Thanks for the feedback. I also posted in the Digital Printing forum and had 3 solid recommendations for Clean Cut blades. I have ordered some blades from Clean Cut for evaluation. https://www.cleancutblade.com/ Regards, Jim Hancock

If it is doing the "exact" same thing on both the old and new printheads, then you most likely have a bad ribbon cable. Power down, unplug, then remove the ribbon cables and examine the traces for any damage.They are not very expensive, so I would suggest you replace both of them. Regards, Jim...

Thanks for the recommendations. I have ordered some and will have my customers try them! Regards, Jim Hancock

Looking for suggestions (from actual experience) from users as to which specific contour cut blades seem to have the longest life for general printed laminated vinyl. A part number would be great! I am a tech in South Florida and get frequent requests for such a recommendation from my customers...

Power down and unplug your printer. Then check all the ribbon cables going to the heads to make sure they are seated all the way into the connectors on the print heads and are sitting square, not at an angle. Especially the light magenta. I suspect the ribbon cables for the light magenta are not...

Glad to be of assistance! On your heavy black, some questions. What ink brand are you using? Have you tried other profile settings? Does it do it on all your materials? Regards, Jim

Glad to be of help! Regards, Jim Hancock

Started a conversation with you. Regards, Jim Hancock

Yes, as has been suggested, replace the magenta damper. Also clean around the post on the print head where the damper goes with a swab damp with cleaning fluid to remove any dried ink buildup. In addition, replace the O-ring on the ink line going into the damper. Examine the tubing where the...

It appears in the process of changing the dampers, you may have knocked the ribbon to the magenta/yellow head out of kilter. What you are seeing I typically see when a ribbon cable isn't properly seated and the print head goes into a free fire mode. I suggest you immediately power down and...

Before you replace any parts, you should do a complete head alignment in service mode. Your print heads are seriuosly out of alignment. This will include bias - which insures the heads are straight and parallel to each other, then the vertical - which lines all the heads up with each other...

I agree with rjssigns on the parts replacements and to assess printhead condition. Service menu is Down Right Left Up Right Down Left. Then hold Left Down Right while clicking Power button. Keep in mind this. The nozzle test is like starting your car and it idles fine. Printing is like running...

I would agree with GAC05 on this. It appears to be to be ripples or tunneling of the media. In bi-directional printing, the alignment is dependent on the head to media distance remaining consistent. This head to media distance changes in the area of the tunneling. When this occurs, the...

I have been doing tech work on Rolands since 2004 and am not surprised by what I see here. The older Roland printers using DX4 heads have a tendency for the black head/channel to go before the other colors. What is shown here is typical. The black ink uses carbon black as a pigment, which is...

It sounds like a rapidly repeating sound, leading me to suspect some buildup in the drive gears on the scan motor system. Check both gears at the scan motor. An old toothbrush is good for cleaning the gears. Also put a drop or 2 of light weight machine oil, like 3in1, in the bearing for the...

I agree with Solventinkjet's observation. Your tech definitely needs some more experience - "tech said time ago there's a huge risk of permanently damaging the printhead when dampers are changed", as this is absolutely untrue, unless the tech is clumsy and breaks the nipple on the head...

Please do not use 70% alcohol, as it has too much water content. The encoder is made of graphics film, which is processed in water based chemistry. The amount of water in 70% alcohol is enough to soften the emulsion on the encoder and can result in damage to it. I had a customer repeatedly clean...

What did you clean the encoder with? If you used anything less than 93% alcohol, the encoder strip is probably damaged. The encoder strip is made of graphics film, processed in water based chemistry. Lower grades of alcohol contain more water than higher grades and will soften the emulsion of...

You might consider replacing the damper for the black. Over time, the solvent ink can impact the O ring that seals the damper to the print head manifold and you lose the sealed integrity of the ink line system. This can cause slow leakage from the print head causing random ink drops, mostly...
