- The ink line clip fittings come off beautifully with little force. - It's the electrical multi-color ribbon cable for the printhead that is passing left over the top of subtank-1 that I am struggling to disconnect. It's about 2" wide with double row of wires bundled and wrapped in foam, and...

For the Black: - Able to disconnect at solenoid and confirm valve drips steady when pressed - Stuck at subtank side unable to get ribbon cable out of way to access For the White #7 - Able to disconnect I-7 at the solenoid - Solenoid does NOT drip when pressed ( can valve be cleaned?) - Able to...

I cannot remove the wide ribbon cable plug that is blocking my access to the blank ink line at the top of subtank#1 - I was able to squeeze to unblock the side tabs, but it won't budge, and I am not sure how much force is should use to lift it, and if I can rock it back and forth to try to work...

You are spot-on about the black and white being the worst. I was unable to complete the cleaning cycle and tripped "ERROR 61b" Ink supply. It notes ---4--78 .I think that points to the subtanks not showing the right ink levels for the black and 2 white channels. - # TEST / sensors, shows...

I will try your suggestion for cleaning cycles. Does the machine do any cleaning on normal boot up or power off? I am open to recommendations on what is best as far as using old inks vs new. The inks that came with the machine have expiration dates from late 2022 to mid 2023. The machine was...

Im so sorry to be asking stupid questions, but I am not really clear on how exactly a line flush is done. I purchased two 1-liter bottle of Maintenance Liquid 07. Hate to take up so much of your time, but is there any pdf or video of step by step process to go thru and flush the important areas...

My machine does use LC/LM / W /W on the right head. - Are you saying it's safe to use rubbing alcohol to actually put into the lines and subtasks? - Do I actually flush out all the old ink somehow first? - I have not run any cleaning cycles or print tests yet. Was wondering if there is a way...

I am grateful that the machine is powering up consistently and I am trying to shift most of my focus now to a through cleanup and efforts to save the heads from any damage due to dried up ink in the system due to printer sitting unused for months. My flushing solution 07, and the small bottle...

Thank you for clarifying. I completely missed that I was in all along and was expecting a different main page. Silly mistake. Thank you

I tried Func1 & 3 without success. Tried to do about 15 attempts including letting go at the beep, letting go after, holding power as well (but then no beep occurred) ... Each time it powers up into the main Home Screen with the ink levels at the bottom - Is there a particular timing that I...

I'll wait some days before trying to do firmware updates just to make sure the machine is operating in a stable manner and not going to hang in the middle of an update. Any suggestions on the process to get into the service mode on the 2.2 version and reset the clock Thank you

I was able to make further progress today. There was another forum here that stated the "F/W updating..." error has to do with the keyboard enter key stuck. That pointed me in the right direction, although none of my keys were stuck, but turns out the pcb is very sensitive to contaminants on the...

I have some good news. I tried to add a few more connectors and boot again and it repeated the earlier test with lights on the new station iv PCB followed by shutdown about out 15 seconds. I decided to go ahead and connect the CT board, and remaining connectors and try again and, thank God, the...

I have not been able to find another switch on the front. That said, on the keypad, there is a "Enter" button that lights up in blue when the machine is turned on. That continued to be blue after the power seemed to shut down and screen turned off. (And I think it is Pchannel based on part...

My flushing fluid and some parts finally arrived today. Do you have any suggestions how I should use the flushing fluid to clean out the machine and hopefully try to preserve the heads. We are assuming the machine has not been run in 14-18 months and potentially sat without power for months...

Some updates: I did a number of tests using this technique and seemed like continuity is there back to the main PCB. Checking voltages made me suspect the the MOSFET on the back of the station 4 board may be the issue because it has 36V at the source before powering up, but then 36V at the Gate...

Ok, I will go ahead and measure the FCC and reply back. Is there a way to know which pins on the FCC should have voltages, or should I just check each one? - I did try calling some mamiki sellers including my local supplier and am surprised how so many part numbers are not stocked and have long...

The picture I posted was referring to the note posted with it about rotating the pumps, etc. safely. Did the text not show with the image? Thank you for the latch info. I was able to locate that and have been able to slide the head over successfully.

As I go thru the machine physical cleanup, is it safe to manually turn items like pumps, motors, etc. For example there is what looks like a shaft protruding to fit some tool on this pump. I want to check for anything that may be seized with cured ink, or possible points of leaks, etc. - Can...
