How to update the EEPROM on the Epson L1800 Main Board, Dump Bin Files, and Programmers needed.

Question:

Flashing EEPROM on the Epson L1800 Mainboard is Working. Will the BIN dump file be available on your site during this process? I can take care of the flashing portion via an EEPROM flasher, but I am unsure what chip to flash. Can you point me in the right direction?

We appreciate you contacting us! I'm sorry for not getting back to you sooner. I don’t know if printer issues are particularly time-sensitive, but I want to provide the most accurate and detailed response possible.

Flashing the EEPROM on the mainboard of the Epson L1800 requires specialized equipment and expertise. Here is a step-by-step process for flashing teardrop moldings.

 

How to Flash the EEPROM of the Epson L1800.

 

BIN dump file: The website does not have a BIN dump file for flashing the L1800 mainboard. This file is specific to the printer model and needs to be obtained from a reliable source, either from the manufacturer or another trusted community member.

 

Flashing the EEPROM: Most users try to flash the board through commercial EEPROM programmers, but the L1800's mainboard is rather picky about what it wants. You aren’t able to implement this with standard, off-the-shelf programmers. However, some protections are built into the EEPROM on the L1800 that commercial programmers can’t override.

The Right Chip and Programmer: You are correct that you first need to identify which particular chip needs flashing. Flashing the L1800 mainboard is more than finding the chip; you must write your programmer. BCH Technologies is working on its own solution, but it's not cheap at $4,700. This solution will let you properly interface with the board and flash the EEPROM without the constraints of standard commercial tools.

Alternative Solutions: If you're hellbent on flashing the EEPROM, look into uncommon programming modes or more advanced hardware related to the L1800 board. Correcting the flashing is crucial, as flashing the wrong firmware can completely ruin the board (bricking it).

 

Standard Programmers Why They Don’t Work

Flashing the L1800’s EEPROM is complicated because the chip is locked and secured. Many commercial programmers do not have the functionality to bypass these protections. Furthermore, some steps, such as connecting/disconnecting the chip, require particular attention to detail to ensure that the EEPROM will be flashed successfully and the board will not be damaged.

 

Further Assistance:

Once there is an error in the printer, dealing with it becomes a challenging task as it is a hands-on service. Unfortunately, we cannot offer remote troubleshooting, recommendations, or support for any potential repairs to your printer. But, on the other hand, we do offer the evaluation and repair of your printer at the local level through our BCH Technologies Printer Repair Service (https://bchtechnologies.com/printer-repair-service) diagnostic facility in your area, and, simply put, we work in a first-come, first-served manner and with high demand, it may take us several weeks before we can even get to diagnosing your printer. We do complete printer repairs or parts serviced, with instructions on how to move forward.

We know that our rates may not be the most affordable. For the DIYers, though, we suggest you YouTube it or visit our YouTube channel homepage (BCH Technologies) (https://youtube.com/@bchtechnologies) for videos on how similar repairs are completed. Learn move specific videos that might help your situation by using the search icon to the right of the word “About”. I’ve been producing content for over nine years, so it’s pretty challenging to recall every video. Still, YouTube’s search tool should allow you to access the most relevant materials quickly.
