20 Most Recent Brother MFC 4800 All-In-One Laser Printer Questions & Answers

I use 'Photoscape' as my Samsung does not have auto-straightening. Photoscape is a free download. First load the scan into either MS PAINT or Photoscape and add generous white borders. Then load the bordered image into Photoscape and select the rotate symbol that looks like a curved arrow. Slide the control left or right until scanned image aligns with grid overlay. Then crop and save. You'll notice that as the image is rotated, it zooms in or out. This is why pre-made borders are added, to prevent cropping. Does this info help? Regards, Clive.

You can't do a reprint of the last fax it's not possible on any fax machine I'm aware of you'll need to contact whoever sent you the fax to resend

I've seen some of the Brother Laser printers develop problems with the thermal transfer rollers inside the back of the unit. Check to see if the rollers are intact.

Your fax machine uses the same line as your phone. You will need to read your manual to decide after how many rings you want the fax machine to answer. Generally should be after your answering machine. Your fax number will be your telephone number.Hope It's resolve all Your Printer Problem, Or Still having Problem Then follow Us For Brother Printer Support

If your printer does not have a duplex unit then the printercannot print double sided pages automatically.You can print double sided pages but you have to do it one page at a time.First print Page 1 then place the page back into the paper tray, but turn thepage upside down and the print Page 2.Then print page 3 on one side then page 4 on the other side and repeat for therest of the document.I suggest you try a test page first, to get the printing the right way up onboth sides of the page so it reads correctly.

Check your computer make sure its set on that printer. Then check toner cartridge, also unplug while still on then plug back in it should reset.

There should be three ports the phone line can plug into,
one will be occupied by the machines headset,
there should then be a LINE and an EXT port.

Make sure the phone cord is plugged into the LINE port.
If it is and still no dial tone try a different phone cord and also try hooking up a phone to the jack you're trying to plug the machine into to make sure it's live.

If a new cord doesn't work and a phone can get a dial tone then it's possible the board that has the jack could be bad and would need to be replaced by a service technician.

If it comes to that here's the part number you'll need to have replaced (you can try to google it to get an idea of the cost of the part, I suggest not trying to do the repair yourself and to actually take it to a repair shop though)

NCU PCB:
LG3190002

That usually means you need to replace the image drum or the corona wire or fusor It can also be a toner cartridge problem.

None of these are hard to do but they can be pricey for the image drum.
If you just replaced a toner or use a non oem replacement it could cause this. If you print say 10 pages and it fades out then I would look at replaceing the toner cartridge even if new. There is a brush or scraper than collects the extra toner and when this wears on refils or isn;t as good on off bands then you can get this.

Return both and get a fresh batch. You could have gotten a bad drum or toner. But first take out the toner and get her a good shake just to loosen it up if there are any clumps or jams

Hi mp133, If the main goal is for your All-in-One Printer to communicate with your computer, the most common set-up is to use a USB Cable. Plug the phone line to your All-in-one-printer and then just connect a USB cable from your printer to your computer. I hope this helps. All the best to you. Good luck.

First of all, restart your system and your printer. Leave the printer off for few minutes (let the printer get cooled) and then reconnect it's usb cable and try giving a print command. If the problem persists, uninstall it's drivers and reinstall it. It'll be helpful if you update it's driver.

It's also important to run a registry cleaner and system cleaner.

If you have further problem, do let me know with the description of the outcome from the above tips.

Good luck.

Thanks for using FixYa.

This could indicate that your "paper size" setting is not correct for the paper you are using or the "reduction" setting may not be correct.

Brother support suggests that the "Reduction" value be set to "Auto Reduction" = ON

To set "Auto Reduction" to ON:

1) Press the <Menu/Set> key
2) Navigate up or down to "Fax" - press <Menu/Set>
3) Navigate up or down to "Setup Receive" - press <Menu/Set>
4) Navigate up or down to "Auto Reduction" - press <Menu/Set>
5) Navigate up or down until "ON" appears - press <Menu/Set>
6) Press <Stop/Exit> to return to normal function

I hope this will help with your extra received page problem.

Hi seen this bit on the net you can gave it a go.


Power off the printer for 15 minutes and power back on again. If that fixes the problem then OK.
If not then go into maintenance mode -
Press and hold the menu/set key while turning on the machine. Wait until it comes completely up before releasing. It should say Maintenance in the display.

If not press function,*,2,8,6,4 within two seconds. It should say maintenance in the display. Or on some machines Menu,*,2,8,6,4 within 2 seconds.

Once you get it into maintenance hit 91 to do a parameter reset and than 99 to get out of maintenance.

If this corrects the problem then OK but you may have a failing thermister in the fuser.
If the problem happens again then change the thermister.

If the reset does not work then either the thermister or the fuser lamp has failed. In rare cases there is a poor connection with the cables to the fuser.

You will have to reset the parameter again after replacing the fuser if you need to replace the fuser or repair it.
