Question about Brother MFC 6490CW InkJet Printer
It sounds like your print head is clogged.
Try this on the cartridge.
01. Hot, but not boiling water.
02. Hot, but not boiling 50% - 50% mixture of Ammonia & water.
01 + 02: Hold Printhead - Only - in hot water or mixture for 12 - 15 seconds. Using a paper towel, firmly hold Printhead vertically onto paper towel as to where ink will "Wick" into paper towel. This may be done several times.
For very stubborn colgs, Printhead may be soaked overnight.
* Be very careful of your Printhead - even "Wiping" Printhead with paper towel can cause damage to Printhead - it doesn't take much.
03. Using a cotton Q-Tip & Isopropyl Alcohol [99% is best - 91% would work - if nothing else is avaliable, 87%], GENTLY rub the Printhead with Alcohol - this may be tried several times.
