Hi all any help will be appreciatedI've had my bn20 from brand new for around 16 months all works perfect apart from issues with white, I have to do a few cleans and the white comes through and all's…Continue
"Thanks for the advice
Soon as I put the new cap station on it all worked and even the white has come back. Massive load off my mind
So there is no need to flush after all
One thing to mention the copy cap station had caused the problem as it never…"
"That is the first step, the visual looking to see ink going into the dampers
Next, use a syringe from the pharmacy and pull from under the top until you get movement in all the lines
If neither of those work, then you have to think a failed damper"
"So my summery is that the original cap top was 16 months old and clogged too much to draw the white but ok for the other CMYK. The copy cap top caused the blockage and putting the old cap top back on was not good enough to pull the blockage…"
"Go through the procedure, but it will not help. The reason why I say that is that it is a uni captop and it cannot affect one channel totally. If top was failing, it would be across multiple channels (columns). The flushing might help move the air,…"
"Thanks for the reply irving
I was told to flush it through the roland utility like the way you put in the dummy cartridges and flush each one as it won't let you do just the one
I have a gut feeling it is blocked above the head poss the dampers…"
"So how were you told to flush it? U cannot properly use the machine with the channel missing, for if it needed it and it is not there you will have banding. With that said, if a complete channel is missing, you first check for air - larger machines…"
"Well I could not disagree more, maybe I could. You have perfect nozzles in all but one channel and they say flush the whole system. With the BN20 you have a user level flush that you do not have with the larger machines, so that a good thing because…"
"I have been advised by my supplier who has spoken to roland that I should flush out all the ink I have ordered the blanks and cleaning cartridge . If that does not work it's possible the dampers or the print head. I just can't understand…"
"Excellent - so check your hoses. If you have a blockage (usually T connector) it will blow a hose off and leak ink into the machine. Also good to check the connector as magenta is a known clogger in certain environments. At times you have to snip…"
