HP Deskjet 2542 when I press the copy button the light goes always to the right as if want to start. it stay there for about 10 Second and then it give me a blank page. Printing thru the PC it's ok. I have try all the tips, reloading the set up, updated the firmware, re-setting by shutting the power off many time with no luck.
This looks like a hardware issue with the scanner mechanism. Let us try these steps:
Reset the printer
With the printer turned on, disconnect the power cord from the rear of the printer.
Wait at least 60 seconds.
Reconnect the power cord to the rear of the printer.
Turn ON the printer, if it does not automatically turn on.
Wait until the printer is idle and silent before you proceed.
HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Check the scanner bar functionality
Perform a visual test of the scanner mechanism to see if it is jammed.
Remove any original documents or photos from the scanner glass.
Lift the scanner lid slightly, and then press the Copy button or icon.
If the scanner light does not move or moves halfway or is not lit, the scanner mechanism is likely jammed/broken. In this case, please reach out to the HP Technical Support team in your region regarding the service options for your printer.
