Why choose the genuine HP 903 ink pack
Genuine HP 903 cartridge, 4-color. Ink formulated for the print head of these printers: faithful colors, fast drying, no clogged nozzles. The printer recognizes the cartridge and shows the remaining ink level.
Pack or single cartridge?
The 6ZC73AE bundles 4 4-color cartridges, 300 pages each per color: cheaper than cartridges bought separately, and no running out at the wrong moment.
Printers compatible with the 6ZC73AE
The 6ZC73AE is compatible with 3 HP models (manufacturer list):
- tout-en-un HP OfficeJet Pro 6974 (J7K40A)
- tout-en-un HP OfficeJet 6950 (P4C85A)
- tout-en-un HP OfficeJet 6950 (P4C78A)
Check the exact reference of your printer (label at the back or Information menu); suffixes (dn, dw, fdw, n) are variants of the same series and use the same consumables.
Page yield
300 pages per color per ISO/IEC 24711 (5% coverage per color, letter-type documents). Graphics or photo-heavy pages reduce the actual yield. The cost per page shown next to the price is calculated from the current price and this yield.
Installation and maintenance
Replace with the printer on: open the cartridge door, wait for the carriage to stop, press the empty cartridge to release it, unpack the new one, remove the orange tab without touching contacts or nozzles, insert until it clicks and close; the printer aligns the cartridges if needed. Used cartridges: free return through HP Planet Partners.
Use and tips
The 6ZC73AE suits a lightly used printer (letters, a few documents a week): each cartridge (300 pages) lasts about 3 months at 100 pages per month and about 1 months at 300 pages per month.
Keep the printer plugged in and on: it maintains its nozzles and uses very little power in standby; print a color page every two weeks. Store cartridges in their packaging away from heat and install them before the printed date. At the "Ink low" alert, order; the printer prints until it stops. Genuine cartridges protect the print head and the HP warranty; a cartridge bought for another region is not recognized.
