Four-pack cyan refill for HP 503A cartridges

This kit supplies four cyan toner refills with replacement chips for HP 503A cartridges used in Color LaserJet 3505, CP3505, 3600 and 3800 series printers. It targets offices and home users who want to reuse their original shells and lower per-page cost. Each refill is rated at five percent coverage. The product is new and ships as a complete four-pack.

Consistent output across multiple refill cycles

The toner formulation is designed to maintain print density and colour accuracy through repeated refills of the same cartridge shell, up to three cycles per cartridge. Integrated chips reset the printer’s page counter so the device recognises a full supply. Performance stays stable during long print runs without the fading that can appear with single-use compatibles. No drum or developer components are included.

Simple pour-and-reseal process with chip swap

Installation requires opening the cartridge’s fill plug, pouring the toner, resealing the plug and snapping the supplied chip onto the cartridge’s circuit board. Common issues are toner spillage if the plug is not fully seated and chip recognition errors if the contact pads are dirty. Clean the chip contacts with a lint-free cloth before fitting. No tools beyond the included funnel are needed.

Questions about this item

How much heat or noise does the cyan toner refill add when the HP Color LaserJet CP3505 runs all day?

The refill kit is passive toner powder and chips; it adds no heat or noise beyond the printer’s normal operation.

Which empty HP cartridges and chips must I already own to use this 4-pack cyan refill for the 503A series?

You need four empty HP 503A cyan cartridges (Q6470A, Q7581A, Q7582A or Q7583A) that accept replacement chips.

Will the refilled cyan cartridges work reliably in an older HP Color LaserJet 3600dn that I keep alongside a newer CP3505X?

Yes, the refill is listed as compatible with both the 3600 series and the CP3505 series printers.
