EPSON Error Code 093.933

This error code indicates a persistent paper jam or a sensor malfunction within the printer's fuser unit or the paper output path.

1. 1

   Turn off the printer completely and unplug it from the power outlet. Wait for at least 5-10 minutes to allow the fuser to cool down, as it operates at high temperatures.

2. 2

   Open all accessible covers and trays (front, back, side, and top) to gain full access to the paper path. Carefully inspect for any visible paper scraps, torn pieces, or foreign objects, especially around the fuser unit (often a unit with warning labels about heat).

3. 3

   Gently pull out any jammed paper in the direction of the paper's normal travel, avoiding tearing. If paper is stuck in the fuser, use extreme caution not to damage the fuser film or rollers.

4. 4

   Use a flashlight to thoroughly check all nooks and crannies for small, hidden paper fragments. Even a tiny piece can trigger the sensor.

5. 5

   Remove and reinsert the toner cartridge(s) and any imaging units or waste toner boxes, ensuring they are seated correctly. Sometimes, improper seating can obstruct the paper path.

6. 6

   Close all covers securely. Plug the printer back in and turn it on. Allow it to initialize and see if the error clears.

7. 7

   If the error persists, try printing a test page from the printer's menu (if accessible) to see if the paper transport issue reoccurs.

8. 8

   If you have access and feel comfortable, gently wipe down any visible paper sensors in the paper path with a lint-free cloth, as dust can sometimes interfere with their operation.

You should consider calling a specialist if, after performing all DIY troubleshooting steps, the error 093.933 persists. This is especially true if you suspect the jam is deep within the fuser assembly and you cannot reach it without applying excessive force, or if you believe a component like a fuser roller or a paper sensor is physically damaged. If the error appears immediately upon startup without any paper in the path, it strongly suggests a sensor or internal hardware failure that requires professional diagnosis and repair, as these components are often not user-serviceable.
