GREAT, SAVED A LOT OF MY TIME. I NEEDED TO FIX USB PORT ON THIS PRINTER. THANKS

[@charlietodd2867]

I started my disassembly with a page that fades on the right side. I used this guide to get all the way to the laser assembly where I did a full clean. I was not successful in fixing the faded page, although it's better.
But, most importantly, I got the printer apart and back together again thanks to your video. No broken tabs, snapped wires, or lost screws. At a few points, I felt like I was completely stuck only to watch you put a small screwdriver in just the right place to release a tab.
Thank you for the video and the time you spent getting a clear shot.

Welcome...Just try replacing the toner cartridge or drum unit for faded page.

Awesome vid. Helps to follow with Service Manual. I have "paper jam inside" msg with no paper jam. Service mode told me code 7000. I went to sensor check mode and all sensors work except the Front Registration. So it thinks there is paper at the front registration switch. I'm trying to get to the registration assembly. Service Manual flow chart says to just remove right cover and then High voltage PCB. But in the pictures there is a lot more removed before pulling the main frame R assembly. How do I get to the registration lever and make sure it is hooked up?

[@macor285]

Thats good. Congrats...

[@bluedrew]

No congrats yet! How do I get to registration assembly??? Do I need to remove the L frame and then R frame? I can remove the screw holding the assembly, but it is underneath another piece lodged between both frames?

Hi, can you tell me if in these kind of machines the document scanner unit is the same part that scan when using the document feeder? Mine doesn't do double sided scan anymore and I found the document scanner but I am not sure it's the part I am supposed to replace.

[@macor285]

Still can copy/print 2 sided? If yes, try to updatw scanner driver.

[@ChristianBrandoni]

@@macor285 I am scanning from the printer itself to the web and it still does it.

Hi, I have model 2710DW and I had paper error 09 I watched other video of how replace the plastic part that check the drawer in, but it was different from the video I saw and now I have all the gears disassembled is there a way to figure each gear where it goes or do you have a video for that?
Thanks,

[@macor285]

I don't video for that model. You need to download the service manual www.manualslib.com/manual/1582425/Brother-Dcp-7090.html#manual

QQ: we were printing on a 2700 this morning and it died. We tried the reset (unplug, hold the on switch and plug back in) but no luck. Is the PCB (LV1321001) the item likely that needs to be replaced?

[@macor285]

Check the power supply. If there is power and printer is not responding then mainboard needs to be replaced.

[@rebeccajean1309]

@@macor285 Thanks. There appears to be 2 power boards. The longer one where the power comes into the printer. Yes. There's voltage where the AC cord comes in.
