BIOS/Bootloader Corruption Detected

Model-Specific Notes: • T-Series (T1700, T850, T950): Some models have a 'BIOS Recovery' jumper or button on the main PCA. Consult the service manual for its location and procedure. • Z-Series (Z6, Z9+): These often use a more integrated UEFI-style boot. Recovery might involve a specific USB boot key with a recovery image. • PageWide XL: BIOS issues on these high-end devices almost always require a main PCA replacement by a certified technician. Expert Insight: For models with a dedicated BIOS recovery mode, ensure the USB drive is properly formatted (FAT32) and contains the correct BIOS recovery file (often named 'BIOS.bin' or similar). If the printer has a serial console port, connecting via PuTTY or similar software might provide more detailed boot-up messages that can aid in diagnosis before resorting to PCA replacement.
