| I see there are no posts on Brother's 5440/5840CN series. My magenta will not print after multiple cleaning cycles. It sounds like I must physically clean the head or replace them. Has anyone done this or have a repair manual I can look at? Thanks in advance.|

|You are correct. Your printhead or ink loader assy needs replacement. Contact a Brother ealer about a printhead replacement....unless under warranty, you'll find its just not worth it in most cases.|
Have you been using Brother Brand Ink? I've seen most generics inkis fail and foul this printer.

| Does anyone have a schematic that shows how to remove the heads? If the machine is no good now, it is worth a try to flush the old heads with alcohol and see if it clears up. No?|

You cant clean a permanent print head outside by soaking it into some fluid (alc or whatsoever)!
The brother ph are cleaned by the power purge procedure (maintenance mode -> 7 - 6 - 3).
If you have done so and your magenta or other color wont work the color channel is defective or the nozzels are rotten or the membran is rotten.
You need a new ph!

| O.K. Thanks. How does one remove the head so they can flush out the system? Are there any schematics out there? Easy explanations?|

|Go into the maintenance mode (menu,*,2,8,6,4) and do the power purge procedure outlined above.|

| Anyone know what a print head costs? Labor will be free[er] if I do it, what about parts? Ball park is all I am looking for. Thanks.|

I have the same problem and am following your advice (thanks!). Don't know if I'm doing it right though. After pressing 7-6-3 the fax, scan, copy and photo capture buttons are all flashing - and have been for some time. Not sure what to do next. Is this right? How do I know when it's finished? Can you help? Thanks.

|Did you ever figure out how to work maintenance mode?|
|Re: Re: Re: Re: Brother MFC 5840 CN print heads by Anonymous (4/27/09 7:58 AM) reply|| + / -|
|The first method suggested (menu,*,2,8,6,4) did not work for me. This is what did:|
- SWITCH OFF PRINTER WHILE HOLDING DOWN MENU BUTTON
– SWITCH PRINTER BACK ON WHILE STILL HOLDING BUTTON DOWN
PRINTER WILL BE IN MAINTENANCE MODE.

|How much is a print head. My black is not working.|

|I got into maint mode, but could not get out, or power flush the cartridges. Any suggestions?|

|The trick to get into maintenance mode is to press Menu-2-8-6-4 quickly like|
dialing a phone number, in less than 2 seconds.
Dial 9-9 to get out of maintenance mode when finished.
Some operations in maintenance mode:
7-6-3 (power purge mode), then press "black start" to begin purge
01 (erase all eeprom data including user programming - total reset operation)
91 (erase most eeprom data excluding user programming - partial reset)
You can also clean the print head well using the Ink - test print quality - menu choices in normal mode. You can repeat testing and cleaning by following the menu prompts. It might take 5 or more operations to clean the print heads. For some reason it seemed for me that cleaning all the heads- black and color - worked better than just cleaning the black head.

|Do not give up on using the power purge to clean the head. It took me forever to get ink to flow. Just keep going through the purge cycle.Somewhat of a waste of ink but it did work for me.|

|I agree with wpollok, don't give up ,it took me at least 40-50 purge cycles(and test prints in between) and finally ta ta!|

|Before the printer used to say that it could not clean I followed the suggestions and it worked. I tried to disassemble the printer and clean the ink tray but was unable too. So I just reset the number. Now even though there is a brand new black ink cartridge it does not print in black. but the other colors do.? Any suggestions?|

I am trying to change the ink and now it says that there is not a ink cartridge in there and it is. HELP!
