ISW WHAT'S ISW? ISW (In-System Writer) is a process of updating the control programs stored in flash ROM mounted on various control boards in a Minolta digital copier without isolating the boards from the copier. Running ISW enables you to upgrade control programs without replacing the boards and maintain the boards during their replacement. Tool available for running ISW include ISW Trns (PC software), which connects a personal computer (PC) to the digital copier.
ISW SETUP [1] ISW-compatible boards This machine allows ROM data residing on the following boards to be updated via ISW: • Image control board • Printer control board • Finisher control board [2] Data flow PC Image control board Printer control board Finisher control board Important Note: The availability of the image control program is prerequisite to updating on other boards. [3] Prepare the copier to start an ISW transfer 1. Transfer modes The copier supports two transfer modes as described below.
ISW [4] Preparing the copier to transfer Start the copier with 25 mode enabled to put the copier into ISW transfer wait state. Step 1 Procedure Enter 25 mode. [Memory setting mode menu Screen] 2 Press " 11 ISW". [ISW mode menu Screen] Select the control board on which to update ROM data. 3 [ISW mode Screen] The Start 4 key appears, indicating the copiers readiness to launch an ISW transfer. Follow operating instructions in Minolta ISW (In-System Writer) Service Hand book.
ISW [6] Rewriting procedure after an error interruption If errors occur while writing ROM data, it is written the same way as explained in "Writing ROM data newly" in "[3]2. Instances of ISW transfer". • Image control program The timer LED (orange) flashes. {Nothing will appear on the operation LCD because the image control board controls the entire unit.} Retry ISW after turning the main switch OFF, then ON. • Other control programs Relaunch the 25 mode to retry ISW.
