Question about Brother MFC-9840CDW Laser Printer

1 Answer

I have a Brother lazer printer MFC 9840 cdw. I have had it for 1 year. Recently I have noticed that when I print, there are black dots or ink marks on the page, usually 3 or 4 in a straight line spaced out. Also, there is a red line on the edge of the paper.

You can try ordering a cleaning kit or use rubbing alcohol and cotton swab on the contacts, toner, and heads.

Why brother mfc 7360n printing envelopes wrinkle paper


Do U mean wrinkle the envelopes?,,,,I can solve some MFC-9840-CDW issues, but the 7369N is a guess. Read your manual or do a google search.....There maybe a setting in the 7360N that adjusts printing for card stock and envelopes....

I have a all in one color LC61 printer, do all colors have to be filled to print blk only?


Greyscale is color not black only.
You can print in black and it will look grayscale only darker, printers are a pain to work with after a year has gone by, I can expect almost a half hour to print something with my $400 epson because one of the colors is out even though I never printed in the last year a colored page. I take the color cartirges out and they are empty, but I only print a page 2-3 times a year. I use the scanner all the time. Brother and epson have their print heads in the printer not the cartridge so make sure your inks are always have something in it or it will be miricle for the printer to last more than a year. Check colors every other week. One Epson printer only lasted 3 months because I never used it(print head dried up). Never use the set up with tubes running outside printer to small tanks of ink if you only use it occationally.

Hi,
The first thing i would try to do is clean the corona wire on the drum unit. It might also be a faulty magenta cartridge.
