Do you have a trouble shooting manual that you could e mail me so I could print it and have it at the job site.

You checked the electrical outlet with a lamp? OK? check the electrical cord snug plugged in? both printer and wall. Third pull out label roll power on any indicators come on? clear all print jobs to the printer. check the web site of the printer for any update problems.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

turn on/off, unplug, plug in, should reset configs.

go to applications folder for your computer, dbl click printer icon for make of printer. check settings. print 'test document and clean cartridge heads', this should ensure proper printing formats.

lastly, go to web site of printer model and check site for trouble shooting if this does not work above. HP has an awesome web site for trouble shooting if all else fails
hope this helps and good luck

try hoshi web sight. Has all manuals and trouble shooting guides. Good site to visit. You can print out your manual or save to your computor or disc

Here is a link to the LJ1012. There are links for manuals, drivers, support forums, etc.

As to your question, here are the brief descriptions of the 2 lights and 2 buttons...from top to bottom:

1 Attention light: Indicates printer media input tray is empty, print cartridge door is open, print
cartridge is missing, or other errors.
2 Ready light: Indicates that the printer is ready to print.
3 Go button and light: To print a demo page or to continue printing while in manual feed mode,
press and release the Go button. To print a configuration page, press and hold the Go button
for 5 seconds.
4 Cancel Job button: When the printer is processing data, press the Cancel Job button to
cancel the print job.

Also, see if powering down the printer and unplugging it from the wall outlet for several minutes clears the repeating of the print job.
