Epson L365, L366 Adjustment Program, Service Manual, Parts List

When there is damage to the Epson printer and one or more spare parts are replaced, after the replacement of parts is complete, make adjustments to the printer with the Adjustment Program software. So when one or more printer parts are replaced, so that the new parts installed can work optimally, an Adjustment Program is needed. The main purpose of using the Adjustment Program is so that the print quality of the printer can be maintained when replacing and installing new spare parts.

In the Adjustment Program software, there are two modes, namely:

• Sequential adjustment mode is a sequential adjustment item that must be done when one or more spare parts are replaced (repaired), by selecting the replacement part and then you will get a sequence of adjustments that must be made.

• Particular adjustment mode is where you select the adjustment item you want to make.

There are many adjustment items provided by the Adjustment Program. These customization items have different functions. The following is a list of customization items, their functions, and how to use them.

• EEPROM data copy is to copy adjustment values or the like stored on the old Main Board to the new board when the Main Board needs to be replaced. How to do it:

1)   Please select the item that dose backup.
2)   Click [Backup] button to backup selected data from current main board.
3)   Turn off the printer and replace current main board with new one.

4)   Turn on the printer again and click [Restore] button to save selected data on new main board.

• Initialize Setting is to write sale-destination-specific settings and the serial number into the Main Board after replacing it. And also to set the MAC address as necessary. How to do it:

1)   Please select item that does initialization, and click the [Perform] button.

-  [Initial setting] : Writing initial setting value to EEPROM.
-  [Product Serial No.] : Writing Product Serial No. to EEPROM.

-  [MAC Address] : Writing MAC Address to EEPROM.

2)   Click the [Check] button to read out current setting values.

NOTE : Please don't execute this function when backing up the EEPROM data with EEPROM Data Copy function.

• Initialize PF deterioration offset is to reset the counter or set it to its maximum according to the replaced parts. How to do it:

1)   Click [Initialization] button to reset current PF deterioration value to "Zero".

Example of using Adjustment Program

Printer status: A printer's ink pad is at the end of its service life. Please contact Epson support.

All Epson ink jet products have a limited life due to wear and tear of parts during normal use. At some point, the printer will reach a state where components have reached the end of their useful life and satisfactory print quality cannot be maintained. This is the life cycle of a highly mechanical device such as a printer. You can temporarily clear this maintenance message by using the Epson Adjustment Program software. This utility is used after you replace the waste ink pad.

In the case of "A printer's ink pad is at the end of its service life". If a Utility has been previously used on your printer, it cannot be used again in the same case to minimize the risk of property damage because when this message appears, other printer components have also expired and satisfactory print quality cannot be maintained. The following are two stages of repair that must be carried out.

Step 1.   Replacing the waste ink pad

• Look at the back of the printer. Remove the screws at the bottom.

• Tilt the printer and look at the bottom. Swipe right waste ink pad assy.

• Pull out the waste ink pad assy to remove it.

• Replace the waste ink pad with a new one. It is highly recommended to replace the waste ink pad with a new one. New waste ink pads can be purchased in the market. If a new waste ink pad is not available in the market, an alternative solution, you can clean it, dry it, and reuse it. Make sure the waste ink pad is completely dry before reuse.

•  After the new waste ink pad has been replaced, reinstall the waste ink pad assy. Next we will reset the waste ink pad counter.

Step 2.   Reset the waste ink pad counter

To reset the printer can be done in two ways, namely Sequential adjustment mode and Particular adjustment mode. In the discussion below, we will use the Particular adjustment mode.

1.   After replacing the waste ink pad, connect the printer to the computer with a USB cable, then turn on the printer.

2.   Open AdjProg - Select (1) - Model name: L365 (2) - Port: select USB port Epson L365 (3) - OK (4) - Particular adjustment mode (5)

3.   Waste ink pad counter (6) - OK (7)

4.   To find out the Main pad counter value before resetting, follow the following procedure. Check the Main pad counter (8) - then click Check (9). If the Main pad counter value is equal to 100% or close to 100% then the Main pad counter must be reset to zero. Next we will reset the Main pad counter to zero.

5.   Check Main pad counter (10) - then click Initialize (11). On the computer screen will appear several instructions that you must follow. Follow all the instructions that appear on the screen to completion. After all the instructions are done, press Finish (12) and close the Adjustment Program. Done.

Questions and Answers

Q: There is an error "A printer's ink pad is at the end of its service life" on my printer. If the waste ink pad counter is reset, but the waste ink pad is not replaced or cleaned. Can the printer return to normal?

A: Because the waste ink pad counter has been reset, the printer can be reused, but because the waste ink pad is not replaced or cleaned, in the near future, the waste ink will overflow from the printer because the waste ink pad can no longer hold the waste ink. Resetting the waste ink pad counter becomes effective if the waste ink pad is replaced with a new one.

Q: Error Code: 20000xxx when using the Adjustment Program. What to do?

A: Communication error! Error Code: 20000xxx occurs because the printer is not ready to accept commands from the Adjustment Program because it is still busy processing the previous command.

So when the printer receives the command example Main pad counter - Check, the power light will blink for about 60 seconds. The printer can process the next command example Main pad counter - Initialization after 60 seconds have passed. Communication error! Error Code: 20000xxx occurs because the second command "Main pad counter -> Initialization" is done while the printer is still processing the previous command. So wait for the power light to stop flashing, then run the next command.

When there is damage to the Epson printer and requires replacement of spare parts, after the damaged parts are replaced, then use the Adjustment Program to reset the printer so that it can work optimally with new spare parts. If you are having trouble repairing a faulty printer yourself, we recommend contacting an Epson Authorized Customer Service Center.
