- !You cannot reach the jammed piece without forcing panels or rollers.
What to check first
Step-by-step checks
- 1
Safe first step
Clear the jam fully before restarting the job.
Start with the official recovery step before moving on to parts or deeper servicing.
- 2
Safe first step
Remove any visible scraps and check the rear feed path.
- 3
Consumable check
Reload flatter paper if the same stack keeps jamming.
Background
What this message usually means
Epson uses W-01 for a paper-jam warning on the ET-2850 family. It is lower-severity than the fatal E-series codes because the machine is usually recoverable after the jam is cleared properly, but repeated W-01 events can point to feed or path wear if the same job keeps failing.
Diagnosis
Likely causes
Paper is jammed in the feed or output path.
A torn scrap is still blocking a sensor even after the main jam was removed.
The paper stack or media choice is causing repeated feed problems.
Service
When service or replacement is more likely
- -A W-01 by itself is usually recoverable, but repeat jam warnings deserve a feed-path check.
- -If a fatal E-series code appears with the jam warning, follow the fatal code first.

Source notes
Epson’s ET-2850 support guidance routes W-01 through the paper-jam recovery path rather than the deeper fatal-error path.
Built around Epson EcoTank ET-2850 support guidance and the linked control-panel error-code help for this family. Panel wording can vary slightly across regional ET-28xx variants.
Printer error codes can vary a little by firmware, region, and exact model variant. Use this guide as a family-level starting point and stop if the next step would require disassembly or service-mode changes.
Known family variants: ET-2800, ET-2803, ET-2805, ET-2850
