printhead

Hello, I'm fairly new to wide format printing. I purchased a Mimaki CJV150-75 in '22 to be able to print marketing materials in-house (stickers, banners, posters, etc). I don't print every day, but I do at a minimum run test prints everyday to make sure everything is in working order. About...

I've been trying for a while to get an older UCJV300-160 up and running again. My current problem is ink pooling on the underside of the left printhead ( stage right ). I'll call it HEAD 1. So far, I've replaced the following: 1. All the ink lines / tubes ( MP-M018909 ) 2. Cap bases (...

Hi everyone, I’m encountering an issue with a DX5 printhead, and I hope someone here can help. I’m a service technician and have personally replaced over 100 printheads, so I’m familiar with the process. In this case, I’ve ensured that the new head ID was properly entered each time. I...

I have a Mutoh VJ 426UF. After installing a new head, I did a nozzle check and noticed only one color wasn't printing. I figured something must be wrong with the damper and tried to change it. I accidentally disconnected one of the cables while the printer was in standby. The machine made some...

Hello everyone! I have a Roland LG 300 UV printer and have been using it for a while. Lately, I've noticed an issue when printing black and white designs: some spots appear faded compared to others. This doesn't happen with color prints; they come out perfectly fine. If it were a printhead clog...

I have a Roland sp300i and I’ve always printed on vinyl and banner and have never changed the height of the printhead. I am not even sure if I can on my printer. I just replaced the printhead and have to print on double sided 13 oz banner which I have done before but now I wonder if I need to...

Printer is about almost 2 years old. Last year printer was ghosting and printhead 1 was having problems with black that cleaning would not help. It is unknown if these problems are related. A tech came out and replaced the mainboard (fixed the ghosting) and printhead. This fixed the problem...

Hey y'all Was hoping someone could help me with an issue that was just brought to my attention. The other day our designer was replacing the Y/M Printhead on our HP Latex 365 and decided to show me the old one. It's pretty torn up, which, of course, is why he was replacing it. He then...

I'm wondering if there is a way to print using only 1 of the 2 print heads (A & B) on our XR-640. We've got a bad head (B) and are working on budgets to get it replaced, but it would be really awesome if we could limp along on 1 head for the time being. We can do this on our Epson S80600. I've...

I had a tech come on Friday because I was getting bad banding and black heads not firing. He replaced the head a and the nozzle check looks bad and it still prints terrible.Looks like my optimizer channel is not functional too. He’s coming back on Monday but I’m afraid he may not know what he’s...

hi! I just got a problem with my Mimaki UCJV 300-160. Head 1 is missing the complete CYAN channel. 5–6-time cleaning + 2 sessions of Ink Fill-up and it is not coming back :(. Did any of you had a case like this? is there anything that can be done??

Hello, I have had some issues with my HP FB750 printer for some time. I have tried manually calibrating the printer or doing the automatic calibrations and cannot get better results. After talking with HP support, they recommend that I replace the printheads. The repair cost for the labor seems...

I was trying to print out a past job and noticed that my blues were not clost to what I had before. I figured out that it was because an entire nozzle isnt working for cyan on print head 2. Any idea how this can be fixed without replacing the nozzle. Ive done a manual cleaning and several head...

Hello, I am going to be replacing the Black / Cyan printhead on my SP 300i. I have the printhead and bought a service manual, read several times and searched videos. I think I am going to be ok, just have one question for the community. In the service manual it states after install go into...
