M651 color laserjet. Bought this printer used. Before shipping the supplies status page showed 90% fuser and transfer kit. So I figured I might be into it for some toner but no major repairs or parts.

Experienced technical support provide their insights in answering this question :
I once bought a factory refurbished printer. When I got it, it was a mess. I counted 12 individual problems I had to fix. Not much advice one can give considering there is no way to tell what damage occurred from the packing and shipping fiasco. The cartridges, waste box should have been removed prior to packing it. I suggest you try for a refund.

When 51.00. xx Error To continue turn off then on is displayed on the control panel, it indicates that there is a laser/scanner assembly issue. The XX is a two digit code that provides information on the specific issue causing the error. Turn the printer off, and then back on to clear the error.
The default on Enterprise products is NO password. If it is asking for a password someone has assigned one already.
Enterprise-level devices are designed to handle higher print volumes and end-users. In contrast, Pro-level devices are ideal for no more than one to two end-users. For some situations, we do recommend Pro series printers.
Your printer should have been packaged with a USB cable regardless of whether it is a wireless or wired printer. Plug the cable into your printer and your computer`s USB port. The direct linking should trigger your computer to recognize the printer and start up the software needed to complete the installation.

My 2550n Color LaserJet does not want to print in color
ANSWER : That model had issues with the carousel solenoid sticking. That might explain why it works after you let it sit for 10 minutes. The solenoid gets hotter with use which causes the deteriorated foam on it to become sticky and hold down the release plate instead of letting it go. This allows the carousel to spin when it is supposed to stop for each color. The solenoid is located on the right side of the printer. If you open the lid, it is just behind the opening at the top right. You need to remove the top of the printer and scrape off the goo on top of the solenoid body. I put a piece of thin sticky backed felt to replace it. Other people use electrical tape.

ANSWER : What about the engine test? To do that, drop down the front tray. Feel around on the left side at the top and you’ll feel a little plastic dongle. If you lift up on that it will initiate an engine test page. That will be a page containing lines of each color.
