Troubleshooting Epson L1800 DTF Printer: Ink and Paper Lights Flashing Issue

Question:
I recently replaced the print head carriage and capping station on my Punehod L1800 DTF printer, and it has been printing fine. However, when I attempt to perform a head cleaning, both the ink and paper lights immediately start flashing red simultaneously. Could you suggest what might be causing this issue?

Answer:

Regarding your issue with the Epson L1800 DTF printer, the simultaneous flashing of the ink and paper lights typically indicates an internal error that the printer detects during maintenance routines, such as head cleaning. Several potential reasons could trigger this error:

1. Incorrect Installation or Alignment:
   Since you recently replaced the print head carriage and capping station, verify that both components are installed correctly and aligned properly. Even slight misalignment can trigger sensor errors.

2. Sensor Malfunction:
   Specifically, an APG (Auto Platen Gap) sensor error or CR (Carriage) encoder sensor issue could be causing the lights to flash. These sensors ensure proper positioning and spacing during printhead maintenance and printing.

To pinpoint exactly what the problem might be, we recommend using Epson’s specialized diagnostic tool known as the Adjustment Program. This software allows you to access detailed error codes which can significantly narrow down the cause of the issue. Here’s how you can use it:

• Open the Adjustment Program and select the USB port showing your printer’s name from the dropdown menu.

• Choose Particular Adjustment, then scroll down and select Printer Information Check.

• Click Check, and the program will display the latest error code at the top, typically labeled as error number one.

To interpret the error code you see, search "BCH Epson Error" on Google. This will direct you to our detailed page explaining Epson’s Triple Secret Error Codes. For example, errors like the APG sensor error (indicating problems with automatic platen gap adjustment) or CR encoder sensor errors (related to the carriage positioning) may appear, helping you better understand the specific issue.

If you need visual guidance on using the Adjustment Program, we have created a quick instructional video available on our YouTube channel: Epson Adjustment Program Guide.
