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.
As of 2026, Canon has quietly improved its download servers (CDN), but isolated issues remain due to browser quirks and USB incompatibility. The phrase “firmware download fixed” often reflects a user-side correction — proper USB prep, checksum validation, or using a download manager — rather than a server-side fix from Canon.
However, for the latest official patched firmware (e.g., version 90.02.01 which resolves scan-to-email TLS 1.3 errors), the download process is now more reliable than in 2024.
Important: The correct file name format for iR 2425 is usually
iR2425_Vxx.xx.xx.zip. Size is around 150–250 MB.
