HP Latex 310 Printer

#1 rar 3 years ago

Hello

I have problem with my HP Latex 310

When i start printing black CMYK 100C100M100Y100K everything is OK

But after printing a 20 cm color fades as if out of all color ink /look on images/

services support on my country send me answer that is faulty ink management.When printing in color does not make me this.

Thank you for your response.

Why would ever want to print black using CMYK 100C100M100Y100K. Haven't you noticed that the best black with latex ink is 100K. In fact most RIPs have a setting to print pure primaries or black as inkjet black which turns color management off if you want to print the pure 100% colors of the printer, like your linearization targets.

It sounds like your getting ink starvation. Slow your printer down by increasing the passes or adding inter-pass delay if you want to print like that.

Before, I still print like this and did not make printer this problem.

Could this problem cause dirty contacts on the optimiser head ?

Hi rar,

For your description, your issue may be caused by one of this two things:

1- Your Optimizer printhead has some issue. The the color shift may be visible in all colors. I'll recommend you to change the printhead.

2- The issue is caused by the media. I'll recommend you to use another media and please let me know which media were you using.

Hope this helps.

#5 Check ALL Printheads health with diagnostic image. Replace any Printheads not providing suitable quality. Do some test swatches to get correct colour.

Avoid printing 100% of all CMYK values. You will be using too much ink to get a suitable coverage and it would be unnecessary. You can use less ink and get better results.
