Zebra P1080383-044 — Cover Open Sensor for ZD420T, ZD620T
Thermal transferOriginal Zebra partZD420T · ZD620TService part
The Zebra P1080383-044 is the original cover open sensor spare part for the Zebra ZD420 Thermal Transfer (203/300 dpi) and ZD620 Thermal Transfer desktop label printers — the sensor that tells the printer its cover is open, so it stops printing and reports the condition instead of feeding labels.
Zebra lists it in the official spare-parts catalogues for these printers as item 10, Cover Open Sensor. A failed sensor typically shows up as a printer that reports the head or cover open while it is closed, or does not react when it is opened.
Before you order: Zebra uses two different sensors in this family: P1080383-044 for ZD420 Thermal Transfer (203/300 dpi) and ZD620 Thermal Transfer, and P1080383-011 for ZD410 and the direct-thermal/cartridge ZD420 and ZD620. Check the model on the printer label (a T in ZD420T/ZD620T means thermal transfer) before ordering. The newer ZD421 and ZD621 use different parts.
What's in the Box
- 1 × Zebra cover open sensor (P1080383-044)
- No tools, cables or installation guide beyond what Zebra supplies with the kit
What It Means in Practice
- It is an internal part: fitting it means opening the printer, so it is best done by someone used to servicing Zebra desktop printers — we can arrange that for you.
- If the printer shows a head-open or cover-open error with the cover closed, clean the area and check the latch first; if the error stays, this sensor is the usual next step.
- Keeping a spare sensor on site avoids a printer being out of action for a small part.
What Will Not Work
- Zebra ZD410 and direct-thermal/cartridge ZD420/ZD620 printers — they need P1080383-011.
- Zebra ZD421, ZD621 and ZD411 — Zebra uses different (P1112640-series) parts.
- Other Zebra series (GK, GX, ZT) or other brands.

Frequently Asked Questions
How do I know if my printer is thermal transfer?
Thermal-transfer models take a ribbon and have a T in the model (ZD420T, ZD620T). Direct-thermal models print without ribbon (ZD420D, ZD620D); the ZD420C takes a ribbon cartridge.
Does it fit the ZD421?
No. The ZD421 and ZD621 use different sensors.
Can you fit it for us?
Yes — bring or send the printer and we will arrange the repair.
Singular Expert Insight · Buyer's Guide
Before replacing a sensor, rule out a dirty sensor area or a worn latch — they cause the same error. When the sensor has failed, the right part number matters: the ZD420/ZD620 family uses two sensors depending on print method. Browse our
printer accessories and spare parts for printheads, platen rollers and cleaning supplies.
✓ Buy it if your ZD420T or ZD620T reports cover/head open errors that cleaning does not fix.
✕ Skip it if your printer is direct thermal, cartridge or ZD410, or a ZD421/ZD621.
→ Also consider P1080383-011 for ZD410 and the direct-thermal/cartridge ZD420 and ZD620.
Send us the printer model and serial number from the label on the back and we will confirm the right part before you order.
