How to Upgrade Epson L1800/L805 Firmware Using a Bin Dump File and EEPROM Programmer

Question: 
I downloaded the bin dump file for this printer, Epson L1800/L805, but there are no instructions. I still don’t understand why so many files are included, and I can't find a way to upgrade this software. We need your guidance on how to use these files and upgrade the firmware.

How to Use the Bin Dump File and Upgrade Your Epson L1800/L805 Printer

You have a bin dump firmware for your Epson L1800 or L805 printer, but you're confused about how to upgrade the firmware. The bin file you received may be used to reprogram the printer’s EEPROM (Electrically Erasable Programmable Read-Only Memory). The process necessitates specialized hardware and, in most cases, specialized firmware software. Next, let me guide you through some steps to simplify EEPROM programming.
 
Prepare the Necessary Tools
Steps to Upgrade Firmware of Epson Printer using Bin Dump File: Have these materials with you.

• EEPROM Programmer: This may be the CH341A, TL866II Plus, or other compatible EEPROM programmer.
• EEPROM Chip: The firmware-specific EEPROM chip in the printer
• Computer: The PC or laptop with the EEPROM programmer software installed.
• Bin Dump File: The firmware file you downloaded in. bin or—hex format.
• Adapters connect the chip to the programmer (especially if it is a smaller or specialized model).

Programmer Software Installation
Before starting, you must install the EEPROM programmer software on your PC. Ensure the software is compatible with your operating system:

• Go to the manufacturer’s website and download the software or drivers for your EEPROM programmer.
• When the installation asks you to restart your computer, click Restart.

Connect the EEPROM Programmer
Now that you have the software installed:

• Take your USB cable and plug the EEPROM programmer into your computer.
• Launch the programmer’s software, which should recognize the device and show its status.

Insert the EEPROM Chip

• Mark Pin 1 of the EEPROM chip by finding the notch or dot on one side, then orient the EEPROM chip accordingly.
• You can insert the EEPROM chip into the programmer's socket, making sure that Pin 1 of the EEPROM chip corresponds with Pin 1 of the programmer.
• If using an adapter, please ensure it is on both the EEPROM chip and the programmer.

Detect the EEPROM Chip
Choose the "Detect" or "Read Device" option in the software to ensure that the programmer detects the EEPROM chip. If it doesn’t show up, ensure that the chip is seated straight and in the right direction and that you use the right model in the software.
(Optional) — Back-Up Existing Data
As always, it is suggested that you save the current EEPROM data before you do anything. In the programmer software, click the “Read” or “Backup” button to copy the existing firmware to a file on your computer. Please save the file and name it EEPROM_backup or something similar. Bin so that you can easily reference it later if you need it.
Load the Bin Dump File

• Once the backup is finished, you may load the new firmware.
• Select the.hex file with the programmer software by selecting the Load/Open File option. Then, choose Bin or Path to the hex file you want to upload to EEPROM.
• Could you make sure the file is loaded? Some software might let you see the file’s contents.

Program the EEPROM
Click on Write/Program to begin firmware programming. Depending on the file size, this step may take a few seconds to a few minutes.
Verify the Programming
After programming, click the "Verify" option on the software to verify that the data written to EEPROM is precisely the same as the original firmware file. Once verified successfully (no errors), you can take the EEPROM chip off the programmer.
Remove the EEPROM Chip
Turn off the programmer and gently pull the EEPROM chip out. Replace the chip with the printer motherboard/ main circuit board, or if this is the EEPROM that needs to be replaced, proceed with the sign now.
Install the EEPROM Chip Back in the Printer
After finishing the firmware upgrade and correctly burning/reprogramming the EEPROM chip, you need to reinstall the chip into your printer’s mainboard or motherboard. Ensure the chip is the right way round and fits nicely into the socket.
 
Troubleshooting Tips:
If you have problems with the programming process, please check the following:

• Do they do a chip check (that is, verify that the chip is the proper one for that particular programmer)?
• Could you ensure you selected the correct chip model in the software?
• Could you ensure the programmer's pins are in good contact with the EEPROM chip?
• If the EEPROM is write-protected, refer to the chip’s datasheet (found at manufacturer websites) and disable the write-protect feature (usually done by grounding specific pins).

After carefully following these instructions, you should be successfully programming the EEPROM and the upcoming update of your Epson L1800 or L805 printer. [Note: Be careful not to touch the sensitive electrical components, as static or other damage can occur. 
 
NOTE: Troubleshooting a printer is a physical task, which can complicate printer troubleshooting. We do not offer remote diagnosis, suggestions, or printer repair assistance. Our method involves a diagnostic evaluation in our local diagnostic center (BCH Technologies Printer Repair Service) and on-site repair. We work on a first-come,e first-served basis because of the high demand, so it may take a few weeks to accept your printer for repair. We'll be able to repair a complete printer or spare components, along with clear steps to take. However, as we know, our rates are not competitive. So, we encourage you to do it on your own over the Internet. Check our YouTube channel (BCH Technologies) and use the search function on the right side of the menu to explore if we have addressed your question in any recorded videos until October 2023. Every day, I receive many coming-of-age questions on specific topics, and while I’ve made a lot of videos in the last nine years, it’s often most expedient to use the search function on YouTube and find solutions. YouTube can also recommend other helpful-looking videos from different channels.
Again, thank you, and we hope this helps you upgrade your printer firmware!
