5. Service Calls
WARNING
If an (A) or (B) service call error occurs you must call a Dainippon
Screen office or agent without fail. Wait for help or proceed with the
error recovery procedure in accordance with the instructions you are
given by the service technician.
There are two types of service calls, (A) and (B), depending on the nature of the
error. They are defined as follows.
(A): This type of error involves the rear edge clamp. This type of error cannot be
cleared without the help of a certified Dainippon Screen service technician. After
such an error even power switch operation does not work. Please call a
Dainippon Screen office or agent as soon as possible.
(B): This type of error occurs during plate transfer (during drum winding, etc.) and
cannot be cleared automatically. However, if the plate that caused the error is
removed from the PT-R, it may be possible to recover from this error after
turning the power off and on. For this type of error be sure to call a Dainippon
Screen office or agent and proceed with the error recovery procedure only after
receiving instructions from a service technician.
CAUTION
!
Never remove a plate that is wound on the drum (when the rear edge clamp
is attached to the plate). This could permanently damage to the PT-R.
Example: If there is a plate wound on the drum when an error, the type of
which cannot be recovered from automatically, occurs during
punching of the next plate, initialization begins after turning the
power off and on if the plate is removed. The plate that was
being wound on the drum is then automatically discharged.
NOTE
The PT-R is designed not to initialize when power is turned off and on after
appearance of service call screens (A) or (B) (error recovery not attempted).
