HP LASER JET 4si

This printer keeps saying 57.4 service. Does anyone know what that means and what we need to do to it?
The HP4si Operators Guide says on page 6-30 -
"Internal Fan Motor C failed.
Recommended Action - Turn OFF the printer, then
turn the printer back ON. If the problem persists
, contact your dealer or your HP Service Representative"

Sending someone to an authorized hp repair center is not condoned on this site. We exist because of the extremely poor work, slow repairs and high prices these centers offer. Don't ever make the mistake that just because they are hp authorized that they are competent. All you need to do to become hp authorized on equipment is pay the money and go to a class. I get botched repair work from this hp authorized center down the street from me all the time. Our shop does all the repair work for another hp authorized shop that doesn't have a tech anymore. That's right, if the tech leaves, they are still authorized.

Mine says it's either a loose J010 connector on the DC controller or a bad main motor PCA or a bad main motor.
