The software communicates with the printer via USB, parallel port, or network connection (usually on a closed service LAN). It operates in a special “download mode” that bypasses normal user restrictions.
I should first note that Canon SST is proprietary service software intended for authorized Canon technicians. It’s used to flash firmware, reset counters, perform adjustments, and troubleshoot certain Canon copiers/printers. Unauthorized distribution, modification, or use of such tools typically violates Canon’s end-user license and may void warranties or cause device damage.
The Service Support Tool acts as the primary bridge between a technician's computer and the Canon device's controller. It is not a standard print driver, but rather a low-level system utility.
Run setup.exe or the designated installation application, making sure any corresponding USB connection to a printer is disconnected beforehand. 2. Firmware Registration
Connect the Canon device to the PC using a USB cable, a cross-over Ethernet cable, or a specialized USB-Parallel cable depending on the model.
Added support for downloading and uploading multiple firmware files and sublog reports simultaneously.
