MFC-J3530DW | MFC-J6530DW | MFC-J6730DW | Maintenance Mode | Head cleaning

This operation is recommended when the standard cleaning of the print head (from the maintenance menu-as I explained below) has no effect.It is also possible to work on other Brother printer models.
76 ---purge operation/ cleaning: (use in bad print)
0---head replacement
1---single purge
2---normal purge
3---power purge
4---initial init
Note: 0 & 4 is very consumable in ink !
Standard operation:
1-Press [Ink]-[Print Head Cleaning].You can also press [Settings]-[Maintenance]-[Print Head Cleaning].
2-Press [Black only], [Colour only], or [All].
3-Press [Normal],[Strong], or [Strongest].
4-Press [Start]. The machine cleans the print head.
