The HP 507A Cyan LaserJet Toner Cartridge, part number CE401A, delivers vivid, consistent color output for HP Color LaserJet Enterprise 500 series printers, including the M551 and M575 lines. Engineered for demanding office environments, the cartridge relies on HP ColorSphere toner technology, a fine spherical particle formulation designed to melt and fuse evenly onto the page, producing sharp text edges and smooth color gradients across marketing collateral and everyday correspondence. The cartridge is housed in a rigid contract channel enclosure featuring a factory sealed toner chamber and an integrated drum protection shutter that shields the photosensitive drum from ambient light and dust until installation. Rated for approximately 7800 pages at 5 percent page coverage, this optimized high yield variant extends the interval between replacements well beyond the standard 6000 page retail version, reducing supply changeovers in busy shared print rooms. The cartridge installs directly into the toner bay without manual filling, priming, or calibration, and the printer's internal sensors automatically recognize the installed unit to manage toner level reporting and print quality adjustments. Consistent color calibration across the cyan, magenta, yellow, and black set supports accurate, repeatable color matching for branded documents, while the cyan formulation anchors cool tones and shadow depth within mixed color print jobs. Facilities managers gain predictable per page costs when standardizing on genuine HP supply chains instead of third party alternatives.
