Device Description
Technical Specifications
e Stryker X8000 Light Source is a light-generating unit
designed to illuminate surgical sites during endoscopic
applications. e X8000 uses a 300-watt xenon bulb to
generate light, which it delivers to the surgical site via a
beroptic light cable.
e X8000 is compatible with all Stryker light cables, and,
with the proper light cable and adapters, can connect to any
exible or rigid endoscope.
e X8000 is equipped with Electronic Scope Sensing
Technology (ESST), a special safety feature that helps
prevent accidental burns caused by a light cable that is
not connected to the scope. When operated with an ESST
light cable, the X8000 senses when the scope and the light
cable are separated and places the light source in Standby
mode. In Standby mode, the X8000 will reduce light output
to a minimum, preventing the light cable from generating
excessive heat.

Basic Maintenance
Replacing the Bulb Module
Cleaning the X8000
Caution Unplug the X8000 before cleaning the
unit.
1. As needed, clean the external surfaces of the X8000
using a cloth or sponge dampened with a mild
detergent or disinfectant.
2. Clean and maintain the light cable according to the
manufacturer’s instructions.
Caution Do not use any abrasive cleaners. Do not
allow any liquid to drip into the unit.
Caution Do not sterilize or immerse the X8000.
Caring for the Bulb Module
e X8000 uses a Xenon bulb, which has a guaranteed
life of 500 hours when used properly. Always follow these
guidelines to ensure maximum bulb life:
1. If the bulb is touched, clean the bulb face with
alcohol and a cotton swab. Dirt or oil on the bulb
face will cause the bulb to heat unevenly and fail.
2. Do not power on and o the bulb in rapid
succession. Allow the bulb to run for at least ve
minutes once it has been powered on. Failure to do
so can cause the bulb to rapidly darken and fail.
Replace the bulb module when the LCD indicates 500 hours
or when the bulb no longer suciently illuminates the
surgical site. If possible, replace the bulb module between
surgical procedures.
Warning During operation, the bulb and the
housing around the bulb may be hot.
Wa it at least three minutes for the bulb
to cool before handling it.
To replace the bulb module,
1. Power down the X8000 and wait at least three
minutes for the bulb to cool.
2. Open the bulb door.
3. Rotate the bulb module handle to the right, grasp it,
and withdraw the bulb.
Warning Do not reach inside the bulb door for
any reason other than replacing the bulb
module. Touching parts other than the
bulb module may cause burns or product
damage.
Warning Do not touch any part of the bulb module
except for the handle. e module may be
very hot and cause burns.
Caution e X8000 has been designed to start the
bulb under most conditions, even when
it is hot. However, if the bulb does not
start within 10 seconds aer the X8000
has powered on, turn the unit o and
wait at least ve minutes for the bulb to
cool before restarting. Further attempts
to start the bulb can damage the bulb and
possibly the internal circuitry.
10
4. Insert the new bulb module (Stryker part number
220-201-000) along the guide rails until it is fully
seated on the mating connectors.
5. Rotate the handle to the le to secure the bulb
module within the light source.
6. Close and latch the bulb door.
7. Power on the unit.
8. Power on the bulb (if not already on) and verify that
the LCD displays the bulb hours as “0.”
Note Using a non-Stryker replacement bulb
module will result in no light output.
Caution Do not operate the X8000 with a burned-
out bulb or with no bulb installed.
Replacing the Fuses
1. Unplug the light source from the AC outlet and
remove the power cord from the rear of the unit.
2. Unlatch the fuse holder and remove the fuse(s).
3. Replace the fuse(s) with fuse(s) of the same
value and rating.
Warning To help avoid the risk of re, use only
5.0A 250V fuses.
4. Reinstall the fuse holder.
Disposing of the X8000
is product is considered electronic
equipment. It must not be disposed of
as unsorted municipal waste and must
be collected separately. Please contact
the manufacturer or other authorized
disposal company to decommission
your equipment.

Troubleshooting
Problem Possible Solution
No light output
• Ensure the AC power cord is properly connected to a hospital-grade power outlet and
the inlet on the rear console panel.
• Ensure the power switch on the front panel is powered on. (It will illuminate when
powered on.)
• Ensure all fuses are operating.
• Ensure the bulb is properly seated in the bulb housing. e bulb handle should be
turned all the way to the le within the light source.
• Ensure the bulb is in operating condition. Replace the bulb if necessary.
• Ensure the light cable is correctly engaged with the cable port. As a safety feature, the
X8000 will provide no light output unless a beroptic light cable is properly seated in
the cable port.
• Ensure the bulb access door is completely shut.
• Check for error codes E-1, E-2, E-3, E-4 or E-5. See the Error Code Denitions section
of this manual for details.
• Check that vents are not obstructed.
• If the safety shuto has been activated, please return the X8000 for service. Please see
the Component Replacement section of this manual for additional information.
To o much or too little
light output
Excessive glare in the
video
• Ensure the light cable is correctly engaged with the cable port.
• Ensure the bulb has adequate bulb life remaining. e bulb has a warranty of 500 hours.
• Ensure the X8000 is in Run mode. (e Run LED should be illuminated.) If necessary,
press the Mode button to switch from Standby to Run. If the unit remains in Standby:
1. Ensure the light cable is correctly engaged with the cable port.
2. If an ESST cable is connected to the X8000, ensure the cable is attached to the scope
using an ESST scope adapter.
• Use the up/down buttons to adjust the brightness.
• Ensure the beroptic cable is transmitting light properly. Hold the light-source end of
the cable to an overhead room light and look into the scope end of the light cable. If
the pattern contains any black spots, the light cable may be worn out and may require
replacement.
• Ensure the light cable is of an adequate size for the application. e cable diameter may
be too small to provide adequate light transmission for the medical video camera in the
endoscopic application.
• Ensure the electronic shutter on the camera is operating properly to control the video
signal brightness. If further light reduction is required, decrease the light source
brightness with the down button.

Diagnosis
To diagnose system errors, follow the strategies provided
below. For steps that involve test points on the control
board, refer to the control board diagram at the end of the
Diagnosis section.
Diagnosis strategies are grouped by symptom:
A. Bulb does not turn on
B. Bulb does not turn o
C. Bulb ignites immediately upon system startup
D. LCD display is blue or completely dark
E. Fan does not run
F. Light source does not switch from STANDBY to
RUN mode
G. Brightness cannot be adjusted
H. E-1 error appears on the LCD display
I. E-2 error appears on the LCD display
J. E-3 error appears on the LCD display
K. E-4 error appears on the LCD display
L. E-5 error appears on the LCD display
M. Bulb hours value does not display
N. Shutter makes noise or does not move properly.
A. Bulb does not turn on
1. Check the voltages on the control board test points
TP22 and TP23.
• If the test points read 12V and 0V respectively,
then the ballast is faulty. Replace the ballast.
• If the voltages are in the vicinity of 5.5V and
7V respectively, proceed to step 2.
2. Visually check if the bulb door is properly
closed with the cover or a stand-alone magnet. If
necessary, close the door.
3. Visually check if the light cable is properly inserted
into the jaw. If necessary, reinsert the cable.
4. Visually check if the bulb has the one-wire memory
chip. If it does, ensure the chip makes contact with
the bulb mount board connector. If necessary,
adjust contact between the chip and the connector.
5. Using a multimeter, electronically check the
following test points on the control board. Each test
point should read 3.3 volts.
• PD1—reads 3.3 volts if the one wire chip is
detected by the control board. If PD1 reads 0
volts (and PD2 reads 3.3 volts), try a dierent
bulb. Push the bulb rmly towards the plastic
separator panel to ensure contact.
• PD2—reads 3.3 volts if the door reed switches
are closed. If PD2 reads 0 volts,
- Check if the reed switches on the bulb
mount boards are soldered properly. If
necessary, repair the soldering.
- Check for shorts using the magnet on the
reed switch. Repair/replace as necessary.
- Check if the cable wire colors are
correctly oriented. Adjust as necessary.
• PD3—reads 3.3 volts if the fans are functioning
properly
• PD4—reads 3.3 volts if a regular light cable is
inserted. If PD4 reads 0 volts, remove the front
panel and check if the beam sensor is properly
positioned and connected to the display board.
Adjust as necessary.
• PD5—reads 3.3 volts if an ESST light cable is
inserted. If PD5 reads 0 volts, remove the front
panel and check if the beam sensor is properly
positioned and connected to the display board.
Adjust as necessary.
6. If none of these help, contact Technical Support at
+1.800.624.4422.
B. Bulb does not turn o
If the bulb turns on immediately aer AC power is applied
to the light source, proceed to diagnosis strategy C, “Bulb
ignites immediately upon system startup.”
If the bulb ignites aer the regular startup sequence but then
will not turn o, perform the following steps until the source
of the problem is identied.
1. Remove the light cable from the jaw.
2. Open the bulb door or remove the magnet from the
reed switches.
3. Using a multimeter, check the following test points
on the control board:
• PD2—If PD2 reads 3.3 volts, the reed switches
are faulty. Replace the reed switches.
• PD4 and PD5—If either PD4 or PD5 reads 3.3
volts, the light cable sensor (beam sensor) is
faulty. Replace the light cable sensor.
4. If PD4 or PD5 reads 0 volts, measure the voltage
dierence between TP22 and TP23.
• If the voltage dierence is around -1.3 volts,
replace the ballast.
• If the voltage dierence is around 12 volts,
proceed to step 5.
5. Measure the voltage level for TP32.
• If TP32 reads 0 volts, replace the control board.
(See the Repair/Replacement Procedures
section of this manual.)
• If TP32 reads 3.3 volts, proceed to step 6.

replace the control board (See the Repair/
Replacement section of this manual.).
E. Fan does not run
1. If one or both fans are not working, an E-4 (ballast)
or E-5 (bulb) error should display on the LCD
screen. Conrm this.
2. If both fans do not work, measure the voltage on the
10.2V test point on the control board (underneath
lamp status connector).
• If it does not read around 10.2 volts, replace
the control board (See the Repair/Replacement
section of this manual.).
3. If only one fan works, switch the fan connectors
between the working and non-working fans.
• If non-working fan still fails to run, then it is
faulty. Replace it. (See the Repair/Replacement
section of this manual.)
• If the non-working fan begins to run, but the
working fan stops running, then the control
board is faulty. Replace it. (See the Repair/
Replacement section of this manual.).

1. Make sure that the light cable is inserted, the bulb
door is closed with a bulb inside, and the lamp is
not lit.
2. Check the voltages on TP22 and TP23.
• If the voltage dierence between TP22 and
TP23 is not 12V, replace the control board.
• If the voltage dierence between these two test
points is 12V, ensure the J3 cable is connected
properly to the ballast and that the individual
wires are not crossed.
- Ensure that L3 and L4 ferrites, located
underneath the J3 connector, are
soldered properly to the control board.
- If these ferrites are missing, broken, or
not soldered properly, repair or replace
the control board.
3. If none of the above steps resolves the problem,
replace the ballast.
I. E-2 error appears on the LCD display
1. Make sure that the bulb is lit and the light is on.
2. Repeat diagnosis strategies B and C, respectively.
J. E-3 error appears on the LCD display
1. Probe TP13 with a multimeter.
• If it reads 3.3 volts, and E-3 still appears on the
display, replace the control board.
• If the voltage on TP13 is low, replace the
ballast.
K. E-4 error appears on the LCD display
1. Verify that the ballast fan is not running.
2. Ensure the ballast fan is connected to the control
board.
3. If the fan seems to be working, visually compare the
speed of the ballast fan to the bulb fan.
• If the ballast fan seems to be running slower,
replace the fan and verify that the E-4 error
disappears.
• If the E-4 error does not disappear with the
new fan, replace the control board.
L. E-5 error appears on the LCD display
1. Check to verify that the bulb fan is not running.
2. Ensure the ballast fan is connected to the control
board.
3. If the fan seems to be working, visually compare the
speed of the bulb fan to the ballast fan.
• If the ballast fan seems to be running slower,
replace the fan and verify that the E-5 error
disappears.
• If the E-5 error does not disappear with the
new fan, replace the control board.
M. Bulb Hours value does not display
1. Connect a regular light cable to the light source.
2. Make sure there is a bulb in the light source, close
the door, and verify that it is lit.
3. Verify that there is a one-wire memory properly
attached.
4. Verify that the one-wire memory is making contact
with the connectors on the bulb mount board.
5. If the bulb does not light, perform diagnosis
strategy A.
6. If you are unsure about the proper contact, insert a
new bulb to see if the hours will display.
7. If the hours still do not display, verify that the cable
between the bulb mount board and the control
board is properly connected.
8. If the cables are properly connected, but the hours
still do not display, replace the control board.

N. Shutter makes noise or does not move
properly.
1. Check the pinouts of the motor cable and the bulb
mount board/control board cable. Make sure the
wire colors match the drawing.
2. Make sure the connectors J1 and J2 on the bulb
mount board are not soldered in the wrong
direction.
3. Make sure the minimum shutter switch is soldered
properly. Make sure the switch lever is properly
connected to the switch itself.
4. Make sure the shutter wheel is properly connected
to the motor sha.
5. Make sure the shutter wheel is not rubbing against
the hot mirror holder.
6. If the motor is rotating the shutter in the reverse
direction when power is applied to the light source,
replace the motor.
7. If the motor is hesitantly rotating the shutter back
and forward, then replace the motor.
8. If the shutter’s mini tab is catching the bottom
of the minimum shutter switch, replace the bulb
mount board.
9. If none of the steps above solves the problem,
contact Technical Support at +1.800.624.4422.

Repair/Replacement
e X8000 Light Source is a precision instrument that has
been engineered and manufactured with great care to ensure
the safety of operators and patients. In order to maintain the
high level of safety and reliability required in devices of this
nature, it is important to fully understand and comply with
all required procedures set forth herein.
If some part of a procedure is omitted or adequate equipment
is not used, the safety and performance of the devices may
be unknowingly compromised. If any of the procedures
described in this manual are beyond the scope of the
technician’s training, consult the “Service Options” section of
this manual for information on how to obtain service from
Stryker Endoscopy.
As is the case with all AC powered
devices, dangerous voltages are present.
If adequate safety precautions are not
taken, results may include damage to the
equipment, personal injury, or death. It
is imperative that these procedures are
approached only by trained technicians
with proper equipment aer fully reading
and understanding the steps involved.
Note For all steps that involve the application of
Loctite, apply Loctite to the threaded holes
rather than to the threads on the screws
unless otherwise specied.
Note When using a power screwdriver, set
torque setting to 3 high unless otherwise
specied.
Each of the following tables provides repair/replacement
instructions for specic components of the X8000. For each
instruction, the required tools, equipment, and replacement
part numbers are provided.
Caution ESD Protection is required to perform
this assembly. Failure to follow this
procedure can cause undetectable
damage to electrical components.
