Need Help old ROLAND SP-300V problem

[guillermo]

thanks, there is black ink in the cartridge i checked that first. Also black ink line/tube and damper are looking normal. I suspected black was made out of other colors but here i tried to explicitly print black only, test rectangle made in flexi sign and by print setting "color managed by printer". Is there any direct way to print just black in Versaworks, to somehow avoid this "mixed" black? also makes me think if the software was cheating and made black in that way for a longer time then black nozzles were not working much and that would explain too why my black cartridge lasted so long..so basicaly software and settings issue - maybe that is how i made my black nozzles stuck -they simply were not working much except by cleaning cycles? Any other idea maybe?

that is not the case... as you do not have any black on a test print.

TRY THIS AT YOUR OWN RISK
(it often works)

consider using a cleaning cartridge with about 5% acetone in the cartridge
pull enough through the tube to get the acetone reaching the printhead

let that soak for a couple hours. do several cleanings

now print a large rectangle to get the acetone out of your head, lines and pump

it is often possible to salvage the printhead this way. (it is an adventure the first time, though)
