Troubleshooting Epson L1800 Printhead Slamming and Stuck Wiper Issues

Question

Answer

Resolving the Printhead Slamming Issue

1. Inspect the Fix Cable and CR Sensor
   First, remove the cable and inspect it along with the CR (Carriage Return) sensor for damage. Our website has a helpful video guide that walks you through the process. You can find it here (https://bchtechnologies.com/products/13-pin-page-width-cr-encoder-sensor-csic-ffc-cable-for-epson-l1800-1390-1430-dtf-dtg-printers).
2. Ensure Proper Connection to the Mainboard
   Could you make sure the FFC cable is securely plugged into the mainboard? If the cable routes through an intermediary breakout board instead of directly connecting to the mainboard, please ensure the cable's input and output sides are correctly matched. If everything is properly connected and the issue persists, the problem may lie in the breakout board or the mainboard itself.
3. Test Using Swappable Components
   If you have access to a working mainboard and CR sensor board, you can swap them to identify whether the breakout board or the mainboard is the issue. This diagnostic step will help determine which component is causing the problem.

Fixing the Stuck Wiper

1. Inspect the Capping Station
   A stuck wiper often results from the capping station being out of sync. A detailed guide on troubleshooting and repairing the capping station can be found here (https://bchtechnologies.com/products/video-capping-station-assemble-disassemble-guide-for-l1800-1390-artisan-1430-and-1400).
2. Manually Lower the Wiper
   To lower the wiper, you can manually rotate the capping station pump with a flathead screwdriver or gently flip it down with your finger.
3. Sync the White Carriage Lock
   Ensure that the white carriage lock on the back of the capping station is correctly synced with the wiper, as shown in the video linked above. The wiper will not function correctly if these components are out of alignment.
