The Epson EcoTank ET-16650 is an all-in-one printer designed for demanding home-office and business workflows. Its wide-format capabilities make it useful for documents such as large spreadsheets, business forms, presentations, and other materials that require flexible paper handling.
To use the printer effectively from a computer, you need compatible printer software. The correct driver helps applications communicate with the printer and exposes supported options for paper selection, print quality, orientation, and other settings.
Downloading a driver is only one part of the process. You also need to confirm that the software matches your operating system, configure the printer correctly, and check that the available settings match your intended printing task.
This guide focuses on the practical considerations of installing ET-16650 software, particularly for users who work with different paper sizes, multiple paper sources, and large office documents.
1. Identify the Exact Printer Model
Start by confirming that your device is an Epson EcoTank ET-16650. Similar-looking model numbers may use different software packages.
Follow these steps:
Examine the model label on the printer.
Confirm that the model number is ET-16650.
Turn on the printer and check the display.
Look for any existing error messages.
Determine whether the printer is already connected to a computer or office network.
Note whether you need printing only or both printing and scanning.
This information will help you select the appropriate software and avoid installing a package intended for another printer.
2. Check Your Computer Before Downloading
Before downloading the driver, identify your operating system and confirm that your computer can install software.
For Windows users
Open Settings, select System, and choose About. Record your Windows version and system type.
Use this information when selecting a compatible package. If you use a managed office computer, you may need administrator permission to install printer software.
For macOS users
Open the Apple menu and select About This Mac. Note the installed macOS version.
Check the software requirements listed for the ET-16650. Do not assume that every driver package supports every macOS release.
Prepare your computer
Before installation, close unnecessary applications and ensure that you have a reliable internet connection if the installer needs to download additional components. Also make sure you know whether you plan to connect the printer through USB or a network.
3. Locate the Correct ET-16650 Software
Use Epson's official support resources to locate the available software for your exact model.
Open a browser.
Navigate to Epson's official support section.
Search for EcoTank ET-16650.
Confirm the model displayed on the product page.
Open the drivers or downloads section.
Select your operating system if prompted.
Read the descriptions of the available packages.
Identify the recommended printer driver or installation utility.
Check whether scanner software is listed separately.
Review the compatibility requirements before downloading.
Depending on your operating system and the packages currently offered, the available downloads may include a printer driver, scanning software, a combined installer, or maintenance utilities.
Choose the components that match your needs. Avoid downloading every listed utility without checking its purpose.
4. Download the Driver Safely
Once you have identified the compatible package, download it to your computer.
Select the required package from the ET-16650 support page.
Check its name and description.
Confirm that the operating system is correct.
Select the download option.
Wait until the download finishes.
Open your Downloads folder.
Locate the downloaded installer.
Keep the original filename so that you can identify it later.
Avoid using unverified driver websites. An unofficial installer may be outdated, incompatible, or contain unwanted software.
If the download fails, check your internet connection, available disk space, and browser download settings before trying again.
5. Install the ET-16650 Driver on Windows
After the download finishes, install the package by following its instructions.
Turn on the ET-16650.
Save any open documents.
Locate the downloaded installer.
Open the file.
Approve the Windows permission prompt if you trust the source.
Read the installation instructions.
Accept the applicable terms if you agree.
Select the connection method when prompted.
Follow the instructions to detect or add the printer.
Wait for the installation to finish.
Some packages install a single driver, while others include several software components. The available screens and steps may differ.
Once installation is complete, open Windows printer settings and confirm that the ET-16650 appears in the device list. If the printer does not appear, check the connection and try adding it through the operating system's printer settings.
6. Install Compatible Software on macOS
Mac users should select a package that supports both the ET-16650 and their installed macOS version.
Open Epson's official support resources.
Search for the ET-16650.
Select your macOS version if required.
Review the available printer and scanner packages.
Download the compatible software.
Open the downloaded installer or package.
Follow the installation instructions.
Connect the printer using a supported connection method.
Open System Settings.
Select Printers & Scanners.
Add the ET-16650 if it is not listed.
Complete the setup.
Some macOS versions may provide basic printing support automatically. Additional Epson software may be necessary for scanning or specific printer functions.
After installation, check that the printer is available and that the selected driver provides the settings required for your work.
7. Configure Large Paper Sizes Correctly
The ET-16650 is designed for wide-format printing, so paper configuration is an important part of using the printer effectively.
Incorrect paper settings can cause documents to be cropped, scaled unexpectedly, or printed with unwanted margins.
To configure a print job:
Open the document in your application.
Select Print.
Choose Epson ET-16650.
Open the printer properties or detailed settings.
Select a paper size supported by the printer.
Choose portrait or landscape orientation.
Review scaling and page layout.
Check that the selected paper size matches the loaded paper.
Confirm the settings.
Print one test page before printing a large batch.
The available paper sizes depend on the printer, installed driver, loaded media, and application. Do not select a size that is unsupported by your printer configuration.
For spreadsheets and wide business reports, check the document's page layout separately from the printer settings. A document designed for a small page may need adjustments before it can print clearly on a larger sheet.
8. Choose the Correct Paper Source
When a printer supports multiple paper sources, choosing the correct source can help prevent printing interruptions.
Before sending a document:
Check which paper is loaded in each available tray or source.
Open the document's print settings.
Select the ET-16650.
Review the paper source option if it is available.
Choose the source containing the intended paper.
Confirm that the paper size and type match the loaded media.
Send a short test job.
The available source options may vary according to the driver and printer configuration.
If the printer requests a different paper size, check the settings in both the application and the driver. The printer may be receiving a paper-size instruction that does not match the paper currently loaded.
9. Set Up the Printer for Network Printing
A network connection can allow multiple authorized computers to use the ET-16650 without connecting each computer directly by USB.
First, ensure that the printer and network are functioning properly.
Turn on the printer.
Open its network settings.
Select a supported network setup method.
Follow the printer's instructions to connect it.
Wait for confirmation that the connection is established.
Open printer settings on your computer.
Add the ET-16650 if it is not already listed.
Select the correct printer entry.
Print a small test document.
For successful discovery, the computer must be able to communicate with the printer over the network. Guest networks, network isolation, or organizational firewall rules may prevent detection.
If you are setting up the printer in a business environment, follow your organization's network policies. An administrator may need to configure access for multiple computers.
10. Install Scanner Software for Document Workflows
The ET-16650 provides scanning functionality, but the software needed for scanning may be separate from the basic printer driver.
If you scan contracts, forms, invoices, or other business documents, check the ET-16650 support page for compatible scanner software.
Follow these steps:
Confirm that the printer is connected.
Review the available scanner software.
Verify compatibility with your operating system.
Download the required package if needed.
Install it according to the instructions.
Place the document on the scanner glass or in the document feeder as directed.
Open the supported scanning application.
Select the ET-16650.
Choose the appropriate scan settings.
Preview the document if available.
Start the scan and save the resulting file.
For documents containing small text, review the preview before saving. Selecting appropriate scan settings can help produce a more readable result.
If the scanning application cannot detect the device, check the network or USB connection and confirm that the correct scanner is selected.
11. Test the Driver Before Printing Large Jobs
Before printing dozens of pages, test the installation using a short document.
Load the intended paper.
Check the printer display for warnings.
Open a document with a few lines of text.
Select the ET-16650.
Review the paper size and orientation.
Confirm the paper source if applicable.
Print the test document.
Inspect the output for missing text, unexpected scaling, or incorrect margins.
If the test page prints correctly, try a representative page from the document you intend to print regularly.
Testing with a small job helps identify configuration issues before they waste paper or interrupt a large printing task.
12. Troubleshoot Common ET-16650 Software Issues
