Mfc-j270w prints blank pages and cartridges are good, tried cleaning procedure several times

SOURCE: I have a Brother MFC-5840CN

Tech support at Brother could not help me over the phone or via the net so I figured I would get the same info from you guys and have to pay for it and still have a printer that doesn't work so I will take it to the shop and pay them only if they fix it
Thanks

If cleaning doesn't work you should talk to your retailer or Brothers support. Don't think they can expect you to use up all ink cleaning cartridges when the machine is straight out of the box..

We are going to attempt to do a "power purge" to get rid of any clogged ink nozzles. Note, this will probably eat up about half of your ink, but that is the price you must pay in order to attempt to fix this bad boy.

1) Get into maintenance mode. Press these keys: Menu -> Black Start -> Scan x4 (hit it four times). A number pad should come up. If not, do it again.

2) Hit key 7, then key 6.

3) Press the right key until you get to "CLEANING BLACK."

4) Press 3.

5) Press Black Start.

After it purges and gets back to the main maintenance screen, press keys 9 and 9.

Let your printer start back up. If this does not work, try the above steps up to three times. If it does not work then, you need a new print head, which is not a user-replaceable part on this model.

Good luck.

You may need to clean the printhead: (make sure you have paper in the tray)

1) Press <Menu>

2) Press <Up> or <Down> arrow to select "Ink" then press <OK>

3) Press <Up> or <Down> arrow to select "Test print" then press <OK>

4) Press <Up> or <Down> arrow to select "Print quality" then press <OK>

5) Press the <Color Start> button. The quality test sheet will be printed. Check this printout for gaps in any of the colors or black in the pattern across the page.

6) The display on the printer will ask if the print quality is OK:

- If all lines are clear and visible, select "Yes"

- If gaps appear in the pattern, select "No"

7) If you select "No" the display asks (in turn) if the print quality is OK for black, and the three colors.

Respond "Yes" or "No" accordingly. (In this manner you may clean just the black or color nozzle that is giving you the problem)

8) The display asks if you want to start cleaning - choose "Yes"

9) After cleaning is finished press the <Color Start> button - the print quality sheet will print again.

At this point you may determine that another cleaning cycle is necessary. You may need to repeat cleanings (up to five times) to resolve the problem. Any more than that indicates a problem that may need brother customer support.

10) When the print quality test sheet meets with your approval, you may exit by pressing <Stop/Exit>
