MINOLTA CO., LTD., SERVICE ENGINEERING DIVISION PAGE NO. : 1/3 SERVICE BULLETIN PROBLEM FUNCTION SAFETY SERVICEABILITY OTHERS MODEL NAME : Di620 OTHERS PERFORMANCE CORRECTION SAFETY REGULATION OTHERS MODEL CODE : 1155 NO. : 028E DATE : 990304 SUBJECT : COUNTERMEASURE FOR BLACK STREAKS WHEN EDH IS USED PROBLEM: There is a possibility that black streaks in the feeding direction may occur on copies when the EDH is being used. CAUSE: Dust sticks to the inner side of the EDH original glass. SOLUTION: To prevent dust from entering, a sponge (01) and polyester film (02) have been newly made. 01 02 EDH Original Glass In connection with this change, the software program for IC26IB (03) on PWB-IB, IC21B (04, 05) and IC70B (06) have been changed to add a new function of "Density (ADF)" to p. 6/6 of the User's Choice screen. (This function is valid only when the EDH is used and not when the original is placed manually.) When Mode 1 is selected, the copier uses a gradation curve that cancels out low image density areas, which effectively prevents black streaks from occurring even when tiny dust particles stick to the EDH original glass. Select the appropriate mode according to the need as detailed below: 1) Using ordinary originals (such as printouts from a word processor): Select mode 1. 2) To ensure better reproduction of faint originals: Select mode 2. 04 , 05 03 PCJ-242iA PRINTED IN JAPAN S/B NO. : 1155-028E PAGE NO. : 2/3 03 1155-IC26IB 1155-IC26IB 6607-48 6607-49 23G022-00 23G028-00 04 1155-IC21 1155-IC21 6620-03 6620-04 80G006-00
