Customer Question

I have a brother MFC-5460cn printer. In the last couple of days I have not been able to print due to a error message which reads: PRINT UNABLE 4F. The message says to refer to Troubleshooting & maintenance chapter in users guide. I have gone through that chapter & performed the cleaning steps in addition to unplugging the unit for several minutes. I still have the message. Please help me. Is there something more I need to do. I can't reset the unit. What does the 4F refer to?

Open the cover and remove the cartridges close the cover and unplug the power for 5 mins.

let me know once done we will proceed with the troubleshooting steps after 5 mins.

I assume you mean the ink cartridges. Is that correct?

I removed them at 11:38pm. No need to direct connect.

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, and then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is ***** 6000, enter 2 7 8 3.

This will reset the purge count value. Then the printer will restart, hopefully without the annoying cannot clean message.

This happens because of using compatible ink cartridges try to use the printer with genuine ink cartridges.

When I press the Menu button, it goes to general setup & when I press a number it beeps & moves to set up for telephone ring answer & will not accept any other numbers
Customer: replied 5 months ago.
Are you still there?
Expert:  Michelle replied 5 months ago.

do you have a "Set" button on the printer?

Customer: replied 5 months ago.
No, the print has only a Menu button
Customer: replied 5 months ago.
Is there another button that serves as a set button?
Expert:  Michelle replied 5 months ago.

Disconnect the Brother machine from the poweroutlet.
Open the scanner cover.

Check the print head's position.

The print head is positioned at the left hand side of the platen area or on the right?

Customer: replied 5 months ago.
I am not sure what the platen area is. When I raise the Scanner cover the bar is on the left & moves to the right as it scans a sheet. I don't see what I would think of being the printer head
Expert:  Michelle replied 5 months ago.

the flat area where the head moves.
