Printer Epson C91 leaves white streaks when printing on the entire sheet, why?
Printer Epson C91 installed CISS with dye sublimation ink. Until recently there were no problems. Since the beginning of the burst tubing black ink, replaced. Not always to print out a fully completed worksheet. Now a white horizontal strip across the image, especially in dark places. What to do?

Clean nozzle or replace the cartridge.

Nozzle cleaned, and nozzles cleaned - different States of purity. If you are unable to clean yourself, take it to STS. But in 80% of the head of the skiff.

The problem is not in the head and nozzles. The problem is in the ink. They thicken over time, changing the viscosity. And when you print dense filling of the ink just do not have time to flow to the nozzles in the desired quantity. As an option - pozabite mesh at the entrance to the head (under the plastic needle). Had the same issue with pigment ink. Translated into dropsy - which is all good. Dropsy is thinner than just.
