Try adjusting the media feed. Depending upon the printing pattern you are using, the Mutoh printers will give you vertical banding if the media feed is off, especially in the wave pattern.

Please post a clear closeup pic, especially if you can print some small text.

Reprint the file in Uni-Direction. If it looks better, you need to do the bidirectional adjustment. See attached. Use the detailed mode.

Is this fuse located very close to the big black heatsinks? If so, it is the fuse for the output from the mainboard and will definitely be your issue. I believe it is soldered on to the board. Do you have someone who is good at soldering small parts? If not, I offer board repair services. Call...

Sounds like the needles had some dried ink in them. Glad you are up!

Isn't that the truth!

And I thought I had all the tools I might possibly need...

This can also be an indication you have a damper starting to fail and allowing ink to accumulate on the head, as suggested above. Try printing a large solid that has black content and see if you are getting any banding from black dropout, as ink on the head will also cause missing nozzles. The...

Repairing these pumps is not the best approach. This pump style has always been considered a replacement part. Do yourself a favor and replace it also, but with a Mimaki OEM pump. In the case of this pump style, you get what you pay for, and generic pumps are known to fail prematurely.

If you are unable to pull ink to the damper with a syringe, you have a supply issue. Check the ink cartridge, making sure it has ink. PLEASE NOT TRY try to get ink to the head by pulling through the cap, as you will possibly damage the head. When you pull on the ink line, are you getting...

You need to figure out how to get the stripped screws off the new head. They should have come off easily to begin with. Be sure to use the right size Philips screwdriver. Before installing the old manifold on the new head, flush it with acetone until it shows clear, otherwise you may have dried...

There is a lot of confusion around the DX6 and DX7 heads. Long story short: Epson makes all of the heads I am about to mention. The DX5 print head was/is a very popular print head that Epson licensed out to 3rd parties to use in their printer designs. The DX6 head was next but Epson didn't...

I would suggest reseating the head cables, at the same time checking the cables for any ink or damage.

If you clean off the ink on the bottom of the head, does it still continue to drip?

First, you definitely need to replace the wiper. The issue you are having is most likely an air leak or damper failure. Have you had any head crashes, as head damage is also a possibility.

Justin, Send your email to the email in my signature line and I will get you the manual you need...

One more thing to check, one of those head slap things. Pull the ink cartridges and make sure they all have ink. The cartridges have been known to run empty and not stop the printer, causing what you see. I know, having spent an hour on the phone with a Bahamas customer, only to check the...

If you have air in the ink lines, you want to pull from the dampers absolutely, not the caps. To draw ink through the lines requires too much suction and time to pull through the heads and you will probably damage the heads in the process. Now if there is no air in the lines and you are trying...

Thanks for the correction, appreciate it. I never want to point someone in the wrong direction!
