"lacks basic FAX capability for accurate date and time"0.5 starson by brightershade
Pros: lots of wired and wireless network options, including WPS support; double-sided printing and scanning; RAM can be expanded
Cons: with all the built-in network options, still lacks Network Time Protocol support to preserve the current date and time; often jams during double-sided operations
Summary: This model is unsuitable as a FAX machine because it lacks a basic capability found in earlier models: it loses the current date and time after even a split-second power interruption, Due to the heavy power draw of the laser in this model, you can't plug it into an uninterruptible power supply (UPS), so anytime you send or receive a FAX, the time could be wrong -- especially if you receive FAXes.
I've had earlier Brother MFC models and all of them possessed the capability to preserve the date and time after power outages.
No where in product literature does Brother disclose this degraded functionality for the MFC-8890DW. What's even more bizarre, is that this model is loaded with network features, so it would have been absurdly simple for Brother to build in Network Time Protocol (NTP) support -- but Brother's product manager for the MFC-8890DW chose for Date and Time services to be irrelevant.
Brother obviously decided that FAX on this model was not important, so if FAX is important to you -- look elsewhere.
