Printer error 57.40

This error comes up when turning on my 4600DN. Just confirming: 57.40 indicates a fan problem? My fan finally quit spinning. Is it Part # RH7-1490-000CN, and is it the only fan for the 4600DN? How hard is it to replace? Any tricks to the job? Thanks

Re: Printer error 57.40

There are two fans if I remember correctly. One is the cartridge fan and the other is the formatter fan and I think yours is the formatter fan. It is located at the top rear of the printer under the top cover but a lot has to come off to get to it. That said sometimes you can get them going again if you remove the fan and then peel back the label on the fan very slowly which should expose the shaft of the fan. Put a small drop of light machine oil on the shaft and then put the label back over it and spin it a couple of times. Clean the blade is very dirty, reassemble and keep your fingers crossed. I fix about 60% of the bad fans I encounter this way. Below is a link to a site where you can download the service manual as you will need it to get to the fan. Good Luck.

57.4 Formatter fan error (F1)
1 Reconnect the connector J1003
on the DC controller PCB.
2 Immediately after turning the
printer on, measure the voltage
between pins 1 and 3 on the
J1004 connector. If the voltage
changes from 0 V to 24 V, replace
the formatter fan.
3 Replace the DC controller PCB.
Calibrate the printer after
replacing the DC controller.
