Power Safety Precautions
Power source
For 110 VAC printers, do not apply more than 140 volts RMS between the supply
conductors or between either supply conductor and ground. Use only the specified power
cord and connector. For 220 VAC printers, do not apply more than 264 volts RMS
between the supply conductors or between either supply conductor and ground. Use only
the specified power cord. This manual assumes that the reader is a qualified service
technician.
Warning: 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.
Disconnecting Power
Warning: Turning the power off using the On/Off switch does not
completely de-engergize the printer. You must also
disconnect the printer power cord from the AC outlet.
Position the power cord so that it is easily accessible during
servicing so that you may power down the printer during
an emergency.
Disconnect the power plug 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 case,
■ 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.
ivPhaser 6200 Color Laser Printer - Service Manual
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.
CautionBe 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 unpackaged 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 IC’s and 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).

Proof Jobs. A proof job is a specific case of a multiple-copy job. With a proof job, the
customer assigns a password and copy count at the client workstation before printing. The
first set of prints are printed immediately. The original number of requested sets are
printed after the customer enters the matching password on the printer’s control panel. The
customer has the option of printing the original number of requested sets or deleting the
job. Since more than one job may be associated with the same password, the customer can
print all the jobs, delete all the jobs, or select or delete individual jobs. A proof job that has
not been printed is retained on the optional internal hard drive through power cycles.
Secure Jobs. Secure printing allows the customer to defer printing of a job until a
matching password is entered from the control panel. The customer assigns the password
at the client workstation before printing. The job is stored, and printing is delayed until the
password is entered on the printer’s control panel. Since more than one job can have the
same password, all secure jobs with the same password are printed. A secure job that has
not been printed or released is retained on the internal hard drive through power cycles.
Saved Jobs. Saved print allows the user to save print jobs to the internal hard drive of
the printer. The print job is not deleted after printing, it is stored on the hard drive for print
on demand. This function requires an internal hard drive.
Printer Memory and RAM Capabilities
The printer features two slots which accept 64, 128 and 256 Mbyte of SDRAM. All
combinations are allowed for 64, 128, 192, 256, 320, 384 and 512 Mbytes.

Service Flowchart
The Service Flowchart outlines one possible approach to troubleshooting and repair
of the printer. The Service Flowchart is an overview of the path a service technician
could
take, using this technical manual, to service the print engine and options. If you
choose not to use the Service Flowchart, it is recommended that you start at the
appropriate troubleshooting table and proceed from there.
Always follow the safety measures detailed in the front of the manual when servicing
the printer. See "Service Safety Summary" on page vi of this manual.
Step 1: Identify the Problem:
1 Verify the reported problem does exist.
2 Check for any error codes and write them down.
3 Print normal customer prints and service test prints.
4 Make note of any print quality problems in the test prints.
5 Make note of any mechanical or electrical abnormalities present.
6 Make note of any unusual noise or smell coming from the printer.
7 Print a Usage Profile Report, if the printer is able to print.
8 View the fault history under the Service Tools Menu
9 Verify the AC input power supply is within proper specifications by measuring the
voltage at the electric outlet while the printer is running.
Step 2: Inspect and Clean the Printer:
1 Switch OFF printer power.
2 Disconnect the AC power cord from the wall outlet.
3 Verify the power cord is free from damage or short circuit and is connected properly.
4 Remove the Imaging Unit and protect it from light.
5 Inspect the printer interior and remove any foreign matter such as paper clips,
staples, pieces of paper, dust or loose toner.
■ Do not use solvents or chemical cleaners to clean the printer interior.
■ Do not use any type of oil or lubricant on printer parts.
■ Use only an approved toner vacuum.
6 Clean all rubber rollers with a lint-free cloth, dampened slightly with cold water and
mild detergent.
7 Inspect the interior of the printer for damaged wires, loose connections, toner
leakage, and damaged or obviously worn parts.
8 If a toner cartridge appears obviously damaged, replace with a new one.
Step 3: Find the Cause of the Problem:
1 Use the Error Messages and Codes and troubleshooting procedures to find the
cause of the problem.
2 Use Diagnostics to check printer and optional components.
3 Use the Wiring Diagrams and Plug/Jack Locator to locate test points.
4 Take voltage readings at various test points as instructed in the appropriate
troubleshooting procedure.
5 Use the “Engine Test Print”, page 96, to isolate problems with the Image Processor
Board.
Step 4: Correct the Problem
1 Use the Parts List to locate a part number
2 Use the Removal and Replacement Procedures to replace the part.
Step 5: Final Checkout
1 Test the printer to be sure you have corrected the initial problem and there are no
additional problems present.
20Phaser 6200 Color Laser Printer - Service Manual
Using the Troubleshooting Procedures
1. Each Step in a Troubleshooting Procedure instructs you to perform a certain action
or procedure. The steps are to be followed sequentially in the order given until the
problem is fixed or resolved.
2. The Actions and Questions box contains additional information and/or additional
procedures you must follow to isolate the problem.
3. When a procedure instructs you to test a component using service diagnostics, See
"Service Diagnostics" on page 23 for the detailed steps and functions for testing
parts of the printer.
4. The action is followed by a question. If your response to the question is “Ye s” ,
then follow the instructions for a “Ye s ” reply. If your response to the question is
“No”, then follow the instructions for a “No” reply.
5. Troubleshooting Procedures may ask you to take voltage readings or test for
continuity at certain test points within the printer. For detailed diagrams, refer to
the section "Plug/Jack Locator Maps" on page 341 and "Wiring Diagrams" on
page 351 for complete information on test point locations and signal names.
6. Troubleshooting Procedures often ask you to replace a printer component. The
section "FRU Disassembly - Removal and Replacement Procedures" on page 119
provides detailed steps for removing and replacing all major parts of the printer.
The section "FRU Parts List" on page 253 details the location, quantity and part
number for all spared parts of the printer.
General Notes on Troubleshooting
1. Unless indicated otherwise, the instruction “switch ON printer main power” means
for you to switch ON printer power and let the printer proceed through POST to a
‘Ready’ condition.
2. Conventions used to represent connectors
PlugJack
S6200-282
3. When instructed to take voltage, continuity or resistance readings on wiring
harness, proceed as follows; Check P/J 232–1 to P/J 210–5 by placing the red
probe (+) of your meter on pin 1 of P/J 232, and place the black probe (–) of your
meter on pin 5 of P/J 210.
4. When you are instructed to take resistance readings between “P/J 232 <=> P/J
210” (without specified pin numbers), check all pins. Refer to the the section
"Wiring Diagrams" on page 351 for the location of all wiring harnesses and pins.
5. When you are instructed to take a voltage reading, the black probe (–) is generally
connected to a pin that is either RTN (Return) or SG (Signal Ground). You can
substitute any RTN pin or test point in the printer, and you can use FG (frame
ground) in place of any SG pin or test point.
6. Before measuring voltages make sure the printer is switched ON, the Imaging Unit
and the paper trays are in place, and the interlock switches are actuated, unless a
troubleshooting procedure instructs otherwise.
Error Messages and Codes21
7. All voltage values given in the troubleshooting procedures are approximate
values. The main purpose of voltage readings is to determine whether or not a
component is receiving the correct voltage value from the power supply and if
gating (a voltage drop) occurs during component actuation. Gating signals may be
nothing more than a pulse, resulting in a momentary drop in voltage that may be
difficult or impossible to read on the average multi-meter.
8. When a troubleshooting procedure instructs you to replace a non-spared
component and that component is part of a parent assembly, you should replace
the entire parent assembly.
Voltage Measurements
Power and signal grounds are connected to the frame ground. All circuit
troubleshooting can be performed using the metal frame (chassis) as the grounding
point. To locate connectors or test points, refer to the section "Plug/Jack Locator
Maps" on page 341 or "Wiring Diagrams" on page 351 for more information.
Unless otherwise specified, the following voltage tolerances are used within this
section:
Voltage Measurements
StatedMeasured
+3.3 VDC+3.135 to +3.465 VDC
+5.0 VDC+4.75 to +5.25 VDC
+24.0 VDC+21.6 to +26.4 VDC

82Phaser 6200 Color Laser Printer - Service Manual
System Boot Sequence
1. When the main power switch is turned on, the health LED on the Image Processor
Board turns on immediately.
2. The boot loader checks for RAM present and functional. If not, it posts a very
large “RAM ERROR” on the front panel and blinks the LED 1/2 second on/off
continuously.
3. The boot Loader then runs POST diagnostics.
4. POST turns off the health LED.
5. Post checks the front panel.
6. If keys have been pushed, the front panel displays “Processing Input”.
7. The front panel LED cycles: Green, Yellow, Red, and then off.
8. The front panel turns on, the LED turns Green and the POST tests are run.
Power On Self Test (POST)
The following tests are performed when the printer is powered on, after the boot
loader runs, and before the operating system is loaded and initialized.
POST diagnostics are intended to provide a quick means of isolating a defective
subsystem associated with the Image Processor Board and SDRAM. POST returns
control to the boot loader and the operating system is loaded. The operating system
then loads the imaging processing software. If POST detected any soft errors, a
message is printed in a red box on the start page. If POST detects any hard errors,
both the front panel and health LED blink the error code pattern, see "LED Blink
Patterns" on page 84.
POST Startup indications
■ At power-on the hardware default is to turn on the IP board ‘health’ LED.
■ The Image Processor Board ‘health’ LED is turned off.
■ The front panel display is reset (addressable area becomes “gray”).
■ The Green LED turns on for 1/3 second.
■ The Yellow LED turns on for 1/3 second.
■ The Red LED turns on for 1/3 second.
■ The front panel LED is turned off.
■ The backlight is turned on (high intensity), with nominal contrast display.
■ The front panel display area is turned on, dark black for 1 second.
■ The front panel display is cleared.
■ The backlight is turned on with nominal intensity.
■ The POST Vn.nn message appears, and tests are quickly executed.
■ If any tests fail, the front panel screen freezes with the name of the test
displayed and the line posted is “Call Customer Service”.
■ After the POST tests have finished running, the Xerox ‘splash screen’ is
posted to the front panel and PostScript begins initialization.
Troubleshooting83
POST Faults
There are two kinds of faults: soft and hard.
A soft fault is any fault that is discovered by POST, but does not prevent the operating
system from initializing and becoming available as a tool for troubleshooting. These
POST faults do not stop execution and are reported on the StartPage in a red box after
the system is running.
A hard fault is any fault discovered by POST that prevents the operating system from
initializing successfully. A hard fault prevents the system from further execution and
is halted with blinking LEDs (front panel and health LED). The test name of the test
that failed is displayed on the front panel.
Fault Reporting Devices
There are four fault presentation devices.
■ All soft faults are printed on the StartPage.
For hard faults:
■ The health LED flashes according to the fault code.
■ The front panel LED flashes in unison with the health LED.
■ The last posted message to the graphic front panel is present.
LED Blink Patterns
For faults identified as hard faults, the POST firmware causes the PS health LED to
blink in a particular pattern to identify the fault. There are short and long blinks. A
long blink is worth 5 and a short blink is worth 1. If a fault blink pattern is flashed as
long, long, short, short, this is fault code 5+5+1+1=12, which indicates a failure in the
CPU interupt test, See “POST Diagnostics Test Descriptions” on page 85.
The exception to the above pattern is a RAM test error. The RAM tests have a special
blink pattern and the front panel displays “RAM Error”. During power up the front
panel LED is on. If the RAM tests fail, the Image Processor Board health LED is
turned off, and the front panel LED is red. At 1/2-second intervals, the health LED
and the front panel LED toggle continuously.

Description
(Hard) This test fails if the boot loader finds no RAM
present or faulty RAM.
Boot loader posts the message “RAM error” to the front
panel and blinks the front panel LED.
(Hard) This test determines if the I/O chip is functioning
properly.
(Hard) Performed during the POST firmware initialization
phase.
If the front panel is unplugged, a hard fault is indicated by
the heath LED.
(Hard) This test checks to see if the “i” button
(configuration chip) is present. If no chip is present the
test will fail and the front panel message “Please Install “i”
button” will display.
(Hard) This test checks addressing of the EEPROM.
(Hard) This test checks the ethernet core.
(Hard) This test checks that each interrupt source to the
CPU is functioning.
(Hard) This test checks that the USB core is functioning
properly.
(Soft) The real time clock is tested.
(Soft) This test examines bad or incompatible RAM
DIMMs.
(Soft) Checks that there is at least 128 Mbytes installed
and ignores more than 512 Mbytes.

This circuit stops all outputs if the 24 VDC, 5 VDC or 3.3 VDC power supply is
shorted. The circuit is reset when the short is removed, the power is turned off and
then on again.
Low-voltage Power Supply Overvoltage Protection Circuit
This circuit stops all outputs if the 24 VDC, 5 VDC or 3.3 VDC power supply
exceeds the specified voltage. The operating point is 32 VDC or more for 24 VDC,
7 VDC or more for 5 VDC, or 6 VDC or more for 3.3 VDC.
Fan Output Circuit
For the Fan Rear ON (H) signal, the output voltage varies depending on the status of
FAN LOW signal and FAN STOP signal.
