V4ink 42A Q5942A MICR toner for LaserJet

This aftermarket black MICR toner cartridge replaces OEM Q5942A and is built for HP LaserJet 4240, 4250 and 4350 series printers. It targets offices that print cheques or other magnetic-ink documents and need a compatible supply with a 10000-page yield. Buyers who require colour output or a different page yield should look elsewhere.

Single black cartridge in the box

The package contains one black toner cartridge and no additional hardware, chips or software utilities. Specially formulated toner is designed to deliver consistent magnetic signal strength for MICR readers while maintaining standard text quality. The formulation follows STMC and ISO factory standards and the facility holds ISO9001 and ISO14001 certifications.

Drop-in installation for listed LaserJet models

Installation follows the standard cartridge swap procedure for the compatible LaserJet 4240, 4250 and 4350 models; no tools or firmware updates are required. Common issues include forgetting to remove the sealing tape before insertion, which causes blank pages, and using the cartridge in non-listed printers where fit or MICR readability cannot be assured.
