Zebra P1004237 300 dpi Printhead for 170Xi4
Genuine Zebra300 dpi170Xi4 · ZE500-6Replacement printhead
The Zebra P1004237 is the genuine 300 dpi replacement printhead for the Zebra 170Xi4 6-inch industrial label printer, also listed by Zebra for the ZE500-6 print engine in right-hand and left-hand versions. It is for production and logistics sites whose 300 dpi labels show white lines, faded areas or barcodes that no longer scan.
The printhead forms every dot on the label. Over time abrasive media, ribbon edges, dust and high darkness settings burn out heating elements, which shows as fine vertical voids. A new head restores sharp, even print across the full width, which matters most for small text and dense 2D barcodes at 300 dpi.
Before you order: This head is for 300 dpi 170Xi4 printers and ZE500-6 engines only. A 203 dpi 170Xi4 needs P1004236. The 110Xi4, 140Xi4 and 220Xi4 use different heads. The resolution is shown on the printer configuration label.
What's in the Box
- Zebra 300 dpi printhead for 170Xi4 / ZE500-6 (1 pc)
What It Means in Practice
- Matching the resolution keeps your label layouts at the correct size and barcode dimensions.
- A new head removes white vertical lines that cause barcodes to fail scanning or verification.
- Clean the head regularly and keep darkness and pressure as low as the job allows to extend its life.
- After fitting the head, run media calibration and a test label.
What Will Not Work
- It does not fit the 110Xi4, 140Xi4 or 220Xi4, which use different heads.
- It will not work in a 203 dpi 170Xi4; that printer needs P1004236.
- It is not suitable for the newer ZT600 series printers.
- It will not fix platen roller, sensor or ribbon drive faults.

Frequently Asked Questions
How do I confirm my printer is 300 dpi?
Print a configuration label or check the model label on the printer. It shows 203, 300 or 600 dpi.
Can this head convert a 203 dpi 170Xi4 to 300 dpi?
Changing resolution needs the Zebra conversion procedure, not only a different head. Ask us and we will check the right kit.
Does it fit the ZE500-4 engine?
No. The ZE500-4 is a 4-inch engine; this head is listed for the 6-inch ZE500-6.
Singular Expert Insight · Buyer's Guide
Xi4 printers are built to run for years, and the printhead is the part that wears. Matching model and resolution is the key: the 170Xi4 comes in 203 and 300 dpi, and the heads look similar. Get the configuration label first and the order is right first time. See more genuine parts in our
printer accessories range.
✓ Buy it if you run a 300 dpi Zebra 170Xi4 or ZE500-6 engine and labels show white lines or faded barcodes.
✕ Skip it if your 170Xi4 is a 203 dpi unit, or your printer is another Xi4 width or a ZT600.
→ Also consider Zebra cleaning pens or cards to keep the new head in good condition.
