How to fix the DCP-6690CW unable to clean 46 error

Purge Counter Reset Instructions Please note that some of the terms used below to describe buttons may change from one printer to another. For example:

• START may be down as MENU or SET on your printer or be a green button
• STOP may be referred to as EXIT or a red button

Before you begin the reset procedure your Brother inkjet printer needs to be in maintenance mode, but depending upon the model of your printer the method of doing this will vary. For most modern Brother printers please try the following:

1. With the printer turned on and ready to print remove the power cable from the printer (or turn the printer off if you have a fixed power cable).
2. Hold down MENU/SET/START and re-insert the power cable/turn it back on.
3. Keep the button held down until the screen reads MAINTENANCE.

If your screen does not now say MAINTENANCE it will need to be put into maintenance mode using one of the two methods below:

• Printers with a built-in Fax: Hold down MENU/SET/START and quickly press * 2 8 6 4.
• Printers WITHOUT a Fax: Hold down Menu/Set and the Black Start key before pressing the UP arrow four times.

Now your printer should say MAINTENANCE on the screen and you are ready to begin the process of actually resetting the purge counter.

1. Type in 80 using the numerical keypad.
2. Use the DOWN key to locate the purge counter. eg. PURGE0060025
3. Use the number pad to enter 2783 (this should zero the numbers after PURGE).
4. Press STOP/EXIT to return to the first stage of maintenance mode.
5. Press 9 and 9 to exit maintenance mode.

Your purge counter is now reset and you can now resume printing as normal. If however this has not cleared the error message I advise going through this guide again following the instructions to the letter. If the error persists please let us know.
