Fixing Scan-to-Email When It Suddenly Stops
Scanning breaks most often after a mail provider changes its authentication rules, not because the copier failed.
Check authentication first
If your organization moved to modern authentication or enforced MFA, a legacy SMTP login on the copier stops working. An app password or an authenticated relay connector is required.
Ports and encryption
Port 587 with STARTTLS is the common working combination. Port 25 unauthenticated is increasingly blocked outright.
Attachment limits
Large color scans exceed mailbox limits quietly. Lower scan resolution to 200 dpi for text documents and enable compressed PDF output.
When to bring in a technician
Anything that repeats after a proper reset, produces a burning smell, or involves the fuser or high-voltage section belongs with a trained technician. Austintero Co. serves Centennial and the surrounding Denver metro and can usually be on site the same business day.
