Erase PLATE
11–56
[5] When the End of Scan is reached, the MSC sends a status message to the
MCPU.
[6] The MSC turns the L2 SOLENOID off which disengages the NOSEPIECE.
[7] The NOSEPIECE CLEAR SENSOR, S6, detects that the NOSEPIECE is in
the Clear position. It is now retracted so that the EXTRACTION BAR can
pass on its way back up to Home position.
[8] The MCPU turns the PMTs and the GALVO off.
[9] The MSC closes the LASER SHUTTER.
[10] The MCPU sends a Scan End message to the INTERNAL PC. The Timed
Progress Bar, however, will display until the image is completely transferred
to the PC. This event may actually occur after the PLATE has been erased
and reinserted into the CASSETTE and the CASSETTE removed from the
CR 800.
[1] The MCPU sends an Erase Plate command to the MSC which tells the
SLOW SCAN to begin the Erase.
[2] The SLOW SCAN MOTOR starts and moves the PLATE into the Erase
position based on the encoder counts.
[3] The PLATE is then moved down and additional 1 to 2 inches to center the
PLATE in front of the ERASE LAMPS.
[4] The SLOW SCAN MOTOR stops and waits for a response from the MCPU
to erase the PLATE.
[5] The MCPU issues the Erase command along with the erase time to the
MSC, which turns on the ERASE LAMPS.
[6] The ERASE LAMPS stay on from 2 - 10 seconds to expose the PLATE and
remove the image.
Note
The length of time the ERASE LAMPS stay on is determined by the highest pixel
code value of the image being erased. If one LAMP is not functioning, the time
doubles. if more than one LAMP is not functioning, a message is displayed on the
TOUCH SCREEN.
[7] When the Erase is completed, the MSC sends the status to the MCPU.
