Frequently Asked Questions

Which cartridge in this set goes into which slot of the 5500dn?

The set follows the standard 645A layout: C9730A is the black, C9731A the cyan, C9732A the yellow and C9733A the magenta. Each cartridge is keyed and labeled for its own slot, so the four — $610.91 for the complete set — can only seat in the positions they were made for.

Does two-sided printing ask anything different of these cartridges?

No. The duplex unit flips the sheet; the same four cartridges image both sides of it. Two-sided color reports and booklets draw on the C9730A, C9731A, C9732A and C9733A exactly as single-sided work does — the yield figures simply get spent across both faces of the paper.

How far does a full set stretch on a shared network machine?

The black is rated at 13,000 pages and each color at 12,000 pages under standard coverage. On a networked 5500dn serving a whole team, treat those as planning figures: a department printing color reports daily will move through the colors faster than one printing mostly black text.

When is the right moment to swap the whole set on a team printer?

Plan it around the machine's low-toner warnings rather than waiting for a mid-job failure. A scheduled change during a quiet stretch lets the 5500dn calibrate once on four fresh cartridges, and nobody's print run is interrupted by an empty slot.

Can a single color be replaced on its own later?

Yes — each 645A cartridge also exists as an individual purchase, so if the yellow gives out months before the rest, that slot alone can be refreshed. The full set is the economical reset point when several cartridges are nearing empty together.

Who helps if a cartridge misbehaves after the change?

Start with our support team — they answer Monday–Friday, 9 AM–5 PM CST and will talk you through isolating the problem unit. Coverage behind the set runs to a 1-year warranty and 1-year free returns, and the shipping & returns page walks through how a return is arranged.

About This 645A Set for the Color LaserJet 5500dn

A duplexing, networked machine like the Color LaserJet 5500dn usually belongs to a whole team, and its toner changes land best as planned maintenance. This set replaces every cartridge in one visit, after which the printer returns to two-sided color work with all four channels at full strength.
