You hit print, the file lands in the queue, and your Epson EcoTank ET-2850 just sits there doing nothing. Maybe the status reads "offline," maybe the page slides out completely blank, or maybe the printer simply ignores every job you send. Whatever the symptom, the cause is almost always one of a handful of fixable issues: a stuck queue, a dropped Wi-Fi connection, outdated software, or ink that needs attention. The fixes below are ordered from the easiest and safest to the most involved, so start at the top and stop the moment your test page comes out clean.
Start With A Power Cycle And A Quick Test Page
Before changing any settings, turn the printer off and back on, then send one test print. Epson lists this restart as the first step for an ET-2850 that shows offline or refuses to print, and it clears a surprising number of temporary glitches. While the printer boots back up, glance at the LCD to confirm there is no error showing and that paper is actually loaded in the tray.
If the test page prints normally after the restart, you are done. If it does not, leave the printer on and move to the next step, which tells you whether the hardware or the connection is to blame.
Print A Nozzle Check To Isolate The Problem
A nozzle check pattern, run directly from the printer's control panel, is the fastest way to separate a hardware fault from a connection fault. Because the nozzle check prints without any computer involvement, the result tells you exactly where to focus next.
If the nozzle check prints, the printer itself is healthy and your problem lives in the print queue or the network connection, so jump to the queue and Wi-Fi fixes below. If the nozzle check will not print at all, check the LCD for an error message and clear it before going any further.
Clear The Windows Queue And Turn Off "Use Printer Offline"
On Windows 8 through 11, a single stalled job can freeze every print after it, and Windows sometimes flips the printer into an offline hold state. Clearing the queue and unchecking the offline box fixes both at once.
- 1.Open Control Panel > Hardware and Sound > Devices and Printers.
- 2.Right-click your ET-2850 and choose "See what's printing".
- 3.Right-click the stalled print job and select Cancel, then click Yes.
- 4.In the print window, select "Printer" from the menu and deselect the "Use Printer Offline" checkbox so Windows stops holding your jobs.
With the queue emptied and the offline box cleared, send a fresh print and the job should go through.
Clear The Mac Queue And Re-Add The Printer Over Bonjour
On macOS, the equivalent fix is to empty the queue and, if the printer still shows offline, remove it and add it back using the Bonjour connection. Bonjour is what lets your Mac rediscover the printer cleanly on the network.
- 1.Open the Apple menu > System Settings (or System Preferences) > Printers & Scanners.
- 2.Double-click your printer to open the print queue, select the pending job or jobs, and click the delete icon.
- 3.If it still shows offline, select the printer and click the minus (-) button to remove it.
- 4.Click the plus (+) button, select your printer with Kind set to "Bonjour", choose the driver from the Use dropdown, and click Add.
Once the printer is re-added through Bonjour with the correct driver, try printing again.
Restart Your Router, Then Your Computer
For wireless connection problems, Epson's guidance is to unplug the router's power cord, wait a brief period, plug it back in, and try printing again. If that does not restore the connection, restart the computer as well and retry the print.
One detail matters a lot here: the ET-2850's own radio is 2.4 GHz only (IEEE 802.11 b/g/n), so it cannot join a 5 GHz network. Make sure the printer is connecting to your 2.4 GHz band, and if your router broadcasts one shared name across both bands, give the 2.4 GHz band its own network name so the printer always lands on the right one.
Reconnect The Printer To Wi-Fi From The Control Panel
If the Wi-Fi icon on the LCD shows no connection, walk the printer back onto your network using the built-in setup wizard.
- 1.Press the home button if necessary, then select "Wi-Fi Setup" and press OK.
- 2.Select "Wi-Fi (Recommended)" and press OK twice.
- 3.Select "Wi-Fi Setup Wizard" and press OK.
- 4.Select your network name and press OK.
- 5.Enter the wireless password; if the connection succeeds, press OK to exit.
Choose your 2.4 GHz network and enter the password for that band. When you are done, confirm the Wi-Fi icon on the LCD shows a connected status before sending a print.
Update Or Reinstall The Printer Driver And Software
Out-of-date software is behind a large share of printing failures, especially after an operating-system update. The current driver lives on the official ET-2850 support page under the Downloads tab.
Open the Downloads tab, manually select your operating system, and install the latest drivers and utilities package Epson lists for the ET-2850. On Windows, you may need to uninstall the old software first and then reinstall the fresh package so the new driver takes over cleanly.
Check The Ink Tanks And Run A Head Cleaning For Blank Or Faint Pages
The ET-2850 is a cartridge-free EcoTank, so there are no cartridges to reseat. When pages come out blank or faint, the cause is usually low ink in a refillable tank or a clogged print head, and the fix is ink and a cleaning cycle, not a cartridge swap.
First, make sure each ink tank is at least one-third full. Then run a head cleaning from the printer: load plain paper, press the home button, select "Maintenance," select "Head Cleaning," and press the start button. Reprint the nozzle check to see whether the lines have filled in.
Never turn off the product or open the scanner unit during a cleaning cycle. If you see no improvement after cleaning up to three times, turn off the product and wait at least 12 hours, then run a nozzle check and clean again. If output is still poor, you can run Power Cleaning from the home button > "Maintenance" > "Power Cleaning," but only when each tank is at least one-third full, since running it low can damage the product. After a Power Cleaning, turn the product off and wait at least 12 hours before running another.
Print From Your Phone With Smart Panel Or AirPrint
If your computer is the holdout, try printing from a phone or tablet to confirm the printer is working over the network. The official Epson Smart Panel app lets you set up, monitor, print, scan, and view ink levels from a smart device. It requires iOS 11.0 or later, iPadOS 13.1 or later, or Android 5.0 or later.
On Apple devices you can also use AirPrint straight from an iPhone, iPad, or Mac, and the ET-2850 supports Mopria Print Service on Android as well. Make sure your phone and the printer are on the same network, or connect the device directly to the printer using Wi-Fi Direct.
Reset Network Settings Or Restore Defaults As A Last Resort
If nothing above works, reset the printer from the control panel. This step is destructive: choosing a reset clears the corresponding stored settings, so you will need to set them up again afterward.
- 1.Press the home button, then select "Settings."
- 2.Select "Restore Default Settings."
- 3.Choose "Network Settings" to clear only your Wi-Fi configuration (you will then need to re-run Wi-Fi setup), or choose "Clear All Data and Settings" to reset all control panel settings and any stored information for a full factory reset.
- 4.Press OK to confirm.
The other options on this menu, "Copy Settings" and "Scan Settings," reset only those specific areas if you ever need them. After a network reset, walk through the Wi-Fi Setup Wizard again using the steps further up this guide. If the printer still will not print after a reset, contact Epson Support.
Frequently Asked Questions
Does the Epson ET-2850 work on a 5 GHz Wi-Fi network?
No. According to the official User's Guide, the ET-2850's wireless radio is 2.4 GHz only (IEEE 802.11 b/g/n), so it cannot join a 5 GHz band. If your router shares one network name across both bands, give the 2.4 GHz band its own name so the printer always connects to the right one.
Why is my ET-2850 printing blank pages even though it has ink?
Because this is a refillable EcoTank with no cartridges, blank or faint pages usually point to low ink or a clogged print head. Confirm each tank is at least one-third full, then run Maintenance > Head Cleaning from the control panel and reprint the nozzle check. If there is no improvement after three cleanings, wait at least 12 hours and try again or run a Power Cleaning.
How do I print from my iPhone or Android phone to the ET-2850?
Use the official Epson Smart Panel app, which needs iOS 11.0 or later, iPadOS 13.1 or later, or Android 5.0 or later. You can also use Apple AirPrint from an iPhone, iPad, or Mac, or Mopria Print Service on Android. Keep the phone and printer on the same network, or connect directly through the printer's Wi-Fi Direct.
What does "Use Printer Offline" do and how do I turn it off?
On Windows, that checkbox tells the system to hold your jobs instead of sending them, which makes the printer appear offline. Open Control Panel > Hardware and Sound > Devices and Printers, right-click the ET-2850, choose "See what's printing," then select "Printer" and deselect the "Use Printer Offline" checkbox.
Will resetting the printer erase everything?
It depends on which reset you pick. From the home button > Settings > Restore Default Settings, "Network Settings" clears only your Wi-Fi configuration, while "Clear All Data and Settings" resets all control panel settings and any stored information for a full factory reset. Choose the narrowest reset that fits your problem and press OK to confirm.
