Model Ricoh SP 150suw — a compact laser printer ideal for home use or a small office. Its key advantage is its wireless connectivity, allowing you to print from a laptop, smartphone, or tablet without the hassle of cables. However, setting up Wi-Fi on this device can often be confusing, especially if you've previously only used wired printers.
In this article we will look at all stages of connection — from preparing your equipment to troubleshooting common errors. You'll learn how to correctly enter network settings, where to find your printer's MAC address, and what to do if your device isn't visible in the list of available devices. We'll also give you tips on optimizing your connection for stable and fast Wi-Fi printing.
Preparing for setup: what you'll need
Before you begin the connection, make sure you have everything you need. Without these components, the process may be delayed or even fail.
- 📄 Printer manual — it shows the factory Wi-Fi settings (if the printer is new) and the location of the buttons.
- 🔌 Power supply and cable — the printer must be connected to the network throughout the entire setup process.
- 📶 A working Wi-Fi router with known network names (
SSID) and a password. Make sure your router isn't blocking new devices. - 💻 Computer, laptop or smartphone — to enter settings and check the connection.
If the printer has been used before, Be sure to reset your network settingsTo do this, hold down the button Wi-Fi on the control panel for 5-7 seconds until the indicator light starts flashing orange. This will reset the wireless module to its factory settings.
⚠️ Attention: If your router operates in the range5 GHz, printer Ricoh SP 150suw may not see it. This model only supports2.4 GHzCheck your router settings and enable compatible mode if necessary.
How to set up Wi-Fi on the Ricoh SP 150suw
The manufacturer offers three main methods for connecting the printer to a wireless network. The choice depends on your preferences and available equipment:
- Via WPS (Wi-Fi Protected Setup) — the fastest way if your router supports this function.
- Using the printer control panel — manual input
SSIDand password. - Through the utility Ricoh Smart Device Connector - convenient for setting up from a smartphone.
Let's look at each of them in detail. Let's start with the simplest one - connecting via WPS.
Method 1: Connecting via WPS
This method takes less than a minute, but only works if the router has the function activated. WPS (usually a button with this name is located on the back panel).
Make sure your router supports WPS|Turn on the printer and wait until it's ready|Place the printer close to the router (no further than 1–2 meters)|Prepare the WPS button on the router
-->
- Click the button
Wi-Fion the printer and hold it for 3 seconds until the indicator starts flashing quickly. - For 2 minutes press the button
WPSon the router. - Wait until the Wi-Fi light on the printer turns on green (this will take 10-30 seconds).
If the indicator continues to flash or remains orange, repeat the process. The router may not have had time to process the request.
⚠️ Note: Some ISPs disable WPS by default for security reasons. If the button doesn't work, check your router settings in the "Settings" section. Wireless Network → WPS.
Method 2: Manually entering network parameters
If WPS is unavailable or doesn't work, you'll have to enter the settings manually. To do this:
- Click the button
Menuon the printer. - Go to the section
Network → Wireless LAN → Setup Wizard. - Select your network from the list (or enter
SSIDmanually if it is not in the list). - Enter your Wi-Fi password. Use the arrow keys to select characters.
- Confirm your input and wait for the connection.
The process may take up to 1-2 minutes. If the printer displays an error Connection Failed, check:
- 🔄 The password you entered is correct (case sensitive!).
- 📡 Signal level - the printer must be in a strong reception area.
- 🔒 Encryption type — Ricoh SP 150suw supports
WPA2-PSK (AES)If you have a different standard, change it in your router settings.
Method 3: Setup via Smartphone (Ricoh Smart Device Connector)
This method requires an app. Ricoh Smart Device Connector (available for Android And iOS). It allows you to not only connect the printer to Wi-Fi, but also manage printing from mobile devices.
- Install the app from App Store or Google Play.
- Turn on
Bluetoothon a smartphone and printer (buttonWi-Fiheld for 5 seconds until it flashes blue). - In the application, select
Add a device → Ricoh SP 150suw. - Follow the on-screen instructions to connect to Wi-Fi.
The advantage of this method is that it automatically detects available networks and allows you to enter the password using your smartphone's keyboard (which is more convenient than using printer buttons).
Checking the connection and troubleshooting
After setup, you need to ensure that the printer has successfully connected to the network. To do this:
- Click the button
Wi-Fion the printer - the indicator should be on green (if it blinks orange, the connection is unstable). - Print it out network report: hold down the button
Menufor 3 seconds →Network → Print Report. - In the report, check the lines:
Wireless LAN: ConnectedIP Address(must be in the format192.168.x.xor10.x.x.x).
If your printer doesn't print over Wi-Fi, use the table of typical errors:
| Symptom | Possible cause | Solution |
|---|---|---|
| The Wi-Fi indicator is blinking orange | Weak signal or incorrect password | Move the printer closer to the router or check the password |
| The printer is not visible in the list of devices. | The protocol is disabled mDNS (Bonjour) |
Turn on Bonjour in the router settings or use the printer's IP address |
| Printing is very slow. | Slow connection speed or network congestion | Switch the router to a channel 2.4 GHz with less interference |
Error Offline in the driver |
The printer's IP address has changed | Set up a static IP address on your router or update the driver. |
⚠️ Note: If after several attempts the printer still does not connect, try temporarily disconnecting it firewall on your computer or antivirus - they can block network discovery of the device.
What should I do if my printer is connected to Wi-Fi but won't print?
If the indicator light is green but printing tasks are not performed, check:
1. Is the printer driver installed on your computer (download from the [official Ricoh website](https://support.ricoh.com)).
2. Is the printer in "Offline" mode (in Windows: Control Panel → Devices and Printers → Right-click the printer → Set as default).
3. Does the router block the protocol? LPD (port 515), which is used for printing.
Optimizing your Wi-Fi connection for stable printing
Even if the printer is connected, problems may arise over time, including disconnected connections, slow printing, or errors. To avoid these issues, follow these tips:
- 📶 Printer location — place it at a distance of no more than 5–7 meters from the router, avoiding obstacles (walls, metal objects).
- 🔄 Wi-Fi channel - in the router settings, select the least loaded channel in the range
2.4 GHz(for example, 1, 6 or 11). - 🔒 Encryption type - use
WPA2-PSK (AES), becauseTKIPorWEPmay cause compatibility issues. - 🖨️ Static IP — assign a fixed IP address to the printer in the router settings (based on the MAC address) to avoid conflicts.
If you have a lot of devices on your network, consider creating guest network Specifically for the printer. This will reduce the load on the main channel and improve stability.
Setting up printing from different devices
Once your printer is successfully connected to Wi-Fi, you need to add it to the devices you plan to print from. Let's look at the process for the most popular platforms.

Add device → Add manually. - Select
Add a printer by TCP/IP addressand enter the printer IP (indicated in the network report). - Install the driver from the official website Ricoh (if Windows doesn't find it automatically).
macOS
On a Mac, the printer is usually detected automatically by BonjourIf this does not happen:
- Open
System Preferences → Printers & Scanners. - Click
+ → Add printer. - Select from the list Ricoh SP 150suw or enter its IP address.
- Select driver
AirPrintor download the official one from the Ricoh website.
