Email this guy about unlocking the printer. geshkin@ukr.net He's in Ukraine. Apparently, he has helped a number of people on here unlock their Mutohs. I don't know what he charges, but it's probably worth it, between ink loss from bad cards and the sheer frustration...

I'm assuming you are talking about the random dark horizontal lines. If not, you need to be clearer about the problem, preferably by marking up the pic. And lighten it up a bit please, it's dark and hard to see. This is likely because of the weight of the roll of banner. The SP-540 can...

And make sure the brackets these rollers fit in are screwed tight on the bottom of the printer. If one of them is loose, the supply rollers will not be parallel to the printer and cause skewing as well...

Make sure the pinch rollers are clean. The easiest way to clean them is to use alcohol and a foam swab. Run the feed aging in service mode and hold the swab against the pinch roller, being careful not to let it get caught between the pinch roller and grit roller. You can also clean the grit...

You need to see what they are going for by doing an online search and on Ebay. Factor against that how much heads, etc. will cost to get it operational, plus your time. You didn't say how it was printing before you decided to replace the manifold. Based on all that and the PITA factor, if you...

Have you checked to see if the BN-20 is showing up in the service application?

Agreed! I do have a lead on an original XJ board, so I'm going to pursue that route. Definitely don't want to kill a good existing XC mainboard!

To the tech gurus! I know the mainboard from the XJ series is compatible with XC series, but can the mainboard from the XC be changed to work in the XJ series? The mainboard compatibility chart states once a board has the firmware for a model loaded, it cannot have firmware from a different...

Also, be sure your VersaWorks is a 5.xx version, as the SP300 will not run on VW6.

Mixing brands of ink is something of a crap shoot. Even though ink manufacturers claim their ink is compatible with OEM ink, there can sometimes be minor issues that only show up in certain circumstances. Or they can be extreme. Years ago, I was working for MegaInk and we learned that, even...

Look to see how much free hard drive space you have. A lack of free space can really slow everything down. Also look at your print queues and consider either deleting files or moving them to a backup folder if you need to keep them.

Rather than bypass the choke valve, which is incredibly useful, replace the flexible tube that is pinched closed during the choke valve operation. Roland does not carry it anymore, but this should be a perfectly good replacement. It's the correct size, flexible and is solvent resistant...

Good to know your level of expertise, makes it easier to help. I can see this is a strange problem that requires out of the box thinking. You said you have dealt with choke valve issues in the past, have you verified that it's working correctly? It seems to be the only common point for all the...

You absolutely must remove the printhead from the brown head adapter plate. It is physically impossible to remove the manifold screws without doing so. You might need to remove the nut with the white RTV from the old manifold if the replacement manifold doesn't have any. The best way to remove...

Correct me if I'm wrong, but it sounds like your problems gradually started with a captop replacement about a month ago and now won't go away with a new captop. I've attached a pic with 2 things to check - that the spring on the front of the captop (critical for head to captop alignment) is...
