Ricoh Printer Security Checklist 2025: Default Passwords, Firmware, and Buying a UV, DTF, or Sublimation Printer

I'm an office administrator for a 240-person logistics company with locations in Chicago, Rotterdam, and Manila. I handle equipment purchasing—roughly $180,000 a year across 14 vendors—and I report to operations and finance. I'm not a security researcher. I'm just the person who buys the printers and, occasionally, pays for my own assumptions.

A few weeks ago, I was reading through a printer security news roundup. The Ricoh printer security news section was short, but it used the phrase 'default credentials.' I thought, 'We're fine. We use good passwords.' Then our managed service provider sent me a screenshot during a routine audit. The admin password on our Ricoh MFP was still the default. I had been telling myself it wasn't set that way. It was.

That's the moment I built a checklist. It's not magic. It's six steps that take maybe an afternoon. If you're an office manager, an ops lead, or the 'unofficial IT person' at a mid-sized company, this is for you. It also applies if you're looking at a UV printer in the Philippines, a DTF powder station, or a cheap sublimation printer in 2025.

Why printers are a weak spot

Printers are embedded computers. They have hard drives, network stacks, and web interfaces. But unlike laptops, they are often forgotten once installed. The default password for a Ricoh printer is not secret—it's in the manual. The same is true for other brands. If you never changed it, a person on your network doesn't need a hack; they just need a web browser.

When I see printer security news in 2025, it's usually not a single dramatic breach. It's cumulative: default passwords, unpatched firmware, open scan-to-email, and a printer that has been broadcasting its presence for years. The fix is not a $10,000 firewall. The fix is a checklist.

The Six-Step Checklist

Step 1: Inventory every networked and USB printer

Before you change anything, you need to know what's on your network. I called it a printer inventory, but it's really device inventory. Walk your office or use a network scan and confirm:

• IP address and location
• Model and firmware version
• Connection type: ethernet, Wi-Fi, or USB-to-PC
• Whether scan-to-email or cloud services are enabled

When we did this in 2024, we found three devices nobody remembered installing, including an older wide-format printer connected to a manager's desk. That one was a network hygiene problem. But at least we found it.

Write it down. You can't fix what you don't know exists.

Step 2: Change the default password for Ricoh printer models—and every other printer

If you take one action from this article, do this.

For most Ricoh MFPs, log in to Web Image Monitor with the administrator account. Go to Device Management, then Configuration. Under Administrator Settings, change the authentication password. On many Ricoh models, the factory default is blank or admin. Newer units may have a unique administrator code on a label. The exact default doesn't matter—what matters is that it's publicly documented.

Use a passphrase, not Admin123 or password. I use a sentence I can remember and a password manager. Don't use the same password for the admin account and the setup account. Bad idea.

And if you're thinking 'my office is small, nobody would try,' I had the same thought. That's how the audit screenshot came back with the default login. Five minutes of prevention saved us from having to explain something much worse.

Step 3: Check for firmware updates and security patches

As of January 2025, Ricoh has published multiple security advisories for its printers. The best way to reduce your risk is to set firmware updates on a schedule. Some devices can check automatically via Web Image Monitor or the operator panel. If you're not sure, ask your service provider or set a quarterly calendar reminder.

This is the least exciting step, but also the one that's most likely to prevent a real incident. A printer with outdated firmware is the equivalent of a laptop that hasn't been updated in years. It might still work great, but it's a liability.

Take this with a grain of salt: I've seen automatic updates on a printer that didn't actually run. Verify the firmware version after the update. It's one of those trust, but verify moments.

Step 4: Disable unused protocols and change the boring ones

This is the step everyone ignores because it sounds technical. I avoided it for months. Then I realized I didn't need to understand every acronym. But I do not mean you need to become a network engineer. You just need to ask your managed service provider which protocols are actually being used.

If a printer is running Telnet, FTP, SNMP v1/v2, or raw port 9100, and it's not necessary, disable it. If you use monitoring, use SNMP v3 instead of the older versions. For scan-to-folder, use secure FTP or SMB with proper authentication. If you still need older protocols for an ancient copier, put it on a separate VLAN and limit access.

What I found: one Ricoh MFP had Telnet enabled because a previous vendor used it for configuration more than three years earlier. No one was using Telnet now. It was just open. Disabling it took 30 seconds and reduced the attack surface. That's the kind of cheap win you want.

Step 5: Lock down the print queue and hard drive

Most businesses focus on network access, but a printer is also a storage device. Every scan and every print job can leave data on the internal hard drive. If a printer has Secure Print or pull printing, use it. With pull printing, the job is held on the server or printer until the person walks up and enters a PIN. That way, sensitive documents don't sit in the output tray waiting for the wrong person.

Also, when you return or dispose of a printer, wipe the hard drive. Some Ricoh MFPs have a data erase or storage overwrite function. Use it. I don't remember how many used printers I've seen sold without a hard drive wipe. Not ideal. But if you're the buyer, it's something to ask for.

Step 6: Apply the same checklist to UV, DTF, and sublimation printers

This section started because, in late 2024, we began researching a UV printer. Our product labeling team wanted to do in-house labels, and a supplier in the Philippines had some of the lowest quotes. I was excited about the print quality. Then I asked about the admin password and firmware updates, and the sales rep looked at me like I'd asked if the printer was safe to use in a bathtub.

If you're searching for a UV printer Philippines deal, don't assume budget equipment has the same security defaults as enterprise gear. Ask specifically:

• What is the default admin login, and can I change it before the printer goes on the network?
• Does this model have firmware updates, and how are they delivered?
• Can the printer be isolated on a VLAN or connected via USB only?
• Is there a support contract with someone local who can factory-reset or service the device?

For DTF printer powder: yes, it's messy, but the actual printer is still a computer. A DTF printer might be a converted Epson or a dedicated DTF unit, and it still has an admin account. Keep it on a separate Wi-Fi network if you can. Same for a sublimation setup. I'm not going to tell you how to handle adhesive powder—I'll leave that to the people who do it daily. I am telling you to change the password before you print your first transfer.

And if you're looking for the best cheap sublimation printer 2025, as of January 2025 the usual budget candidate is still the Epson EcoTank ET-2800 series—at least in the US. It's often converted to sublimation ink because the refillable tank makes ink costs manageable. I had two days to pick one for a product test pop-up, and I went with it because our local supplier had stock. In hindsight, I should have ordered a second one just for regular ink. With the deadline, I made the call with the information I had. The point: whether it's a Ricoh production press or a $300 converted EcoTank, the security basics are the same.

Common mistakes to avoid

Here are the three mistakes I'd warn an assistant about if I were training them today.

Mistake 1: Thinking 'factory default' means 'set up for me.' It means set up to get you in and immediately changed.

Mistake 2: Setting admin passwords to Password1 or Admin2025. Attackers know the list. Use a passphrase. The longer, the better. If you need to write it down, use a password manager, not a sticky note on the MFP.

Mistake 3: Treating the printer like an island. A printer that can scan to email is connected to your email system. A printer with cloud services is connected to the internet. A printer with a hard drive is connected to your data. It's not an island.

The bottom line

The Ricoh printer security news that finally got my attention wasn't a zero-day exploit. It was the fact that the default admin password on our own device was still active. I knew better, and yet I didn't check.

Spend one afternoon on this checklist. Five minutes of verification beats five days of cleanup. For me, it's the cheapest insurance I buy.
