Setup, Compatibility & Care
Compatibility: This ribbon is specifically manufactured for the OKI Microline (ML) 520 and ML 591 impact printers. Verify your printer model number before installation to ensure the ribbon deck matches the 8mm width standard.
Installation Steps:
- Power off the printer and open the front cover.
- Locate the existing ribbon cartridge and release the locking tabs to remove it.
- Carefully slide the new Alpa-Cartridge ribbon into the drive mechanism.
- Thread the ribbon through the print mask (the metal guide in front of the printhead).
- Manually turn the tension knob on the cartridge to remove any slack in the fabric.
- Close the cover and perform a test print to confirm smooth movement.
Care: Store unused cartridges in a cool, dry place out of direct sunlight to prevent the ink from drying out. Keep the sealed packaging intact until you are ready for immediate use.
