Download Service Tool V3400 Printer Canon New! Jun 2026

: V3400 is for older models. Using it on newer printers (like the G-series or newer TS-series) can permanently lock the service mode , requiring a physical motherboard chip replacement.

Modern Canon printers (e.g., PIXMA TS/GM/GX series, MAXIFY) store critical parameters—such as ink absorber counter, head ID, and region settings—in a serial EEPROM or NAND flash. When a firmware update fails or the main controller becomes corrupted, the printer enters a “dead” state (no response, blinking lights). The V3400 tool bypasses the normal bootloader to perform a forced flash rewrite via service mode. Download Service Tool V3400 Printer Canon
