If you've encountered the frustrating situation of your TR8620 printer producing completely blank pages when using pigment ink, you're not alone. This issue can be perplexing, but fear not; we've compiled a step-by-step guide to help you identify the problem and find a solution.

Checking the Nozzle: A Crucial First Step

The first thing to do when facing blank pages is to check the nozzle. One user in the forum rightly suggested posting a nozzle check. This diagnostic tool provides a visual representation of how well each ink color is performing. In this scenario, a blank nozzle check suggests a potential issue with the pigment ink, specifically the black pigment.

Interpreting the Nozzle Check Results

Upon examining the posted nozzle check, it becomes evident that the pigment black is not flowing. The contributor correctly points out an electrical problem that may be affecting the pigment circuit. Unfortunately, if the nozzle check shows no signs of pigment ink flow, there is limited action that can be taken to rectify the electrical issue.

Possible Causes and Solutions

1. Faulty Pigment Cartridges:
   • The user mentions using aftermarket cartridges that have worked well in the past. However, these may not be effectively cooling the nozzles, leading to pigment ink flow issues.
   • Solution: Consider trying an alternative brand or supplier for pigment cartridges or switch back to using Original Equipment Manufacturer (OEM) black cartridges.
2. Printer Head Considerations:
   • The conversation hints at the possibility of a malfunctioning print head, especially if the issue persists even with multiple pigment cartridges.
   • Solution: When replacing the print head, consider using OEM components to ensure compatibility and optimal performance.
3. Print Settings Adjustment:
   • While the user has found a workaround by selecting "Photo Paper Plus," this may not be a permanent solution.
   • Solution: Experiment with print settings, ensuring that they are appropriate for pigment ink. Check the printer documentation for recommended settings.

Seeking Alternative Solutions

In cases where the electrical problem persists and pigment ink continues to be problematic, users might need to explore alternative options for black text printing. The suggestion to continue using matte photo paper selection for all black text printing might serve as a practical workaround.

Considerations for Compatible Inks

If you are committed to using compatible inks, it's crucial to find a brand or supplier that ensures effective cooling of the nozzles. Regular maintenance, such as running cleaning cycles, can also contribute to optimal ink flow.

Future Precautions

To avoid similar issues in the future, consider the following precautions:

• Regularly check and clean the printer nozzles.
• Use compatible inks that have proven effectiveness with your printer model.
• Follow recommended print settings for different types of paper and inks.
