Pro tips for better faxes

Retarus is continuously updating its infrastructure to always achieve optimum delivery rates and quality in fax transmission.

As a customer of our fax services, however, you can also have a positive impact on the successful delivery and perfect legibility of your faxes. Below, we reveal how.

Cover page: Telecommunications providers across the world (especially in Asia!) frequently take action against so-called Short Duration Calls, which place a particularly heavy load on their infrastructure. The carriers also often suspect that spam is behind such short connections. For this reason, they break off attempts to create dial-up connections or sometimes block connections entirely. Yet modern devices can also transmit legitimate faxes in well under 40 seconds. That’s why it can be useful to add a cover sheet before the actual fax in order to protract the length of the call (with Retarus you can even adapt cover sheets individually to match your corporate design).

Data quality: Network operators also consider the increasing recurrence of “retries” – in other words the repeated dialing of the identical number – to be grounds for suspecting spam activity. To also prevent being blocked in such a case, your distribution list containing recipient details should always be well maintained. The Retarus EAS portal (Enterprise Administration Services) can assist you in this regard. The reports in the portal list in detail the numbers which have been identified as invalid, allowing you to remove them from your database before future transmissions are made. We recommend using the data from one or two monthly reports for this purpose.

No greyscale: For the best rendering you should avoid documents containing greyscale text or images. This means that when generating faxes you should ensure that the document is set to black & white rather than greyscale – in the full version of Adobe Acrobat the corresponding setting is called “Print color as black”. This enables your recipients to read faxes much more clearly and facilitates automated processing if required.

Fonts: Sans serif fonts (e.g. Helvetica or Arial) are easier to read and can be better processed automatically than fonts containing serif (e.g. Times New Roman or Georgia) – particularly at low resolution. That’s why they should be preferred for faxes.
