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 (ESD) 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
(EPROM’s) carefully to avoid bending pins.
■ Pay attention to the direction of parts when mounting or inserting them on
Printed Circuit Boards (PCB’s).

Controller Functions
Job Control
Cancel Print
Forced Output
IP Filter
User can cancel a print job while printing is in progress using the Cancel
button on the Control Panel. Job cancellation is not immediate. Depending on
the job size, it may take a while to completely cancel.
This function forces the printer to print the received data when the printer is
waiting for the remaining data during job processing.
User can accept or reject print jobs up to five specified IP addresses. IP filter
is available only to LPD and Port9100.
Job Recovery
When a print job fails due to a paper jam, the printer automatically restarts the
job after the jammed paper is removed. User does not have to reprint the
entire job.
Job Timeout
When job transmission is interrupted for a certain period of time, the print data
is deleted as an error. The timeout setting can be changed using the menu on
the printer’s Control Panel.
Print Volume Management
Print Volume (PV) Management manages print volume per user and can
manage up to 50 users.
RAM Disk
RAM Disk functions when memory is expanded, enabling Collation, Secure
Print, Proof Print, Form Overlay, and Font Download. 256 MB is needed to
enable RAM Disk and all related functions.
1-20 Phaser 6125/6130 Color Laser Printer Service Manual
General Information
Collation
The job is stored in the memory and multiple copies are printed. When the
entire job does not fit in the memory, the printer prints one copy up to the
stored pages, and the remaining are discarded.
An error message will appear on the Control Panel: “Error xxxx Press set
key.”
Two options are available to ensure Job Collation will process effectively:
■ Break large print job into multiple small print jobs
■ Increase memory for the printer
Secure Print
When memory is expanded to 256 MB or more, the printer holds print data,
including a User Password (11 digits), User Name, and Document Name in
the memory.
■ User ID – consists of a variable length from 1 to 24 byte characters (20H-
FFH). The driver requests the User ID from the user when the Secure
Print option is selected. A user ID cannot be blanked with only space
characters.
■ User Password – consists of a variable length from 0 to 11 digits. The
password is an optional input and hidden from the user interface by
displaying “*” for each digit. If a password is not specified, the driver will
accept it as a zero-length string so that a password will not be required
when requesting job output from the printer.
■ Document Name – consists of a variable length from 0 to 24 characters
(20H-FFH) that specifies the document name.
The data will not be printed until the same password, user name, and
document name are provided via the printer menu on the Control Panel. User
can remove or keep the data after printing the document. The data remains in
the printer memory as long as it is not cleared and will be cleared when the
printer is turned off. User can omit entering a password (this is called Store
Print - not available for MAC OS 10.2.).
Proof Print
Proof Print can be selected only when multiple sets of prints are specified in
the printer driver. Proof Print requires at least 256 MB of memory. The printer
prints only the first set of the print data including a user name and document
name specified in the printer driver. User can keep or remove the data using
the printer menu on the Control Panel. The data remains in the printer
memory as long as it is not cleared and will be cleared when the printer is
turned Off. This function is not available for MAC OS 10.2 and Linux operating
systems.
Form Overlay
The function for writing PCL6 forms are downloaded into RAM Disk.
Phaser 6125/6130 Color Laser Printer Service Manual 21
General Information
Note
Font Download
PCL6 fonts can be downloaded into RAM Disk.
Billing Meters
The Billing Print counter provides the number of pages printed properly
(simplex print is counted as 1 and duplex print is counted as 2 - including N
up).
If an error has occurred after the one side printed properly during duplex
printing, it is counted as 1.
Same data is stored in two or more addresses in one IC. When the
Controller is replaced, IC can be transferred.
Counter Description
Color Print Counter Counts the number of pages printed in color (7 digits).
Mono Print Counter Counts the number of pages printed in mono (7 digits).
ID Print
Non-Genuine Mode
Total Print Counter Count the total number of pages printed in color and
mono (7 digits).
User can position and print the User Name on the upper right, upper left,
lower right, and lower left (only for PCL6) of the page.
When the Toner Cartridge life has ended, the printer stops accepting print
request (life of the Toner Cartridge is counted by the counter in the CRUM).
This mode can be changed so the printer will not stop at the end of the Toner
Cartridge rated life; however, the printer will display an end of life message on
the Control Panel.

Phaser 6125/6130 Operational Overview
The Phaser 6125/6130 Color Laser Printer is a full-color laser printer that
uses Raster Output Scanner (ROS) lasers with an electrophotographic fourcolor CMYK process. The tandem system consists of four color drums (C, M,
Y, and K) which creates the toner image.
The following block diagram provides the sequence of events for the
xerographic process (dashed lines) and the paper flow (solid lines) into and
out of the printer.

Charging
The Drum surface is charged with negative electricity by discharging of the
Bias Charge Roller (BCR) while rotating at a constant speed. This process is
performed in parallel for Cyan, Magenta, Yellow, and Black colors.
The BCR is kept in contact with the Drum and rotates following the rotations of
the Drum. The BCR is a conductive roller, which receives negative voltage
from the High-Voltage Power Supply (HVPS) and discharges a negative
Direct Current (DC) voltage.
The Drum surface is uniformly and negatively charged with DC bias voltage.
The Drum surface is a photoreceptor (which is an insulator in a dark area and
a conductor when receiving light) and the Drum inside is composed of
conductor.
The Cleaning Roller is a sponge that contacts the BCR to catch the toner.

Theory of Operation
Four laser diodes (one for each color) in the Laser Unit emit laser beams. The
beams are directed by mirrors to the rotating polygon mirror attached to the
scanner motor. As the polygon mirror rotates, the beams are directed through
a series of lenses and mirrors to each of the drums, which are scanned by the
beams from end to end in the axial direction.
Phaser 6125/6130 Color Laser Printer Service Manual 2-5
Theory of Operation
The negatively charged Drum surface is scanned by the laser beams to form
an invisible electrostatic latent image on the drum surface. The process is
performed in parallel for Cyan, Magenta, Yellow, and Black colors.
The area on the surface where the laser beam strikes becomes conductive.
The negative charge on the surface flows to the more positive drum, lowering
the voltage potential. In this way the surface areas exposed to the laser beam
become the electrostatic latent image.

Theory of Operation
Toner is electrically attached to the invisible electrostatic latent image on the
drum surface to form the visible toner image on the Drum.
The toner in the Toner Cartridge is agitated by the built-in Agitator and fed into
the Developer. The Augers are driven by the Toner Motor and the Developer
Motor in the Main Drive. The toner to be consumed according to the print
count is calculated and fed into the Developer. This process, called Toner
Dispensation, is controlled by two processes: Pixel Count Dispense Control
(PCDC) and Automatic Density Control (ADC).
The toner fed into the Developer and the carrier in the Developer are agitated
by the Auger, and supplied to the Magnet Roller arranged in the drum surface
area. The toner and carrier are charged by friction due to agitation (toner in
negative, carrier in positive), and they are attracted electrically. A uniform
layer is formed by the Trimmer Bar as the carrier magnetic substance is
attracted to the Magnetic Roller.
Phaser 6125/6130 Color Laser Printer Service Manual 2-7
Theory of Operation
The Magnet Roller is covered by a thin semi-conductive sleeve over the
surface. The Developer Bias voltage is supplied to this semiconductor sleeve
from the High-Voltage Power Supply (HVPS). Developer Bias is negative
Direct Current (DC) voltage combined with Alternating Current (AC) voltage.
The Magnet Roller is kept at constant negative voltage against the
photoreceptor layer of the drum by DC voltage. Therefore, at the area on the
drum surface where the negative electric charge does not decrease, potential
is lower than the Magnet Roller, while the potential is higher than the Magnet
Roller at the area where the negative charge on the drum surface decreases.
The AC voltage shakes the Developer on the Magnet Roller surface, causing
the toner to transfer to the drum.
Thus, the negatively charged toner is attracted only to the area on the drum
surface (electrostatic latent image) where the negative charge is lower than
the charge on the Magnet Roller, forming the toner image on the drum. Once
the toner adheres to the drum, the negative charge of the toner-bearing
location increases, which decreases the potential and the toner-attracting
force.

The toner image formed on the Drum surface is transferred onto the surface

and K.
Theory of Operation
■ Bias Transfer Roller (BTR) – The BTR is a conductive roller that
receives positive voltage from the HVPS. The BTR contacts the rear side
of the Belt and applies the positive voltage to the Belt.
■ Transfer Unit (Belt) – The Transfer Unit is a conductive unit that receives
positive voltage from the BTR. After the negative charged toner image on
the Drum surface is drawn by the positive charge on the belt, it is
transferred from the Drum to the paper. The Transfer Unit feeds the paper
toward the direction of the Fuser.
Phaser 6125/6130 Color Laser Printer Service Manual 2-9
Theory of Operation
Cleaning (Imaging Unit)
Excess toner is removed from the Drum and the BCR surfaces, while excess
charge is also eliminated from the drum surface.
■ Drum Cleaning – The cleaning blade contacts the surface of the drum
collecting the excess toner by scraping off toner.
■ Cleaning Roller – The Cleaning Roller contacts the surface of the BCR
collecting the excess toner by scraping off toner.
■ Charge Cleaning – When the Drum is charged by the BCR, any excess
charge hinders the Drum surface from being uniformly charged, which
may lead to print quality problems. The the latent charge pattern
remaining on the photoconductive drum is neutralized by the Erase Lamp
(LED) to prepare the drum for the next Exposure cycle.

Paper Tray
■ Left/Right Side Guide
The Side Guides move at a right angle to the paper transfer direction to
align the paper width.
■ Separator Roller
The Separator Roller and Feed Roller pinch the paper to prevent multiple
sheets of paper from feeding.
Phaser 6125/6130 Color Laser Printer Service Manual 2-15
Theory of Operation
■ Paper Tray End Guide
The End Guide moves in toward the paper transfer direction to determine
the paper size.
■ Bottom Plate
The bottom plate is locked to the tray bottom when the tray is pulled out of
the paper feeder, and unlocked when the tray is installed in the paper
feeder. When unlocked, the bottom plate lifts the paper, pushing it against
the feed roller using spring tension.
Multiple Sheet Feed Prevention
The sheets loaded into the Paper Tray are occasionally stuck together along
the edges, which can cause a multiple feed or a jam. The sheets are fed by
the Feed Roller to a position between the Feed Roller and the Separator
Roller. Normally, when only one sheet is fed, both the Feed Roller and
Separator Roller rotate to allow the sheet to pass.
However, when two sheets are fed concurrently, only the Feed Roller rotates.
The Separator Roller is locked, allowing the upper sheet to pass, separated
from the lower sheet that is stopped by the friction with the Separator Roller at
rest.
The Separator Roller is pushed toward the Feed Roller by spring pressure,
and controlled by the Friction Clutch with which it is coupled.

■ Manual Feed No Paper Sensor (Photo Sensor)
Detects presence/absence of paper in the Manual Feed Slot by the
change in actuator position.
Upon detecting the sheet, the Regi Roller rotates for a predetermined
duration to feed the sheet. The sheet is caught between the Rollers so
that it may not fall from the Manual Feed Slot.
The Rollers stop immediately when the Registration Sensor detects the
presence of paper.
■ Registration Sensor (Photo Sensor)
The Registration Sensor detects paper when the paper leading edge
reaches the Registration Chute. When paper is fed from the Manual Feed
Slot, the Registration Sensor measures the paper length. The On time of
the Registration Sensor is converted into the paper length.
On: The paper activates the Actuator.
Phaser 6125/6130 Color Laser Printer Service Manual 2-19
Theory of Operation
■ Registration Clutch
The Registration Clutch transmits drive energy from the Main Drive to the
Registration Rubber Roller, and transports paper from the Tray and
Manual Feed Slot toward the Imaging Unit. The timing of sheets feeding
from the Registration Assembly is adjusted by the duration of the
Registration Clutch operation so that the toner image on the drum can be
transferred to the appropriate position on the sheet.

Lead Edge Registration
When a sheet is fed from the Tray to the toner transfer position, the
registration of the sheet may not be correctly maintained due to misalignment
of lead edges in the tray.
To avoid this problem, the lead edge position needs to be aligned at the
Registration rollers before the sheet is fed in front of the Transfer Unit Belt, or
in front of the BTRs.
Theory of Operation
Registration Rollers
s6130-017
Before the Registration rollers are energized, the paper is advanced from the
tray to the rollers. This process aligns the leading edge as shown below.
By pushing the edge of the sheet against the Registration Roller that is not
turning, the lead edge of the sheet is registered.
Registration Rollers
Skewed Paper
Paper Size Control
The printer doesn’t have switches for detecting paper size, and the length of
paper is detected only by the Registration Sensor when feeding paper. If
printing data and paper size don’t match, an error is sent to the Image
Processor board.

Paper Detection
Since the paper path from Manual Feed Slot to the Registration Sensor is
different than from the Paper Tray to the Registration Sensor, the Registration
Sensor is provided with the Registration In Actuator and the Registration
Roller Actuator.
■ The Registration Roller Actuator detects the sheet from the Manual Feed
Slot and detects the tail edge of the paper from the paper tray.
■ The Registration In Actuator detects the lead edge of the paper from the
paper tray.
The movement of the Registration In Actuator does not affect the Registration
Roller Actuator.

The Laser Unit is an exposure unit that generates laser beams to form an
electrostatic latent image on the drum surface. The Laser Unit consists of the
following components: Laser Diode (LD) Board, Scanner Assembly, Start of
Scan (SOS) Board, Lenses, Mirrors, and Windows.
2-24 Phaser 6125/6130 Color Laser Printer Service Manual
Theory of Operation
■ Laser Diode Board
The Laser Diode Board consists of four laser diodes (LDs) corresponding
to C, M, Y, and K. Each LD converts the electric signals of incoming
image data into laser waves. In order to stabilize the laser light quantity
during formation of an electrostatic latent image, the LD Board monitors
the intensity of the laser beam to adjust it to the appropriate level. This
process is called Auto Power Control (APC).
■ Scanner
The Scanner consists of a Scanner Motor that rotates at a constant speed
and a Polygon Mirror that is mounted on the Motor Shaft. The laser light
output from the LD is directed onto the Polygon Mirror by the Mirror. The
Polygon Mirror, provided with six reflecting mirror faces, changes the
reflection angle of the laser light as it rotates, thereby allowing the laser
light to scan the drum along its axial direction. Scanning is performed
using one reflecting mirror face for each line.
■ Start of Scan (SOS) Board
The SOS Sensor on the SOS Board converts incoming laser beam, upon
detection, to an electric signal as reference for starting scanning, and
transmits this signal to the MCU Board. The SOS sensor signals are used
to synchronize the starting point of the laser beam scanning with the
starting point of the image writing.
■ Lenses
The laser light reflected from the Polygon Mirror reaches the drum
surface via the Lenses, Mirror, and Window. The Lenses correct
aberration.
■ Mirror
The Mirror directs the laser beam and secures an optical path.
■ Window
The window prevents debris from entering the Laser Unit.

Printer Control
Paper Size Detection
Laser Unit Light Quantity Control
The printer has no switches for detecting paper size; only the length of the
paper is detected by the Regi Sensor as the paper is feeding. If the detected
size does not match the size sent in the print data, an error is reported to the
Image Processor.
Image data is sent to the Laser Unit as an electric signal (data are expressed
with high and low voltage values), and the laser diodes convert the image
data from electric signals to optical signals (data are expressed with blinking
laser beams).
Variations in light quantity of laser beams or variations in the optical system
(such as lenses) or drum sensitivity cannot attain a proper electrostatic image.
Therefore, the laser beam light quantity is monitored and controlled by the
laser diodes.
The Laser Unit has four laser diodes for Yellow, Magenta, Cyan, and Black
respectively and the beam intensity is automatically adjusted for each color.
2-34 Phaser 6125/6130 Color Laser Printer Service Manual
Process Control
Potential Control
Theory of Operation
For stable printing, the parameters related to the image development must be
corrected as necessary. The process control is performed in two methods
after every 25 cumulative prints, upon termination of a print run, or during a
continuous run.
■ Potential Control
■ Toner Density Control
The following controls supplement the above controls:
■ High Area Coverage Mode
■ Admix Mode
To attain stable printing image density, the drum charging voltage, the
developing DC voltage, and the Laser Unit beam intensity are adjusted
according to the developing capability of each color carrier that varies
momentarily. The adjusted drum charging voltage, the developing DC voltage,
and the Laser Unit beam intensity are fed back to keep the printing image
density constant.
The outline of controls is as follows:
1. The Humidity/Temperature Sensor detects humidity and temperature.
2. The patches of respective colors (Yellow, Magenta, Cyan, and Black) for
the potential control are generated and transferred on the Transfer Belt.
3. The ADC Sensor (Density Sensor) detects the density of the patch on the
Belt.
4. The drum charging voltage, developing DC voltage, and the Laser Unit
beam intensity are adjusted for each color according to the detected
patch density.
Toner Density Control
Toner density must be kept constant to attain stable printing. The control
system for this purpose is called toner density control.
1. PCDC (Pixel Count Dispense Control)
The amount of toner to be consumed in the developing process is
calculated by counting the video signals entered to the Laser Unit. The
amount of the toner to be consumed is calculated by the toner dispensing
time. The toner motor is driven for the calculated toner dispensing time
when supplying the toner to the Developer.
2. ADC (Auto Density Control)
The patches of respective colors (Yellow, Magenta, Cyan, and Black) for
the toner density control are generated under a specified potential
condition, and transferred on the Belt. The ADC Sensor measures this
density, and the measured value is compared with reference value. If the
toner density is low, the toner dispense quantity is increased at the next
printing, or if the toner density is higher, the toner dispense quantity is
reduced at the next printing. The toner dispense quantity is calculated by
the toner dispense time. This calculation is made for each color.
Phaser 6125/6130 Color Laser Printer Service Manual 2-35
Theory of Operation
High Area Coverage Mode
A continuous printing of any image of area coverage exceeding the toner
dispense capability causes the toner density in the Developer to be lowered.
The High Area Coverage Mode postpones the next page feed and dispenses
extra toner during this time, if the toner dispense time reaches the specified
value during a continuous printing.
Admix Mode
The Admix Mode dispenses toner immediately to prevent the reduction of
toner density, whenever the value of the toner density control patch measured
by the ADC Sensor falls far below the standard value, by dispensing extra
toner. If the toner density level cannot be recovered after this operation, it is
determined that toner has run out.
ADC Sensor Control Function
The ADC Sensor is a reflection type sensor that radiates light from its LED
onto the target and detects the reflected light at its photoreceptor and outputs
electric signals responsive to the amount of the detected light.
To ensure an accurate patch density measurement, the surface of the ADC
sensor is cleaned to remove soil due to toner, etc., and the light amount
adjustment is made so that the reflected light amount satisfies the prescribed
value, when creating the patch for potential control and toner density control.
Color Registration Control
The printer uses a tandem electro-photographic system with Organic Photo
Conductor (OPC) Drums and direct transfer by the Transfer Belt. Because the
images are formed on the individual Drums of the respective colors and then
overlapped to form one image, a color shift may occur. The color registration
control calculates how much the registration is shifted, and adjusts the Laser
Unit write timing.
The scan control adjusts all four colors in the process direction.
The color registration control is made from a change in inside temperature
and the print count at the execution of the process control. This control is
outlined as follows:
1. With no toner on the Transfer Belt, the output value of the ADC Sensor is
measured to determine the threshold value.
2. The patches for color registration control are generated on the Belt.
These patches are composed of 10 mm lines of K, C, K, M, K, and Y in
this order by the amount of four dispense counts, led by a black trigger.

Fuser Temperature Control
After the target temperature is set, the Heat Roller surface temperature is
controlled by turning the Heater Lamp On/Off.
Temperature of individual area of the Heat Roller is detected by the Fuser
Non-Contact Sensor (NCS) in the middle of the Heat Roller and the Temp
Sensor at the edge of it.
The target temperature set up varies depending on the time of Warm-up,
Printing, or Process Control. The target set temperature is changed based on
the printer’s interior temperature detected by the Humidity Sensor.
Cool Down
As printing continues, the distribution of temperature in the Heat Roller
becomes uneven in both the paper feed and non-paper feed areas. Cooling
Down suspends paper feeling for a certain period of time so that the Heat
Roller temperature distribution can be uniform.
When the temperature of the Heat Roller edge is high, cooling down is
performed to lower the temperature to the target value.
Fuser NCS Sensor Warm-Up
The Fuser Non-Contact Sensor at the center of the Heat Roller loses its
accuracy when the temperature of the sensor itself is below -5° C. Therefore,
the sensor is warmed up when the temperature is below -5° C.

Introduction
Accessing Error History Report
This chapter describes error messages and numeric codes displayed on the
Control Panel or listed on the Error History page. These error indications
serve as the entry point into the troubleshooting process.
Troubleshooting of problems not directly indicated by or associated with an
error message or Chain Link code is covered in “General Troubleshooting” on
page 4-1. Print quality problems are covered in “Print-Quality
Troubleshooting” on page 5-1.
The printer tracks and reports errors in a number of ways. The two types of
error reporting discussed in this section include:
■ Error messages and Chain Link codes display on the Control Panel
■ Engine (fatal) and Jam Error logs display on the Control Panel or listed on
the Error History Report
Error History Report
1. From the Control Panel, press the Menu button.
2. Information Pgs is displayed. Press the OK button.
3. Press the Up or Down arrow button to find Error History. Press the OK
button.
4. The Error History Report is printed. When printing is finished, the menu is
displayed.
The Error History Report provides a list of error messages and Chain Link
codes relating to Jam errors and System (fatal) errors. The printer can retain
up to 42 Jam errors and 42 System Fail errors.
For Chain Link codes, Chain number (0 to 999) and Link number (0 to 999)
are assigned. Chain numbers are assigned for each component. The
component number that detects the Fault is entered in the Chain code, and
the Fault type is defined by the Link code.
Examples of Error message and Chain Link code:
■ System Fail History
■ Chain Link: 018-310
■ Paper Jam History
■ Paper Jam Type: IOT Remain Registration Jam
