Hello guys,

I'm french and I need some help about banding. I don't know if it's the correct word

I have banding on a VP 540i.

This kind of banding looks like a lighter band and this phenomenous is completely hazardous. sometimes that's happening just after several inch (about 10). see the attached scheme

This what I have checked:
- feed motor calibration (service menu)
- pinchroll pressure
- take up motor tension.
- encoder strip and calibration (service menu)
- capping and pump. I swapped the 2 pumps
- swap head cables
- swap printheads and print 100% of each colors
- create a new profile ICC

I will check dampers also but their don't look like damage.

do you have an idea? do you know this problem?

thanks in advance!

Romain

Bonjour!

we have this issue sometimes on our machine, is the printer is a controlled environment (humidity, temperature)?

if you are in a bind and need to get a job out the door, I have run in uni-directional high quality before and it goes away, but it's painfully slow!
