Ex814 : Current offset of printing machine settings cause image to
extend off plate
This message appears if the image size specified by the host computer is within
the allowable exposure area, but the image extends outside of the allowable
exposure area because of the positioning settings in the secondary and primary
scanning directions set for the printing machine information (image positioning
fine adjustment). Confirm the image positioning settings.
NOTE
The allowable exposure area is the maximum plate size of 830
×
660 mm plus 9
mm on each the top, bottom, left, and right.
Ex816 : Some LD is nearing the end of its usable life. Contact our office
or agency and ask to replace them.
This message is displayed if a LD (laser diode) nearing the end of its usable life
is detected when calibration is performed. (refer to “How calibration is
performed” on page 5-53) Even if this message is displayed, the image quality
will not be affected. However, a channel is nearing life-over, so contact a
Dainippon Screen sales office or agency and request for the replacement of the
laser diode.
Once this message is displayed, the same message will be displayed every time
the PT-R is turned on until you have the laser diode replaced and perform
calibration.
Ex81A : Some LD cannot be calibrated to target power. Contact our
office or agency and ask to replace them.
This warning message appears when a LD (laser diode) could not be calibrated
to the set laser power and thus was calibrated to a lowered target power (refer to
“How calibration is performed” on page 5-53). The image quality is not affected
when this message appears. However, as there is a channel nearing life-over,
please contact a Dainippon Screen sales office or agent to have the laser diode
replaced.
Ex81B : Some LD cannot be calibrated to target power. Contact our
office or agency and ask to replace them.
This warning message appears when there is a LD (laser diode) that cannot be
calibrated even when the target power is lowered and thus the laser is calibrated
to use only half of the 32 channels (16 channels) for exposure (refer to “How
calibration is performed” on page 5-53). The image quality is not affected when
this message appears; however, the time required for exposure will double. As
there is channel that has reached life-over and can no longer be used, please
contact a Dainippon Screen sales office or agent to have the laser diode
replaced.
Ex81C : Some LD cannot be calibrated to target power. Contact our
office or agency and ask to replace them.
This error occurs when exposure is not possible at the LD (laser power) because
there was an attempt to increase the laser power setting following calibration to a
lowered target power due to the presence of a laser diode that could not be
calibrated to the original set laser power (refer to “How calibration is performed”
on page 5-53). If this error occurs, perform laser calibration in user maintenance.
