How Auto Resume on Partial Send works?

When sending a fax, temporary connection issues can sometimes interrupt transmission, causing only part of the fax to be delivered. To help you save time and reduce page usage, Fax.Plus offers an intelligent feature called Auto Resume on Partial Send. This feature ensures that when a fax is only partially sent, the system can retry automatically from the exact page where the transmission stopped.

What Is a Partially Sent Fax?

A fax is considered partially sent when:

• The connection is established successfully.
• Some pages are transmitted to the recipient.
• A connection failure, noise on the line, or remote machine error interrupts the transmission before completion.

Example:
If you send a 50-page fax and the connection fails after 18 pages, the fax enters a partially sent state.

What Auto Resume on Partial Send Does

When enabled, Fax.Plus will automatically:

• Detect that a fax was partially sent.
• Create a background continuation job that resumes sending from the next unsent page.
  Example: If 18 of 50 pages succeeded, the next attempt starts at page 19.
• Keep your fax in the Outbox with a Sending status during resumption.
• Continue retrying until:
  • All pages are successfully delivered, or
  • A final blocking error prevents delivery.

How to Enable Auto Resume on Partial Send

1. Go to the Send Fax page
   In the main Fax.Plus interface, open the Send Fax tab.
2. Open the Settings menu
   Click the gear icon labeled Settings at the bottom right of the Send Fax screen.
   This opens the pop-up window containing transmission options.
   
3. Locate the Auto Resume on Partial Send option
   In the settings pop-up, look for the checkbox labeled “Auto Resume on Partial Send”.
   It appears as the third option in the list, below “Auto Retry on Failure.”
4. Enable the feature
   Click the checkbox to enable Auto Resume on Partial Send.
5. Save your changes
   Click the Send button to apply the setting.
   This saves the preference to your profile for future faxes.

When Should You Keep It Turned OFF?

There are rare cases where the recipient must receive:

• All pages in a single continuous transmission, or
• A fax machine that does not handle multi-part faxes well
• If continuity is critical, you can disable Auto Resume.

How It Appears in Your Fax History

While Auto Resume Is Enabled

• The fax stays in Outbox → Sending
• You will not see a “partially sent” state during transmission
• Once fully delivered, it appears in Sent as a successful fax

If All Pages Cannot Be Sent After All Retries

• The fax moves to Sent
• Status becomes: Canceled (Fax partially sent)
• The failure report shows how many pages were successfully delivered

Billing & Page Counting

You are charged based on:

• The total number of unique pages sent, summed across all partial retries
  or
• The total duration, if that cost is larger

Where You’ll See "Partially Sent" Information

If the fax does not complete successfully:

• Fax Status modal
• Fax PDF viewer
• Fax confirmation or failure report
• “Partially Sent Faxes: X” indicator (only shown if applicable)

Frequently Asked Questions

Does the recipient receive multiple fax transmissions?

Yes. Each partial retry generates a separate fax transmission, starting from the next page.

Will the recipient know it was partially sent?

They will receive the pages as normal, but they may notice multiple fax receptions.

Examples

Scenario 1: Successful Resume

• You send a 100-page fax
• First attempt sends 30 pages, then connection drops
• Auto Resume sends pages 31–100
• Result: Success (100 pages sent)
• Recipient may receive two separate fax transmissions

Scenario 2: Resume Fails After Retries

• You send a 100-page fax
• First 30 pages succeed, then fails
• Continuation attempt encounters a recipient-busy signal
• System retry and user retry apply
• No successful connection after all retries
• Result: Canceled (Fax partially sent)
• Failure report lists 30 pages sent
