- !W-01 returns on clean paper after several careful clears.
- !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.
Before the message
What users usually notice first
Messages like this often appear after the printer fails one of its normal startup, supply, or paper-path checks and cannot return to ready state cleanly.
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.
Avoid wrong turns
Common misreads of this message
- -Treating the message like a confirmed failed part instead of a support clue about which system has stopped the printer.
- -Assuming no physical path issue exists just because no full sheet is visible at first glance.

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
