My printer has suddenly stopped printing the black text on pages but still prints the highlighting on the areas I have highlighted. I have only had the printer for 5 weeks and the cartridges are the ones which came with the printer. When I checked the ink levels all appeared to be OK. How can I resolve the problem.
Welcome to the HP Forums. I would be happy to help you with your HP DeskJet 3637 printer. I understand that your printer is not printing in black and you have already done some preliminary troubleshooting.
Don't worry though as I have a few steps to determine the issue and find a solution as well,
Check estimated ink levels again.
Align the ink cartridges.
Clean the ink cartridges.
Load U.S. Letter or A4 size, unused, plain paper into the input tray.
Press the Power button to turn on the printer, if it is not already on.
Open or search for the HP folder in your list of installed software programs, click the folder for your printer, and then click the name of your printer.
The HP Printer Assistant software opens.
On the HP Printer Assistant window, click Maintain Your Printer.
Click the Device Services tab, and then click Clean Ink Cartridges ().
Examine the Print Quality Diagnostic page.
