AlsEU is right, one (or more) of the printheads providing wrong temperature values. But the temperature value shown in the GUI is just an visualization of the average of all temperature sensors together. This value is not used to activate or deactivate the heater system. The heating system is...

For better understanding, the color calibration (linearization) is based on the very first color reference done on the initial color calibration. This should be created with best performance of printheads and substrate advance. Sometimes this database gets corrupted resulting in color shift...

Left- and rightmost edge of the image is correctly aligned? Does it happen with all colors? The picture provided shows a solid containing cyan and magenta, and you can clearly see that all printheads stopping firing at exactly at same time. Maybe some linear encoder pulses are missed or there is...

On zund it’s spring loaded. Try with the through cut the flatnes of your table. Put a substrate onto table and set cutting deep to 0.1 mm so that it just scratches the surface. Move the knife over the whole table and check if it is everywhere similar. If not your table is misaligned

L08 if I’m not wrong is the heater, fuse or its triac.

Switch off the printer and crisscross the flat cables to the printheads and do a testprint to know if printhead or electronic is defective.

Your welcome. In addition, even if you have done a perfect alignment the cmyk droplets are different then w, because white pigments are titanoxyd. This makes the ink heavier and the droplets splatter more.

In spot color tool just reduce white one pixel

Little bit of voodoo in this chat. The only way to get a clue on the reason for your issue is to create the logs and post it.

Well explained, but in your explanation I miss the tracks to be added in between table and beam, to prevent from being wound. And the removal of air-letout of turbines, to give more space to the uneven floor. Also I would remove cleaning web to protect web wipe station in case. Securing the...

Could be also motor or electronic in the UM

Does it start to rotate during init? Prevent direct sunlight onto sensor. There is no specific position belt/sensor

Because in fact the ink is higher pigmented then in Gen3 you will need less ink to reach the same saturation. This will lead to less temperature to cure ink when running same productivity. With the 800w I can print on very heat-sensitive media, which was not possible before. White is really...

Between Z and Latex is a big difference, since the Z detects a broken bag inside the cartridge itself and latex only at the pip

What kind of ink u are using?

It’s an older Roland The cap tops are looking very used. The filter inside looks partially very swollen. I would suggest to replace them.

The part you’ve found is for sure not part of the printer. Regarding the issue, it could be dirty line sensor, encoder strip or a defective DD. Clean line sensor and encoder strip and do DD calibration.

Wipe particular with IPA and print onto. You will see immediately if plasticizers are the reason.

Offgassingtime unrolled. Regarding gamut I would not say so. But, halftone printers have bigger range to control colors. Contone printers like HP doesn‘t offer this functionality, but it’s easier to control colors in future. For halftone printers you need extra equipment and knowledge on color...

Purge is not not possible if supply is somewhere between 60-80%, no clue why. Use a new cartridge if you still want to purge tubes. And install old cartridge after purge is done.
