Need Help Print problem Roland BN-20

[adamfromayr]

The market is flooded with Chinese Parts like 1/8 of the price of an OEM one but like many fakes they are just not reliable enough

Here's a source for a good captop:

https://www.solventinkjet.com/product-page/dx5-dx7-cap-top-for-use-in-roland-printers

It is 3rd party, but these guys are techs and dealers and they rigorously test the aftermarket parts they sell. Probably the only place online I would trust 3rd party parts. I have always bought my dampers here, as well.

If it's from DIGIPRINT, it's most likely 3rd party and not OEM. Especially if it's in that kit, they are all 3rd party parts, at least all the ones I've bought in the past from them for our printers.

Hello, after checking with DIGIPRINT, they confirmed that the cap top of the kit is OEM and not a generic.

 

[sekorse]

Hello, I ordered OEM dampers and a new OEM cap top, do you have any advice before installation? Thanks

 

[Jim Hancock]

Just this... Not just DX7 dampers, but ALL dampers.

 

[sekorse]

Thank you, And do you have a tip for finding out if there's still an air leak in the duct, please? Thanks

 

[Jim Hancock]

I'm presuming you will do a power clean to charge the dampers. There are only 2 ways I can think of with the DX7 heads. One, while it is pulling ink (when the head is over the capping station), which for any air bubbles in the ink lines. I would shine a bright light on the lines at the print head to watch for them. The bright light will make everything more visible. Two, when the head moves over to clear the cap, quickly look at the ink in the cap and see if you can see any bubbles in the ink. You shouldn't see any.

Hello, I just installed OEM dampers, for the moment the yellow is back to 75% (I have the left line half empty), despite several cleanings it does not change anything ... I have a new OEM cap top and a non-OEM pump here do you think I should install them?

 

[damonCA21]

Yes you need to install the OEM cap top. The pump seems to be working fine as it is cleaning the other colours fine. The yellow head is probably clogged from sitting now, so you need a cap top that is working correctly

 

[sekorse]

Thanks I'll try to install the cap top... and the pump anyway I received broken I just saw that an ink inlet is broken

 

[sekorse]

Hello, after changing the captop I still have the same problem, I do not understand where it can come from everything is new.

 

[damonCA21]

Is the test print still looking the same? Run a couple of powerful cleans and see if it changes at all

 

[sekorse]

Hello, I've cleaned up but there aren't many more nozzles, some disappear, some appear, I tried a yellow print and the beginning didn't print for 4cm, then the yellow appeared but still with lines due to the missing nozzles...

 

[sekorse]

I also tried soaking the head overnight before cleaning this morning.

 

[sekorse]

It worked for 2 meters, then the yellow completely disappeared for 15cm, then came back little by little...

 

[cornholio]

Still on Max3 ink?

 

[sekorse]

Yes always, to tell the truth the Max2 is out of stock in France... I don't know if it will come back.

 

[sekorse]

Hi, do you know how to switch back to max2 ink, as I'm still having yellow problems despite changing all the parts... and I still have max 3 cartridges installed for the moment.
