HP Print Head 6700 - HP Officejet 6310 All-In-One InkJet Printer

Hello, Lisa -

You can choose to print in black only. However, the black print will use not only the ink from the black ink cartridge but it will also draw from the 3 other color ink cartridges.

Bottom line: You will need sufficient ink in all ink cartridges even to print in black only.

Please read your HP 6700 user's manual, starting on page 74 of the manual.

In case you do not have the user's manual for your printer, this is the link so you can download and save the PDF (Adobe Acrobat Reader software, free) version of the manual:

Best wishes.

You should first try the cleaning procedure that is available through your printer's control panel - .HP Officejet 6600 6700 Printers Fixing Poor Print Quality Problems If that does not work here is a video on removing the HP print head.

The printhead is a non-replaceable part. There is a printhead cleaning procedure available through the device's menus. You might want to try performing the procedure numerous times.

Please clean the contacts on the back of the cartridge with soft tissue and some ethanol. Also check if contacts are not damaged.

I have used HP printers for years & never ever heard of this kind of thing. Go to HP.com & go to printer support & look it up or contact them.

When you click on the printer symbol to print there is an option to preview print.......this shows you exactly what will be printed without printing.

Pick up a can of electrical contact cleaner in an aerosol can at the auto parts store.Pull out the cartridges, and carefully hit each nozzle in the head with a short blast (use snorkel on the spray can). No reset, no nothing, just turn it back on and print.
