1 out of 5 eggsUffda Mama, this one is difficult!

Pros: It's still working; sort of. Compared to the Brother MFC-8710dw that I love, it hasn't broken yet.

Cons: So, I've had this printer for a few months now and complain about it every day for one reason or another.

I absolutely loved my Brother MFC-8710dw, but had two break in one year. (I still have one in our front office, and hoping it lasts awhile.)

I am so busy I haven't had time to read the instructions to remedy the specific problems I have, which are:
1) When scanning in grayscale or color, the documents have a gray background.
2) It shuts off overnight, so when I start printing in the morning, it may be hours before I realize I havent turned it on and all docs are lost.
3) It goes into powersave mode after just 10 minutes or so, and takes a very very long time to wake up and print my document. If I'm copying, it won't copy until I hit the Power Save butten THEN the print button.
4) The panel is not user friendly. I've worked with all-in-ones for years...even sold specialty printers back in the day, and this one is DIFFICULT.
5) This unit is way too expensive for the problems I've encountered and the time required for setup and instruction.
6) The prints are not dark enough. Again, probably able to be remedied, but NOT USER FRIENDLY.

I sure wish Brother's printers were more reliable. I hate this OKI but it's still running...

3 out of 5 eggsBeware: NO WIRELESS CARD

Pros: Great device. It is one of the best printers I have ever owned as of this moment. I am in law school, and I print high quantities of various document/cases on a regular basis and this print speed/scanning is top notch and beats anything I have ever owned.

Cons: Does not have a wireless card and cannot achieve network connectivity without a wireless-card or external wireless print server. I would assume that a piece of equipment this advanced with its vast multitasking capabilities would have wireless functionality as well. However, I spent about 2 hours trying to configure it to my home network only to realize that it had no wireless card. So in my opinion, it vastly decreases its value being that I have to now buy an external adapter. So take into account the price to functionality ratio before purchasing. It is a much better deal than any other printer that prints at speeds of 42ppm.

Other Thoughts: Should have been clearly marked as having no wireless networking capabilities. It is misleading not to make it clear on such a high-tech printer.

4 out of 5 eggsUpdated description

Pros: Runs all day every day. Good quality print.

Cons: Newegg updated the description to now say "Monochrome" printer. They originally called it a "Color" printer. It does fax and scan in color, if that helps.
If the power goes out, beware that when the printer comes back on, the TCP/IP address might have changed. You might need to check the machines printout for it's configuration. It causes all networked workstations to loose connectivity until the address is corrected on either the printer, or on all workstations.

Other Thoughts: Reasonably economical on toner usage. Good workhorse for small to medium sized business environments.
