LM-IR300B wire marker ink ribbon – black, 12 mm × 50 m (MAX LM-390/380)

LM-IR300B is a black thermal-transfer ribbon refill, 12 mm × 50 m, for MAX LM-390A, LM-380A, LM-380E wire marking printers. It fits into the LM-RC310 ribbon cassette; when it runs out only the refill is replaced and the cassette is reused.

The LM-IR300B is the black ribbon for the MAX LM-390A, LM-380A and LM-380E generation — printers still in daily use at many plants and panel shops. The 50 m ribbon fits the LM-RC310 cassette.

This is the standard black ribbon for most wire marking on white PVC tube, tape and ID plates. For heat-shrink tube switch to the BP type (LM-IR300BP).

Match the printer generation: LM-IR50 ribbons are for LM-550 printers (LM-RC500 cassette) and LM-IR300 ribbons for LM-390/380 – they are not interchangeable. MAX notes that LM-IR50 ribbons cannot be set in the older LM-RC300 cassette. The LM-3000PRO uses its own LM-IR3015B/W ribbons.

LM-IR300B in practice: right printer, enough ribbon

• Check the model label on the printer: LM-390A or LM-380A/E takes LM-IR300B; LM-550 models take LM-IR50B. The cassettes differ and are not interchangeable.
• A 50 m ribbon covers roughly half a 100 m roll of tube, so busy shops keep two ribbons per roll of tube.
• Heat-shrink tube on LM-390/380 printers: use LM-IR300BP.
• Older printers may print faintly even with new ribbon because of a worn platen roller or dirty head — TOVINA can inspect and service them. When replacing the printer, the LM-550A3 adds PC connection and 110 m ribbons.

Fitting the refill into the cassette

• Hold the take-up core and gently pull the ribbon core to separate the ribbon.
• Press button B to fit the ribbon core and button A to fit the take-up core (lettered side up).
• Turn the take-up core until the ribbon shows ink colour and is taut.
• Load the cassette and close the cover until it clicks.

Tips

• Text faint across the whole line is usually a dirty head: clean it with an alcohol swab before changing ribbon.
• Text broken on one side: check ribbon slack, cover closure and the selected tube size.
• Store ribbons cool, dry and out of sunlight; keep a few months of stock so it stays fresh.
• NO INK RIBBON error and other codes: Maintenance & repair.
