Compatible Printers and Series

This two-pack replaces the HP 45 cartridge with part number 51645A and fits a wide range of HP printers. Supported models include the PhotoSmart 1000, 1100, 1115, 1215, 1218, 1315, P1000, P1100 and P2100 families. DesignJet 700 and 750 series and the Fax 1220 are also listed. Many Deskjet models from the 930 through 995 ranges accept these cartridges.

Target Users and Limitations

Home and small-office users who print text documents and colour photos on the supported HP inkjet models will find this pack convenient. The dye-based ink is formulated for vibrant output on standard and photo paper. Buyers who need pigment-based ink for archival document life should look elsewhere. Offices requiring high-volume supplies beyond the rated yield per cartridge will need larger packs or higher-capacity alternatives.

Page Yield per Cartridge

Each cartridge is rated at approximately 1100 pages based on the industry-standard 5-percent coverage test. This figure lets you estimate how long a pack will last for your typical print volume. If your workload regularly exceeds this yield, you will replace cartridges more often than expected.

Questions about this item

How do I install the HP 45 black cartridge and what step do people often miss?

Remove the protective tape from the printhead nozzles before inserting the cartridge into the carriage; skipping this step blocks ink flow and causes blank pages.

What maintenance will the HP 45 cartridges need after the 1100-page yield is reached?

Replace both cartridges once print quality fades or the printer signals low ink; the dye-based ink cannot be refilled reliably.

What limit appears first during long print runs with the HP 45 dye-based ink?

The printhead nozzles can clog during sustained high-volume printing, requiring a cleaning cycle to restore output.
