Introduction
DenOptix® QST “Quad Speed Technology” System by Gendex®
DenOptix QST Intraoral (FMX) System
DenOptix QST Extraoral (E/O) System
DenOptix QST Intraoral and Extraoral System (Combo) System
Congratulations! Your decision to add the DenOptix QST System to your practice represents
a wise investment for the future of your practice.
The DenOptix QST is a revolutionary product designed to completely replace traditional X-ray
film and film processors. This system, built on phosphor imaging plate technology, offers the
following benefits:
• Diagnostic quality images — every time.
• Lowers the price of dental imaging by eliminating the need for costly film, chemistry and
film processors.
• Imaging plates are reusable.
• Saves critical time vs. using processing systems. DenOptix QST will process 4 bitewings in
under 30 seconds and a FMX will process 20 images in less than 4 seconds per image.
Panoramic images can be obtained in less than 80 seconds. A cephalometric image can
be obtained in less than 80 seconds.
• Significant reduction of X-ray dose as compared to D-speed film.
• It works with your current X-ray generating equipment. There is no need to purchase new
equipment.
• Reduces the hassles associated with the waste stream disposal.

It is important that all personnel who will operate the DenOptix QST System read and under-
stand this manual before operating the device. All personnel should follow all warnings and
cautions as outlined in Section 3.2, for their safety and the safety of others around them.
3.1 Important information
In this manual, the following definitions apply for all WARNINGS and CAUTION statements:
Warnings: Any operation, procedure or practice, which, if not strictly observed, may result
in injury or long-term health hazards to personnel or patients.
Cautions: Any operation, procedure or practice, which, if not strictly observed, may result in
destruction of equipment or loss of treatment effectiveness.
Warnings
Should be used only by trained professional.
Federal law restricts the sale of this device to physicians, dentists and dental professionals
only. Use of this device in procedures other than those described in this manual may result
in injury.
Do not open the device to service it.
None of the internal parts of the scanner are user serviceable. The only user serviceable parts

Gendex dealer or the Gendex representative nearest you.
3.2 Warning and caution statements

10
User and Service Manual Doc # M010-004WWE July 2005
Gendex DenOptix® QST
Do not place DenOptix QST near:
• X-ray equipment that is constantly energized (e.g., devices such as fluoroscopes which are
energized when not in use)
• Magnetic resonance imaging systems
• Large motor/electric generators
There is potential for electromagnetic interference between devices when using electronic
equipment. International standards exist to minimize this potential.
DenOptix QST has been tested against and complies with the international standard EN
60601-1-2, Medical Electrical Equipment - General Requirements for Safety - Collateral
Standard; Electromagnetic Compatibility Requirements and Tests, class A.
Use only grounded electrical connections.
Connect the DenOptix QST scanner to a grounded electrical outlet between 100-240 volts AC.
Do not reuse the barrier envelopes.
Once used within the oral cavity, the barrier envelopes are bio-contaminated and should
NEVER be reused. Please dispose of in accordance with Section 7.4.
Imaging plates are toxic!
Never place an imaging plate in a patient’s mouth without enclosing it first in a completely
sealed barrier envelope. If a patient swallows an imaging plate, contact a physician immedi-
ately. The physician must remove the imaging plate. Do not use cracked, bent or chipped
imaging plates.
Never open or override the lid lock when the scanner is in use or plugged in.
The scanner lid will lock during operation. In case of power failure, unplug the scanner and
open the lid by depressing the lock mechanism as indicated in Section 7.3.
Never use imaging plates with patients that might chew or swallow them.
If the patient bites or chews the plate and damages the protective barrier envelope, rinse the
patient’s mouth with a large amount of water. If the patient manages to swallow any of the
blue surface of the plate, contact a doctor immediately.
The DenOptix QST scanner is a Class 1 laser device.
Caution: Use of controls or adjustments or performance of procedures other than those spec-
ified herein may result in hazardous radiation exposure. A fail-safe switch in the carousel well
and cover keeps the laser inactive as long as the cover is open. Only a trained technician from
a qualified Gendex dealer should remove the cover from the scanner. Direct eye contact with
the output beam from the laser may cause serious damage and possible blindness.

Caution statements
Reduce the exposure time on your intraoral X-ray unit.
The DenOptix QST System is designed to produce high quality, diagnostic images at reduced
radiation levels. To get the maximum benefit, we recommend that the exposure be reduced
as outlined in Section 5.1.
Completely erase the imaging plates.
Before reusing an imaging plate, place it with the blue or white surface up facing a bright
light source for at least two (2) minutes as described in Section 5.2.
Mount the imaging plates under low light conditions.
Mount the imaging plates to the carousel under low light conditions as described in
Section 5.4. Exposure to direct sunlight or direct indoor lighting will erase the information
stored on the imaging plate.
Do not place scanner on or next to a radiator or water source.
Excessive heat or small amounts of water may damage the scanner’s electrical components.
Do not use in the presence of flammable anesthetics mixtures.
Do not autoclave the imaging plates.
Autoclaving will damage the imaging plate. If this happens, discard the imaging plate and
replace it with a new one. If an imaging plate becomes contaminated, follow the procedure
described in Section 5.6.
Do not leave unscanned, exposed imaging plates in light.
Leaving unscanned, exposed imaging plates in light will cause severe loss of image quality.
If left exposed for long time, or to bright light, the image may be erased entirely.
Do not scratch the imaging plates.
When handling the imaging plate, do not touch the active side (blue or white) any sharp
object that might scratch the surface. Do not lay unprotected imaging plates face down.
