Fiber or hair on the head is one possibility, but not the only one. Media contamination is another viable possibility. Contamination is not necessarily visible to the naked eye, and will only manifest after ink has been applied. A third possibility is that the media is being over saturated...

Sorry, but you are asking the wrong question. You are not using different working space 'profiles'. You are using different Rendering Intents. A rendering intent defines the behavior for out-of-gamut colors, in terms of remapping into the destination gamut. Different rendering intents will...

Why not just load the machine as a roll?

Both of the Presets you show (Pre-Press US and Max Density US) use the same working space profiles; RGB=Adobe RGB1998 and CMYK=US Web Coated SWOP. They differ in the Rendering Intents that are being used. The Pre-Press US preset uses Relative Colorimetric for both raster and vector, while Max...

More than likely, when you are loading as cut-sheet media, the printer is assuming that standard sized (ANSI or ISO) sheets are being used. ANSI for example a standard ANSI C cut sheet is 22x17 inches. I would load as a Roll instead which is undefined in the length direction. You are...

Which model of Latex is this? Assuming that it is running Yellow and Black through one head, as was the case on the L2 machines, you are seeing cross-contamination on at least one of the YK heads. I would suggest that you run a nozzle test print (Ink Menu > Image Quality Maintenance > Clean...

There are two distinct considerations: 1. Is the media (posterboard) able to be moved physically through the printer's paper path without causing headstrikes or other issues with media transport? 2. In the case of eco-solvent inks, does this media contain a coating for the inks that you...

The first thing I would do is to reset CM3 to factory default settings, this can be done in the CM3 program, File Menu > Preferences > Advanced screen > Restore Factory Defaults.

Please describe your workflow (what app are you designing in, what RIP & printer, what cutting plug-in etc).

The resolution of the raster data that is sent to the printer from the RIP is what can cause this issue. The early drivers for the Latex 360 were sending 300 PPI to the printer, and that resolution can cause small text to look a bit fuzzy. This issue was resolved with newer drivers from the...

HP Latex printheads are warranted as a separate consumable from the printer's warranty. That warranty is for 1 liter of ink to pass through the printhead. You state that it is the #3 YK printhead that is consistently causing the error, so I would clean the inter-connect on the carriage for that...

In the Image Quality Maintenance Menu on the printer is a setting to enable/ disable Extra PH Cleaning. If this is enabled, the heads will be wiped on each pass, which will consume the maintenance cassette much more quickly than if it is set to disable. In most cases there is no benefit to...

I think that it is save to assume that human nature is that we all tend to like and recommend what we are used to using and will recommend it. My advice (worth what you paid for it) is for the OP (or anyone else who comes across this thread going forward with similar questions) to look at the...

If the machine was properly shut down, and ink was purged before the printer was shutdown, you should be good for an indefinite period of time. When you decide to power it up. you'll need new cleaning carts and ink carts, and following an ink fill procedure (less than 1 hour), you should be good...

Does this mean that cleaning fluid was run through the machine prior to when you powered it down, or simply that the ink cartridges are not installed? If it's the latter, you are in for a lot of work to get the machine printing again.

Turn it on and run it ASAP! Literally the worst thing you can do with any solvent printer is not print (assuming that inks are in the machine). After sitting six months in a powered off state I would expect that you will need to perform a series of cleanings and probably purges and hopefully...

There are various derivatives of the term cross-linking, in biology and polymer chemistry. In this case, it refers to synthetic polymer chemistry, and cross-linking does indeed happen upon contact between the Optimizer and colorant inks in the HP Latex 3000/ 300 series inksets.

This is wholly incorrect. Ionizing water simply changes the PH balance, making it more or less alkaline or acidic. HP's Optimizer is cationic (positive charge) while the other inks are all anionic (negatively charged). They cross-link upon contact with each other. The presence of the...

+1 to the previous comments on incomplete curing of the ink as the likely cause of this.

The primary root cause of horizontal banding (in the carriage movement direction) on inkjet printers is directly tied to printhead / nozzle performance. With the HP latex printers, banding will not become visible until a significant number of nozzles are lost, but because the thermal printheads...
