HP 937 Yellow Original Ink Cartridge · ~800 Pages · 10 ml · for OfficeJet Pro 9100/9700

The HP 937 Yellow Original Ink Cartridge (4S6W4NE) is a genuine HP yellow cartridge for the HP OfficeJet Pro 9110b, 9120b, 9130b, 9120e, 9125e, 9130e, 9135e, 9720 and 9730. HP rates it at approximately 800 pages under ISO/IEC 24711 or HP testing methodology, tested in the HP OfficeJet Pro 9100 series.

Each colour in this system is a separate cartridge, so you replace only the colour that has run out — practical for offices that print mostly one colour, such as blue logos or yellow highlights.

• 1 x HP 937 Yellow ink cartridge
• Cartridge sealed in its protective packaging until use
• No printer, cable, paper or printhead included

• The 800-page figure comes from a standard test with continuous printing of a mixed document set. Plain text documents usually go further; full-page colour, photos and many short print jobs use more ink.
• Because each colour is a separate cartridge, the printer will tell you which one is low and you replace only that one — keep a spare of the colour you use most.
• Keep the cartridge sealed in its pack until you install it, store it at room temperature, and install it promptly once opened so the ink does not dry at the nozzles.
• If you print a lot, compare with the higher-capacity version: HP 937e EvoMore Yellow is the high-capacity version.
• A low-ink warning is an early alert: you can usually keep printing for a while, so order the replacement when it appears instead of waiting for the cartridge to run completely empty.
• After installing, print the printer's print-quality or test page once to confirm every colour is printing cleanly before a long or important job.

• Printers that use HP 963 cartridges — the shape and contacts are different, so it will not fit or will not be recognised.
• Refill kits or ink bottles: this is a sealed original cartridge, not an ink tank system.
• Other colours: this pack contains yellow only — the other colours of the 937 system are bought separately.
• It does not include a printhead — the printhead stays in the printer and is not replaced with the cartridge — and it will not fix print faults caused by a damaged printer.
