Re: officejet 4315 slow printing issues after print cartridge replacement

Yopu might try re-aligning the printer again

1. Load unused, plain, white letter, A4, or legal paper into the input tray.
   NOTE:If colored paper is loaded in the input tray when the print cartridges are aligned, the alignment will fail. Load unused, plain, white paper into the input tray, and then try the alignment again.
2. Press Setup .
3. Press 6 to select Tools .
4. Press 2 to select Align Print Cartridge .
   The unit prints a print cartridge alignment sheet.
5. Load the alignment sheet print-side down and top first in the center of the document feeder tray, and then press OK .

6. The unit aligns the print cartridges. Recycle or discard the print cartridge alignment sheet.
