My Epson R3000’s matte black channel stopped printing. The printer had been sitting idle for a long time and when I noticed banding, I tried a couple of cleaning cycles. With each cycle less and less of the pattern was visible, until after about 3 cycles it disappeared altogether.
Because it had been idle for a couple of months, my initial guess is that the print nozzle is clogged. I found this thread on a DPReview forum that seemed to indicate so. Then again, I might be way off.
I cannot switch to photo black to test because the printer thinks that this cartridge is empty, even though I topped it up. The chip of has no manual reset. At the time I could not be bothered that much with photo black, so I left it at that. I could, obviously, insert a spanking new original Epson cartridge, but until that is absolutely necessary, I’d rather hold if off. Anyway, addressing this is for another thread.
I bought the ink and cartridges through the European distributer (Inkjetsolutions.eu). Their customer support was flaky at best (which is why I gave up on the photo black cartridge in the first place) and now they stopped selling to non-professional customers like me. Hence I’m here now
I could use some help diagnosing the problem.
