hp lj 4345mfp no tray lift

[ringling1]

have a 4345 mfp that will not lift any trays(it is outfitted with 3 optional trays) originally could only get it to respond by unplugging the hard drive. replaced the hd which seemed to correct the problem, a week later we are back to no tray lift. has anyone seen this before? could firmware be an issue? if so, how do you update through usb? thanx

2. How to send the firmware upgrade using a USB connection:

2. Type: copy /b filename \\computer name\share name

As a must for all HPs machines. Whenever you have issues, and the machine firmware can be updated, do it first before troubleshooting futher. HPs are know for their bugs and firmware are freely avaliable at their website. First print menu map and configuration page for your reference, do this for any machines you are working on that can print the configuration and status pages.
First do Hd initilize and then firmware update. If problem still persist, do cold reset. Get a service manual and read what settings will be lost ect.
ALSO, why do firmware by UBS. This machine has a built in nic port and you should use the FTP method for upgrading the firmawre, it is easy, quick and reliable.
Use a crossover cable and your laptop. When you run the downloaded exe. firmware file and run the extraction process, it creates a readme.doc file that has all the methods for f/w update and other usefull information. USB method is tedious and is troublesome, but it works.
