Compatible Printhead for Zebra ZM400 and RZ400

This OIAGLH 79801M thermal printhead serves as a direct replacement for Zebra ZM400 and RZ400 printers. It supports a native resolution of 305dpi for clear barcode and label output. The part is supplied new and carries a 90 day warranty period. Maintenance teams and operations managers can use it to restore print quality on existing hardware.

Sustained Print Performance

The printhead operates on both 110V and 220V power inputs, matching the printer's electrical requirements. It maintains consistent dot placement during long label runs without drift. Thermal elements are rated for the standard duty cycle of the ZM400 and RZ400 platforms. Users should monitor ribbon tension to avoid premature wear on the heating line.

Installation Notes and Common Issues

The unit fits the existing printhead carriage and connects via the original cable harness. No firmware update is required after installation. A frequent issue is misalignment of the pressure rollers, which causes uneven print density across the label width. Clean the platen roller and verify the head latch is fully seated before running a test print.
