bn20 head soak unclogging dx7 printhead BN-20 Eco Solvent Printer **WORKS**

[@nichvo]

Hey, thanks this is the perfect video, I just bought a used bn-20 for ~500usd from an auction site thats been sitting for a year. Will pick it up tomorrow and clean it with this method. Seems like the most logical way. Cheers!

how did it go?

[@HassanDibani]

@@nichvo thanks for the update and best of luck.

thank you for making this video

I can not believe this, I had some clogged nozzles on the sign probably not even 10%, I did a couple of light cleans, which didn't make a lot of difference then did a heavy clean and had about 80% of the black nozzles blocked. This is obviously a manufacturing fault if you stay do not use the heavy clean… I will try your cleaning method and I'll let you know how it goes. New sub 🙂

[@reprint217]

Yeah I have another video on what typically happens to these dx7 heads. It's definitely a manufacturing issue.

[@RomanK87]

Hi friend, for BN20 if I'll need to change printhead, is it simple to put in new, or I need to program it somehow? What's the process?

[@itsjrj]

When you push the printhead over the capping station does it actually sit it the cleaning solution or is it right above it. I am asking because if you are able to move the printhead doesn't that mean it actually isn't touching the capping station?

Hey, Sorry, I have been in Atlanta at Printing United Trade Show. If still not resolved, shoot me an email. [e-mail]

Hi, I've some old heads that were blown from ink dropping into it that blew the trannies. had them replaced.. now I've mixed my blown heads with some good second hand heads. is there a way from testing the heads too see which are blown besides installing them and blowing transistors and fuses again. thx

[@reprint217]

Ouch, I literally was just going through my old dx7 heads and couldn't remember which ones were good and which ones were bad. Debating now if worth even messing with them as I myself definitely don't want to be causing any more issues. I would probably inspect connectors see if any traces of ink residue on blown heads. Its a gamble. Order some transistors and fuses and hope for the best I guess.

Thanks for the posts, extremely helpful. I have lost my entire light cyan head on my VS640i and some small sections on the light black, light magenta and yellow. head soak or head replacement?

Will this work the same for my SG 540? My cyan won’t get unclogged

[@reprint217]

I just created a video for you, so sorry for the delay! kzbin.info/www/bejne/pGfYfmCHYqljfsk

Hello, do you connect the lines back when you do the medium cleans?

[@reprint217]

Yes, lines need connected

[@mikeferretti7422]

On the print test shouldnt there be another yellow and magenta on the right side?

[@reprint217]

Depends on your ink configuration. The bn20 is white / metallic capable. This one had cleaner in it for one channel but some run dual magenta

[@reprint217]

The yellow was there but maybe hard to see

[@sarahspillane6985]

Hello, can you tell me if this will work on bn20a and if so. What is the liquid solution i should use?

[@reprint217]

You need some roland eco sol cleaner. Exact same process

[@AldrichQuaiHoi]

What about white and metallic ink clogs

[@reprint217]

Both White and metallic are manufactured differently than the cmyk inks and a much different animal. Typically, they turn back into a solid and impossible once they clog up.

[@franciscojoseburgosvillarr9793]

Very nice. I have the same problem. How many times did you soaked?

[@reprint217]

I do it often, depends on severity of head clog

[@lablount2910]

Thanks for the video, super helpful. I’m looking at buying a used one with this problem according to the listing. Do you know what I could look for when I go to buy it? Delaminating?

[@andreasvelbinger5160]

hello, do you have the pass for the roland service app?

[@reprint217]

They are specific to your serial number if you text me @217-413-2532 I'll help decode it

[@tosadan69]

sry to ask... i lost my blue nozzles on my bn 20 and i want to try this ... do you take power off while soaking?

[@reprint217]

Yes, you can unplug it during the process

[@dorothyramriez]
