Hi. I have a Brother 340CW printer. Recently the cyan wont print or it is restricted. I used all the print cleaning and alignment functions about 10 or so times but it hasn't seemed to have worked at all. I replaced the affected ink cartridge and reran all the cleaning but it still wont print cyan.
That is it's similar to HP/Canon where the print heads are incorporated in the cartridge, there are but two possibilities. 1. The contact strip in the Cart chamber- that makes contact with the ink cartridge is damaged or dirty-remedy is to clean it gently and endure by close inspection that it is not damaged or distorted. or 2 The printer software is corrupted in some way. remedy - remove and reinstall per the instruction.
The ink cartriges are separate from the print head and are individual. They have little hoses that take the ink to the print head. I have had a look inside the printer and have no idea how to get the print head off its rails without breaking it. I wanted to see the underside of it to clean the heads with alcohol.
The only other option I can see is to use an empty cartridge, fill it with alcohol and run the cleaning cycle until the alcohol gets through to the print head. I'm assuming that the head isn't completely blocked and will allow the alcohol through to cleanse it in the process.
