Random Nozzles Missing on Magenta
Hey guys
Noticed today that I am getting a few missing nozzles on my magenta, they’re random. When I do one test print I have 8 missing nozzles scattered about then I do a manual or medium clean and I get 4 missing in different areas still in magenta and so on, done this 5 time and just can’t get rid of them.
Tried manual cleans, medium clean, normal clean, replaced felt wiper and rubber wiper and no improvement.
Could this be the cap top? strange that it’s only magenta

This has happened to me once or twice. After being pee’d off and not getting anyone on the phone to help, it went back to normal after a few hours. I just left the machine doing nothing. Both times it happened after a manual clean. I put it down to getting a small amount of clean fluid in the capping station. Since then I’ve been more careful with the cleaning swab and it’s never happen [emoji848]

Hi Chris
Thanks. Left it until this morning and it’s now ok.
When you say you’re more careful with the swab, can you go into a bit more detail so it doesn’t happen again for me.
I currently do a manual clean every Monday morning, clean the head, capping station and wiper with a swab. When I clean the head I do go all over it but then I was told this wouldn’t do any harm.
I did have a power outage the other day for 24 hours over the weekend when I wasn’t in, I wonder if that started the issue.

"going over the head" is not advisable according to the guy who sold us our printer. Any dirt could be pushed into the nozzles. The wiper is designed to do the cleaning of the printhead face. We have to make sure the wiper is clean and clean around the printhead
http://www.largeformatsupport.co.uk/Mut … 0Guide.pdfI have the same problem from time to time when bubbles form in the pipes to the print head.
Where the bubbles are coming from I don’t know?
Leaving the printer for a while also solves it for me but is frustrating sometimes when you are in a rush. -

Yea as Philip says don’t touch the head. My bets would of been a tiny bubble of a solution on the head then. Clean round the edges only, the wipers and round the edges of the capping station, not the grate in the capping station. I do a manual clean everyday.
Annoying when these little things happen.. currently in a 45 min battle with crop marks.. [emoji35][emoji35] -

Ever notice the crop marks never work when your under pressure

Thanks guys
I’m currently profiling my printer. I’ve been getting ok results but I had a couple of days with no work on so took the opportunity to start doiing them.
Not as easy when you read different ways of doing it. Just finished so about to test my first print against another using the standard profile.
Wish me luck
-
only profile your machine to your media / ink set when your printer is working perfectly.
Profiling on a dodgy head won’t benefit you as the density will be wrong once the head is fully functional again.Profiling is probably the easiest thing to do as long as it’s done the correct way I suppose.

Thank Jamie.
All is working perfectly now, perfect nozzles, feed etc etc.
Got any tips for profiling, not sure I am doing it 100%. If you have a guide you could send me that would be great and not the Roland PDF or the video with the doctor lol as that misses parts out.

What is your rip? is it Versaworks? Onyx or what.
What Spectrophotometer are you using? and also what software are you using for profiling? or is this the inbuilt stuff within the rip? -
Hi Jamie
Using Versaworks Dual as my rip with the vs-640i.
My spectrophotometer is an i1Pro2 with i1Profiler, also have a trial version of Babelcolor to measure Delta E as I don’t think i1Profiler does that.
