jay,
close to the facts:
never(!!!!) clean a brother printhead by soaking it into a solution what so ever it contains!
The printhead is a piezo one and totally diffrent from hp or canon bubblejet which heats the ink to print while the brother (and epson) ones have a bi-metal insides which "fires" ink onto paper when needed. The outward cleaning solution will destroy the bimetal and the electric inside the built-in-one printhead.
Do use only dye ink for brother printers. In fact there is a filter inside the printhead in front of the nozzels. pigmented ink has particles (which give the color to the "water" where dye ink is already "colored water" without partikles!) which definitley cloggs the filter and therefor the nozzels! The filter cant be cleaned because its part of the printhead.
The machine has a counter built in which counts the cleaning cycles of the machine. There are small clying cycles which the machine does by start printing (some 0.5 ml will be waisted) and the manual cleaning cycle started by user which needs a 3ml amount of ink.
The machine has a built in waistinktank like all inkjet printers have. The engineers of brother have set the counter to an amount of taking up cleaning ink that will last for 2.5 - 3 years in normal use (and using original ink!). When the waistinktank has taken up the max of ink the machine will display error:cleaning and refuses to print anymore. The tank has to be replaced and the error (error 46/error:cleaning) has to be deleted within the eeprom.
Some solutions:
Run the cleaning cycle twice with original brother ink carts placed in the printer.
If you are lucky the nozzels (or filter) will be trouble free again.
If you dont see any success the printhead (or partially the filter) is clogged and has to be replaced by a new one.
Do use only (empty) original ink carts with a refill dye ink. Mix it up (:-)) with a trace of printhead cleaning solution by 1:10 for the C/Y/M colors only. You can refill an amount of 11 ml (1 ml cleaning solution + 10 ml ink) into the C/Y/M ones and an ink-only of 20 ml into the bk one.
In case the waistinktank is filled up and error sign appears search the forum here for error 46 and buy a new waistinktank as a spare part from a service dealer.
