Star Micronics 89130940 Replacement Print Head

Overview

The 89130940 is the DP8901D replacement print head assembly for Star Micronics SP300-series label printers. When print quality degrades — thin or broken lines, patchy density, streaking across the label web — the print head is typically the wear component at fault, especially on printers running high daily label volumes. Swapping the head restores print quality without replacing the entire printer, which is the more economical path once a unit is out of warranty. At 0.15 lb, it's a compact field-replaceable part rather than a full mechanism overhaul.

Compatibility

Built specifically for the Star Micronics SP300 series. This is a linerless and standard label-capable print head — confirm your printer is running linerless or standard die-cut label stock before ordering, since head specs are matched to media type. This is not a universal or cross-brand part; it is engineered for SP300 hardware only, so don't attempt to fit it to other Star Micronics printer families.

Installation Notes

This is a service-level component swap best handled by staff already comfortable opening the printer chassis and reseating the print mechanism. The head is rated for standard label and linerless media only — running incompatible stock after installation will shorten its service life the same way the original head wore out. Country of origin is China, and the part carries a 2-year warranty, so retain proof of purchase for any warranty claim.
