Light blueprints instead of black
Light blueprints instead of black
Hello there
I own an old MFC j4510dw printer that had issues with paper feeding over time. After replacing the rollers, it started working normally, but now it prints a light blue color instead of black, even when copying and not connected to a computer. I believe it was good to note that a few months ago it had sufficient black ink, but now it shows the black ink is depleted. When I tried to test it, it reported that the black ink was out. I replaced the cartridge, but it still prints light blue. The printer brand is MFC J45 10 DW.

The printer offers a method to print a Test Page – refer to page 98. This produces a pattern of ink spots for each of the four colours. I wonder if this yields satisfactory colour blobs for all three colours and poor results only for black? I question your concern since you mention black doesn't work, yet it appears blue. Perhaps this is due to the combination of colours but not quite black. However, if the three colours don’t come out well, a different approach may be necessary.
The procedure is outlined on the previous page, 97. You have three choices: if the issue is solely with black ink, perform Black Only cleaning. If black is acceptable but other colours are poor, try Colour Only. Should problems affect both black and another colour, opt for All. You may print a test page after each cleaning to verify, or continue several times. The guidelines suggest replacing the ink cartridge for the faulty colour after five cleanings if the problem persists. But if you're confident ink remains in the cartridge, you might skip changing it and simply repeat the process up to five more times.
Should even that not resolve the issue, there may be a deeper problem—possibly very dry or hard ink inside the print head. Additional cleaning cycles are unlikely to fix this. You could wait a day and retry, but at that stage, it's recommended to contact Brother's Tech Support for further assistance.
Online tutorials exist for using a head cleaning kit with a syringe and special solution to improve cleaning, though they require more complex handling of the printer. If you're comfortable with DIY repairs, you might find it worthwhile. I've had printers where I could actually remove the print head (it was designed for replacement), soak the jets to dissolve the ink crust, and reinstall. I don't believe this is possible with this model, but their Tech Support team can advise further.
