HP Color LaserJet CP3505DN Toner Cartridges

Color LaserJet CP3505DN

Duplexing and networking made the Color LaserJet CP3505DN the shared color printer in a great many offices, and feeding it is a four-cartridge routine. Black comes from the 501A cartridge, HP part Q6470A, while the color side runs on the 503A line: cyan Q7581A, yellow Q7582A and magenta Q7583A. Each slot holds its own cartridge, so the machine tracks and empties the four supplies independently.

On a shared printer the workload is never one person's: two-sided reports, color handouts for meetings and the odd full-color cover page all land on the same four cartridges. Because the CP3505DN prints on both sides by default in many offices, paper costs fall while toner use stays steady — black does the heavy lifting on text, and the three colors are spent mainly where a page actually carries color. That mix is why black usually runs out well ahead of the colors here.

Which cartridge should you buy?

For everyday office volume, the standard Q6470A black covers text-heavy printing without overspending. Departments that run the machine hard should step up to the 501X extended-yield black (Q6470X), which stretches the gap between swaps on the same printer. Colors are best bought one at a time — order the Q7581A, Q7582A or Q7583A that the panel names, and leave the others in place. When several colors are low together, or the machine is new to you, a full set such as the 501A–503A four-color set resets everything at once; the two-black set suits offices whose color use is light but steady. Every compatible cartridge on this page carries a 1-year warranty and 1-year returns.

Chip, toner and everyday use

Slide each cartridge in until it seats with a click; the chip on the shell is what the printer reads to report levels, and a cartridge that is not fully seated is the usual cause of a 'not recognized' message — pull it out and refit it before suspecting the cartridge. Yield figures are estimates built on roughly 5% page coverage, so a month of dense color pages will empty a color far sooner than the rating suggests. A gentle rock of a low cartridge redistributes the toner inside and buys a little more life. Keep spares sealed, upright and out of direct sunlight.

Frequently Asked Questions

Which toner cartridges does the Color LaserJet CP3505DN use?

Four separate cartridges: black Q6470A from the 501A line, plus cyan Q7581A, yellow Q7582A and magenta Q7583A from the 503A line. An extended-yield black, the Q6470X, fits the same black slot when you want fewer changes.

Does the CP3505DN use the same toner as the base CP3505?

Yes — the whole CP3505 range shares the 501A black and 503A color cartridges, so the Color LaserJet CP3505 and its networked CP3505N sibling take exactly what is listed on this page. The DN letters change the printer, not the toner.

Only one color is showing low. Do I replace all three?

No. The cyan, yellow and magenta cartridges are independent, and the printer reports each one on its own. Replace the single color the panel flags and keep printing with the other two.

Is there a separate drum unit to buy for this model?

Nothing on this shelf is a drum or maintenance item — the range stocked for the CP3505DN is the four cartridges themselves. Order by the cartridge code on the box you are replacing and you have everything the swap needs.
