Not printing the top half of letters on HP OfficeJet 4680 printer
Well, this can be an almost entry print cartridge. Or a clogged print cartridge. Or a broken wire that connects to the print head so that it does not work the top half jets. Or a bit of dirt or stuff on the pad that connects the cartridge to the print head.
1. Remove the cartridge, and blow the area out with canned air. Shake the cartridge, both to redistribute ink and to verify the presence of ink.
2. Examine the ribbon cable that connects the cartridge to verify that it is intact.
3. If and only if you can't find a problem in the above, (or if they are empty) replace the cartridges.
