Problems out of thebox
584871
I purchased this scanner and hooked it up to my Subaru 2002 forester.  It didn't work.  When I called the company, they immediately knew of the problem, and told me I would need to ship the code reader back to them to have the chip re-programmed.  Best part is that they want me to pay the shipping!  Innova should really recall all their 3030 scanners and fix them, or offer free shipping to have them reprogrammed.  It might work for many other cars, but the Subaru is OBDII compliant, and the code reader should work out of the box.

One of the monitor is not working right out of the box, so I am returning it.

I am having an out-of-the-box issues with the calendar function not working.  I spent 3 hours on MS Surface pro 3 website and gave up since there is no place to get to get real help, no tech support number, NOTHING!

Out of the box, the unit froze up within a half hour of use and has performed poorly ever since. The company said I needed a firmware update, which requires a computer which I do not own. Waiting on a friend to unzip the file and see if it solves the problems, otherwise I hope to return the unit before the return cut off date, which is quickly approaching. UPDATE 5-15-15...Got the firmware update loaded in and now it works at 100 percent! All problems solved!

I am going to guess that the machine works fine, but I haven't been able to get it to "works".  After well over 6 hours of time, I can't use any machine functionality.  After 4 hours I was able to print wirelessly from one computer, but after printing 3-4 times over the course of 3 days,  I lost that functionality and am now trying to troubleshoot my wireless connection to the machine.
A summary of problems:
1. I wasn't warned up front about the amount of time it would take to set-up the machine hardware, install software, get the network connection to work, then go through the process of learning even the most basic features of all the functions.  My expectation was that I could have this set-up an functioning in 1 hour, I'm at 6 and it isn't functioning and all I have tried is printing.  While I am not a technical wizard, I am going to guess for a consumer or a sole proprietor I rank in the top 20% for technical knowledge of hardware and networks.
2. Consistent with the above, the documentation looks like it assumes that the person setting up the machine has some pretty good networking knowledge.  The instructions don't separate a "corporate install" from a "consumer/sole proprietor" install.
3. The documentation is some of the worse I have ever seen in my life.  The machine inherently has some complexity, due to all the functionality.  Brother makes it more complex by cramming instructions for 4 different models in the same instructions. While I was trying to troubleshoot the lost network connection, I had to look closely at which model the instruction solution was describing.
4. There is quit a bit of documentation that is provided, yet it references online documentation quit a bit also.  It seems that rather than splitting the documentation between the hard copy an the network, all the critical parts should be available by paper or alternatively, other than the quick start all the documentation should only available online (which has its own set of problems). The split documentation didn't work for me.
5. When I installed the standard software pack, it uninstalled a working version of PDF Convertor software and installed PaperPort.  I am going to guess there was a splash screen telling about this change somewhere.  To the best of my knowledge I haven't experienced this sort of modification in the past without more emphasis on the change being made, so I was unhappy with the "surprise".  So now I am not only trying to learn the hardware, I have to learn the software installed for non-hardware functions or try to reinstall my PDF Convertor software.  I am guessing each software has the same functionality, but this is adding unnecessary time and frustration to the start-up process.
6. The Brother Website is a joke.  They want me watch their videos rather than answering specific questions.
7. In Brother's defense I have not tried to contact their "Help Desk".  Based on what I have seen so far, I won't be able to speak to a real person until I have sat through long automatic attendants that won't give me a easy course to address my specific concerns, will be confusing, and will make me pay a penalty of long waits to actually speak to a person.  I'll probably have to keep myself from throwing up, because at some point in automated attendant jail, they  will tell me how important I am as a customer.
I am going to continue to slog my way through this start-up and at some point may end up appreciating a machine that many assert is a quality tool. I am assuming that this will occur prior to me taking a sledge hammer to the device and  going to a simple plugged in printer for small printing jobs, Kinkos for large jobs and copying,  and a page fed scanner (like ScanSnap) for scanning.  If I do grow beyond a sole proprietor, I may make a point of keeping Brother off my vendor list just as a matter of principal.

First pc circuit project had three glaring errors, and simply wouldn't work as written. Makes me worry about the line voltage projects.

Firmware releases and updates break presentations. This occurred on three different occasions, with the last one being the final straw. Support is through email only and responses can take a long time. You are also required to sign up for an account in order to place help tickets. Worked with a gentleman (Lyndon A.) from support who was not able to fix my problem. He seemed more concerned selling me priority support, which is basically the same cost as a Microsoft support phone call. (400 dollars for a call back w/in 4 hours) and closing tickets as soon as possible. We spent close to three thousand dollars on one of their products and we are down on our digital signage and have been for over a month.

I would highly recommenced you try a different solution.

I have had more issues in the past 2 days since purchasing this, then I have in all the years of the previous versions.  It's very frustrating when a box literally pops up on the screen "crash" and then it closes.

I had a problem with the printer. Flashforge helped me by sending me a whole new motherboard to fix the problem.
UPDATE: 07/13/2018, had the same power fault, they are sending a second motherboard to be replaced.

In hindsight I would recommend saving your money in favor of a more robust solution, unless you don't need the system to operate reliably remotely.

Also, the customer support people do not seem to return emails.

Far too many problems include errors in the solution method.

Make sure you have the original windows box or you will have to write and get a number from fast and wait for it. Dosr not just load you have to answer questions. My advice; save time and find a computer wizard.

I am having to revise my previous review of this product, and downgrade the rating considerably. I have been using this PC for about six months now, and all kinds of oddball problems have been plaguing this unit.

First, the built-in ethernet adapter failed, and I had to get an external USB ethernet "dongle" to get back online.

Then, I began getting an error message at least once a day: some odball error code that requires rebooting the PC to get it running again.  Multiple emails to ASUS and still no solution.

Finally (so far), the sound just quit working altogether. All of the settings are OK, but...no sound.

I'm thinking the motherboard is slowly failing, since all of these problems are related to on-board components.  I really expected to get more than 6 months out of this PC.

Can't recommend this one at this point; looked like a great value but it's falling apart right before my eyes.

Some of the pieces have connection points that are off-center and will not connect to other pieces.  Fixable with a router or jigsaw, but I expect the QA to catch these issues prior to packaging.

I was impressed by R.A. Edington's review of the  DSM-520. I am putting in this comment because I recently bought a DSM-320, and had many of the same issues. I am disappointed that Dlink has not fixed these problems in the DSM-520, which I was considering buying, but have decided to hold off on until they fix the serious shortcomings. I am sorry to say that poor quality seems to be on the rise, especially with regard to devices that have a large software component, like the DSM-520. For example, I bought an HP iPAQ hx4700, a top of the line PDA. It had many software problems until I upgraded the firmware - AND it took a very long time for HP to provide the fixes. Shame on these and other manufacturers who take short cuts and leave us to deal with the mess. Good quality is expected up front, not a nice to have.

Out of box, when initializing an error message indicating a paper jam kept popping up.  I tried everything.  After researching online, seems this has happened to a couple of people.  Had to return to Amazon.

The printer's printing functions work as expected; however, there has been a mechanical issue with the top printer door since I unpacked the printer. The door does not function smoothly and "pops" when opened or will slam when closed if not carefully closed. I am currently working with Brother to find a resolution, but I am disappointed because a product should function correctly right out of the box. Instead, I have to spend hours on the phone with customer service and possible visit a service center to have the unit repaired. So instead of a working printer, I now have project on which my time will be spent.
