Troubleshooting Initialization Issues in Epson L1800 with a 1390 Board

Question

I've been trying to substitute a 1390 board into my Epson L1800, but I'm encountering a persistent problem: the printer cannot initializes, moving the head from right to left and then lifting, but then it enters a continuous loop of initialization without completing the process. Have you encountered such an issue before, and if so, how can it be resolved?

It sounds like you're experiencing a challenging issue with your Epson L1800. Based on the behavior you described, there are a couple of potential causes and solutions to consider:

1. Firmware Issues: The problem might stem from the firmware inside the EEPROM chip. Similar to a computer's hard drive, the EEPROM can degrade and cause erratic printer behavior, such as the initialization loop you're witnessing. If you have access to an adjustment program, try flashing new EEPROM data onto the chip. This process might resolve the issue by relocating the data to a healthy section of the EEPROM.
2. CSIC Data Configuration: The use of a 1390 board typically requires the integration of chipped cartridges. It's necessary to ensure the CSIC data is correctly fed into connection CN15 on the mainboard. Some printer modification companies alter the CSIC board to bypass standard configurations, utilizing an overwrite board placed on top of the OEM CSIC board. An overwrite board will look like this picture.

   

   If obtaining such a modified board is challenging, you could try using self-resetting cartridge chips. This method involves removing the chips so the printer does not detect any installed cartridges, then starting the printer. Once the ink lights activate, press the ink button until the carriage moves to the capping position. At this point, insert the cartridge resetter, press the ink button again to finalize the initialization. This workaround can trick the system into completing the start-up sequence.
