A modern office or home workspace is impossible to imagine without convenient peripherals and a compact laser printer The Ricoh SP 150 is a leader here thanks to its reliability. However, out of the box, this device is often configured only for USB operation, which limits portability and printing from multiple devices on the network. Users often encounter difficulties when trying to switch the device to wireless mode, as the procedure requires a strict sequence of steps.
The main difficulty is that this model lacks a full menu screen for entering the router password, so the entire process occurs through software on a computer or smartphone. Wireless connection This requires preliminary driver preparation and an understanding of the communication protocols between the router and printer. In this article, we'll walk you through a detailed procedure that will allow you to forget about wires.
Before you start any manipulations, make sure that your device actually supports wireless communication, as the modification The SP 150w differs from the basic version by the presence of a WiFi module. The presence of an antenna or WiFi icon on the housing provides visual confirmation of this capability. If you attempt to set up a network on a model without a built-in module, the software will simply not detect the hardware.
Equipment preparation and compatibility testing
The first step to successfully integrating a printer into a local network is to thoroughly check the physical condition of the equipment and its compatibility with your infrastructure. Model Ricoh SP 150w works in standard IEEE 802.11b/g/n, which means it supports most modern home routers, but there may be some issues with frequency ranges. It's important to understand that this printer, like many budget office devices, operates exclusively within the frequency range. 2.4 GHz and doesn't see the network 5 GHz.
If your router broadcasts a network with the same name (SSID) for both bands, the printer may attempt to connect to an unsupported frequency or become confused by encryption protocols. In this case, it's recommended to temporarily separate the networks in the router settings or ensure that the device (laptop or phone) connecting to the network is connected. 2.4 GHzAlso, check that AP client isolation, which prevents devices within the network from exchanging data, is not enabled on the router.
To connect, you will need a computer running Windows or macOS, or a smartphone with the app installed. RICOH Smart Device Connector. Make sure the printer is turned on, in ready mode (green indicator), and located within a strong signal range. The distance to the router should not exceed 10-15 meters if there are walls, otherwise the driver installation process may be interrupted while searching for the device.
⚠️ Attention: Make sure MAC address filtering isn't enabled on your router. If it is, you'll need to find the printer's MAC address (usually on a sticker on the back) and whitelist it beforehand; otherwise, the device simply won't receive an IP address.
Particular attention should be paid to the version of the operating system of your computer. Although Ricoh SP 150 is a classic device, new versions Windows 10 and 11 These may require manually selecting a driver from a list or downloading the latest version from the official website, as the OS's built-in drivers sometimes don't work correctly with WiFi functions. Downloading the full driver package before starting setup will save you time and frustration.
Installing drivers and software
The foundation for stable operation of any peripheral is correctly installed software. For the model For the Ricoh SP 150w, it's not recommended to rely on automatic driver installation via Windows Update, as it often installs a basic PCL driver that doesn't include network configuration utilities. You'll need to download the full package. Printer Driver and Utilities from the manufacturer's official website.
The download process should only be done from a trusted source. Go to the Ricoh support page, select your model and operating system. Please note the bit depth of your system (x86 or x64), although modern installers are usually universal. After downloading the archive, be sure to unzip it into a separate folder to avoid path errors when running the executable.
Run the setup file (usually Setup.exe or Install.exe). In the initial window of the installation wizard, you will be asked to select the connection type. At this stage don't choose Select the "Connect via WiFi" option immediately if you haven't yet installed the basic drivers. First, select "USB connection" or "Local connection" so the system recognizes the device and installs the basic command set.
- 🖥️ Run the installer as administrator by right-clicking on the file and selecting the appropriate option.
- 🔌 Connect the printer to your computer via USB cable only after the corresponding prompt appears in the installation window.
- ✅ Accept the license agreement and wait until the files are copied to the system folder.
After successfully installing the basic driver, a new printer will appear in the system. Now you can proceed to changing the connection type. The folder with installed Ricoh utilities often contains a program Device Manager or a similar tool that allows you to switch ports. However, a more reliable method is to use the dedicated WiFi configuration utility included with the device, or re-run the installer and select the option to change the connection type.
Connection method via WPS (Quick Setup)
The fastest way to integrate Ricoh SP 150w in a wireless network is the use of technology WPS (Wi-Fi Protected Setup)This method allows you to transfer network settings (SSID and password) from your router to your printer without having to enter them manually, which is especially convenient given the lack of a keyboard on the device itself. To use this method, your router must support WPS and have a dedicated button.
The process is as follows: Make sure the printer is turned on and ready to use. Locate the button WPS on the router body. Press and hold it for 2-3 seconds until the WPS indicator on the router flashes. You must then activate WPS mode on the printer within 2 minutes.
On the control panel On the Ricoh SP 150w, find the button with an antenna or WiFi icon. Press it until the lights start flashing in a specific pattern (usually a rapidly flashing green light). This indicates that the printer is waiting for a WPS signal. If a connection is not established within two minutes, the lights will return to their original state, and you will have to repeat the procedure.
⚠️ Attention: WPS is considered less secure than manual setup because it uses vulnerable authentication protocols. If you're using the printer on a corporate network with high security requirements, it's better to use manual setup via USB or Smart Device Connector.
A successful connection is confirmed by the printer's WiFi indicator being lit steadily (not blinking). After this, you can remove the USB cable. A computer on the same network should automatically detect the new network device. If this doesn't happen, try adding the printer manually by entering its IP address, which can be found by printing a configuration report (usually by holding the WiFi button or through the utilities menu).
Setting up WiFi Direct for printing from a smartphone
Function WiFi Direct Allows you to connect mobile devices directly to the printer, bypassing your home router. This is ideal for printing photos from your phone or documents from the cloud when your main internet connection is unavailable or overloaded. In this mode The Ricoh SP 150w becomes a mini-router itself, creating its own access point.
To activate this mode, press and hold the WiFi button on the printer's control panel until the indicators enter standby (pairing) mode. This is usually indicated by alternating blinking of the WiFi and Error lights. It's best to check the manual for the exact blinking pattern, as it may vary depending on the firmware revision.
On your smartphone, go to WiFi settings. In the list of available networks, you should see a name starting with RICOH_SP150... or something similar. Click on it. The system will ask for a password. By default, the password is often listed on a sticker on the printer body or in the user manual, or it may be a combination like 12345678.
- 📱 Download the app RICOH Smart Device Connector from Google Play or the App Store for advanced functionality.
- 🔗 Connect your phone to the printer's network and launch the app to scan documents or select a file.
- 🔒 After printing, remember to disable WiFi Direct on your printer to avoid leaving your network open to strangers.
It's important to note that while WiFi Direct is enabled, the printer may not have internet access unless it supports both client and access point modes (which is rare for this model). Therefore, this method is not suitable for printing from the internet (for example, Google Cloud Print); it is intended solely for local data transfer.
What should I do if my phone can't see the printer's network?
Make sure your phone's mobile data (4G/5G) is disabled while searching, as Android may ignore WiFi networks without internet access. Also, try forgetting the network on your phone and then searching for it again.
Manual network setup via USB cable
If automatic methods do not work or your network is hidden (does not broadcast SSID), the only reliable option is manual configuration via USB cable using a utility Wireless LAN Utility. This method provides complete control over settings and allows you to assign a static IP address, which is critical for stable operation in the office.
Connect the printer to your computer via USB. Launch the wireless network configuration utility (included in the full driver package). The program will prompt you to select your network from a list of available ones. Select the desired SSID. If the network is hidden, select "Enter the network name manually" and enter the name exactly, taking care to ensure proper case-invariant compatibility.
Enter your WiFi password. Be careful: when entering the password on your computer keyboard, you may not see the asterisks, so check your keyboard layout. After entering the information, the program will attempt to transfer the configuration to the printer. At this point, the device's indicators will begin to flash rapidly.
After successfully transferring the settings, the utility will prompt you to disconnect the USB cable. Do so. The printer should now connect to the router automatically. To check, print a network configuration page. It will show the IP address assigned by the router. Compare it with your network range.
| Parameter | Default value | Recommended value | Where to change |
|---|---|---|---|
| IP Address Mode | DHCP (Auto) | Static | Web interface / Utility |
| Sleep Mode | 15 min | 3-5 minutes | Driver settings |
| Protocol | Mixed | 802.11n only | Router (Advanced) |
| Security | WPA2-PSK | WPA2/WPA3 | Router |
☑️ Manual setup checklist
Assigning a static IP address
One common problem with network printing is the printer's IP address changing after a reboot. The Windows driver is bound to a specific address, and if it changes, the printer's status will become "Offline." To avoid this, you need to assign static IP address the device itself or reserve an address in the router.
The most reliable way is to use the printer's web interface (if accessible through a browser) or utility Web Image Monitor. Enter the printer's current IP address into the browser's address bar. Go to Network -> TCP/IPHere you will see the current settings.
Select the "Static" mode. You will need to enter:
1. IP Address: for example, 192.168.1.200 (make sure this address is not occupied by another device and is outside the router's DHCP range).
2. Subnet Mask: usually 255.255.255.0.
3. Gateway: the address of your router, for example, 192.168.1.1.
⚠️ Attention: An incorrectly specified gateway will result in the printer being visible only within the local network and unable to send reports or update, if such features are enabled. Carefully check the router address before saving.
After applying the settings, the printer will reboot. You'll need to remove the old printer from Devices and Printers and add the new one, specifying the new static IP address when creating the port (Create new port -> Standard TCP/IP Port). This ensures the computer always connects to the correct address.
Solving common connection problems
Even if all instructions are followed, situations may arise when The Ricoh SP 150w printer is not working properly. Often, the problem lies not with the printer itself, but with Windows power saving settings or antivirus software. If the printer "disappears" from the network, check the power management settings for the USB ports in Device Manager.
Another common problem is a conflict of security protocols. If the router is configured to operate only in wireless mode WPA3The printer's old WiFi module may simply not connect. Try temporarily switching your router to compatibility mode. WPA2/WPA3 Mixed or even purely WPA2 for verification.
If the WiFi indicator is flashing red or orange, this indicates an authentication error. Double-check your password. In some cases, resetting the printer's network settings to factory defaults (usually by holding the WiFi button or using the button combination described in the manual) and repeating the process from scratch can help.
- 🔍 Check if Windows Firewall is blocking the port
9100, used for printing. - 🔄 Reboot your router to clear the ARP table and assign a new IP address.
- 📶 Make sure your WiFi channel is not overloaded by neighbors (use channels 1, 6 or 11).
Finally, the setup Ricoh SP 150 Connecting to WiFi is a process that requires attention to detail, but is quite doable. The key is to use a complete driver package, understand the differences between WiFi modes, and don't be afraid to manually configure IP settings to ensure stability. A properly configured printer will become a discreet yet reliable assistant in your work.
Can the Ricoh SP 150 be connected to a 5GHz network?
No, the SP 150w model is equipped with a module that only operates in the 2.4 GHz band. Connecting to a 5 GHz network is technically impossible.
