Product Description

Original or Compatible Sato CL4NX 203dpi thermal Printhead
This is the 203 dpi thermal printhead for SATO CL4NX and CL4NX Plus industrial label printers, supplied as an original or compatible unit to fit the machine you already run. Before ordering, confirm three details against the printer you are servicing: the printer model (CL4NX / CL4NX Plus, 4-inch), the resolution (203 dpi / 8 dots/mm) and the part number of the head being replaced (reference R29797000). Matching those three is what decides whether the head seats correctly in the existing bracket without re-configuring the printer.

Principal Benefits
Built for the service engineers, distributors and OEMs who have to keep CL4NX printers running in production.
Barcodes That Read First Time:
At 203 dpi the head lays down stable, well-defined bars and text, so the labels your customers scan on a line or in a warehouse read cleanly instead of bouncing back as no-reads.


Downtime Measured in Minutes:
A head change is a service job, not a rebuild. The tool-free, snap-in design lets you or your end customer return the printer to production quickly instead of holding up a shift.
Service Life Under Industrial Load:
Built for the duty cycle of the CL4NX range, with consistent heat distribution that keeps output steady across the thermal transfer and direct thermal work a production printer sees.


Keeps Pace at Full Speed:
Supports print speeds up to 14 inches per second at 203 dpi, so batch production stays fast without compromising legibility.
Maintenance and Pairing After You Fit It
On a CL4NX running production volume, the printhead usually wears out long before the printer does, and when it does, two things decide how long the next one lasts: the thermal transfer ribbon it is paired with, and the head pressure and alignment after fitting. Codewel has manufactured thermal transfer ribbon since 2003 and printheads are one of our core product lines, so we can advise on matching head and ribbon instead of selling you a part on its own. Stay with 203 dpi and the ribbon grade your job was set up for, and re-check the pressure whenever a head is changed.

Why Buy the Sato CL4NX 203dpi Thermal Printhead from Codewel
Two Decades of Printhead Engineering:
Hangzhou Codewel New Material Co., Ltd. has manufactured thermal transfer ribbon since 2003, and printheads are one of our core product lines. That is roughly 20 years of printhead engineering behind what we supply, supported by more than 50 patents and ISO 9001 / RoHS / CE certification.
Ribbon and Printhead Matched Together:
Because we make both the ribbon and the printhead, we can advise on pairing them for your application - the kind of guidance a parts-only seller cannot give.
Built to Supply the Trade:
We work with distributors, printer service companies and OEM integrators rather than chasing one-off retail orders, and we ship to Europe, the Americas, Southeast Asia and the Middle East.
Production Scale for Repeat Orders:
A 6,000+ m² production base and a 100+ person team sit behind every head we ship, so stocking programmes and repeat volumes are not a problem.
Confirm the Fit Before You Order
This listing covers both original and compatible heads, so please tell us which variant you need. To quote accurately and ship the right part first time, send us:
- Your printer model - SATO CL4NX or CL4NX Plus - and confirmation that it is a 4-inch, 203 dpi machine
- The part number printed on the existing printhead (reference R29797000), and a photo of the old head if you have one
- Whether you need an original or a compatible unit
- Required quantity, and whether this is a one-off replacement or a stocking order
- Label size, ribbon type and the application the labels go into
Not sure which head fits? Send us your printer model or a photo of the existing printhead and our team will confirm the correct 203 dpi replacement for your CL4NX.
