The nozzle test shows a lot of missing or deflected nozzles on the black channels, this is likely causing the misting when printing, start with manual cleans and then a couple of medium/normal cleans to see if it improves the output, failing that contact your local Roland office to get an engineer to visit.

I did medium cleaning, normal cleaning, then medium cleaning, normal cleaning. I've done manual cleaning yesterday. Here's the result.

Some improvement has seen on the printed sample, but still has some mist. Hoping it will gone by repeating the cleaning process..

It looks like it's all over the black as well, I would get an engineer to have a look at the machine, they can better determine what is going on with the head.

Thank you sir! I will probably go to the nearest service center.

Someone told me that mist on the print area is cause by head height, can i manually adjust the head height or i must report to an roland engineer? Ty

The BN-20 head height is fixed, it does not have changeable head heights like on other machines. The overall head carriage may be aligned to the correct height by a service engineer, if it is deemed as being out of position.
