17. MAIN PCB ROM HISTORY
A207/A208/A211 Firmware Modification History (Main PCB Copier)
Description of Modification
Initial Production
The Main PCB ROM has been upgraded to meet
Energy Star requirements. This ROM enables
the following:
•
Auto Energy Saver Time Setting (SP5-102)-
The setting for the Auto Energy Saver has
been changed from "1 to 120 minutes" to "1
to 240 minutes".
•
Auto Shut Off Time Setting (SP5-305-001)-
The setting for the Auto Shut Off has been
changed from "1 to 120 minutes" to "1 to 240
minutes".
Corrects the following:
•
No Paper Feed Jam at Duplex Copy: The
start speed of the Transport Motor has been
corrected for paper fed from the Duplex Tray.
If the pressure of the Bottom Plate is
insufficient due to the unstable start speed of
the Transport Motor, the paper in the Duplex
Tray may not be fed.
•
SC721 when setting up the A557: A SC721
may occur when setting up the A557. The
detection time for the SC721 has been
changed from 300 msec to 400 msec to
prevent the SC721 from occurring.
Corrects the following:
•
A SC440 occurs when power is turned on
with the Front Cover opened, then closed
and then actuating the START Key. A
change was made to the Main Motor circuitry
to improve the reliability of the motor, which
caused the ROM software to not recognize
the Main Motor.
