My printer ran out of blue ink over the weekend and all my line got cross contaminated on my VJ-1204. All lines went to black. I ran solid C,M&Y through the line to get the cross contamination out. The C and M cleared fine. The yellow hasn't. I have run about 30% of a Y cartridge / a...

Thank you so much for your input!. I'll start with some fresh dampers and see if it will eliminate the issue.

My Mutoh 1204 sometime experiences cross contamination of my M ink? When the machine sits a couple days without printing or over the weekend sometime when I come in the magenta lines are cross contaminated black. I have to run the M ink solid for awhile to get the M back to printing the...

After running some vinyl with the covers off, playing with the tensions, I noticed the PF motor wasn't turning. I gave the belt some subtle manual persuasion and it got the wheels turning and they have been still spinning with a few print restarts. Now with the PF motor spinning it seems my...

I looked back and I do have the tensioner set to the same location it was set before I changed out the carriage. However there is alot of slop in the tensioner, to the point where it wobbles. I'm experimenting now with adding some tension slowly to see if anything levels out

I have a image attached of where the belt is riding on the cr motor. The belt is butted against (rest on) the lip that is on the bottom of the drive gear of the CR motor. Should there be more tension? will this belt ride higher on the cr gear if there is more tension? I also highlighted in...

Thank you so much for all your knowledgeable input. The bearings from the previous carriage were all spinning freely, non were seized. I inspected the race way, there visually isn't any wear at the points of contact of all the bearings. I did mess with the belt tension at the time I did all...

Thank you guys for all your input. I'm processing it all, thinking back this issue probably did start when I changed out the carriage assembly. I swapped out the assembly with an entirely brand new one. You asked about the "bearing raceways": Are the bearing raceways the 2 bearing that are...

If there was an issue with print head alignment wouldn't it effect all colors? Only the C and the M are doing this. I find it tough to believe a carriage bearing is at fault because I replaced the entire carriage assembly within the last 3 months. I didn't quite follow about the media...

No the carriage is pretty quiet. I replace the CR motor within the past 2 months. Also the carriage assembly was replaced as well.

Any idea why I might be getting this type output from C & M? the Y and B that print are super solid. I'm printing on a VJ 1204. The nozzle check I ran was flawless. I'm thinking possibly a heater or damper issue? Just looking for some additional input. I'll probably start by changing the...

That was it. Thank so much for the reply. You got me fixed up.

I swapped out my carriage today due to some bad bearings. Printers back together and printing well aside from where it is starting my prints on the media. I have a picture attached to better show my issue. My printer is starting the prints approx 1/4" before the medias edge. Anyone have any...

Trust me DIGIprint doesn't have them. I had an order placed with them over a month ago and they were to be coming and just the end of last week they canceled the order. I have spent thousand with digiprint. BAD SERVICE. Don't promise the customer a part that is needed make them wait a month...

You're 1000% right once the first one went they all started to go. I sincerely appreciate the feedback. I'll give them a try to get me thru.

On my Mutoh VJ printer my pressure rollers have all the sudden started to break down (almost 10 years old) and disintegrate in a sense. I ordered some and they are on the way but it looks like it takes a few weeks for them to get here. I have pulled a few out that have failed on me and...

RG I sincerely appreciate you devotion to my issue. The little charge did the trick, I cannot thank you enough. The cross contamination is gone and my test prints look PERFECT again!

It seem I was able to get the black to free up and now I can pull ink thru the installed dampers. To be sure I was making the right steps I also decided to change the blue dampers as well. When I stopped last night I was still not getting proper output from the cyan and the black. However...

You maybe correct. I have all the covers removed and there are no kinks in the line. I can clearly see the black ink line from the cartridge is empty. How exactly do you backflush the line?

What should I check if I cant pull ink through a line? I started to experience issue with printing black, I replaced the black dampers and I cannot prime the dampers? I did pull out a blue damper to see if my method was incorrect. But was able to properly syringe the blue thru. Any...
