3 Obtaining Technical Support from Colortrac
Colortrac uses an online service desk facility called the Colortrac Global Help Desk to
manage requests for technical support for the T Series. The URL for the Help Desk is
www.colortrac-helpdesk.com. All requests for support for the T Series must be registered
via the Help Desk. By using the Help Desk, Colortrac may better manage support calls to
provide customers a better service.
For each support call, the Help Desk automatically raises a ticket. The ticket is the
means to communicate the progress and status of the support call, and other information.
Users may access and update ticket information through their User accounts at the Help
Desk URL.
3.1 Creating an Account
Distributors do not need to contact Colortrac to raise a Help Desk User account. The
Help Desk is programmed to accept new accounts that use specific email domains. But,
Distributors who find they cannot create a User Account should contact Colortrac
Technical Support.
3.2 User Profiles
We ask Users who log in for the first time to update their profile. Some information we
require and some we leave to the Users discretion to provide. But the more complete the
information provided the better Colortrac can provide support.
3.3 Submitting Requests for Support
To submit a request for support, Users must logon to the Help Desk and select the
'Request' icon. Dependant on the request type, Users will be asked to provide the
additional information Colortrac needs to progress the request quickly.
3.4 Asset Selection
Colortrac uses the Help Desk to associate support calls with scanner assets. For this
reason Distributors are requested to select the scanner associated with their request for
support. Those scanners a Distributor has received from Colortrac are listed at the
bottom of the page. Distributors may select the scanner the call is related to. If the
scanner is not listed please enter the serial number in the box provided.
3.5 Support Ticket Information
In the detail of each ticket Users can expect to see:
All pertinent information to the investigation
Regular updates on progress.
Requests for further information or activity.
The solution or outcome.

5 Safety
5.1 Safety Warnings
5.1.1 Electrical
Do NOT remove any covers from the scanner while the power is on or allow an end user
to operate the scanner with ANY covers removed. Engineers must exercise extreme
caution while working on any scanner.
It is advisable to allow the scanner 5 minutes to discharge before removing covers and
any of the boards. The boards may hold a charge and may give a shock if touched.
Please observe anti-static precaution when handling any
electrical boards from the scanner.
5.1.2 Mechanical
The mechanism that operates the lid and the paper handling assembly can trap fingers
when closing. Please handle with care.
5.1.3 Weight
Because the weight of the scanner is approximately 15Kg, 1 person can lift the scanner,
but 2 people are recommended to lift the scanner higher than chest height.
5.1.4 Rotating Rollers
The scanner operates a roller to move the image across the scanner. These rollers may
grip ties and any other similar articles of clothing, as well as long hair if put near the
rollers during operation.
5.2 EMC Testing
The T series model conforms to EMC and FCC (Part B). EMC testing is carried out to
ensure the T Series does not emit signals that can interfere with other devices, and that
no external interference signals will interfere with it.

6 Scanner Cautions
Do:
Recommend 2 people to lift the scanner onto the printer.
Keep the packaging for continued shipment of the scanner.
Calibrate the scanner on first installation.
Keep the Calibration target in a safe place for regular use.
Use the approved and supplied cables for the scanner.
Read the operator and installation manual before installation.
Fill out and return the installation form as soon as possible.
Do not’s:
Do not scan paper with any form of metal fastener or post-it notes
attached.
Do not allow the scanner to get wet.
Do not drop the scanner.
Do not stand the scanner on its end (packaged or un-packed).
Do not leave the scanner open for any length of time.
Do not stand on the scanner.
Do not balance the scanner on an unsafe surface.
Do not scan thick media that is beyond its maximum limit.
Do not unplug the scanner during a scan sequence.
Do not let an end user remove any panels from the scanner.
Do not use any other power supply other than the approved one
supplied with the scanner.
Do not install the scanner on an un-even surface.
Do not install in a dusty or dirty environment.
Do not allow the USB cable to be pulled forcefully out of the scanner.
NOTE: Before work is carried out on the
scanner the power MUST be switched
off and the power lead removed from the
scanner.
7 Photos Information
Some photos in this manual were taken during pre-production, and various stages of the
T Series development. Some colours / backgrounds / designs shown may vary from the
actual scanner being worked on. Some background panels may be shown in the photo to
be removed when they actually don’t need to be; however the instructions are still correct
and should be followed as described.

Manager.
8.1 Consumables

under warranty. Consumables can be purchased from Colortrac. Those T Series parts
considered to be consumables are:
SingleSensor Glass Sub-Assy.
Hold Up Roller Unit.
Calibration Target.
Pinch Rollers.
Timing Belts.

9 CIS Technology
A Contact Image Sensor (CIS) is an integrated module that comprises an illumination system, an
optical system and a light-sensing system - all within a single compact component.
The light-sensing system is the silicon surface
which is divided up into (e.g. 5000) discrete
square cells, the size of each being a fraction of
an inch depending upon the required scanning
resolution (a 600 dpi scanner will use a CIS
whose cells are 1/600" across). The optical
system is a rod lens array that directs light from
the document surface onto the silicon surface.
Such an optical system is 1:1; i.e. there is no
reduction or enlargement; and this results in a
scanner offering the best performance in terms of
resolving power and geometric accuracy.
The illumination of the document is provided by Light
Emitting Diodes (LED’s). The LED’s strobe rapidly Red,
Green, and Blue, providing the colour content in the
scan. Note that there are no colour filters in the optical
or light-sensing system. The colour gamut of a CIS
scanner is therefore determined by the spectrum of
each of the LED’s, rather than by colour filters as is the
case with CCDs.
However, rapidly strobed LED’s require no warm-up
period. Therefore, a CIS scanner can be switched on and used immediately. Furthermore, LED’s
are very stable which means that a CIS scanner does not require frequent re-calibration.

10 Scanner Accessories
10.1 USB Cable Type A and B
Length: 2 meter max.
Speed: 5Gbps
This high quality USB cable complies fully with
the USB 3.0 specification.
Transfer Speed ~ a new transfer type
called ‘Super Speed’ or SS – 5Gbps
More Bandwidth ~ uses 2
unidirectional data paths; one to
receive, one to transmit
Power Management ~ U0 through U3
link power management states are
defined.
Support to rotating media ~ Bulk
protocol is undated with a new feature
called Stream Protocol that allows a
large number of logical stream within
an Endpoint.
USB 3.0 has transmission speeds of up to 5 Gbps, which is 10 times faster than USB 2.0 (480
Mbps). USB 3.0 significantly reduces the time required for data transmission, reduces power
consumption, and is backwards compatible with USB 2.0.
USB 3.0 support can be added to existing laptop computers with only USB 2.0 and Expresscard
support by using an Expresscard-to-USB 3.0 adapter to supply USB 3.0 signal support. Although
the PCI Express port that the Express card connects cannot supply power of itself, the Express
card and hence the USB 3 ports nevertheless derive power from the USB 2 port that it
additionally connects to as part of the interface. If the
express card has more than one USB 3 port then only
100mA is available from each port. Additional power for
multiple ports may be derived in the following ways:
There have been some issues of USB 3.0 equipment only
transferring data at USB 2.0 speed, usually with a message
"This USB Mass Storage Device can transfer information
faster if you connect it to a Super-Speed USB 3.0 port".
This has been due to several causes, including drivers,
certain cables specified as USB 3.0 (problems disappeared
when a different cable was used), order of starting
equipment, equipment needing to be disconnected and
reconnected, and over clocked computers
NOTE:
Colortrac provides a USB 3.0 cable with each T Series. The use of a cable longer than 2m is at
the customer’s discretion. Colortrac is not responsible for errors that may occur as a result.
