Zebra 402420-001 Rev K Printer Motherboard Module DB25 Serial USB Head Motor
The Zebra 402420-001 is the main logic board — or motherboard — for Zebra label and barcode printers. This board serves as the central control hub of the printer, coordinating communication between the host system and the printer's mechanical subsystems including the printhead, stepper motor drive, and paper handling. Revision K of this board dates from the early 2000s and was manufactured and function-tested at the factory.

Applications
Zebra is one of the most widely used brands in barcode and label printing, serving warehousing, logistics, retail, healthcare, and manufacturing environments. The 402420-001 motherboard is a replacement or spare part for Zebra printers in the product family this board supports, enabling repair or refurbishment of printers that have suffered logic board failure. Technicians and repair depots working on Zebra printer fleets commonly source boards like this to return printers to service rather than replacing entire units. The parallel, serial, and USB host interfaces on this board reflect the connectivity options common to Zebra thermal printers of the early-to-mid 2000s, making it compatible with a range of legacy host systems still found in industrial and logistics settings today.
This Zebra 402420-001 Rev K printer motherboard has been inspected and appears to be in good condition. We were not able to functionally test this board. Cosmetically the PCB is clean with no visible corrosion, cracked traces, or damaged components. All connectors — including the DB25 parallel port, DB9 serial port, USB port, and ribbon header connectors for the printhead and stepper motor — appear intact. The board carries a factory test label reading "ABA FCN TEST OK" dated 04/22/03, signed by the technician. Please view our photo set and contact us if you have any questions.
