Ricoh Mp 5055 Firmware Update

Ricoh MP 5055 Firmware Update Guide

2. Why Update? (The Changelog Analysis)

For the MP 5055, firmware updates generally fall into three categories:

Step 2: Prepare the USB Drive

1. Insert a FAT32-formatted USB drive into your PC.
2. Create a folder named: romdata (all lowercase, exact name required).
3. Inside romdata, create a subfolder for each module (or copy all .FUN files directly into romdata as per your update method – most new Ricohs read multiple files from romdata).
4. Copy the extracted firmware files (e.g., D1405100H.fun for system) into romdata.
5. Safely eject the USB drive.

Note: For the MP 5055, a single romdata folder containing all module .FUN files is standard. Do not rename the .FUN files. ricoh mp 5055 firmware update

Preparation and Precautions

Before initiating a firmware update, strict preparations must be taken to avoid "bricking" the device (rendering it unusable). Ricoh MP 5055 Firmware Update Guide 2

• Backup Settings: While firmware updates generally retain user settings, it is highly recommended to export the Address Book and configuration settings via the device's Web Image Monitor before proceeding.
• Stable Power: Ensure the device is connected to a stable power source. Do not perform updates during a storm or on a circuit prone to tripping. If the power cuts out during the update, the mainboard may be permanently damaged.
• Verify Model Number: Ensure the firmware is specifically for the MP 5055. Installing firmware intended for the MP 5054 or MP 6055 can damage the machine.
• Stop All Jobs: Ensure no one is printing, scanning, or faxing. The update process will restart the machine, interrupting any active jobs.

Part 7: Best Practices and Maintenance Schedule

To avoid emergencies, adopt a proactive firmware schedule for your Ricoh MP 5055:

• Check quarterly (every 3 months): Visit the Ricoh support site and compare your versions against the latest release notes.
• Defer non-critical updates: If your printer is working perfectly and you don't have security concerns, you can skip minor patches. But always install security updates.
• Batch updates during downtime: Never update a firmware on a Wednesday morning at 9 AM. Schedule it for Friday evening or a scheduled maintenance window.
• Keep a dedicated "Firmware SD Card": Buy a reliable 4GB SD card, label it, and keep it in your IT closet with only Ricoh tools on it.

Remote & Network Updates (For IT Admins)

Ricoh also supports Remote Firmware Update via @Remote (Ricoh’s cloud service) or WIM (Web Image Monitor).

• Via WIM: Log into the printer’s IP address > Device Management > Firmware Update (if enabled). You can point to a local server hosting the .fwu file.
• Via @Remote: This is the gold standard for fleets. The machine phones home, and the update pushes automatically during off-hours.
