Error 61 is a process motor error.
sometimes it can be cleared by turning the power off (hard) waiting a minute and turning it back on again.
Otherwise I'm afraid its a Xerox customer support job (the printer division is now part of Xerox Inc).

I had that problem and found it to be simply that the plastic arm of the sensor which watches the output tray on top for an over-full condition got stuck in the UP position. The unit never got to the initialization stage upon powerup because it thought the output tray was full. Just fiddle with that little arm to be sure the pivots are engaged in the holes in its "ears" and that it can move up and down freely.

Replace the Phaser Chip into a QMS 330 Chip ("OPC Drum chip")
It's the chip that tells the printer also that it's a QMS item, regardless if it's originally a Phaser OPC.

It appears that the printer might not be recognizing the printer cartridge. Please turn off the printer and unplug all cables. Remove all the cartridges and reseat them, make sure all are fixed properly. Keep on holding the power button to 15 sec (make sure power cord and any other cord attached to the computer is disconnected). Once finished, pluggin the power cable and restart the printer, that should take care of the business.

Thanks and regards,

I have to ask this question of you, just to make sure this is not an issue. Are you using a factory new ink or toner cartridge?
Please consider the following:
If you are using a refilled or third party cartridges that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks or toner causing problems with print quality or damaging the physical printhead or photo conductors.
If you are using factory new ink or toner cartridges, then please call the manufacturer’s Technical Support for assistance with the warranty on the cartridges

This problem occurs do to a defect in the fuser drawer. In the fuser drawer, there are two black plastic parts that can go up or down. Their function is to push the belt cleaner on and off the accumulator belt after every pass. A defect in this system causes these parts to stay up, pushing the belt cleaner on to the belt every step except the last one, causing only the black toner to remain on the belt.
It's hard to track what the exact cause is but I would recommend checking gearing and gear teeth in your fuser drawer.

Best thing to do is just brush most of it out with an unused paintbrush. You can simply vacuum the rest out with the hose attachment. Hope this helps :)

We had similar problem.  There is a tiny little black plastic arm where the paper comes out of the top.  If you're facing the screen, it will be towards the bottom left.  I couldn't find it on the parts list, but it's similar to part 118-9754-00 (Multi-purpose tray paper sensor actuator) from the parts list website:http://www.office.xerox.com/userdoc/P780/partslist/index.html.  .  We had broken that part when we moved and thought little of it until we got the hanging initialization.  Check to see that it moves freely and is not broken.  It was a pricey part for what it was, so you might look at a salvaged part.  Hope that's the problem as it is an easy repair!  If that doesn't do it, we had a door that didn't make good contact that also caused similar problem.  Good luck!
