Cyan and magenta overlapping printing

[Mike77]

Hi, hope someone can urgently assist me. On my roland sp540v the cyan and magenta overlaps on printing when doing a fill test pattern print and in a normal print it creates a cyan/magenta shadow. I’ve done head adjustments over and over again. Cleaned the encoder sensor and and and. Don’t know what else can be done. See attached pic of tests done after all the configuration etc. trying to sort out this problem. Thank you in advance. Michael

Your vertical alignment is way off. You need to do all of the alignments in order. Bias, vertical, horizontal, bi-directional default and then the user bi-directional. Just looking at the bias print you provided I can tell the vertical adjustment is off in a major way.

Thank you for your quick reply. See attached is this the vertical adjustment you referring to. This was my last test print when doing the adjustmenst.

As per the manual and vertica test print it looks fine the magenta and black line are matching up unless I’m missing something. Tx

It looks like you are missing a nozzle on the very bottom of the head which makes the alignment seem right but it isn't. You did it right but without that last nozzle, it's hard to tell where to line it up. You need to make it so the top of the magenta is aligned with the top of the black. That should do the trick although that missing nozzle might show streaking in the prints.

Just did a vertical test print see results. Lines are in line. Any suggestions?

Tx a mil seems like it’s sorted. The vertical line have to match from the bottom up not the top to bottom. There’s still like a nozzle

Just update the problem is sorted about 99% stil a slight variation but I can’t set it anymore. Appreciate the help.
