301
Epson 301 on inkjet printer: USB memory device storage full
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
Code 301 in Job Status on your Epson EcoTank means there is not enough storage space on the external USB memory device: delete unnecessary files or insert another drive, or lower Resolution and raise Compression Ratio when scanning.
Safety first
Stop and check this first
- Do not unplug the USB memory device while the printer is saving data, as removing it during a write operation can corrupt files on the drive.
Safe checks you can perform
- Check free space and write protection on the USB memory device
- Lower Resolution or raise Compression Ratio in Scan > Memory Device
- Test with another known-good USB memory device
Leave these tasks to a qualified professional
- Do not attempt this professional task: IT support if using a managed or quota-restricted office USB drive

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
IT support if using a managed or quota-restricted office USB drive
What they doIf your workplace restricts USB drive partitions or enforces write protection, ask IT support to provide an unlocked USB memory device with free capacity.
They must show youthe available writable capacity on the prepared USB memory device.
In writingthe partition or policy change applied and the helpdesk ticket number.
Epson support for the external USB memory device port
What they doIf multiple empty, supported USB memory devices still fail with code 301 on a single low-resolution page, contact Epson support or authorised service.
They must show youa test scan saved to a USB memory device and a clean Job Status history.
In writingthe USB host port inspection findings, warranty coverage, and the case number.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Check free space and write protection on the USB memory device
- Who:
- you, using a computer or a spare USB drive.
- How:
- remove the memory device safely, check its available free space on a computer, confirm write protection is not enabled, and delete unnecessary data to increase free space.
- Result that matters:
- ensuring the USB drive has enough writable capacity for the scan.
- If the drive was nearly full:
- freeing space or swapping drives lets the scan save.
- If space is limited for a large job:
- adjust the scan menu settings to shrink the file.
- Evidence to keep:
- a screenshot of the USB drive's available space before and after cleanup.

Lower Resolution or raise Compression Ratio in Scan > Memory Device
- Who:
- you, on the printer control panel.
- How:
- open Scan > Memory Device and review the basic menu options: reduce the number of documents in the batch, lower the Resolution, or increase the Compression Ratio.
- Result that matters:
- reducing the scanned image file size so it fits on the memory device.
- If the scan completes without code 301:
- the previous file size exceeded free storage.
- If even a single low-resolution page fails on empty drives:
- test another supported USB drive.
- Evidence to keep:
- a photo of the Resolution and Compression Ratio settings on the control panel.

Test with another known-good USB memory device
- Who:
- you.
- How:
- insert a different compatible USB memory device with plenty of free space into the printer's external USB port and run a one-page test scan.
- Result that matters:
- ruling out a partitioned or faulty USB flash drive.
- If the second drive saves the scan normally:
- the original USB drive was full or faulty.
- If code 301 persists across multiple empty USB drives:
- contact Epson support.
- Evidence to keep:
- the Job/Status > Job Status log from the test with the second USB drive.

What it means
In Epson's User's Guide for the ET-5800, ET-5805, and L6550 series ('Error Code is Displayed on the Status Menu' and 'Cannot Save Data to a Memory Device'), code 301 appears in Job/Status > Job Status with the message 'There is not enough storage space available to save the data in the memory device.' Other models may use different codes, and the code alone never proves a hardware part is faulty.
Warnings and stop conditions
- Loweditorial warning
Do not unplug the USB memory device while the printer is saving data, as removing it during a write operation can corrupt files on the drive.

Symptoms and causes
Probable causes · in order
- Insufficient free storage remaining on the USB memory deviceCommon
Existing files on the inserted USB flash drive leave less free space than the printer requires to write the new scanned document.
Evidence: Epson ET-5800 series: Error Code is Displayed on the Status Menu · Epson ET-5800 series: Cannot Save Data to a Memory Device
- Too many original pages scanned in a single job to the memory deviceCommon
Scanning a large stack of originals in one batch produces a file whose total size exceeds the remaining space on the USB drive.
Evidence: Epson ET-5800 series: Error Code is Displayed on the Status Menu · Epson ET-5800 series: Cannot Save Data to a Memory Device
- High scanning Resolution or low Compression Ratio selectedPossible
Choosing a high Resolution in color or a low Compression Ratio under Scan > Memory Device significantly increases the size of each scanned page.
