Product Description

Replacement thermal printhead for the Zebra 105SL, 300 dpi, model G32433M and part number KPA-106-12MTA4-ZB4. The 105SL has been in service for decades as a mid-volume industrial printer, and this head is the wear part that eventually decides print quality. It mounts on the original carriage and uses the machine's existing connector, so no adapter or firmware change is involved.
Principal Benefits
Why it matters
The correct cross-reference
G32433M crosses to KPA-106-12MTA4-ZB4, the head specified for the 105SL. Ordering by the head number rather than by printer name avoids the connector and bracket differences that come with a near-match.
300 dpi keeps barcodes readable
At 300 dpi, dense Code 128, small human-readable text and 2D codes stay inside scanner tolerance. This is the resolution most 105SL users need for compliance labels.
Uniform density edge to edge
The heating elements are specified for even output across the full web, so labels printed at the outer edge of the liner match those in the middle instead of printing faint.

Fits without modification
Mounting holes, connector position and ribbon path follow the original part. A technician can swap the head with the standard tools already used on the machine.
No media re-qualification
Wax, wax-resin and resin ribbons already running on the 105SL continue to work. Nothing about the label stock or ribbon grade has to be re-approved after the change.
About Codewel
About Codewel

A printhead and media supplier
Codewel has been supplying thermal printheads and the consumables that run through them for industrial label users. Most 105SL enquiries arrive as a part number from a maintenance schedule or a photograph of a worn head, and we confirm the fit from that before quoting. Heads ship from stock held for common Zebra models rather than being ordered in per sale.








Why Buy Printhead From Us
What you get
Matched on the head number, not the printer name
A 105SL can carry more than one head variant depending on build year and options. Send the number stamped on the old head and we match that, rather than shipping whatever the model name suggests.
Genuine or compatible, stated plainly
Some maintenance programmes require a genuine Zebra part; others are keeping an older machine productive at lower cost. We quote both and say which one is in the box.

Powered up before packing
Each head is checked on compatible equipment and packed in anti-static material inside a rigid carton. A bent connector in transit is the usual reason a new head arrives dead.
Head, ribbon and labels in one shipment
Consolidating the head with the ribbons and labels it will run on keeps maintenance under one freight charge and one set of export documents.
Before you order
Read the number on the old head, or send a clear photo of it. Confirm 300 dpi on the machine plate as well, because the 105SL was also built at other resolutions. We check both, quote with freight, and ship after you approve.
FAQ
What resolution is this printhead?
300 dpi, about 12 dots per millimetre. It is the resolution used for compliance labels, dense barcodes and small text on the 105SL.
Does G32433M fit every Zebra 105SL?
It fits 105SL machines built for the KPA-106-12MTA4-ZB4 head. Because the 105SL was produced over a long period with different configurations, the number on the existing head is the reliable check.
How do I know the head needs replacing rather than cleaning?
Clean the element line first with a lint-free swab and approved cleaning fluid. If voids, vertical streaks or a faint band remain in the same place after cleaning, the element is damaged and cleaning will not recover it.
Can I fit it myself?
Yes, if you are used to working on the machine. Power down, release the printhead latch, disconnect the ribbon cable and transfer the mounting hardware. Handle the element by its edges only.
