Cause: USB drive format or file name mismatch.
Fix:
Between late Q1 and early Q2 of this year, users trying to download the System Software (v72.02 or later) for the iR 2425 encountered several errors:
Important: Unlike consumer printers, Canon imageRUNNER firmware is not always hosted publicly on the general support site. It is often located behind a support login or available via your local Canon authorized dealer. canon ir 2425 firmware download fixed

It’s written in a helpful, tech-support style, suitable for a blog, FAQ, or knowledge base.
Downloading the correct file is only half the battle. Applying the firmware to the iR 2425 requires a specific, error-sensitive procedure. The standard method involves the Canon Service Support Tool (SST) running on a Windows laptop, connected to the printer’s USB port (or via a dedicated service port on the main controller). The steps are unforgiving:
A common mistake is assuming that a successful firmware write means the fix is active. Many fixes require resetting specific counters or performing a calibration routine (like a DC-CON adjustment) to take effect. Skipping these post-update steps leaves the original problem unresolved.

Once access is granted, the next challenge is identifying which version is actually “fixed.” Firmware for the iR 2425 is modular, often consisting of multiple components: the main controller firmware, the boot ROM, the DCON (engine control), and the RCON (operation panel). A release note from Canon will list each component’s version and the specific issues resolved.
A “fixed” download is rarely a single monolithic file. It might be an entire package where the main system firmware is updated from version 55.02 to 55.05, with a patch note stating: “Resolves intermittent jam code 0107 when using A4-R paper from cassette 2.” Before downloading, the technician must verify that the fixed version is newer than what is currently installed (checkable via the device’s counter display screen under “System Information”). Jumping multiple major versions (e.g., from v50 to v60) may require intermediate updates, which the release notes will explicitly warn about. Ignoring this can cause non-bootable conditions.
