Q: After replacing the printhead and updating parts on my DTF Dark Horse L1800 printer, it stopped printing ink despite appearing operational. What steps should I take to troubleshoot and resolve this issue?

A: When facing a situation where your DTF Dark Horse L1800 printer stops printing ink after a printhead replacement, despite appearing to function normally, there are typically two main issues to consider. The first potential issue could be a burned fuse on the mainboard, specifically the fuse connected to the printhead. The second possibility is a problem with the driver chip, which could be malfunctioning or not sending a strong enough signal for the printer to execute printing tasks. Notably, these issues won't trigger error messages, making them a bit more challenging to diagnose.

To troubleshoot, you'll need to access the mainboard by carefully disassembling the printer's outer casing. Once you have access to the mainboard, focus on examining the F1 fuse. A malfunctioning F1 fuse often indicates that the rest of the printer's components are intact. If the F1 fuse is intact, the next step is to assess the driver chip for any issues.
