PT-R4300 USERS MANUAL

7-18

Ex81D : Temperature of environment rises. Lower temperature of the

environment.

This warning message appears when the ambient temperature exceeds 28˚C.
Lower the ambient temperature.

Ex81E : Temperature of environment lowers. Increase temperature of

the environment.

This warning message appears when the ambient temperature is less than 17˚C.
Raise the ambient temperature.

Ex81F : Sensor for temperature of environment has not been connected.

This message is displayed if communication with the sensor for measuring the
environment temperature fails twice.

Ex820 : Trail clamps are nearing the end of its usable life. Please

contact our office or agency and ask to replace them.

If this message appears please contact a Dainippon Screen office or agent and
request a trail clamp replacement.

Ex821 : The clamps have been used for more than the endurance time.

Please contact our office or agency and ask to replace them.

This message will appear if you did not replace the trail clamp after the message
“Ex820: Trail clamps are nearing the end of its usable life...” appeared and the
loading/ejecting process was carried out another 2000 times. If this message
appears please quickly contact a Dainippon Screen office or agent and request a
trail clamp replacement.

Ex824 : Calibration must be done because there is some LD which

doesn’t reach the target power. But, LD calibration can not
processed because temperature of LD block is too low.

When laser intensity is measured periodically, this type of error will occur when
calibration could not proceed because the temperature inside the machine was
too low. This is despite the fact that calibration was determined as necessary
after finding a laser that did not reach the specified intensity.
If this error occurs, raise the working environment temperature and perform laser
calibration from the user maintenance screen.
If you cancel this error you can expose only 23 plates after which the same error
will occur when exposing the 24th plate. Be aware that there could be
unevenness in image quality until calibration is performed.

Ex82A : Since the light intensity of laser diodes is detected as having

deviated more than 5% from the specified value, the equipment
executes the calibration.

This warning message is displayed if automatic calibration was executed as a
result of detection of laser intensity deviation during the laser measurement that
occurs every 16 plates. Carry out a check of the previously exposed plate in
accordance with the explanation in “If a warning message is displayed during
automatic calibration” under Chapter 5 “17. Calibration Information”. After
doing so, please perform laser calibration in the user maintenance screen.

ExEF5 : LD calibration can not processed because temperature of LD

block is too low.

This message is displayed if the internal temperature of the PT-R is so low
(below 20˚C) that laser calibration cannot be performed.
