Thanks for the direction! I manually took out the Optimizer printhead and cleaned it with distilled water and its printing great again :-) I think it needed more thorough cleaning than what you get with the "Clean Printheads" operation.

Optimizer printhead usage is at 1569 ml.

Thanks for the quick reply. So I tried changing the media and it was the same problem. As for the heat you can see the quality problem as it is printing (before it gets to the heater)...

In the middle of a print job my quality has started degrading substantially... Can anyone give recommendations based on the attached photos what the issue can be? The printer is an HP Latex 315 (Out of Service Contract)

Started getting error 25.4:10 "Cyan slot ink-level sensor not working properly". I tried replacing with a new Cyan cartridge and error remained (and now I am sure I tagged the new cartridge with the error). After some research I am guessing it is the PIP sensor... my question is where do I buy...

It is a white opaque vinyl.

Yep that is one of them. The other test plot that looks good is the one that is printed and scanned when I run a 'Color Calibration' routine. You would think both of those are using the selected profiles ICC that you are running the tests from right?

When you either create or edit an output profile there is a button that says 'Test Print'. It will then create a test pattern/plot. It is on the same screen in the output profile where you set other options like saturation, heat, vacuum, etc.

When you create a new profile it has you select a similar existing profile. It then creates an .ICC file. What confuses me is when I select to print a test from that profile it looks good, but when I use the profile in the RIP it looks bad. Wouldn't it be using the same ICC file in both scenarios?

No, their is an output profile wizard on the machine.

I have an HP Latex 315 with Flexi 19 RIP. Problem is Black looks brown. I am running my test prints at 14-Pass, 130 saturation on 4-mil laminate vinyl. Here is what I have done. Any help figuring this out would be appreciated as I have wasted lots of time on the issue: 1. Black looks great on...

Thanks. I will look into all that. Nobody has ever mentioned any of that when talking to the city permitting people; maybe because it is a temporary event? portable sign? DC powered? etc. regardless I will ask about it, don't want to break any laws

Okay thanks for the feedback. As for the license I didn't know you needed a license to make backlit signs! regardless it is an outdoor road sign for a Christmas light drive thru event and powered with DC LED lights.

Finished size is about 48" x 48". I am building the cabinet. My main concern is the materials and whether it would be better to go clear or translucent for the vinyl and if I should be using acrylic or polycarb.

Have HP Latex printer and am making an outdoor backlit sign for the first time. I am using a translucent 4mil UV vinyl printed and applied to .177 white polycarbonate but am getting some bubbling. Are these the correct materials? I am worried about using Acrylic for outdoor application (and I...

I am making a backlit outdoor sign for a Christmas event with printed vinyl adhered to it. Here are my questions: 1. What plastic do you guys recommend? I know acrylic works better with vinyl but it is outdoors so I was leaning polycarbonate... thoughts? 2. To avoid seeing the LED "hot spots"...

I do have it hooked up with the thick black shielded Ethernet Cable. I did your recommendation and we will see if it works. Since the problem is sporadic it may take a while to see if worked. Thanks for the suggestion. Matt

When it is doing the initial loading and reading the marks the last thing it does is go up and down on the thick black bar, is that when it is looking for bowing? So what do you think would explain why in the middle of a cut it just randomly starts doing the maximum compensation for bowing (if...

Guys, I am still having this problem and HP support has been unable to figure it out. I pay them a lot of money each year for the Support Contract and they are SLOOW to respond, sometimes taking a week to reply to emails even though I told them this is effecting business continuity for us...

Commando that is an interesting theory. I have not laminated the vinyl. I am using is either 4-mil or 5-mil adhesive backed vinyl straight off the roll (usually GANS ARGVP). Any recommendation on how to remedy the issue if it is weight? would slowing down the cut help in that case? or doing...
