Printhead for Zebra ZM400

This 305dpi thermal printhead is a direct replacement for the Zebra ZM400 barcode label printer. It restores sharp output for shipping labels, asset tags and compliance stickers in warehouse or manufacturing lines. The part matches the original 79801M specification so the printer retains its factory resolution and speed. Buyers needing a different resolution or a printhead for another printer model cannot use this item.

Single unit in protective packaging

The box contains one A+ quality printhead sealed to guard the heating elements from dust and static during transit. No cables, mounting brackets or firmware media are included because the ZM400 reuses its existing harness and calibration data. Installers simply swap the old head, run the printer’s built‑in alignment routine and resume work. Shops that expect a full service kit with rollers or cleaning supplies will need to source those separately.

Aluminium housing with spring‑loaded mounting

The printhead sits in a rugged aluminium carrier that bolts into the ZM400’s existing hinge and latch points without modification. Gold‑plated edge contacts mate with the printer’s flex cable for reliable 220V signal transfer across millions of labels. The spring‑loaded pressure system maintains even darkness across the 305dpi width, reducing reprints caused by fading edges. Environments requiring waterproof or chemically sealed printheads should verify compatibility before purchase.

Questions about this item

How often will the 305dpi printhead need replacing under normal label volumes?

The 79801M printhead is a consumable part; replacement timing depends on label throughput and media abrasiveness, but the supplier covers defects for 90 days from purchase.

What component reaches its limit first during continuous printing on the ZM400?

The thermal elements on the 305dpi head degrade with sustained heat cycles, so print quality fade on long runs is the first practical limit.

How much heat and power does the 220V printhead generate during all-day operation?

The head runs on 220V supply; expect noticeable warmth near the print line during extended shifts, but no active cooling is built into the module itself.
