Zebra P1112640-019 cap de imprimare

The Zebra P1112640-019 print head is engineered for use with the ZD421D thermal printer and delivers a print resolution of 203 x 203 DPI. It is intended to restore or maintain consistent print quality for barcode labels, receipts and other thermal media compatible with the ZD421D. The component is designed for direct thermal/dye transfer printing systems that require precise thermal element alignment and even heat distribution to produce legible text and scannable barcodes.

Advantages

This replacement print head offers consistent 203 x 203 DPI output, resulting in sharp text and barcode edges. It is manufactured to match the mechanical and thermal specifications of the ZD421D, supporting reliable performance and predictable print results. The part is optimized for uniform heat transfer across the print surface, which reduces banding and prolongs media life when properly installed and maintained.

Suitable for

• Replacing a worn or damaged print head in a ZD421D printer
• Maintaining print quality for barcode labels and shipping tags
• Use in retail, logistics and light industrial labeling tasks
• Applications requiring clear 203 x 203 DPI thermal prints

Key specifications

• Compatible printer model: ZD421D
• Print resolution: 203 x 203 DPI
• Print technology: thermal (direct thermal and/or thermal transfer according to printer capability)
• Form factor: replacement print head sized for ZD421D carriage and connector
• Expected print quality: sharp text and high barcode readability at rated resolution

How to use

Power off the ZD421D and follow the manufacturer’s service instructions to access the print head assembly. Remove the old print head by disconnecting the cable and unfastening mounting screws or clips, taking care to avoid contact with the element surface. Install the Zebra P1112640-019 by aligning it with the carriage, securing fasteners, and reconnecting the electrical connector. After reassembly, run a print head calibration and test label print to verify alignment and print clarity before resuming normal operation.

Recommendations

Use compatible media and inks (if applicable) specified for the ZD421D, perform periodic print head cleaning with approved swabs and cleaning solutions, and avoid touching the thermal element with bare hands. Regular inspection and maintenance extend print head life and sustain consistent 203 x 203 DPI output.
