Operating the System
Now that you have made all the necessary connections (and loaded your
software) you are ready to operate your system. The heart of the Scanning
Instrument is the compact, scanning head. The ATD Sheet head moves along
the track at approximately 150mm/sec. The ATD News head moves along
the track at approximately 8in./sec. After a measurement, the scanning head
uploads the data to the computer via RS-232 communications.
This section covers instrument calibration, sheet loading and alignment, and
measurement procedures.
Refer to your software documentation or on-line help for information
regarding software operation.
Calibrating the Scanning Instrument is virtually automatic, there is no
calibration reference to position. The Calibration References are a
permanent part of the Track assembly—located near the Docking Station.
The references are covered by a retractable cover when the Scanning Head
is away from the Docking Station, and exposed when the scanning head is
next to the docking station.
The Scanning Head automatically calibrates to the references when required
or when you request it.
Retractable Cover

NOTE: The calibration references should be cleaned periodically to
maintain calibration accuracy. Refer to Section Three, General Cleaning for
procedure.

SHEET LOADING AND ALIGNMENT
Loading a press sheet or paper onto the Scanning Instrument is fast and
easy. There are no guides or clamps to adjust. The press sheet or paper is
loaded onto the track from the back over the plate that contains the vacuum
holes and LED’s (if a feed-through track). A vacuum is created once a
measurement sequence is started, holding the press sheet or paper in place.
The sheet or paper should be placed 90mm away from the docking station
or centered on the track, and at least 60mm away from the end of the track.
Standard Track Positioning
The press sheet must be positioned against the “sheet stops” that run along
the back edge of the vacuum plate. The color bar on the sheet cannot be
over 38mm from the paper’s edge.
In the event that a color bar is not properly aligned on a press sheet (this is
recognized during a job setup), the scanning system takes corrective action
by automatically adjusting the ATD scanning head. This ensures all color
patches are measured accurately even when a color bar is slightly skewed.

Feed-Through Track Positioning
The feed-though track allows measurements at any location within the
paper. This is possible because the track has a slotted opening, allowing the
paper to be slide through the track.
The gray balance bar or color masthead bar is easily position on the track
using a series of LED’s that illuminate from the track through the paper.
The LED’s are located between the vacuum holes approximately every 5
inches along the track. Open the paper and position it so the LED’s are
shining down the center of the bar. The LED’s automatically shut off once
the scanning head starts in motion.

TAKING A MEASUREMENT WITH THE ATD SHEET
INSTRUMENT
After the press sheet is properly positioned on the track, you are ready to
perform a color bar recognition/measurement. The sequence is started in
one of two ways: by selecting the recognition/measurement function from
the Software, or by pressing the Operation button located on top of the
Docking Station.
Once a scan is set in motion, the vacuum pump activates and the “green”
light on the station changes to “yellow,” indicating a scan is in progress.
The scan head travels the entire length of the track before returning to the
docking station. If additional color bars are located on the opposite edge,
you will need to change sides. The software informs you when this is
required. Refer to your software documentation for additional information.
If a problem is encountered during a measurement, the scanning head
immediately returns to the docking station. View your computer monitor to
see if an error message is displayed. If no message is displayed, try to
rescan sheet; if a problem still occurs, refer to the Troubleshooting section
in this manual.

INSTRUMENT
After the newspaper is properly positioned on the track, you are ready to
perform a measurement. Press the Operation button located on top of the
Docking Station once to activate the vacuum pump. Then, press the button
again to start the measurement sequence.
Once a scan is set in motion, the “green” light on the station changes to
“yellow,” indicating a scan is in progress. The scan head travels the entire
length of the paper before returning to the docking station. Refer to your
software on-line help for specific information on the software operation.
If a problem is encountered during a measurement, the scanning head

General Maintenance
This section will cover the maintenance procedures for the system.
Section Contents
• Repair Information ........................... 3-1
Your ATD System is covered by a three-year limited warranty and should
be referred to the factory for repairs within the warranty period. Attempts to
make repairs within this time frame may void the warranty.
X-Rite provides a factory repair service to their customers. Because of the
complexity of the circuitry, all repairs should be referred to the factory.
X-Rite will repair any ATD System past warranty. Shipping cost to the
factory shall be paid by the customer, and the instrument shall be submitted
in the original carton as a complete, unaltered unit.
OVERVIEW
The System requires little preventative maintenance to achieve years of reliable
operation. However, to protect your investment and maintain measurement
accuracy, a few simple cleaning procedures should be performed.
SCANNING HEAD
NOTE: DO NOT use any solvents or harsh cleaners of any kind.
NOTE: DO NOT move the trolley up and down the track manually without
the scanning head attached.
In the course of normal use, spray powder, paper dust, and other airborne
contaminants will likely enter the instrument's optics. This can eventually
reduce the sensitivity of the instrument and may lead to calibration errors.
Follow the steps below to clean the optical components.

- Re-connect the power to the track.
Page 27
G E N E R A L M A I N T E N A N C E
5. Note that the process of cleaning the optics will affect the instrument's
sensitivity as dust and powder will no longer block the optical path. It is
essential that the head be fully calibrated following the cleaning process.
6. The exterior of the scanning head and docking station can be wiped
clean with a lint-free cloth dampened in water or a mild cleaner.
Maintenance
1. Replace the five (5) Read Head Pogos if they display any signs of
wear or discoloration.
2. On newer read heads, replace the Paper Stop Push Plate if anodize is
broke or worn through.
SCANNING TRACK
NOTE: DO NOT reverse the intake/exhaust port on the vacuum to blow
out the track vacuum chamber. This will force any dust inside the track into
the read head optics.
NOTE: DO NOT use any solvents or harsh cleaners of any kind.
NOTE: DO NOT use any type of lubrication (oil) on any part of the system.
Cleaning (1 to 2 time a month)
1. The exterior of the docking station can be wiped clean with a lint-free
cloth dampened in water or a mild cleaner.
2. The track can be wiped clean with a lint-free cloth dampened in glass
cleaner. When cleaning the track, make sure to clean the entire track.
This includes the portion of the track that resides under the reading
head when it is in its docked position. You can simply slide the head
over when cleaning is required.
3. Inside of track assembly – use compressed air to remove all print dust.
