Re: BN-20 dripping ink when performing perf/contour cut

Correct, but not only that, it also collects ink mist from the air around the print head and once the critical mass is achieved the ink drips on the media. This is when there are random and rare drips. Frequent dripping means a physical contact.

Re: ink channel not printing

If there’s still air in the line after choke cleaning there’s something wrong in the vacuum system, a leak or a crack.

Avoid choke cleaning at all cost. If possible, don’t do it.

9 out of 10 cases it's dirt somewhere in the print carriage.

Re: Bn-20 | Printhead healthy?

Your printhead is good.

Deflections can not come from the ink mist.

Check that your wiper is fresh and is installed correctly (blade pointing to the right).

Re: Bn-20 | Printhead healthy?

I don't know what you mean by dried attachments but if you are talking about the light drops on the left edge of the nozzle plate then these looks like cleaning fluid/ink mist. Should be wet, not dry.

It does but it's automatic, motor driven.

Re: Bn-20 | Printhead healthy?

This is a 97% perfect test print. What you see here is a feed calibration issue for the most part and a couple of slightly deflected nozzles. There are two passes of test print there and the dominant "thicker" part in the middle is the little overlap of the two passes.

Don't worry about it.

Re: Putting BN-20 into Storage

No, it's perfectly doable: 1) Order an ESL4-CL cleaning cartridge, it needs to be this particular one with blue stripes, not the all white cleaning cartridges supplied with the printer for ink filling. Also get a fresh waste ink tank. https://www.transfertpress.fr/images/Article/roland-cartouche-net...
