, , , ,

In the world of large-scale printing, printhead problems can significantly impact productivity and output quality. However, while a permanent fix is underway, there are innovative temporary solutions to keep your operations running smoothly. In this article, we explore these creative workarounds, including the ingenious use of fake black simulation through Cyan, Magenta, and Yellow channels, and the strategic doubling of colour channels. These practical techniques serve as a lifeline, ensuring your printer continues to perform, even when faced with the most frustrating printhead issues. Let’s dive into these fascinating temporary solutions that provide real-time results.

Each Printhead has many chambers, and sometimes due to damage, one or more chambers blocked or damaged. You can choose to use the printhead to print white but not all clients have the need to print white or the printer does not support printing white. So, we can also choose to manipulate the color in original settings and still get a good result print. This is a temporary fix and we recommend to change out the damaged printhead for a new one.
