Z5400

I've been on the phone with HP Support, one of my customers has the issue described in the title of the post.

 

Support says this is a known issue and with Firmware version: CH_08_02_00.1, (and also existed with version 6 of the FW).

 

Firmware version CH_08_02_00.1 is currently available on the HP Support Page for the Z5400 so it must not affect all machines.

 

Support also says there will be a Firmware version released that fixes the issue, but there is not a release date yet.

 

You need a TPW File, from HP Support, Version 7 of the Firmware also from  HP Support, and you must disable Automatic Updates.

 

The fix is for HP Support to send a TPW file that will enable a Firmware downgrade, that file is put on a USB Drive with no other files and when the machines asks if you want to print it answer yes.

 

Be sure to disable Automatic Updates either before you do the Downgrade, or disconnect the network cable if you plan on disabling this afterwards.

 

Then power off the machine, plug in a USB Drive with the Firmware Downgrade file, (this should also be the only file on the drive).

 

If the machine still rejects some cartridges after the downgrade they will have to be replaced, HP should supply the replacements since the Firmware caused the issue.

 

@Mikeg81  do you have any insight on this?

Yes, I have checked the date and time and they are correct.

 

The reason for my post is that I could not find online documentation of this issue so I put up this post for others who had the same problem.

 

HP Tech Support L1 informed me that this was a known issue, and they had to contact L3, (level 3), support to get the file to enable the Firmware downgrade on the machine.

Hi, 

have you checked printer date and time?

After the firmware downgrade the printer still reported installation dates on four of the cartridges as being in 1969.

 

HP tech support had four replacement ink cartridges shipped and those were installed on Friday afternoon which resolved the date issue.

 

The machine is now up and running but unfortunately has some print quality issues which are likely due to not printing for a while and I think their printheads are probably all out of warranty.
