E-21
Epson Printer
Severity:What Does This Error Mean?
Error E-21 means paper is jammed inside the printer and needs to be removed. The printer has detected paper stuck in the feed path. You need to carefully locate and remove all jammed paper before printing can continue.
Affected Models
- Epson WorkForce WF-7720
- Epson WorkForce WF-7710
- Epson WorkForce Pro WF-4730
- Epson WorkForce WF-3640
- Epson Expression Photo XP-8600
Common Causes
- Paper that is too thick or too thin for the printer caused a feed failure
- Multiple sheets were fed at once due to static electricity or damp paper
- Paper that was already crinkled or folded caused a jam
- The paper guides were not adjusted to the paper size, allowing it to skew
- A small scrap from a previous jam was left inside and caused a new jam
How to Fix It
-
Turn the printer off. Never try to pull jammed paper while the printer is powered on.
Pulling paper while the motor is running can damage the paper transport mechanism.
-
Open the rear access cover and look for jammed paper in the rear paper path.
Most WorkForce printers have a rear cover that opens for easier jam clearing.
-
Gently pull out the jammed paper toward you with both hands. Do not yank it out.
Pull slowly and evenly. If you feel strong resistance, stop and look for what is catching the paper.
-
Open the front cover or lift the scanner unit to check the front paper path as well.
Paper jams can span both the front and rear paths on some models.
-
After clearing all paper, close all covers and power the printer back on. Try printing again.
If E-21 returns immediately, a scrap of paper is still inside. Use a flashlight to check.
When to Call a Professional
If you cannot locate or remove all the jammed paper, do not force it. A technician can open the printer and safely remove hidden jams. This typically costs $40 to $70 at an Epson service center.
Frequently Asked Questions
What type of paper should I use to avoid E-21?
Use plain 20 lb (75 gsm) bond paper for everyday printing. Make sure it is dry and not crinkled. Fan the paper stack before loading to separate sheets and reduce static.
E-21 appeared but I cannot find any jammed paper. What should I do?
Look very carefully with a flashlight — the jammed piece may be deep inside. Also check under the paper tray and near the output rollers. A piece as small as a corner of a page can trigger E-21.
How can I prevent paper jams in my Epson WorkForce?
Keep the input tray from being overfilled — stay under the fill line marked on the tray. Adjust the paper guides snugly against the paper stack. Avoid mixing different paper types in the same tray.
