What usually causes it
- The scan exceeds a device-configured sending limit.
- The mail service may also impose an attachment/message limit.
- High resolution, full color, or many pages can make the file too large.
What to try
Try a smaller scan
Use fewer pages or split the document into logical parts.
Reduce file size safely
Lower resolution or use appropriate compression if image quality remains acceptable.
Check configured size limits
If policy allows, have the administrator compare the device and mail-service maximum sizes.
Retry with the smaller job
Confirm the original destination accepts the reduced file.
After each corrective action
Retry the same operation that produced 2204. If it now works, stop there rather than changing unrelated printer, network, or service settings.
If the code returns
If even a small scan gives 2204, the configured limit may be unusually low or the wrong profile may be in use.
When service may be needed
These settings affect network or mail security. If the required server, authentication, or certificate values are managed by your organization, have the administrator make the change rather than guessing.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
