Did you reset the drum counter?
When you replace the drum unit with a new one, you need to reset the drum unit counter by completing the following steps:

1. Turn the the machine's power switch back on.
2. Press Menu => Machine Info. => Reset Menu.
3. Press the Up or Down Arrow key to choose Drum.
4. Press OK.
5. Press 1 to reset the drum unit counter.
6. Press Stop/Exit.

I hope this helps.

Use a usb cable or connect through a wireless connection if MFC has such a capability.

Which Brother all-in-one printer or copier do you have? The LC61CL cartridges fit MFC-255CW, MFC-290C, MFC-295CN, MFC-490CW, MFC-495CW, MFC-5490CN, MFC-5890CN, MFC-5895CW, MFC-6490CW, MFC-790CW, MFC-795CW, MFC-990CW, MFC-J410w, MFC-J615W and the DCP-165C . The cartridges could fit other printers as well.

I know that the MFC_795CW has a cover on the right hand side that you need to open when the unit is on. Then the cartridge carrier will move to the ink changing area. (For a new printer, there is a green protector in place that you need to pull out. Keep this in case you move the printer later.) This location applies for the DCP-165C copier as well.

If the unit is on but the cartridge carrier does not move to the opening of the ink cartridge cover, then something may be blocking the carrier from moving. This could be a scrap of paper or other foreign object blocking the route.

Brother has the support for most of their printers available here: http://www.brother-usa.com/Support/ . There is a specific link for just the manuals on the page as well.

More complete trouble-shooting guides are available if you search for your model from the Brother search box at the top right hand corner of the page. Go to the product details page and then see the Brother Solution Center links on the right hand side of the page.

I hope this helps.

replace your cartridge with new one

Brother MFC 9180 change drum soon

your new drum should have had a plastic "starter sheet" installed just level with the exit hole. this sheet resets the counter, and should not be removed before fitting the new drum. The sheet will be automatically ejected when you have fitted new drum. If you still have this sheet it can be refitted to the drum, then reinstall the drum. Works for me ! MFC 9180

using the printer as standalone

Press every button on operation panel, I've known this model to get em stuck , please define if input is noticed in display and if mode switch ie fax, copy operates if key isn't stuck.
