When using the Epson ET-7750 for high-quality, borderless prints, some users have encountered issues including the print head hitting the paper, resulting in tearing, misalignment, and distressing noise. Additionally, there have been reports of wheel marks on prints, especially those with dense graphics on regular paper. This article will guide you through the troubleshooting steps to address these common problems with the Epson ET-7750 printer, enhancing your printing experience.

Identifying Common Problems

The main problems reported by users include:

• The printer head striking and tearing the edges of the paper during borderless printing.
• Wheel marks appearing on prints that have heavy graphics and borders.
• Prints on glossy photo paper leading to shredding of paper edges and streaks.
• Operational noise and error codes interrupting printing tasks.

Troubleshooting Steps

1. Paper Quality and Settings: Ensure that the paper used is flat and without defects. Curled or moist paper can exacerbate feeding issues. Use the designated settings for the specific paper type in the print menu. If issues persist, experiment with different brands or types of paper, such as switching from glossy to matte photo paper, which may be less likely to slip or jam.

2. Adjust Print Settings: Sometimes, the ink application can overly saturate the paper, causing it to warp during the printing process. To test this theory, try printing on "draft" quality to see if reducing the ink output mitigates the problem. Adjusting the printer's 'thick paper' setting may also help manage how the printer handles heavier paper stocks.

3. Check Printer Mechanisms: It's possible that mechanical problems could be causing the print head to drag or not lift sufficiently. Check for any visible obstructions or misalignments in the printer's path. Cleaning the print head and ensuring it moves freely can also prevent it from striking the paper.

4. Optimize Paper Feed: The source of the paper feed can impact its alignment and smooth travel through the printer. Test both the rear and bottom trays to determine which provides the best feed for different paper types. For papers prone to curling, flattening or de-curling the paper before printing may prevent edges from lifting into the print head.

5. Modify Printing Margins: If borderless printing continues to cause issues, consider setting a small margin to prevent the print head from reaching the very edge of the paper. This can significantly reduce the risk of tearing and misalignment.

6. Regular Maintenance and Updates: Keep the printer's firmware and drivers up to date. Regular maintenance, including cleaning the internal mechanisms and replacing any worn parts, can extend the life of the printer and improve performance.
