Sounds like you cracked the spigot the damper seats onto. Once it's cracked air leaks in. Or you blew a fuse, but that would kill the magenta and yellow.

Get out a magnifier and look at the yellow damper around the spigot to see if there is any ink drops that would indicate it is cracked.

Yea it broke... i found a print head manifold on amazon, has anyone replaced one before or had any luck in just replacing the plastic part instead of the entire printhead?

Installed new manifold on print head and noticed the wiper scraper was trashed so I replaced it, but the new scraper was black and not clear like the old one. Tried it anyways, but the wipers can't move past the scraper. Is this the wrong scraper or has anyone else had this same issue?

If you had a clear one before, it wasn't OEM. Roland wiper scrapers are black. It's likely that it's not installed correctly. When you install it, you should be able to push the bottom towards the back without any resistance and then it should be rigid when pushing the bottom towards the front. Post a picture if you can't figure it out.

Good Luck

No it’s installed correctly, it swings allowing the wipers to go in, but it binds up trying to come back out...

Well something's wrong.

If you are using aftermarket wipers, this is likely your problem with the wipers not coming out. Most aftermarket wipers are stiffer than Roland OEM wipers and the wiper motor isn't strong enough to overcome this stiffness on the outward movement. Either use OEM or Solventinkjet sells an aftermarket wiper that works well. You must tell them you want the soft wiper for the Roland. I have had good luck with these wipers on my service calls.

Ok finally back up and printing but I’m still having the same issue with the magenta dropping out at the left side of the print? Replaced dampers, wipers, scraper and no luck? Anyone know what I should try next?
