Managing the print queue
Checking the print queue
You can always check the status of the print jobs on a connected remote access
PC via the operator menu.
If jobs have been transmitted from the network to the Drystar AXYS, they are
put in the print queue on a first in, first out schedule. New jobs that are added to
the queue get the ‘waiting’ status.
As soon as the last film of a job is ejected in the output tray, the next job that has
been calculated will be put in printing status.
Note: Keep in mind that one print job can hold several films to be printed. In
accordance with the acquisition modality used and with the actual settings,
films can be grouped in a folder to be submitted as one print job for the
Drystar AXYS. Refer to the User manual of the acquisition modality for more
information.

The Drystar AXYS will inform you in several ways when a film tray is empty:
Qan audible signal,
Qthe status indicator LED is blinking (red color),
Qthe display screen shows a message informing you that the input tray is empty.
The film loading procedure is identical for both input trays. In the examples
below, we will assume that the lower input tray is to be loaded.
Note: The Drystar AXYS can be loaded with new films in full daylight. Loading
films is easy and can be done very quickly. Follow the procedures as described in
this section.
Note: If you want to change the film format, the tray configuration must be
modified. Refer to “Changing the film format of the trays” on page 32 for more
information.
Note: The procedure is slightly different, depending on the fact whether the
Drystar AXYS is printing/calculating or in the ready state.
Note: When the printer is in the ready state, go to “When the Drystar AXYS is in the
ready state and an input tray is empty” on page 78.

9Close the input tray.
Note: The Drystar AXYS resumes printing as soon as the tray is closed.
Note: Loading instructions are also available on the input tray cover.
Note: Never load another film format when the input tray is not empty.
Intermediate changing of film formats increases the risk for dust, which can
damage the thermal print head (TPH).
Note: The system performs an automatic calibration when the film format has
been changed.
Note: When a film job cannot be done because the tray to which the job is assigned
is empty, then the printer will check if the films in the other tray can be used for
this and other print jobs in the print queue. The printer will skip the print jobs that
cannot be done and will resume them later.
Note: When a film sheet is inserted wrongly in the input tray, then the printer will
print on the back-side (non-emulsion side). As a result, a film jam occurs.
Note: The operator will be informed of this back side printing and will be asked to
remove the film jam (refer to “Clearing of film jams” on page 129) and to check
whether the loading procedure was followed correctly (refer to “Film loading
procedure” on page 79).
WARNING: Never reuse a jammed film. Refer to “Clearing of film jams”
on page 129.

DRYSTAR AXYS
Checking the correct position of a
film in the input tray
You can verify that the film is properly loaded by watching the lower right cor-
ner of the films in the input tray. The rounding of this corner should be smaller
than the other three corners. This is also indicated on the sticker at the right
side of the input tray cover.

When the tray is closed, the Film Identification tag is read and the printer set-
tings are automatically adjusted if the film properties have changed. The Film
Identification tag is located on the protective sheet on the backside of the film
pack. The figure below shows the film pack upside down.
Note: For some new film types, the Film Identification tag will be covered by a
sticker and therefore will not be visible.

DRYSTAR AXYS
Quality Control for general
radiography applications (DT 2 B &
DT 2 C)
In order to establish and maintain consistent image quality, a regular evaluation
of image quality is advised.
The Drystar AXYS contains an automatic QC procedure for general radiography
applications and has been designed to comply with the grayscale reproduction
constancy test, according to the international standard IEC 1223-2-4. If the
option for the mammography application is activated, another QC procedure is
available for the mammography application (refer to “Quality control for mam-
mography application (DT 2 Mammo) (optional)” on page 104. In this chapter
we will discuss how to control the quality of general radiography applications.
Local Regulations may require other procedures.
The Drystar AXYS Hard copy quality control procedure consists of two main
steps:
QBefore initial use, establishing a number of reference values that will be used
for further follow-up and verifying initial image quality.
Refer to “Establishing the reference values and verifying image quality for gen-
eral radiography applications (DT 2 B and DT 2 C)” on page 88.
QAfter establishing these values, performing regular daily, weekly and annual
quality tests.
Refer to “Quality Control for general radiography applications (DT 2 B &
DT 2 C)” on page 87.
The results of these tests are recorded on Quality Control Charts.
The QC image (Refer to “QC test image for general radiography applications
(DT 2 B and DT 2 C)” on page 90) has several additional fields where the QC
data can be filled in. This image should be filed as part of the QC procedure.
For more information, please refer to “Quality Control Charts” on page 149.
Note: Repeat the two main steps of the Hard Copy quality procedures for
each input tray loaded with DT 2 B and/or DT 2 C films.
88 2852 A EN 20070205
DRYSTAR AXYS
Establishing the reference values
and verifying image quality for
general radiography applications
(DT 2 B and DT 2 C)
After installation of a new Drystar AXYS and before initial use you must estab-
lish Quality Control aim values. These values will be used as the base line for
comparison when daily Quality Control is done. These values should be deter-
mined again after major service, repair or software update.
The following Quality Control aim values must be determined:
QThe daily operating density levels. Refer to “Establishing the daily operating ref-
erence density levels for general radiography applications (DT 2 B and DT 2 C)”
on page 91.
QDrystar AXYS image geometry. Refer to “Establishing the image geometry refer-
ence values for general radiography applications (DT 2 B and DT 2 C)” on
page 95.
Once Quality Control aim values are established you must evaluate the Spatial
Resolution, the Artifact Levels and the Low Contrast Visibility to determine if
the image quality is acceptable. Refer to “Verifying Acceptable Spatial Resolu-
tion, Artifact Levels and Low Contrast Visibility for general radiography applica-
tions (DT 2 B and DT 2 C)” on page 96.

Quality control for mammography
application (DT 2 Mammo) (optional)
In order to establish and maintain consistent image quality, a regular evaluation
of the image quality is advised.
The Drystar AXYS contains an automatic QC procedure for general radiography
applications (refer to “Quality Control for general radiography applications
(DT 2 B & DT 2 C)” on page 87). If the option for the mammography application
is activated, another QC procedure is available for the mammography applica-
tion. This QC procedure has been designed to comply with the NEMA Standards
publication XR 23-2006. In this chapter we will discuss how to control the qual-
ity of mammography applications. This procedure is automatically selected
when there is Mammo media in the input tray.
Local Regulations may require other procedures.
The Drystar AXYS Hard Copy quality control procedures consist of two main
steps:
QBefore initial use, establishing a number of reference values that will be used
for further follow-up and verifying initial image quality.
QRefer to “Establishing the daily operating reference density levels for mammog-
raphy application (DT 2 Mammo) (optional)” on page 108.
QAfter establishing these values, performing regular daily, weekly and annual
quality tests.
QRefer to “Performing quality control (QC) tests for mammography application
(DT 2 Mammo) (optional)” on page 115.
The results of these tests are recorded on Quality Control Charts.
The QC image (refer to the “QC test image for mammography applications
(DT 2 Mammo) (optional)” on page 107) has several additional fields where
the QC data can be filled in. This image should be filed as part of the QC proce-
dure.
For more information, please refer to “Quality Control Charts” on page 149.
Note: Repeat the two main steps of the Hard Copy quality procedures for
each input tray loaded with DT 2 Mammo films.

Establishing the reference values
and verifying image quality for
mammography application
(DT 2 Mammo) (optional)
After installation of a new Drystar AXYS and before initial use you must estab-
lish Quality Control aim values. These values will be used as the base line for
comparison when daily Quality Control is done. These values should be deter-
mined again after major service, repair or software update.
The following Quality Control aim values must be determined:
QThe daily operating density levels. Refer to “Establishing the daily operating ref-
erence density levels for mammography application (DT 2 Mammo) (optional)”
on page 108.
QDrystar AXYS image geometry. Refer to “Establishing the image geometry refer-
ence values for mammography application (DT 2 Mammo) (optional)” on
page 112.
Once Quality Control aim values are established you must evaluate the Spatial
Resolution, the Artifact Levels and the Low Contrast Visibility to determine if
the image quality is acceptable. Refer to “Verifying Acceptable Spatial Resolu-
tion and Artifact Levels and Low Contrast Visibility for mammography applica-
tion (DT 2 Mammo) (optional)” on page 113.
The Quality Control aim values, the Spatial Resolution and Artifact Levels and
the Image Geometry values are all recorded on the Quality Control charts. Refer
to “Charts for mammography QC (optional)” on page 155.

Performing the Weekly QC tests for mammography
application (DT 2 Mammo) (optional)
Spatial Resolution, Artifact Test and Low Contrast Visibility
To identify artifacts and verify spatial resolution you must perform the follow-
ing test weekly or as needed for troubleshooting image quality problems.
Procedure
1First, print out the QC mammography test image. Refer to “Performing the daily
QC test for mammography application (DT 2 Mammo) (optional)” on page 116.
2Check the QC test image visually for artifacts: no significant disturbing artifacts
should be visible.
3Check the spatial resolution.
The test film also shows three squares which each contains an oval. These 3 ovals con-
tain 3 groups, each having 5 dots. All five dots of each group must be visible with a
magnifying glass. The smallest cluster of 5 dots is only visible if the viewing conditions
are good.
4Check the Low Contrast Visibility at both the high (100 / 95%) and low end
(0 / 5%) of the density scale. You should be able to see the circle in the square
(refer to item 1 on the “QC test image for mammography applications
(DT 2 Mammo) (optional)” on page 107) and the upper circle (refer to item 2
on the “QC test image for mammography applications (DT 2 Mammo)
(optional)” on page 107).
WARNING: Good viewing conditions are important for the correct
interpretation of both diagnostic and test images. Make sure that the light
box intensity (luminance) is 3000 and 6000 cd/m² (4500 and 6500 °K)
for mammography. Use a magnifying glass and use shutters to collimate.
Make sure the ambient light is low.

5Record these values on Chart 3 (‘Drystar AXYS Artifacts and Spatial Resolution
Control Chart’). Refer to “Charts for mammography QC (optional)” on
page 155.
WARNING: In case of significant artifacts, insufficient spatial
resolution or failure of any other recommended QC tests, the
cause of the problem must be identified, and corrective action
must be taken before the Drystar AXYS can be used for any further
clinical imaging.
WARNING: Refer to “Preventive maintenance schedule” on
page 121 and “Maintaining image quality and resolving image
quality problems” on page 258 (Reference manual), or call your
local Agfa service organization.

Performing the Annual QC tests for mammography
application (DT 2 Mammo) (optional)
Geometric Consistency Test
To be able to notice fluctuations in image size and aspect ratio, you must per-
form this procedure once a year.
Procedure
1First, perform the daily test.
2Measure the distances A and B of the geometric square on the QC mammogra-
phy test image. Refer to “Establishing the image geometry reference values for
mammography application (DT 2 Mammo) (optional)” on page 112.
3Record these values as measured distances A and B on Chart 4 (‘Drystar AXYS
Geometric Consistency Control Chart’). Refer to “Charts for mammography QC
(optional)” on page 155.
4Compare the measured A and B dimensions with the reference dimension val-
ues, Aref and Bref on Chart 4 (‘Drystar AXYS Geometric Consistency Control
Chart’). Refer to “Charts for mammography QC (optional)” on page 155.
The differences between the measured dimensions of A and B and the reference val-
ues A ref and B ref should be less than or equal to 1.0%.
5Check for image distortion.
6Calculate the aspect ratio by dividing A by B.
The result must be 1 +/- 0.01
WARNING: Make sure to measure distance A from the left edge of
the left line to the right edge of the right line and distance B from
the upper edge of the upper line to the lower edge of the lower
line.
WARNING: We strongly recommend using a 30 cm (12-inch)
machinist scale with 0.5 mm divisions (1/64 inch).
WARNING: If the image size or distortion values are outside of
limits, contact Agfa service to resolve the problem.
