ADJ 4.1.6 Installing a Firmware Upgrade in the
Scanner
Purpose
The purpose of this procedure is to allow the installation of new firmware
code into the Flash ROM memory of the Scanner.
Procedure
Note: This procedure uses the SCSI 7356 software as haded onto a
Personal Workstation or other personal computer directly connected to
the Scanner. If the controlling system has its own built-in diagnostics,
refer to the service manual for the controlling system.
Check
1. Start the diagnostic software, using the procedure appropriate for
the system to which the Scanner is connected.
Refer to Section 6.
2. Select Download Code from the Service Diagnostics menu.
3. Install the software upgrade disk in the floppy disk drive of the
controlling computer.
4. (Figure 1) Select the Scanner Firmware button.
• The diagnostic software polls the Scanner and reads the software
upgrade disk. The software versions are displayed in the On
Diskette and the Installed boxes.
• If the versions are the same, select the Exit button.
• If the On Diskette version is more recent, perform the installation.
Installation
1. Ensure that steps 1 - 4 of the Check procedure are complete.
Do not continue if a version number is not shown in the
Installed box.
Once you select the Begin button, do not allow the
process to be interrupted. Any interruption may cause
corruption of the Flash ROM. The Control PWB in the
Scanner will then be unable to communicate, requiring
