Retrofit Information
Because of software changes, the ROM has been changed for the A076/A077/A078
copiers. Because of the part number change for the ROM, the part number for the main
board also has been changed. All changes are in effect from the first mass production.
The changes are listed below.
1. Main Board #A0775101
2. Main Board #A0765101
3. ROM #A0775104
Details of software changes
1. How to reset "J1" indicator
The J1 indicator is used for paper misfeed and paper end. The indicator can now be reset
two ways: by opening and closing the front cover, or by opening and closing the paper
tray. (Previously, opening and closing the paper tray had no effect.)
2. The VL correction factor is newly added to the exposure lamp voltage control. (Refer to
page 2 - 19 of the service manual.)
VL Correction Factor
The light intensity may decrease because of dust accumulated on the optics parts. The
exposure lamp data is increased by one (1) every 4,000 copies (factory setting) to
compensate for this . The VL correction is applied until the exposure lamp data (SP51)
rearches its maximum of 145. The following SP modes for the VL correction are newly
added:
Mode No.
81 VL Correction
Interval
95 VL Correction
