How to Fix "Open Paper Tray" Error on Epson Artisan 1430

Question:

I have an Epson Artisan 1430 that I converted and it worked great. However, after sitting unused for six months, I cleared the printhead but now it displays "open paper tray" when I try to print. The paper tray is open and I can't find any information on how to fix this error. Any suggestions?

The "open paper tray" error on the Epson Artisan 1430 can indeed be frustrating. This issue often stems from the printer's PW (Paper Width) sensor or the CD/DVD tray lock mechanism. Let's delve into the details to troubleshoot and resolve this problem.

Detection and Function of the PW Sensor: Before starting to print, the PW sensor detects the edges of the CD-R. It determines the type of media and performs dark voltage measurements to calculate whether paper is present. Here’s a detailed breakdown:

• Dark Voltage Measurement: This occurs on the CD/DVD tray to establish a threshold value (VS) saved in the EEPROM.
  • White Level Detection: If the white level measurement is close to the PW detection level, it indicates the sensor might be dirty or deteriorated.

Steps to Address the Error:

1. Clean the PW Sensor:
   • The sensor might be dirty, affecting its ability to detect the paper correctly. Clean the PW sensor gently to ensure it functions properly.
2. Check the CD Tray Base Lock Mechanism:
   • The printer locks the CD/DVD tray base to prevent damage to the printhead. If this mechanism fails, it could cause the "open paper tray" error.
   • Lock Release Sequence:
     1. When the Carriage Unit returns to its home position, the Pump Motor drive activates the Paper EJ Lock Release Cam.
     2. This cam presses down the Paper EJ Transmission Lock Lever, releasing the CD/DVD tray base.
3. Verify Connections and Sensor Condition:
   • Ensure that the PW Sensor FFC (Flat Flexible Cable) is correctly routed and not in contact with any parts.
   • Check that the FFC is connected to the CR Encoder Board and PW Sensor Connector. Any disconnection here can cause errors.
   • Inspect the PW Sensor and its FFC for any damage. If damaged, replacing the sensor may be necessary

Addressing printer issues can be complex due to the hands-on nature of the problems. For instance, resolving a simple clog might involve detailed unclogging procedures. If the printer has been inactive for a while, a comprehensive ink system service might be required. Issues like a "paper jam" can have numerous causes, often becoming an in-office joke. Therefore, we can't offer remote troubleshooting, suggestions, or support for printer repairs.

We provide in-person evaluation and repair services through our local diagnostic facility. Due to high demand, we operate on a first-come, first-served basis, so it may take a few weeks for your turn to drop off or mail in your printer. Our services can repair either the whole printer or specific parts, with clear instructions for mail-in or local drop-off services. However, we recognize that our rates might not be the most economical, so we highly recommend self-help through online research.
