Use a half-tone document and make a 100% copy on B4 or 8 1/2" x 14" paper in the half tone mode.
Make copies at the max. enlargement ratio and the min. enlargement ratio.

Check the uniformity.

Measure the distances between the copy image lead edge and the copy paper lead edge of the max. enlargement copy and the min. enlargement copy, and compare the two.

Is the uniformity OK ?

NO

Change the installing position of the exposure adjustment plate to adjust the uniformity. 0 ± 1.0 mm ?
NO

Change the Sim50-1 set value A so that the difference is within the specified range.

YES Put the scale to the document reference plate and set in the paper transport direction.

Measure the distances between the copy image lead edge and the copy paper lead edge of the max. enlargement copy and the min. enlargement copy, and compare the two.

Measure the distance between the copy image lead edge and the paper lead edge of each copy. L1 = Distance in the max. enlargem ent ratio Distance in the min. reduction L2 = ratio

Measure the distance (L3) between the copy image lead edge and the copy paper lead edge. 0 ± 1.0 mm ? Calculate the Sim50-1 set value from the following formula. C8 = 8.0906 x L3 NO

Change the Sim50-1 set value C so that the difference is within the specified range.
