Introduction
Spam or junk faxes are more than just a bother; they waste paper and your time.

Junk fax blocker: Save paper and time
With fewer interruptions, you’ll be able to stay on task at work.
Junk fax blocker allows users with Caller ID on their phone lines to block the printing of unwanted faxes. Once you set up this feature, those “spam” faxes will not print out.
This feature is especially useful in dense urban areas where phone numbers change over more frequently, causing more junk faxes.
By using Junk fax blocker, you can:
- Stop wasting paper caused by faxed solicitations.
- Cut out the time it takes to track down senders and ask them to remove you from their lists.
