    Wondering if anyone has been able to bring a Summa DC4 printhead back to life after a "blown pixel" diagnosis.

    I have a DC4sx we just brought in from our warehouse that hasn't been operating for several years I'd like to get back in our shop workflow. Done all the particulars to clean, calibrate, test print this baby and I have a white line about an inch up on the print pass the full width of the print.

    When chatting with Summa online, they said it was a blown pixel in the printhead and I would have to replace the head.

    Suggestions or work around would be much appreciated.

    Did you ever get your machine fixed? I bought a new Summa DC5 6 months ago - It has been nothing but problems ever sense. Waste of 25k. I was sold a damaged printer and mislead by them at the tradeshow.

    I am a bit curious why the wide format thermal resin printer is still called a "Summa" DC5? Summa quit manufacturing and selling the printer when Airmark was bought out several years ago. For North America, all consumables (ribbons), parts and service are handled by Airmark in Seattle. The DC thermal resin printers output high quality graphics when operating at peak performance.

    Hi Brian,

    I wanted to let you know that it is definitely possible to clean the printhead on your DC5. You will need a lint free isopropyl alcohol swab to clean the head and you want to clean it from the front to the back of the printhead. I have attached a pdf document which shows the side of the printhead you will need to clean. Once you complete the cleaning I would also change the cleaning sheet on your optiprint cleaning system and try running a few prints of solid colors that run full span. For example, if you are printing on a 54" wide media your printable area per pass will be 3.79" tall by 50.2" wide so just design a rectangle roughly that size and print a few passes. If the white line is still present in the middle of the print pass after the cleaning then unfortunately the head would need to be replaced.

    Please feel free to email me directly at philj@airmark.com if you would like to pick my brain at all on this process.

    Thanks, Brian!

    Best regards,
