Calibrating Film; Choosing Not To Calibrate A Media Cassette - Codonics HORIZON G1 Bedienungsanleitung

Before cleaning the platen, you must manually move the print head to the shipping position. Refer to
the procedure above under "Changing the Print Head Position."
Also, the latest versions of the imager do not support jogging the platen from the front panel. When
cleaning the platen, you have to use your fingers to manually jog the platen so that you can clean its
entire surface. Make sure that you clean the areas where you have touched the platen to remove any oil
from your fingers.
Otherwise, you can follow the procedure as described in "Cleaning the Platen and Donor Guide Bar" in
the Horizon Imager User's Manual.
The alcohol concentration of the Platen cleaning pad is 70% IPA.

Calibrating Film

The latest versions of the imager do not support internal film calibration. To calibrate film, you have to
print a calibration film, use an external densitometer, and enter a calibration adjustment value.
To calibrate the film for a media cassette:
1. Insert the media cassette.
If the Auto Film Calibrate preference setting is set to On, a calibration film is printed automatically.
(For more information about the Auto Film Calibrate preference setting, refer to the Horizon Imager
Technical Manual.)
If the Auto Film Calibrate setting is set to Off, on the front panel navigate to and select the
Calibration Print menu option corresponding to the slot in which the cassette is inserted:
Utilities...
Film Calibration...
Cassette n...
Calibration Print
The calibration film includes 16 grayscale blocks with a range of optical densities. The calibration
film also includes the slot number to identify the cassette to which it corresponds.
2. Measure the 16 blocks and identify the two blocks that bracket the target density of 1.30 OD.
3. Calculate the "adjusted block" value that would be required to achieve 1.30 OD by applying linear
interpolation between the two bracket blocks' assigned numbers. For example:
Block 10: OD = 1.29
Block 11: OD = 1.36
Block value to achieve 1.30 OD = 10.1 or 10.2
On the front panel, navigate to the Calibration Value menu corresponding to the cassette slot:
Utilities...
Film Calibration...
Cassette n...
Calibration Value...
4. Use the increment and decrement keys on the front panel to enter the adjusted block value
from step 3.
5. To save the entry, press the Enter key.
NOTE: Once saved, this calibration value will apply only to this cassette. Also, this calibration value
will be used regardless of what slot this cassette is inserted into.

Choosing Not to Calibrate a Media Cassette

You can choose not to calibrate a new media cassette.
