  • !W-01 returns on clean paper after several careful clears.
  • !You cannot reach the jammed piece without forcing panels or rollers.
If the printer still starts normally: Finish the first checks once, then stop if the same message repeats or the printer still cannot return to ready.

What to check first

Step-by-step checks

  1. 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. 2

    Safe first step

    Remove any visible scraps and check the rear feed path.

  3. 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

Most common

Paper is jammed in the feed or output path.

Common

A torn scrap is still blocking a sensor even after the main jam was removed.

Possible

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.
