HP 990A Magenta Cartridge

The HP 990A Magenta Original PageWide Cartridge, part M0J77AN, is a genuine HP ink cartridge designed for PageWide Pro 772dw, 777z and 750dw series printers. It delivers professional-quality colour prints for small to medium businesses that need consistent output. The pigment-based ink uses a 10.1 pl drop size and offers an approximate yield of 8000 pages. This single cartridge helps manage printing costs while maintaining reliable performance.

Operating Conditions

The cartridge operates reliably between 59 and 86 degrees Fahrenheit with a humidity range of 20 to 80 percent RH. These conditions suit typical office environments without special climate control. Storage tolerances are wider, spanning -40 to 140 degrees Fahrenheit at the same 20 to 80 percent RH range. Proper storage within these limits preserves ink quality and cartridge integrity before installation.

Sustained Printing Performance

Under continuous high-speed printing the pigment-based formulation maintains consistent colour density and print quality across the full 8000-page yield. Original HP PageWide cartridges are engineered to deliver professional results at the speeds the printer was built to provide without sacrificing output quality. Anti-fraud technology helps ensure authentic HP performance throughout the cartridge life. Easy-open packaging supports fast replacement so workflow interruptions stay minimal during extended print runs.

Questions about this item

How do I install the HP 990A M0J77AN cartridge in my PageWide Pro 772dw, and what step do people often miss?

Open the printer's cartridge access door, wait for the carriage to stop moving, remove the orange protective cap and pull tab from the new cartridge, then slide it firmly into the magenta slot until it clicks; the step often missed is removing both the cap and the pull tab before insertion.

What maintenance or replacement will the HP 990A M0J77AN cartridge need later?

This is a single-use pigment-based cartridge rated for approximately 8000 pages; when print quality fades or the printer signals low ink, replace the entire cartridge — no separate printhead cleaning or ink refill is required.

What limit appears first during sustained high-volume printing with the HP 990A M0J77AN?

The cartridge will reach its approximate 8000-page yield before any other limit; operating temperature must stay between 59 and 86°F and humidity between 20 and 80% RH to maintain consistent output.
