do the self check it should have.


when power light goes off press and hold both the MENU AND INPUT (also called DEVICE) together for 5 seconds and release both.

The power light should blink a two digit error code---like 2 blinks, a pause and 2 blinks.

Let me know what error code you find and I will tell you what it means.

If you do not get an immediate answer from me it is because it seems the Email system here is down and not working correctly right now.

I went to the HP web site. If the three lights are blinking in turn, the printer is still trying to initialize or clear a previous job. If all of the lights are on but not blinking, you should turn off the printer and then turn it back on. If that doesn't help, turn it off and unplug it for 5 minutes before plugging it back in and turning it on. If the printer still gives an error, contact HP. If the three lights are blinking simultaneously, you have a memory error. However, the DIMMs are not replaceable on the HP 1150, if I understand correctly.

I hope this helps. (Please note: on many USB printers, it is useful to unplug the USB cable from both the printer and the computer, as well as unplugging the power cable when attempting to clear an error.)
