and the engine detects the /
HSYNC signal to arrange the vertical line of the image on the paper. After
detecting the /HSYNC signal, the image data is sent to the LSU to arrange the
its margin on the paper.

Each facet of the polygon mirror scans a single line.

SMPS & HVPS board

The SMPS supplies DC Power to the System. It takes 110 V/220 V and
outputs the +5 V, +24 V to supply the power to the Control Board.

The HVPS board creates the high voltage of THV/MHV/Supply/Dev and
supplies it to the print cartridge for making best condition to display the image.
The HVPS takes the 24 V and outputs the high voltage for THV/MHV/BIAS,
and the high voltage output is supplied to the toner, OPC cartridge, and
transfer roller.

■ The (+) Transfer Voltage is not outputted because the THV PWM is

controlled with high.

■ The (-) Transfer Voltage is outputted because the THV-Enable Signal

is controlled with low.

■ The output fluctuation range is big because there is no Feedback

control.

2) SMPS (Switching Mode Power Supply)
It is the power source of entire system. It is assembled by an independent

module, so it is possible to use for common use. It is mounted at the side of
the set.

It consists of the SMPS part, which supplies the DC power for driving the
system, and the AC heater control part, which supplies the power to fuser.
SMPS has two output channels. Which are +5 V and +24 V.

Theory of Operation

Fuser AC Power Control

AC power to the Fuser is controlled with a Triac, a semiconductor switch. The
ON/OFF control is operated when the gate of the Triac is turned on/off by
Phototriac (insulating part).

When the ‘HEATER ON’ signal is turned on at engine, the LED of PC501
(Photo Triac) flashes. From the flashing light, the Triac (light receiving part)
takes the voltage, and the voltage is supplied to the gate of Triac and flows
into the Triac. As a result, the AC current flows in the lamp to create heat.

When the signal is off, the PC501 is off, the voltage is cut off at the gate of
Triac. The Triac is turned off, interrupting power to the lamp.

Control Algorithm

Theory of Operation

Feeding

If feeding from a cassette, the drive of the pickup roller is controlled by
controlling the solenoid. The on/off of the solenoid is controlled by controlling
the general output port or the external output port. While paper moves,
occurrence of Jam is judged as below.

ITEM Description

JAM 0 ■ After picking up, paper cannot be entered due to paper is not fed.

■ After picking up, paper entered but it cannot reach to the feed sensor in

certain time due to slip, etc.

■ After picking up, if the feed sensor is not on, re-pick up. After re-picking

up, if the feed sensor is not on after certain time, it is JAM 0.

*It is a status that the leading edge of the paper doesn't pass the feed
sensor.

Transfer

JAM 1 ■ After the leading edge of the paper passes the feed sensor, the trailing

edge of the paper cannot pass the feed sensor after a certain time. (The
feed sensor cannot be OFF)

■ After the leading edge of the paper passes the feed sensor, the paper

cannot reach the exit sensor after certain time. (The exit sensor cannot be

JAM 2 ■ After the trailing edge of the paper passes the feed sensor, the paper

cannot pass the exit sensor after certain time.

Dup

Dup
JAM 0

■ After the trailing edge of the paper passes the exit sensor, the paper

cannot pass the Dup sensor after certain time.

■ After the trailing edge of the paper passes the Dup sensor, the paper

cannot pass the feed sensor after certain time.

The charging voltage, developing voltage, and transfer voltage are controlled
by PWM (Pulse Width Modulation). Each output voltage is changeable due to
the PWM duty. The transfer voltage produced when the paper passes the
transfer roller is determined by environment recognition. The resistance value
of the transfer roller changes due to the surrounding environment of the set.
The voltage value, which also changes due to the environment, is changed
through AD converter.

Phaser 3300MFP Service Manual 2-33

Theory of Operation

Fusing

The temperature change of the heat roller’s surface varies with the resistance
value through the thermistor. The resistance value determines how much
voltage will be converted into heat to raise the temperature of the fuser. If the
value measured by the thermistor is out of controlling range, one of the errors
below may occur:

Error Temperature Control Concept

Open Heat Error 90 °C below for 45 sec at Warm up

Over Heat Error 230 °C over for 10 sec or 240 over for 5 sec

Low Heat Error Standby: 130 °C below for 10 sec

Printing: 35 °C below for 7 sec at consecutive 2 page printing.

Open Heat Error

This error occurs when a specified temperature is not reached during the
warm up process. When this happens, the engine stops all functions and
processes. The engine then informs the error status to the main system. An
error message is then displayed on the LCD which informs the user.

Recovery is performed automatically. Maximum heat is supplied to the fuser
and a second reading is taken. When the specified temperature is reached,
the printer resumes operation as normal.

Low Heat Error

This error occurs when the temperature is lower than the specified
temperature during stand-by, printing or warm-up mode. When this happens,
the engine stops all functions and processes. The engine then reports the
error status to the main system. An error message is then displayed on the
LCD which informs the user.

Recovery is performed automatically. Maximum heat is supplied to the fuser
and a second reading is taken. When the specified temperature is reached,
the printer resumes operation as normal.

Over Heat Error

This error occurs whenever the printer temperature is higher than specified.
When this happens, the engine stops all functions and processes. The engine
then informs the error status to the main system. An error message is then
displayed on the LCD or LED which informs the user.

Recovery is performed automatically. The heat supply is cut off to the fuser
and a second reading is taken. When the temperature is a degree below the
specified temperature, printer resumes operation as normal.

LSU

Theory of Operation

The LSU receives image data from PVC or HPVC and makes a latent image
on OPC surface. It uses the dual beam, LD1 and LD2. But the control method
of each is the same.

Compared to the single beam, the dual beam has half of the LSU's frequency.

->The frequency of the dual beam = the frequency of the single beam /2.
The errors related to LSU are as follows:

By LReady: When the printing is started, the engine drives the polygon motor
of LSU. After the specified time is elapsed, if the motor is not in a ready status,
the engine detects the error that the polygon motor is not in a ready status. If
this error happens, the engine stops all functions and keeps it at the error
state. Also, the engine informs the error status of the main system and the
error message is displayed at LCD window to inform the error status of the
user.

By Hsync: When the polygon motor is ready, the LSU sends out the signal
called Hsync and used to synchronize with each image line. So, if the engine
does not detect consecutively the signal for a fixed time, it defines the Hsync
Error. If this error happens, the engine stops all functions and keeps it at the
error state. Also, the engine informs the error status of the main system and
then the error message is displayed at LCD window to inform the error status
of the user.

LSU Error Recovery: If the LReady or Hsync error happens, the paper exits out
beforehand. The engine mode is changed to recovery mode and the engine
informs the main system of the engine mode. And the engine checks the LSU
error. If the error doesn‘t happen, the printing job will be proceeding.

As shown in the block diagram, the Host Side is made up of:

■ Driver — a Windows software application that translates printed data to

one of the printer languages, and creates a spooler file.

■ Web-based Application — offers various printer additional functions:

management of printing jobs, printer administration, status monitor for
monitoring printer status in real time on the Web, independent
environment on OS.

■ Stand-alone Application — similar in functionality to Web-based

applications.

■ Port Monitor — manages the network communication between spooler

and Network Interface Card, or various additional applications and
Network Interface Card, (this is, at first, make communication logical port,
manage the data, transfer them from spooler to network port, and offer
the result of printing).

The Firmware Side is made up of:

■ Network Interface Card — relays communications between Host and

kernel using various network protocols

■ Kernel — manages the flow control of emulation procedure, receiving

data from Host or Network card and printing with engine & rendering job

■ Emulation — interprets the various output data from selected emulation

■ Engine — prints rendered bit-map data to paper with size and type

required by Kernel.

And then, for Job Spooling function for Multi-User, Multi-Printing that occurs in
Network printing and various additional printing functions, this Kernel use
max. 10 Queuing systems in a memory.

Phaser 3300MFP Service Manual 2-37

Theory of Operation

In Printing, the two procedures are

■ Using the USB Port

a. When the user starts to print the desired document to a PCL or PS

string, the Driver translates the all-graphic data and sends the data to
the host spooler. The spooler then sends the data stream to the
printer via the USB port.

b. The Kernel receives this data from Host, and then select emulation fit

to data and start selected one. After emulation job end, Kernel sends
the output bit-map data to Engine using Printer Video Controller (by
clock type for LSU).

c. Engine print the received data to required paper with the sequential

developing process.

■ Using the Network Interface Card

a. When the user starts to print the desired document to a PCL or PS

string, the Driver translates the all-graphic data and sends the data to
the host spooler.

b. The Port monitor managing the network port receives data from

spooler, and sends a data stream to the Network Interface Card.

c. The network interface card receives the data and sends it to the

Kernel.

d. The Kernel receives this data from Host, then selects an emulation

that fits the data, and start the selected emulation. After the emulation
job ends, the Kernel sends the output bit-map data to the Engine
using Printer Video Controller (by clock type for LSU).

e. The Engine prints the received data to the selected paper with the

sequential developing process.

The additional printing function are realized in

(1) Web environment.
(2) Window environment.
In addition, the Kernel reports printing status and printer status with the Status

Monitor.
