Client has 3 print drums. 2 of them work fine, the 3rd, which is the red print drum, does not coat the drum evenly or does not pump enough ink. It will print fine for a bit and then parts of the center is not as dense as it should be. I have seen samples, but have not experienced the problem myself. The last
tech increased the the ink flow, but that has not corrected the issue. The customer has a small location to work in, so I would prefer taking this print drum apart once or at least know what to look for, before I do.
Thanks for any help.
