When the admissibility of other evidence of contents of writings, recordings or photographs under ORS 40.550 to 40.585 depends upon the fulfillment of a condition of fact, the question whether the condition has been fulfilled is ordinarily for the court to determine in accordance with ORS 40.030. However, the issue is for the trier of fact to determine as in the case of other issues of fact when the issue raised is:
(1) Whether the asserted writing ever existed;
(2) Whether another writing, recording or photograph produced at the trial is the original; or
(3) Whether the other evidence of contents correctly reflects the contents.
