    Hi Guys!

    I have the issue of Magenta color doesnt come out as per normal. It looks like there is clogging.
    The first picture was taken when i first spot it on Wednesday, 19 Jun 2019.

    The second picture was taken after I have done these steps:
    - Normal cleaning
    - Medium cleaning
    - Powerful cleaning
    - Manual cleaning
    - Head soak overnight
    - Light choke cleaning

    For your information, recently we have changed
    - The printhead on 6 Aug 2018
    - 1 of Magenta ink damper on 19 Oct 2018
    - Wiper head (black) on 21 Jun 2019
    - Wiper head felt on 21 Jun 2019

    The only thing we have not changed is the Captop. My machine is Roland VS-540i.

    Appreciate any inputs for me to solve this.

    Great day ahead!

    why change the damper so soon after changing the head, presume std inks as a rule if changing the head renew all bits that touch it at the same time.


    think you may have answered it at the end, all the cleanings in the world will not help if the cap top is not sealing, around 12mth change on a 8 colour earlier with white met inks.
    also the felt sponge in the capping gets clogged with ink particles and does not suck as well, from experience only use the genuine ones yes i know they are 5 times the price of aftermarket but do seal better.

    Thank you for the respons.
    We changed the damper because we didnt change it during the print head changed. Magenta color starts to leak only after about 2 months later.

    I meantioning the Cap Top after i did a search on the forum. Some did solve the problem other not. So im asking here again to see if there is anything that i missed out.

    I told my supplier about replacing the Cap Top but he said maybe the printhead or the damper. I would prefer to change the cap top then damper or printhead since cap top is cheaper

    So hopefully i get the inputs from forumer before he coming over on Monday

    [​IMG]Hi everyone,

    Just to update that this is the latest test print.
    - After changing original Cap top
    - Soaking printhead for more than 48hrs

    - Normal cleaning 4x

    - Medium cleaning 1x

    - Test print.

    Is this mean that I need to have a printhead change?

    Thank you in advance!

    I'd flush the magenta channels before trying anew head. It can damage the head but it's worth a shot as a last resort. A lot of the time it just flushes out and you are good to go especially on younger heads like yours.

    I normally use a tapered syringe and hook a piece of solvent resistant tube onto it. Then just attach the tube to the manifold where the damper normally connects to the head. I push cleaning solution through gently at first until it sort of bubble out of the nozzles and then push harder until it sprays out like a waterfall. Don't push any harder than that. You will actually be able to see the nozzles that aren't firing in the stream. As solution flows through, you might see those nozzles start to spray again. If you can get them all to spray again, the nozzle check should come back 100% unless, as I stated above, you damage the inside of the head which is a possibility so only do it as a last resort. In my experience it doesn't happen a lot but enough to want to be sure about it.
