Precision where every character matters.

A high-yield black MICR toner cartridge designed for compatible HP LaserJet 4000 and 4050 series printers. Ideal for producing checks and other financial documents that require magnetically readable MICR characters.

Purpose-Built Financial Printing

Built for professional check production.

Standard toner can create a check that appears correct to the eye, but it may not produce the magnetic signal required by automated check-processing equipment. MICR toner contains magnetically responsive material designed specifically for printing the character line found along the bottom of checks and other encoded financial documents.

This cartridge provides a convenient replacement for the C4127X/HP 27X cartridge platform while supporting established HP LaserJet 4000 and 4050 series printers commonly used in accounting, payroll, banking, and financial-document environments.

Ideal Applications

Financial documents. Clear, secure, consistent.

Compatible HP LaserJet Printers

Designed for the following HP LaserJet 4000 and 4050 series models:

Product Specifications

Actual yield varies according to check design, MICR-line density, page coverage, print-job size, printer condition, and operating environment.

Important MICR Printing Notice

MICR toner is only one component of a properly configured check-printing system. Successful check production also requires compatible check stock, correctly formatted banking information, appropriate MICR fonts or software, accurate character placement, and a properly maintained printer.

Always print and verify a test document before issuing checks. Magnetic readability, bank acceptance, and compliance depend on the complete printing system and document configuration—not the toner cartridge alone.

Recommended Best Practices

Please verify before ordering.

Confirm your printer model and cartridge number before purchase. This cartridge replaces the C4127X/27X platform and is not compatible with HP LaserJet 4100, 4200, 4240, 4250, or 4350 series printers.
