SHARP CX139R Technical Report

COLOR IMAGE SCANNER : JX-610

PARTS ADDITION/ELIMINATION

A section of the explanation given in Technical Report no. CX-139, issued on September
10, 1993 was unclear and difficult to understand. This revised version of the technical
report is therefore being issued, and we would like to ask that it be used to replace the
first version.

Date: Mar. 3, 1994

REVISED

No. : CX-139 (R)

1. ROM changes
