How can I print it doesn't print a test page

First step is to see will if it print a test page.
Go to Start, settings, printers. Right click on the printer, properties, print test page.If that doesn't work there should be a head cleaning option in properties that will make it clean the print heads.
Try the self-test? I'm not sure on the 5550 printer, but do this:With the printer ON,
1. Press and hold the power button
2. While holding the power button, press the resume button 4 times
3. Release the power button

See the marked micro switches, one of this might be short, replace the micro switch..

YOU NEED TO GO TO PRINTERS...AND CHANGE HOW PAGES YOU WANT TO PRINT...AND TAKE THE PAPER OUT OF PRINTER, SO IT DOESN'T USE UP ALL YOUR INK!

HOPE THIS HELPS!

See printer properties and set everything to default. cli-8y

Go to Control Panel/Printers. Right click on your printer's name, and hit Print Test Page. If printer prints a page out, then the problem is likely with the software you're using to print - make sure you have selected the right printer in the dropdown. If the printer's name doesn't show in the Printers folder of Control Panel, the driver for it has not been installed. Do so and try again.

It's likely dried out. Print a few test/calibration pages, or try to print a few pages of heavy ink-usage. If that doesn't open the flow, you'll just need to replace it.

test page printing but doc files not printing....
