I believe there is an unlocking screw directly behind the maintenance station/carriage that is visible when you take the right cover off. If you turn it with a torx screwdriver you can unlock the carriage. But an easier thing to do is to unplug the printer when the carriage has moved out of the way during its initial system checks.
Thanks for the reply...I actually have no problem moving the carraige away as I do the same thing, open window sensor and unplug. But there are rubber wiper blades in the station, and I thought those may rotate or move forward and back to clean wipe the heads. I was able to access 2, and there maybe more further behind.
Well, I took the problem printheads out, and bathed them in a 85% distilled water/10% IPA(not the beer, the alcohol)/5% or less ammonia for about an hour.... And it did improve the nozzle check greatly. I still have a maybe 10 or so 2mm lines missing total, out of 11 inks(hard to tell on the clearcoat). So I ran a print that has a faded looking banding as if its just an impression, not a skip or gap every 2-3 maybe 4mm.
I am guessing it is not the issue under the carriage as yours, as I dont really have and mess on the prints, but I though the printheads were getting dirty from that. I wonder how you cleaned it, did you remove the carriage?
Really frustrating. I have gone through a lot of Premium Instant dry 36" roll, a few set of printheads, and a couple inks . I know the inks should be at least half full, as Mark Lindquist has mentioned this as a possible issue when doing cleanings or such issue testing.
