Fixing a Broken Printhead: A Step-by-Step Guide for Makers and DIY Enthusiasts

As a maker or DIY enthusiast, one of the most frustrating experiences is dealing with a malfunctioning printer. Whether it's a 3D printer or an inkjet printer, a broken printhead can be a major setback. In this article, we will walk you through the steps of troubleshooting and repairing a printer with a broken printhead.

Abby, a maker and technician, recently encountered this issue while working on a printer in the lab. She was in the middle of her cleaning procedures when she realized that the printhead was no longer working properly. She decided to switch it out with another printhead, but the printer still displayed a 0x9A error. This error can indicate a main board error or a printhead error.

After some further investigation, Abby discovered that the FFC (flexible flat cable) cables, which connect the printhead to the main board, were damaged. One of the cables had a burnt pin, likely from the frequent cleaning procedures. Abby and her colleague, Kevin, decided to change out the FFC cables in order to fix the printer.

The first step in this process is to remove the cover to the frame of the printer. Then, the three screws that hold the bottom rail down must be unscrewed in order to access the FFC bundle. Abby used a needle to carefully remove the back FFC cable, which connects the printhead frame to the main board. It's important to be careful during this step in order to avoid twisting or damaging the cable.

Once the damaged FFC cable has been removed, it can be replaced with a new one. Kevin recommends visiting bchtechnologies.com, a website designed for makers, for replacement parts. The website has a wide variety of printer parts, including FFC flex cables, that can be used to fix a broken printer.

After replacing the FFC cable, the printer can be put back together. It's important to be mindful of the orientation of the FFC bundle, as it has a double-sided glue or tape that holds it together. Care should be taken to avoid pulling the bundle apart during reassembly. The printhead should be placed upside down and the side cables should be fitted into the clip on the right side of the frame. Then, the printhead can be secured in place with three screws.

Kevin also notes that it is possible to tear the FFC cable if you're not careful. Therefore, it's important to be mindful of the cable when putting it in and out of the printer.

In summary, if you're dealing with a broken printhead, the first step is to check the FFC cables. A burnt pin on the cable can indicate a problem and may need to be replaced.
