Hi,
may somebody can help me. hopefully!
I have a HP Color LaserJet 4500 at home. Now I have a problem with the upper front drawer fan. It does not work anymore and I get an Error "57.3 FAN ERROR".
Now I did already change it against an other 40x40x10mm fan, but the printer do not like a fan with a "Tacho-Signal".
Does somebody have a fan somewhere? May form a not working printer. It's form NMB 1604kl-04W-B59 (L01). Look the attachment for the details.
I found different websites, but they sell only 400 or more items. From HP, I got the proposal for a new upper front drawer. But this part is about 200 USD.. and this is too much.
Thanks crazymelki
Description form the service manual about the error:
The intake fan is located in the front, center of the drum drawer (refer to Figure 7-32). (The drum drawer is referred to as the upper front drawer for end users.) Fan rotation stops when the drawer is opened. A fan error message appears when fan motion is NOT detected by the DC controller’s
