Problem:
About a year ago there all my jobs started having a tint of green. I noticed that if I add magenta in Photoshop, I could compensate (somewhat). I have already berated myself for not doing my daily test draws. I finally ran a test draw (first in a year) and saw my Left Side of the Magenta completely missing (Right side Magenta and all CYK were 100%)
Procedure:
I have performed numerous head cleanings in the hopes that it's a seriously clogged head. I have done a nozzle wash (soaked 24 hours at a time) each day for the past 4 days.
In an attempt to help the procedure along, I took a manual engraver and placed it against to metal near the head (a couple of times for a minute or so each time) in hopes that the vibrations would translate and help the procedure along.
Per my Mimaki tech's suggestion, I filled the cap with acetone and soaked the head for 20 minutes.
While the other nozzles are spotless, the left magenta test draw remains completely blank.
All dampers are full. Hoses full. Pump is fine. I've been printing regularly unknowingly on the rest of the head for over a year. Ink has never been expired and I always had the second ink (CCMMYYKK) full. SS21 Inks from Mimaki always. Printer is 3 years old.
Note: Since I had the Pre-fill solution in the head cleaning slot, it never told me I was out. I have been running this way for I can't say how long. (I was told that it's the same solution, only that the pre-fill won't let you know to change it. Wish I knew that before.)
Questions:
1. My tech says he has never ever had a clogged head that wasn't recoverable. Any truth to that?
2. Is this common after a long time or is it possible it's the damper or slider board?
3. Should I continue my overnight nozzle washes to endeavor to unclog it?
I would greatly appreciate any assistance. I will be happy to post any and all tests and results until I resolve this.
