What to check first
Step-by-step checks
- 1

Turn the printer off and back on once before trying to print again.

Check for visible paper jams before restarting the job.
- 3
Safe first step
If the printer returns ready, test with one page only.
Background
What this message usually means
Epson uses E-01 for a fatal printer error on this EcoTank family. It is a broad machine fault rather than a routine paper or ink warning, so the first step is to restart the printer and check for a paper-path problem before assuming the printer can safely continue normal jobs.
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
A serious internal printer fault was detected during startup or printing.
A paper jam or obstruction left the device in an unrecoverable state.
The printer could not clear an internal hardware or transport error.
Service
When service or replacement is more likely
- -This is a restart-first, escalate-second fault rather than a maintenance-box or cartridge issue.
- -If the printer never reaches ready, stop trying to queue more jobs.
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 any supply-related wording means the next step is automatically to buy a cartridge, toner, drum, or printhead.
- -Assuming no physical path issue exists just because no full sheet is visible at first glance.
