If your printouts are faint or have gaps, try these solutions:

necessary.
• The ink pack may be old or low on ink, and you may need to replace it.
• Make sure the paper type setting matches the type of paper you loaded.
• Make sure your paper is not damp, curled, old, or loaded incorrectly in your product.
• Align the print head.
• Adjust the print quality in the product software.
• Clean the paper path.
