The Epson SIDM Black Ribbon Cartridge for LX-350, 300+ and 300+II is a compatible dot-matrix ribbon designed for black monochrome printing. Its compact housing and specified dimensions (52 mm width, 300 mm depth, 75 mm height) ensure correct fit and alignment in compatible impact printers. Supplied in bulk packaging suitable for higher-volume use, the ribbon is intended for standard single-color printing tasks on continuous and single-sheet media typical for dot-matrix machines.

How to use

Turn off the printer and open the ribbon access cover according to the printer manufacturer’s instructions. Remove the empty or existing ribbon cartridge by releasing any securing clips, then align the new ribbon with the print head and feed path, ensuring the ribbon is taut and correctly oriented. Secure the cartridge in place and close the access cover. Power on the printer and run a test print to confirm correct installation and print alignment. Replace ribbons when print density becomes faint or uneven.

Recommendations

Store cartridges in a cool, dry place away from direct sunlight and strong magnetic fields. For consistent print quality, use the ribbon with the specified compatible printer models and replace cartridges before print output becomes illegible. When handling, avoid touching the ribbon surface to prevent smudging or contamination.
