Tech Overview: Epson SC-P600 Error 0x44 After Printhead Cleaning

Printers, especially high-quality models like the Epson SC-P600, occasionally face issues with clogged nozzles, prompting users to perform maintenance tasks such as printhead cleaning. Recently, users reported encountering the dreaded Error 0x44 after attempting to clean the printhead on their Epson P600 printers.

The Cleaning Technique

The users utilized the waterfall technique, employing a cleaning solution consisting of 20% isopropyl alcohol, 3% propyl glycol, and 77% distilled water. This method involves pushing the solution through the ink inlet pins using a syringe. While effective in the past, this time, complications arose after reassembly.

The Error and Initial Troubleshooting

Upon turning on the printer post-cleaning, the printer initiated an initial cleaning cycle, ejecting ink onto the waste pad. However, the process abruptly halted, and the printer shut down, displaying Error 0x44 upon restart. Suspecting a ribbon cable issue, the user dismantled and reassembled the printer, but the error persisted.

Exploring Error 0x44

Error 0x44 was unfamiliar to the users, leading them to seek information on its meaning and potential causes. One reference, albeit for the P400 model, suggested a communication error between the printhead and the main board, possibly indicating main board failure.

Possible Causes and Solutions

To pinpoint the issue, one user, Photix, contemplated checking the voltage levels between specific ribbon cable pin connectors to verify the printhead's integrity. If the printhead proved functional, the user speculated a main board failure, possibly a burnt fuse. The plan involved ordering a replacement fuse, possibly from BCH, and performing the necessary soldering.

Community Collaboration

The users engaged in a collaborative effort, sharing their experiences and troubleshooting steps. Murat expressed concern over the complexity of potential printhead issues, emphasizing the collective hope for a straightforward solution like a fuse replacement.

Recent Insights

A user suggested inspecting the harness connection to the printhead, noting that the ends of the connection covered with aluminum foil might be eroded. This erosion could impede communication between the printhead and the printer, potentially contributing to Error 0x44.

Conclusion and Call to Action

As the Epson SC-P600 users continue their collective exploration to resolve Error 0x44, insights from the community may shed light on effective solutions.
