Common Technical Questions

If you have an RNJet H1+ or H2+, remove the cartridge from the print head and clean it using a lint-free paper towel.
If you have an RNJet 100/200/72/140 or any other system, spray with RNJet cleaner (consult our team for the right cleaner solution) and purge the print head before printing.
Speed and Delay settings control when and how fast your printer fires ink relative to your product's line speed and the photocell trigger position. Getting these right is the most common fix for stretched, compressed or misplaced codes — our technical team can walk you through the correct values for your line, or see our product pages for model-specific guidance.
Use the purge function from the printer's control panel to clear ink through the nozzles before a print run, or whenever print quality drops after idle time. Contact our technical team if you'd like a full walkthrough for your specific model.
Every RNJet printer ships with a 1-year manufacturer warranty. Terms and conditions apply — contact our team for details.
