Brother MFC 9840 CDW-disappointed with Color Printing and Color Copying
590190
I am very disappointed with color printing and color copying. There is no quality in color printing. I can see yellow or blue color on the background of the paper, and color combinations are also bad. As I am not a technical person, I usually use printer in default settings.  In Default settings, it does not print colors properly. Also, does not copy properly in color. Dark colors look in blue. I have to go outside to do color printing or copying nd spend more money. I felt I have paid too much money for this printer as it lacks proper functioning. As far as the back & white, priting, Copying, scanning, anf other things are concernec, it does a great job. There may be some mechanical problem with the one I bought, and may not be the same with all other machines.

Thank you.

What irritates me is that the unit cleans itself by using ink, of every color.
If you want to fax something: REFILL CYAN.  Just when you want to print a b&w postage code: REFILL BLUE.  Why do you need to REFILL BLUE for a black & white document, with the printer properties set to grayscale or black & white?

The color cartridges are half the size of the black cart. So, even if you rarely print color, just when you need to run a copy for school: REFILL YELLOW.

I wanted to go back to Epson, since our old color printer didn't have this problem.  But ALL MANUFACTURERS DO IT NOW!  So check ink cartridge size and prices on whatever you're looking at.  Ink prices will have a heavier weight on your wallet than the machine price.

At first the brothers MFC 490 CW didn't recognized the cartridge. I thought I was screwed. ( I only needed to replace the yellow). So this is what I did.
Step 1. Remove all cartridges from the printer
Step 2. Replace cartridges one by one. First the black, then the....etc..make sure you slip in the replacement cartridge while reinstalling all of the cartridges.
Step 3. Watch the brothers printer do its magic.
JUST LIKE AMAZON, this company LD is not a paradigm (a typical example or pattern of something, a model) because like amazon they look for new ways to get us to save and not follow the old model of distribution and cause us to pay unnecessary up charges and fees. One color bundle would have cost me over $25.00, but with LD Compatible, I HAVE 10 cartridges for less than brothers and others prices...now why cant Brothers do the same thing,,,love the item and love Amazon..

DO NOT BUY THIS.  My Brother MFC 9840 would not recognize it and I ended up recycling them without printing a page.

I am generally pleased with Brother printers and bought this one at a good price point. After working very well for approximately 10 months, it started "spotting" on my documents and smearing the ink (two separate problems). I purchased an authentic Brother ink cartridge from Amazon, but the problem persists to this day. I figure that one of two things occurred. Either Brother has some quality control problems as the partial result of their great success or I received a bootleg printer and I should have known that the price was too good to be true. After many years with Brother, I no longer have confidence in their products. I am done!

After some research, I switched to Konica-Minolta (Bizhub). At the end of the day, all I want is a crisply printed document or letter.

I bought "like new" from Amazon Warehouse and supposedly under warranty only to find after 30 days it quit printing color and the warranty had expired a YEAR before I bought it.  After discussing with other product owners on HP forums I discovered this is a common flaw where it will print test pages but no other pages in color, no matter what you do.  This is why there are always used Amazon Warehouse models for cheap.

So you might get a few days of color printing.  It makes a decent B&W printer but for $100 there are far better printers out there.

HP has really dropped quality out of the equation. Brother beats them in quality printers.  Avoid this printer like the plague.

The idea of a multifunction printer, scaner, fax, etc., is a good idea, but this implementation is cludgy and overpriced.  To start, the base model does not include fax capabilities, which you must add later for an additional cost.
All in all, the Brother MFC-8820DN is a much better value (around $600) and has everything included.

I was disappointed in this printer.  It makes outstanding color copies.  However the cartridges are very expensive.  Each one  contains a microchip, I think to measure the ink suppy.  Because of the microchip there are no generic cartridges available.  The cartridges supplied with the printer are designed to initiate the printing process and appear to contain very little ink.  If you plan on buying this printer, plan on buying extra cartridges right away.  Three cartridges (color or black) will cost you about the same as the printer.

No where near oem quality - not worth it if you need your color to match when printing.

I bought a MFCJ6920DW printer in September of 2014 and in January of 2016 it died.
Brother replaced it and in September of 2017 this too crashed.
After many calls to Brother about a replacement their decision was the machine was now out of warranty so you are dead out of luck just like the printers that they supplied me with.
So to you all out there  be very careful when considering purchasing products from Brother.

I bought my RX680 it was no way this price.  I paid about 149+ shipping a couple years ago.  Uses alot of ink.  Worked well for awhile.  Now for some reason colors are off.  I used to print and make my own cd's.  They came out great.  Now I just waste a cd printing on it.  You can't even read the text on the cd's anymore.  Don't know what's wrong with it but I know it's not worth fixing.  Do not pay 400 bucks for this.  You'll be very mad at yourself.  I'm looking for a new printer that prints directly on cd's.

Is like draft printing

color is dull.  Some horizontal lines in the image.  Printer settings standard (too simple), does not allow corrections

I got this machine because the toner is significantly less expensive on a cost per page basis vs my 9340cdw. I just assumed it would be the same print quality...boy, was I wrong. Terrible color, black is grayish, the whole image was pinkish, false contouring everywhere. Even the scanning was bad! Highly disappointed. Called to Brother and they couldn't remedy. What I found out was the 9340 uses newer LED technology and the 9550 uses old fashioned laser. Big difference!

I would have been one of the saps leaving 5-star feedback on this printer just after I bought it last November. Only now have I learned that Brother intentionally designed it to stop working after a few months. As others have noted, the color cartridges either dry up or just have sensors set to show them empty after a few months. I have almost never printed in color, but all three are showing as empty -- and it won't print B&W when the color cartridges are showing as empty. Brother chat support basically gave me a blank stare. This company cheated me on purpose. I will never again do business with it again.

This product fit nicely into the Brother MFC-9700 unit, however, the printer would not recognize it and would not print. We tried the seller's suggestions to make it work, to no avail. So, we had to switch out parts we knew would work from the old drum with those that would not from this one and essentially make our own new drum out of 2. But, the printer works now.

Will not output files to CMYK color format for a printing company.  Crazy!  If you wish to send your finished product to an outside printer via pdf, this software will not save the file in cmyk color  format for printing!  I had to trash this software and go back to my old Publisher 2010 which does save files in CMYK color format.  Why is Microsoft so lame???
