LEF300. nozzles are constantly clogged

Post by WillForce » Tue Oct 22, 2019 9:12 am

Good afternoon! I own LEF300 for one year. I have a problem, nozzles are constantly clogged. We do manual cleaning 3 times a week, automatic cleaning is always on.
I enclose a photo of the nozzle test.
3 months ago they changed the head of Magent / Cyan.
Regularly change CAPTOP and dampers.

I also have LEF200, I have owned it for 2 years, there are no problems with it!

Can someone tell me what the problem is?

Have you replaced the mist filters in this time? What are you printing and are you using a jig?

we replaced everything that is possible. We mainly print on pens, flash drives, black and transparent acrylic.

I was told that due to the fact that on the LEF300 there are only 2 pumps for 4 heads, this is because of this problem. Since 2 pumps cannot pump ink correctly, 4 pumps are needed. This is a defect of Roland!

Look at having the LEF2 upgrade with the head refresher, this will reduce the ink build up on the heads causing the nozzles to be blocked. It doesn't look pump related, as its only on a couple of nozzles.

Then explain to me why I have no problems with LEF200?

Is there anything different in the methods you are using or the items you are printing, also how often do you perform maintenance?

It is strange that it's only happening on the 300, have you updated to the latest version of firmware which optimises the cleaning routines?

as I wrote above, we follow the machines very carefully. We perform manual cleaning 3 times a week. We print the same products on lef300 and lef200. We also have roland support installed, which notifies you of updates, and we immediately update the software. At the moment, software 2.40 is installed on lef300. I also remind you that Lef300 has been with us for 1 year, and Lef200 has already been 2 years old.
