the worst vertical banding ever

[midnightmadman]

Can someone look at this and tell me what it is?
I've seen it happen before but never this bad!
I'm using a new roll of avery mpi 1005
Mutoh 1204. I ripped all different ways with flexi 8 and also photoprint10
And it come out the same

Cut a section to the same width as the roll and feed that section into the printer after rotating it 90 degrees. Does the banding still follow the feed direction? If so, it's definitely the printer, otherwise, wow is that a borked roll of media.

Trying it now, but I'm thinking its the printer

 

[midnightmadman]

Same either way

encoder

clean the encoder

HOLY cow. It got worse. I cleaned the encoder strip greased the rails and did a new rip.. I am going to go nuts!

I would suspect the media. Try another roll of something else.

 

[midnightmadman]

Nozzle check is PERFECT too

I flipped 90 degrees and got the same result

Check your media feed rate... We had a similar problem and Mutoh provided this as a solution. (VJ1614)

Thank you. That helped 'vertical' bands going from top to bottom?

 

[x2chris7x]

Yep... Didn't think it would but it did, we had Mutoh tech in here for 2 wks trying to fix a similar issue, but our vertical banding was present in Magneta only... weird. The feed rate didnt fix the problem completely though, the tech had to set up some new profiles... but this was after new head, dampers, and maintenance station... Checking your feed rate is at least worth a try, just to see if its off or what it should be

Strange because the bands are in the exact same spot each time I try it with different setting etc

I am willing to bet your encoder strip looks "cloudy' and not clear. I've seen it a million times and a new encoder strip always fixes the issue.

It looks like a 10-15% window tint but still looks clear.. is it supposed to be clear as in no tint clear?

Avery has been having that issue for a month or two with that media, try a different media and the issue should go away if the printer is dialed in correctly. I had the same issue on 2 separate 64s, different media and the issue was gone. Avery is aware of this, we sent them samples...

Like i said.

 

[midnightmadman]

Just tried some mactac with a lower heat setting and same exact result. Is it some sort of ink starvation maybe?
