Common user issues with the K550dtn—and how the right supplies help If your HP OfficeJet Pro K550dtn prints with missing lines, uneven color, or faded areas, the cause is often an empty cartridge, a cartridge that has been stored too long, or a printhead that needs attention.

In this category we also offer genuine printhead options: - Original OEM Printhead HP 88 BK/Y (C9381A)
- Original OEM Printhead HP 88 M/C (C9382A)
If black or yellow looks inconsistent, the BK/Y printhead is the relevant part; if magenta or cyan is affected, the M/C printhead is the one to check.
