Rooler kit error

"I know I'm a biot late to the party here but I just worked on an M3027 with that same error. It turned out to be the scanner head lock was in the locked state. Tried unlocking with the machine still on which didn't clear the error but after a power-cycle with the head unlocked the error was cleared. Nice simple and free solution!"

Measure the voltage between
connectors J103-4 and J103-6 on the
DC controller PCA right after the product
is turned on. If the voltage changes from
0V to approximately 24V, replace the
VOC fan. If replacing the fan did not work, then check the connectors on the DC controller, if they are seated then it is possible that the DC controller is bad.

Make sure that the machine is power off before the installation, and it should work ...

You must first clear the error by disconnecting the network cable and power off the machine allowing it to sit for a couple of minutes before powering on. Use that time to find the person who sent the job to the print queue and have them delete it.
Once the error is clear you need to upgrade the firmware on the printer. Upgrade cane be found here: http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=3687301&prodTypeId=18972&prodSeriesId=3644750&swLang=8&taskId=135&swEnvOID=54
