Epson WF-R4640 Error 0x85

The Epson WF-R4640 printer may sometimes display an error code 0x85, accompanied by a message indicating a PWM duty error or PIS failure. These errors can be frustrating when you need to print something urgently. However, understanding the problem and exploring potential troubleshooting steps can help you overcome it.

When the printer encounters a PWM duty error, it implies that there is an issue with the pulse width modulation (PWM) duty cycle, which controls the speed of the print head. On the other hand, a PIS failure refers to a problem with the Print Image Sync (PIS) mechanism, which ensures the synchronization between the print head and the image being printed.

To troubleshoot this error, start by turning off the printer and disconnecting it from power. Wait for a few minutes before plugging it back in and turning it on again. This simple step can sometimes resolve minor glitches or temporary issues causing the error.

If the error persists, consider updating the printer’s firmware to the latest version. Manufacturers often release firmware updates to address known issues and enhance performance.

Additionally, check for any loose connections between the printer and the computer or other devices it is connected to. Ensuring a secure and stable connection can eliminate any communication disruptions that could trigger the error.

If these steps do not resolve the issue, it is recommended to contact Epson customer support or refer to the printer’s user manual for further assistance. Their expert guidance can help identify the underlying problem and recommend specific solutions.

By following these troubleshooting steps and seeking professional help if needed, you can overcome the Epson WF-R4640 error code 0x85, allowing you to continue with your printing tasks smoothly.
