Colour cartridges full but not printing
I've been using this Brother MFC for some time and I've been quite happy with it.
About a year ago I noticed that colour images would only print black and white.
My settings are to full colour. The cartridges are full and in good condition according to the ink refill place.
Not sure what else is going wrong.
Actually, I updated the question to reflect the proper model is all.
I regularly hear the printer doing the automatic head cleaning.
I just wonder if it's possible to submerge those bits in rubbing alcohol or some other non-water source to remove clogs/build up.
Это хороший вопрос?
Have you tried printing a colour copy of a page, by loading a page with colours on it into the printer, using the copy function on the printer itself and pressing Color Start? Does it come out B/W or Colour? If colour is printed then at least it proves that your printer can still print in colour, which is a start to finding out what's wrong.
Colour simply does not work. It's not a file transfer issue from the computer. Using the colour copy setting will not do anything either. I'm curious what I may need to clean to get the ink to flow out from the tanks.
Also, mine is 250c not 240c
Sorry about thinking it was 240c I can only surmise, like you, that the printhead has become clogged with dried ink due to not using colour that often. The cost of replacing the printhead exceeds the cost of a new printer. I can only relate to you my experience with my Brother mfc 440cn which had the same problem, not as bad, would not print magenta or yellow. I ended up doing a printhead clean operation 7 times, which I know is wasteful of ink, but I couldn't print red or yellow anyway and their cartridges were full (you can select colour as a clean option so you don't waste black). It worked, although I had to do it one more time as the yellow was still intermittent. I have since worked out how to prevent this problem, if you do not print in colour that often. Leave the machine in sleep mode. I found that it would "wake up" every so often and do a quick printhead clean then go back to sleep. I hardly print in colour but for over 3 years now have not had a problem. I am using generic brand ink refills
According to my experience with the MFC-240, I can fully support what jayeff just said.
If his recommendation does not work out there are still two more options. First, you may start a power purge (cleaning) procedure, using the printer's "service mode". I could send you the instructions how to activate this in case you need it. It is not complicated, just a strict procedure of steps you have to follow.
The next option is to open and disassemble the printer and to clean the print head with distilled water. I did it, and it helped. However, for doing so, you need a service manual for the MFC-240, and quite a bit of courage ;)
