I want to test printer with no conection to the PC only test page. What buttons Can I press for to print test page directly of printer?

Let's start by trying this:
Unplug the printer power cord from the printer and the wall.
Turn off the PC.
Disconnect the USB cable from both ends.
Plug the printer back in and turn it on.
Now, can you print a self-test page from the printer?
Make sure there is unused, plain white paper loaded in the input tray.
On the product control panel, press and hold the Power button and the Cancel (X) button at the same time.
Release both buttons. The diagnostic page prints.
If that does not work, are there any blinking lights on the printer? This document might explain them: Blinking lights.
If the self-test page does print normally, reconnect the USB cable, turn the PC back on and try to print a Windows test page:
Click the Windows icon and then click Control Panel . The Control Panel opens in a new window.
Click Hardware and Sounds .
Click Printers . The Printers folder opens.
Right-click the printer icon in the Printers folder.
Click Properties . The printer Properties window opens.
In the General tab, click Print Test Page . The Windows Printer Test Page prints.
If you have problems printing from Windows, you can try some of the troubleshooting steps in this document:

Finally, you may have to uninstall and reinstall the print driver.

First check the printer itself is working OK by printing a test page.
Most printers have a power-on self test (eg press feed button while pressing power on - please consult your manual). If the test print is OK, then it's the PC or connecting cable. You could try any other PC or laptop (you would have to instal your printer software first) but just try re-installing your printer software first on YOUR computer. If that doesn't work try any other PC or Laptop available as directed above.
USE A FILE THAT YOU HAVE PRINTED OK BEFORE IF POSS.
If none of the works then the cable is suspect.

First, print an Engine Test Page.

To print an Engine Test Page, open and close the cartridge door five times while the printer is in ready mode. The printer should print one page with multiple horizontal lines.

If the engine test page printed, is a comunication problem (PC configuration,PC/Printer conection/Driver bad installed)

Hi there!
If the test page from pc or the machine test page doesnt show black, what you can do is to clean the printhead. To do that press the Ink Management button on the control panel and select cleaning press ok then press the up or down arrow key to select Black press ok and press Black Start. After the cleaning process print another test page. Compare the 1st and 2nd test page if it's improving, you may need to do this 3-5 times.
Hope this helps Please rate if it worked Thanks!
