In this first installment, we're going to tackle the issue head-on by removing and reinserting the printhead, hoping for a simple fix like a loose connection. But here's where it gets interesting—someone has clearly tinkered with this printer before, even though the owner claims otherwise. Two springs that secure the printhead have mysteriously vanished, leaving behind loose screws and a perplexing puzzle. As we dig deeper, we uncover more clues—a severely clogged printhead, peculiar red smudges on the cables, and a suspicion that someone has indeed meddled with this machine. Fear not, for we have solutions at hand! We'll protect the printhead with a specialized film, dive into the electronic board with precision tools, and explore the inner workings of this enigmatic printer.
