Operating The Crxflex; Re-Erasing An Image Plate - GE CRxFlex Operating Manual

Re-erasing an Image Plate

Press the erase button
At the end of a normal digitizing cycle, the CRxFlex returns an erased image plate. However,
in the following cases, you must re-erase the image plate before re-using it in order to
prevent ghost images from interfering with the image of interest:

If the image plate has not been used for more than 48 hours.

If an image plate has been exposed to an exceptionally high X-ray dose.
In this case, deep layers of the image plate may still retain a latent image after standard
erasure. Leave the image plate to rest at least one day before re-erasing it.
To re-erase an image plate:
1 Check that the CRxFlex is ready for operation. The status indicator on the CRxFlex
constantly lights up in green.
2 Press the erase button at the front side. The status indicator is continuously lighting
up in blue. If no cassette with image plate has been inserted after one minute, the
erase mode has to be reactivated by pressing the erase button again.
3 Insert the cassette containing the image plate into the cassette slot as shown below.
Make sure to insert the cassette with the black side to the top and with the shutter
opening mechanism and the locking mechanism inside the CRxFlex. Make sure that
the cassette is firmly pushed to the right side of the slot. Otherwise, the CRxFlex
cannot read the image plate.
As a result, the CRxFlex starts erasing the image plate:

The upper part of the status indicator is continuously lighting up in blue.

The lower part of the status indicator is flashing green.
