Replaced black ink cartridge, but now it only prints a very faint line, cant make out what is printing


Sir/Madam

If your printed pages have a horizontal line in the text or graphics (as shown in the illustration below) or blank text, some of the nozzles may be clogged and need to be cleaned

  • If the print quality on the first Check Sheet matched Example (A) or (B) and you do not see any improvement on the second or third Check Sheet, please contact Brother Customer Service from "Contact Us."

  • If the print quality on the first Check Sheet matched Example (A) or (B) and you see some improvement on the second or third Check Sheet but it's not perfect, repeat the cleaning and the quality check process three more times (totally five times).

    Sir, I hav canon ip1880 pixma. I have already refilled the black cartridge and is working fine. my question is that can I refill the colour cartridge with black ink in all its three compartments instead...


    I would not advise doing that. Once you do this you could have unexpected poor print quality.
    If you only want to print black documents then I suggest you purchase a laser printer, these printers are not expensive now and the cost to per page is cheaper than inkjet printers and they do not suffer from block inkjet nozzles.

    We have a HP Colour Laser Jet 3600n. We have


    nope...... the problem as you rightly poit out is the cartridges, most refills are poor quality and dont last, but the real ones are expensive but very rarely cause issues. If one colour is dodgy the entire colour process fails, print a square of each colour to determine which colour cart is the issue and complain to seller, 99.9% of print quality issues with these HP's is due to non gen toner....not much you can do, expensive is colour printer fullstop.

    Epson aculaser c1900 error code e014


    Error code 014 indicates that the cooling fan on the power supply board is not operating when the printer is switched on. Does n't explain the poor print quality though. I suspect it is a worn 2nd BTR roller (the black foam coloured roller inside the rear door). To check this send a coloured print through and press hard against the rear door during printing. If the print quality improves then it is a worn roller, if it doesn't let us know and we'll try something else.

    Please take a moment to rate this solution. Thanks.

    6. Closely examine the print quality of the four color blocks that are formed by short diagonal lines on the Test Sheet.
      If all lines are clear and visible, press 1 (YES) and press Stop/Exit.
      If you can see missing short lines, press 2 (NO) and go to Step 7.
    7. The display will then ask you if the print quality is OK for black and three colors. Press 2 (NO) for black or three colors with the problem.
    8. The display will then show START CLEANING? 1.YES 2. NO.

    10. If you can see missing short lines in any of the four color blocks press 2 (NO) and repeat the quality check and cleaning process. Repeat this procedure at least 5 times if print quality remains a problem. If short lines are still missing after the fifth cleaning and test print, replace the necessary ink cartridges.
