HP DesignJet 800ps error 86:01 severe error 0x8010001

Question

We have an HP DesignJet 800ps in which we have just changed the belt. After 2 successful (black only) printouts, and 1 unsuccessful colour printout (the blacks were all very grey and no color was printed) the front panel now displays error 86:01. If we hit "menu" we see  "Severe error 0x8010001." 
I have lubricated the slide bar. I have cleaned out all the dust from the suction holes. I have run all the tests I can (by holding down "up-arrow" + "enter" on bootup) and they all come out OK.
The one thing I haven't done, mostly because I'm not sure how, is to do step number 5 on the error boot, "Align print heads"

This is the only forum for the DesignJet 800ps printer there is! Suggesting a different forum is not what I would call "customer support" instead, I would call that a lazy response.
The link I gave above is for Designjet's and will be populated with users with experience that may be able to answer your question.  This forum is focused on consumer level products - Deskjet's, Photosmart printers and similar products tpically selling for $500 or less.
Although you may be a standard consumer the Designjet's are not typical consumer items.  You are free to ask here, but you should be aware that you are likely to get much better results posting in the HP Enterprise Designjet forum here.
