Solutions for Single Nozzle Clog

General

I am working on converting an Epson 7900 to Piezography Pro ink set and am fighting with getting one nozzle to clean per attached nozzle check pattern. This is ink slot #5 or Matte Black (MK) on Epson ink set and UltraHD Matte Black on Piezography Pro ink set. I’ve run multiple cleanings with PiezoFlush, manually cleaned print head using paper towel under the ink head with both PiezoFlush and Windex but simply cannot get this one nozzle clear. The printer was purchased 12/2011 and has only had 465 pages run on it so it has sat more than it has run at this point in its life. The following are ideas I’ve come up with as solutions based on research I have done but would love some input/guidance on others experience and recommendations.

  1. Attempt Tip #3 in support on how to clean printheads found on inkjetmall site where I manually pull PiezoFlush through the head using a syringe.

  2. Operate the printer as a 10 ink setup rather than 11 ink and (as I understand it) not use that ink slot.

  3. Contact Epson support, which there is a local support location in my region, to see about having them out to service the issue.

I appreciate any and all responses. Thank you.

That particular nozzle check indicates what appears to be a head delimitation in that position, so 10 ink Piezography printer rather than an 11 would be my vote!

Thank you Rachel.

Am I able to decide which ink to eliminate from my set, ie I plan to print neutral to cool tone rather than warm tone black and white prints. With that said, is there a process to set up accordingly.

Thanks again.

Hello Chipper,

You would need purchase the 9 bottle set of Piezography Pro. The 9 ink bottle set eliminates the VLG in both Warm and Cool tones. Piezography provides support for your printer as either a K5 11 ink set or K4 9 ink set! You would choose the K4 install command when you install Piezography curves.

Let me know if you need any additional help.

I have already purchased the full 11 ink set and installed software based on that setup. If there is any documentation to setup the 9 ink set instead please share a link.

Thank you.
