Designjet Z3200PS Q6721B
Microsoft Windows 7 (64-bit)

I have been fixing this mchine for over 2 months & never be able to finish since, even  I already updated to the latest firmware I download from HP website, I still get 79:04  after printer 100% initialized & never be able to load a roll of paper to perform printhead alignment.

 

Belt, service station, carriage box, printheads, inks ,encorder strip, all perfectly.

 

But today I updated the latest firmware again, after PC uploaded all firmware 100% to the machine, then

the machine reboot by itself. I was standing beside & saw after it reboot & 1% apeared, then when it reached about

60% & hour glass appeared & quickly gone, then beep & machine reboot itself.I tried again 2nd time & same.

 

My other Z3200 44" always got to 100% & why this one only got to 60% & reboot by itself ?

 

I suspect the 79:04 error might related with unfinish firmware update ?

 

I am looking for a link to download the older version to try ....

 

thanks for your kind helps.

Finally I found what was wrong with this printer's 79:04 error, when tried to load paper.

 

Today I tried to remove the carriage box & the center of the pulley broke apart, that was the reaon when

carriage box moved & the belt moved unevenly & caused the error right away.

 

Glad the another problem solved & printer fixed.
