    WHat model is this? there should be two more Characters such as H4-00

    If you have an LED displaying H4 hold down the green button for a sec and if 00 flashes behind the H4 then you have a fuser unit problem..

    Error code 5010

    Yes, same thing happens to me...Error code 5010...and flashing green and orange...alternating lights.

    I was trying to photocopy (in basic black, not colour). I had a few pages to copy. I got this 5010 Error code after EACH copy!

    I had to turn off the printer after each copy and then turn it back on for the next copy. That's not the worse of it.....once I turned the printer back on and hit copy again...the printer took a VERY long time to scan the item for the next copy. It took me a good 40 minutes to copy 15 pages.
    Sooooo irritating!!!!!

    Anyone know what to do?

    I've also had the paper jam on me tons of times. I am really disappointed with this product. I would not recommend this printer to anyone!
