Service Support Tool (SST) v4.32Ey-supports new models and the bugs have been corrected, it can be
updated anytime. Thus, it is strongly recommended for all SST users to use the latest version. For
exporting to USB memory for upgrade, be sure to use v4.04 or later. For exporting to USB memory for
upgrade using the SST of old versions, there is concern that the incorrect firmware is exported, and 2-line
G3 Fax board cannot work as a result. Due to the G3 Fax modem chip change, the G3 Fax firmware for
Color imageRUNNER C3380/ Color imageRUNNER C5180 series is divided into 2 categories: old
modem chip and new modem chip. Those chips are incompatible; thus, if they are written incorrectly, a
fax function failure will occur. The difference between the 2 chips is only on the version number of the
firmware. (For the old chip, it is from v80-xx onward, and the new one is v01xx to v39xx and auto
distinction is not available.) In the current SST specification, the G3 Fax firmware of the old chip with
escalating version number is written in the USB memory, and if it is connected to the main body of the
new chip, only the version number is compared; hence, it will be incorrectly judged as an upgrade, and a
problem will occur.
Hence, on the SST v4.xx or later, this specification has been changed, and the G3 Fax firmware is
excluded as an export target to USB memory. To upgrade the G3 Fax firmware, it is necessary to do it by
using the Service Support Tool (SST) instead of USB memory.
Assist Mode in Service Support Tool v4.22Et or higher has an automatic G3 Fax firmware select function
where the previous SST v4.11Er requires manual selection.
