How to Troubleshoot an HP 1510 Printer

Check to make sure that the power cord is securely plugged into an active wall outlet if your printer is not turning on.
Make sure that the USB cable connecting your computer to your printer is securely connected if your printer powers on but will not perform a print job.
Remove a paper jam if the 'Check Paper' light on the front of the printer is blinking. To do this, first turn off the printer and unplug the power cord from the printer. Open the front cartridge door and locate the jammed paper. Gently pull the jammed paper toward you. Plug the printer back in and turn it back on.
Connect your printer to a different USB port on your computer if you are experiencing slow printing. The slowness could be due to a connection problem with your computer's USB port. After you've switched the port, try your print job again.
Make sure that a phone line is securely connected from a phone jack to your printer if you are having trouble sending or receiving faxes.
Clean the scanner surface if your scans are blurry or have vertical white or black lines. To do this, spray the a soft, lint-free cloth with a mild glass cleaner. Wipe the scanner glass with the cloth and then dry it with another clean lint-free cloth.
Hard reset the printer if you are having trouble solving your problem. Turn the printer off and remove the power cord from the wall outlet. Wait at least 15 seconds and plug the cord back in. Power the printer on and try your job again.
Restart your computer if you can't solve your printing or scanning job. Sometimes restarting the computer can solve an unseen problem.
