Key specifications
Compatible with OKI Microline 5590 and 5591 dot matrix printers
Designed for multi-part forms and continuous stationery
Original replacement component for impact printing mechanisms
How to use
Before installing the new print head, ensure the printer is completely powered off and disconnected from the electrical outlet to prevent any electrical hazards or device damage. Open the printer cover, carefully release and remove the old print head assembly according to your printer model manual, and align the new OKI Microline 5590/5591 print head into the secure mounting position. Ensure it clicks firmly into place and reconnect the ribbon cable securely before closing the printer housing and running a test print.
What to consider before purchase
Verify your exact printer model matches OKI Microline 5590 or 5591
Check the current condition of the printer ribbon and pins before replacing the entire head
Ensure installation will be performed following standard safety precautions for impact printers
Usage recommendations: Inspect the ribbon cartridge regularly and replace it alongside the print head if signs of wear appear, as a worn ribbon can negatively impact print quality and reduce the lifespan of the new hardware component.
