The HP 36A (CB436A) is the original HP black LaserJet toner cartridge for the HP LaserJet P1505 printer and the LaserJet M1120 and M1522 MFP series, monochrome machines still widely used in small offices and at home. It is a standard-yield cartridge rated for about 2,000 pages (ISO/IEC 19752) and combines the toner and imaging drum in one unit, so replacing it effectively renews the main print components. HP's toner gives sharp black text and graphics, and the cartridge's built-in intelligence reports toner level to the printer so you can plan replacements. Original HP cartridges are designed to run at the printer's rated speed without the leaks, streaks or early failures sometimes seen with remanufactured toner. The box contains the toner cartridge and a recycling guide, and empty cartridges can be returned through HP Planet Partners where available. The boxed cartridge measures roughly 375 x 113 x 125 mm and weighs about 600 g. Store between -20 and 40 degrees C; operate between 10 and 32.5 degrees C.
