Frequently Asked Questions

• What is in this set of 2?

  The box holds: CC641WN (600 pages), CC644WN (440 pages). Each cartridge is individually sealed.

• Which printers does this set fit?

  The set fits DeskJet D1660, DeskJet D2530, DeskJet D2545, DeskJet D2560 and 28 more. The complete verified list is in the Compatible Printers section on this page.

• Black or tri-color — do I need both?

  The printer needs both slots filled to print. The black cartridge prints text; the tri-color holds cyan, magenta and yellow in one body — when one colour runs out, the tri-color cartridge is replaced as a unit.

• Do these cartridges include the printhead?

  Yes — on this family the printhead is part of the cartridge, so every cartridge in the set brings a fresh printhead with it.

• Do all the cartridges have chips?

  Yes. Every cartridge in the set carries a new compatible chip that reports its own ink level to the printer.

• Is the set better value than singles?

  Yes — the set is priced below the same cartridges bought one by one, and one box restocks every slot at once. Check the per-cartridge yields above against your usage.

• Can I install just one cartridge from the set?

  Yes. Open and install only the colour the printer asks for, and keep the rest sealed — they store fine for when their turn comes.

• My printer shows a warning after installing — what do I do?

  Acknowledge the message, reseat the cartridge until it clicks and restart the printer. Most warnings are a one-time notice that a non-original cartridge was fitted.

• Is the HP 60 the same fit as the HP 901?

  No. They serve different printer generations — the 60 fits the DeskJet F-series, Photosmart C4600/D110 and the ENVY 100, 110 and 120 on this page, while the 901 belongs to the OfficeJet 4500 and J-series. The cartridges are not interchangeable.

• Is this an original HP set?

  No. It is a Clever Supplies compatible set built to the original HP specifications and covered by our lifetime warranty. It is not manufactured by HP.

• What if one cartridge in the set is faulty?

  Contact us with the colour and the problem — the lifetime warranty covers each cartridge in the set individually, so a single faulty cartridge is replaced on its own.

• Which cartridge in the set runs out first?

  It depends on what you print: text-heavy use drains the black first, photo and graphics work drains the colours. Each cartridge reports its own level, and the spares from this set store sealed until their slot asks for them.
