How to Resolve Banding Issues on an Epson Artisan 1430 Printer

When using an Epson Artisan 1430 printer for creating film positives, encountering banding can be a frustrating experience. Banding manifests as consistent, straight horizontal lines across prints, which can be lighter or darker in density. This guide will explain the primary causes of horizontal banding and provide effective solutions to resolve these issues.

Common Causes of Banding and Solutions

1. Nozzle Clogs

Problem: Nozzle clogs are the most frequent cause of banding, resulting in lighter and off-color horizontal lines. These clogs can be due to a dusty environment, infrequent printer use, or a malfunctioning print head.

Solution:

• Run a Nozzle Check: Access this function through your printer’s driver software or directly from the printer menu. Print a test pattern to identify missing lines in the "stair step" pattern.
• Clean the Print Head: If the nozzle check shows missing lines, initiate a cleaning cycle through the software or by holding the cleaning button on the printer. Repeat the nozzle check after cleaning.
• Power Cleaning: If regular cleanings fail, perform a power cleaning found in the maintenance menu of the printer. Refer to your user manual for detailed instructions.
• Contact Epson Support: Persistent clogs may necessitate a head replacement. Reach out to Epson technical support for further assistance.

2. Misaligned Print Heads

Problem: Misaligned print heads, often caused by physical movement of the printer or incomplete software alignments, can lead to darker and off-color horizontal lines.

Solution:

• Head Alignment: Perform a comprehensive head alignment using the printer’s front panel as described in the Epson manual. Avoid software-based alignments as they may be less effective.
• Adjust Print Speed: Disable the high-speed option in the Epson driver or RIP software. You can also enable the “super” setting or select an 8-pass mode in your RIP software to improve alignment.

3. Low-Quality Print Settings

Problem: Printing in low-quality settings can result in pronounced, wider banding due to faster print speeds and reduced ink usage.

Solution:

• Increase Print Quality: Always print at a minimum of 1440 dpi to minimize banding. Adjust your driver or RIP software settings to a higher quality mode, such as "Best Photo."

4. Incorrect Paper Thickness Settings

Problem: Using very thin or thick media without adjusting the printer settings can cause darker and off-color horizontal banding.

Solution:

• Select Correct Paper Type: Ensure the media type in the printer driver matches the paper you are using. For RIP software like Colorbyte’s ImagePrint, choose the closest paper type in the options dialog box.
• Adjust Media Settings: Verify the printer is set to the appropriate media thickness to prevent banding issues.

Additional Tips and Best Practices

• Check Printer Settings: Before printing each film, verify the settings are optimal. Use "Best Photo" and "High Gloss Paper" settings and print composite instead of separations to avoid banding.
• Regular Maintenance: Keep your printer in a clean environment and use it regularly to prevent nozzle clogs.
• Technical Support: If the problem persists despite trying the above solutions, contact Epson technical support for further diagnosis and potential repairs.
