Epson EcoTank ET-4850
has a paper jam.
Epson EcoTank ET-4850 has a paper jam? A paper-jam warning can remain after the torn sheet is gone. Remove paper in the feed direction and clear the sensor path without forcing the rollers. On this tank model, check Epson Smart Panel, ADF sensing, fax-ready network setup, and 522 ink flow first.
Try these in order.
Stop as soon as the printer behaves. Each step removes one likely cause without changing settings you may need later.
- The jam warning stays on after removing a page
- Paper enters crooked or stops halfway
- The printer makes a clicking sound while feeding
- Epson EcoTank ET-4850 behavior points back to Epson Smart Panel, ADF sensing, fax-ready network setup, and 522 ink flow.
- 01
Turn it off and open every access door
Power down normally, unplug it, then check the rear access panel, cartridge or printhead path, and output area with a flashlight. On the Epson EcoTank ET-4850, use Epson Smart Panel for this check.
Expected result: You can see and reach the jammed paper or fragment.
- 02
Pull paper in the feed direction
Grip both sides of the sheet and pull slowly toward the output path. Avoid yanking backward against the rollers.
Expected result: The sheet comes out in one piece without tearing.
- 03
Reload a small, flat stack
Use fresh paper, keep the stack below the fill line, and set the side guides so they touch the paper without bending it.
Expected result: A single test page feeds straight without jamming.
Match your symptom, jump to the right fix.
If: A torn fragment is stuck inside
Then: Remove it carefully in the feed direction, then check for a second fragment.
If: The warning persists after the paper is gone
Then: A sensor is still blocked or a door is not fully closed. Recheck and power-cycle once.
If: It jams only with a full stack
Then: The paper is curled or damp, or the tray is overfilled. Use fresh paper below the fill line.
Usually one of these.
- Epson Smart Panel, ADF sensing, fax-ready network setup, and 522 ink flow is the model-specific checkpoint to verify first.
- A small piece of torn paper is blocking a sensor or roller.
- The paper stack is curled, damp, mixed-size, or over the tray limit.
- The paper guides are loose and the sheet enters at an angle.
Move to the deeper fix.
Reset the jam sensor
With the printer unplugged for 60 seconds, rotate only accessible rollers by hand and check that every guide and access door is fully closed.
Expected result: The jam warning clears after power is restored.
Test with one sheet
Feed one sheet from the recommended tray. If one sheet works but a stack jams, the tray or paper condition is the likely cause. Use the official Epson support page for the exact Epson EcoTank ET-4850 package before changing firmware or resetting the device.
Expected result: One sheet prints; a full stack may still jam if paper is damp or curled.
- Do not use tweezers near rollers or electronics unless the fragment is loose and clearly visible.
- Never yank paper backward; it can tear the sheet and damage the feed rollers.
Before you reset everything.
Can I use tweezers to remove a paper jam?
Only for a loose, visible fragment that you can reach without touching the rollers or electronics. If paper is wrapped around a roller, follow the official service access instructions. On this model, start with Epson Smart Panel and the official support instructions.
Why does the jam warning stay on?
A small fragment, open cover, or unreset sensor can keep the warning active even after the main sheet is removed.
Does damp paper cause jams?
Yes. Damp or curled paper sticks together and feeds crooked. Use a fresh, dry ream.
Should I pull the paper out backward?
No. Pull in the feed direction to avoid tearing the sheet and stressing the rollers.
