Roland VersaExpress RF-640 ink flow problem

Post by Maximus » Mon Aug 12, 2019 10:21 am

Hello,
I have VersaExpress RF-640. It used to work properly, but after we relocated to new office, the ink flow has stopped. Only Magenta is printing. During cleanings, no ink is dropping into drainage bottle. There are also bubbles within ink tubes, and they do not move during test prints or cleaning.

Thanks in advance.

The choke cleaning is likely needed, what method was used to move the machine, did you empty all the ink?

No, the ink wasn't emptied. The relocation was not properly organized.
How to perform the choke cleaning?

I have tried to perform Light Choke Clean several times, but drainage bottle is still empty.

Try performing a limit initialise, maybe the head isn't capping correctly.

Thank you.
I also have Roland TUC-3 reel. It was working properly for a while. But for the last month it doesn't take up media automatically, only manual function is working.
