Printer problems, colour dropping out
Hi folks, as stated im having printer issues. I understand most of you dont have a Mutoh but hoping this might seem like a generic problem that you may have come across before.
So printer in question is Mutoh VJ eco solvent-
So 2 incidents which i believe are related, 1, last week i was printing some red wallpaper and the colour started to change to more of a brown. i did nozzle check and everything was good, kept printing but it continued then i get flashing lights and sirens telling me the Magenta sub-tank is empty. I check the Magenta ink levels and it has 10% but the cartridge seemed empty (i later cut it open and it was empty) so i changed it for a new one and did “little charge, sub tank refill” and we were back up and running. Since then ive only prined few metres.
2, today im printing large orange and grey stickers, i get 5 metres into the job, start printing same lot again and straight away the orange looks like shit. i try again and again but it keeps getting worse, 2 nozzle checks are fine then the 3rd shows magenta missing half its nozzles. Now i know i have nearly full magenta cartridge, i do little charge and sub tank refill again and off we go we are back to the races. Im now printing 4 metres in but expect it to soon do the same again.
Seems to me Magenta related
So, any ideas what this could be?
Update, printed that run fine, then resent the job and no magenta again
