Press the Up/Down arrow keys to select the desired tray, followed by the
5
Confirm key.
The following screens appear successively:
The Drystar 5302 will automatically print the QC test image.
After the image is printed, the system will display the optical density values:
6
DD: 1.56
(Densitometer=MB924)
The displayed values represent the following steps on the test film:
Low density
Mid density
High density
Base + Fog,
Density difference
(DD),
Maximum density
(Max D)
If the mid density value does not meet or exceeds the recommended
values, the reason must be found and the problem solved before any
further clinical films can be printed.
