SHARP DTE124 Technical Report

Date: Mar. 29, 1994
DUPLICATOR : SD-2060
No. : DTE-124
CHANGE IN THE ADF CONTROL ROM TO IMPROVE THE ORIGINAL COPY SIZE DETECTION AND THE ORIGINAL COPY STOPPING PRECI SIO N .
1.General: The ROM of the PBA control PWB has been changed to improve the RADF original
copy size detection and original copy stopping precision in model SD-2060.
2.Description: 1. Improvement of original copy size detection. (1)The software has been changed so that when the original copy is of a size other
than the standard copy paper sizes an appropriate size of copy paper is automatically selected by the paper size detection function during automatic paper size selection mode operations.
Ex. When a B4 size paper is double folded and set, the length of the paper is
detected as between B4 and B5, and assigned as “special”, and the copy paper size selected when the original copy was set was used. With the change in software described above, B4 is automatically selected.
Ex. If an A4 size paper is aligned with the original copy guide width and B5R size
original copy is selected (Random feed during SDF mode operations), the paper is detected as between A3 and A4, and assigned as “special”, and as in Ex. above, the copy paper size selected with the original copy was set was used. With the change in software described above, A3 is automatically selected.
(Size detection change.)

Prevention of detection errors during when setting standard sized original copies
other than design specifications and during automatic paper size selection mode operations has been carried out. Detection errors which occur when setting the original copies however, occur in spite of specifications.

The original copy sizes detected and selected operation sizes when setting standard sized original copies are shown in the tables below. Those size selections which are shaded are the sizes selected when sizes other than the standard sizes are detected.

Operation detection.
The selections shown in the table above operate for all sizes of set original copies other than design specifications. However, When detection errors occur during operation size detection, copy operations are stopped. (during automatic paper selection mode operations).
