My faxes are slow to send. What should I do?


  • Faxes are slow to send.
  • All-In-One models:
    • Stylus Office BX305FW Plus, Stylus Office BX310FN, Stylus Office BX320FW, Stylus Office BX625FWD, Stylus Office BX630FW, Stylus Office BX635FWD, Stylus Office BX935FWD
    • Stylus Photo PX830FWD


You may experience slow faxing speeds, which may become more evident when sending multiple pages at a time. This is because the 'V.34' communication setting is disabled by default. This may be particularly noticeable if you have previously owned an earlier fax-capable Epson product; this is because the 'V.34' mode was enabled by default on earlier models.

To solve the problem, navigate to the Fax Settings menu using the printer's control panel and enable the 'V.34' mode. For instructions on how to access the Fax Settings menu for your printer or for information on the 'V.34' mode, refer to the user's guide for your product which is available on the Epson support site.
