Load a new film pack. Refer to “Film loading procedure” on page 79. 78 2852 A EN 20070205 DRYSTAR AXYS Film loading procedure Procedure Open the empty input tray. WARNING: To avoid possible film jams, make sure to open input tray all the way. The printer is ready to start the loading procedure when the following message appears: Remove the white (protective) film sheet. 2852 A EN 20070205 79 DRYSTAR AXYS Take film pack, and open it. Verify that the film type on the film pack corresponds with the sticker on the tray! If you do use an other film type, you are advised to change the label on the tray. Note: You can put the film pack onto a table to make manipulation easier. Before you do this, make sure that the table is dust-free! 80 Remove the sticker from the film pack. 2852 A EN 20070205 DRYSTAR AXYS Remove the plastic film bag partially. Slide the film pack into the input tray, and remove the plastic film bag completely. 2852 A EN 20070205 81 DRYSTAR AXYS Tear the plastic strip around the film pack. Close 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. 82 2852 A EN 20070205 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 corner 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. 2852 A EN 20070205 83 DRYSTAR AXYS When the tray is closed, the Film Identification tag is read and the printer settings 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. 84 2852 A EN 20070205 4 Advanced operation (Key-operator mode) This chapter consists of the following topics: ❑ Overview of key-operator functions ❑ Quality Control for general radiography applications (DT 2 B & DT 2 C) ❑ Quality control for mammography application (DT 2 Mammo) (optional) ❑ Preventive maintenance schedule ❑ Cleaning the exterior ❑ Cleaning the print head ❑ Troubleshooting checklist ❑ Clearing of film jams ❑ Film identification problems DRYSTAR AXYS Overview of key-operator functions The key-operator menus make it possible to use the Drystar AXYS advanced functions.

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 mammography 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: Q Before 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 general radiography applications (DT 2 B and DT 2 C)” on page 88. Q After 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. 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. 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. 2852 A EN 20070205 87 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 establish 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 determined again after major service, repair or software update. The following Quality Control aim values must be determined: Q The daily operating density levels. Refer to “Establishing the daily operating reference density levels for general radiography applications (DT 2 B and DT 2 C)” on page 91. Q Drystar AXYS image geometry. Refer to “Establishing the image geometry reference 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 Resolution, Artifact Levels and Low Contrast Visibility for general radiography applications (DT 2 B and DT 2 C)” on page 96. 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 general radiography QC” on page 150. 88 2852 A EN 20070205 DRYSTAR AXYS On these charts, the following test conditions are also recorded: Q The type and serial number of the Drystar AXYS. Q The type and emulsion number of the film used to determine the reference values. Q The type of densitometer used. Q The time (day, month, year) that the values were established. WARNING: Before you can establish the daily operating levels, the Drystar AXYS must be switched on for at least 15 minutes and it must be calibrated as well. WARNING: Refer to “Switching on the Drystar AXYS” on page 48. 2852 A EN 20070205 89 DRYSTAR AXYS QC test image for general radiography applications (DT 2 B and DT 2 C) The QC image has several additional fields where the QC data can be filled in.

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 application. 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 quality 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: Q Before initial use, establishing a number of reference values that will be used for further follow-up and verifying initial image quality. Q Refer to “Establishing the daily operating reference density levels for mammography application (DT 2 Mammo) (optional)” on page 108. Q After establishing these values, performing regular daily, weekly and annual quality tests. Q Refer to “Performing quality control (QC) tests for mammography application (DT 2 Mammo) (optional)” on page 115. Note: Repeat the two main steps of the Hard Copy quality procedures for each input tray loaded with DT 2 Mammo films. 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 procedure.
