Printhead cleaning, just by buttons on the printer?

[P_A_Gulley]

The thing isn't copying well, there's bits missing, and parts are streaky. The cartridge indicators don't read as being low. The printer is not connected to a computer at the moment. It is being used to copy things.

I'd like to trigger a printhead cleaning cycle, without hauling the printer to where there's a computer, or taking a computer to where the printer is. However, I cannot figure out how to do this. Presumably there's some way that involves holding down one or more buttons while powering it up, as it is with some other printers, such as a Lexmark I used to use.

What is the method for triggering a printhead cleaning, just by using the buttons on the printer itself?

Sorry have to use a computer.  From the User Guide I downloaded and read...

Clean the print cartridges automatically, if the diagnostic page shows steaks or missing portions of the color
and black boxes.
To clean the cartridges automatically
a. Load letter or A4 unused plain white paper into the input tray.
b. In the Printer Software, click Print & Scan and then click Maintain Your Printer to access the HP
Deskjet 2510 series Toolbox.
c. Click the Device Services tab.
d. Click Clean Ink Cartridges. Follow the onscreen instructions.
