Help - removing wrong ink from Roland vp 540

Hi everyone,

I inserted a new magenta ink only to realize later that it was in fact a light magenta ink & it has totally ruined my color profiles. Black is printing dark green etc.

I replaced the cartridge with a normal & correct magenta cartridge, have done several normal, medium & powerful cleans. Still not printing correctly.

Any idea how many cleans it's going to take & also is there any harm in doing lots of powerful cleans? I have also sucked ink through with a syringe - still no improvement. I am trying to avoid flushing.

Thanks

Yolanda

It seems that you will have to completly flush the system and as far as powerful cleans go some will say never preform them others say they are no harm, I had a similar problem a while ago, for some reason my cyan head was printing black all of a sudden and I didnt even change inks but after a lot of powerful cleans it was back to normal and never occured again. I would try to draw the ink out with a syringe again and if that fails then just flush it.

Powerful cleanings will flush ink but you mostly waste ink. It will flush the ink from the cartridges to the head. Lots of wasted ink there and it is not color selective!

Perform a pump up from the maintenance menu and then flush the line with a cleaning cartridge. Reset the cartridges and you should be good.

Maybe I am missing something. You used a light magenta instead of a magenta. it is the same family so I think you are getting that result for another reason. Lets clear the record - Powerful cleans will never harm your machine - roland would never set you up for failure. Powerful cleans waste ink - period and there is not guarantee it will get the failure corrected. So you have a VP540 - a powerful clean on your machine clears ink from cartridge through to the printhead - so if you done one of those then you would think you cleared your issue. You also done a normal clean - flushes your head, a medium clean - flushes your dampers all producing the same result. As Steve stated the machine cleans are indiscriminating so it is cleaning all lines to include the ones not needed. I am in favor of isolation -so the syringe method is the way to go here but you did that - so I think it is time to look elsewhere. My recommendation is to print a nozzle test and a machine test print - post those results and I will be in a better position to tell you what is going on. Steve will also.

But which palette are you using to create your design. I think your issue is more with the color management than with your ink. So I will wait for the test results.

Hi Everyone,

Thanks for all the replies :)

Yip the light magenta turned my black into dark forest green & my red into orange etc. After doing several cleans ( bout 10 normal, 10 medium & yes! 10 powerful ) and still getting the same result I took a syringe & removed about 80ml of magenta ink - yikes! Then did one normal clean & all was back to normal straight away! Think I removed too little ink the first time round & that's why it didn't make a difference.
