Roland XF640 Banding Problem

Hi Guys,

I am having problems with my Roland XF-640 EcoSol.
I recently changed the "B" head to a brand new head.

Attached is a picture of the nozzle test as well as the print.
Ripping through VersaWorks with Generic Banner Profile on HighSpeed Mode - printing on PVC.

My calibration is set right; and the nozzles are firing correctly (except for one black nozzle.. busy sorting that out but i doubt it's the cause).

If anyone could give me some advise as to why this banding is happening i would greatly appreciate it!

Regards,
Keith

 

Hi Joe, thanks for the response. Do you by chance have the service manual for the XF or know of anywhere where I could instruction on how to calibrate the machine myself?

I can get into the service menu but do not complete understand what I am looking at when doing to calibration and alignment prints.

 

Hi there, no o did not; but I ended up stripping the printer and fixing it myself.

It wasn’t easy but now I have a very good understanding of the machine.

Do you need help or do you have the service manual?

If you I have it, I would still really like to get my hands on it.
