HP DesignJet 5000 Series Printers Service Manual
Electronics Problems
1. The Printer hangs with the front panel completely blank and the
three Image Quality LED’s lit.
The firmware has a bug that creates this situation whenever the
Printer is receiving data from an external RIP.
n The customer should print using the HP Driver to check that the
Printer is printing without any problems.
n The only solution to this problem will be to upgrade to the
firmware for the UV inks (A.02.XX) when it is available.
NOTE This problem is solved in any A.02.xx firmware release.
2. The Printer hangs at "Initializing Please Wait".
The Printer hangs showing the following front panel message for
more than 5 minutes: "Initializing Please Wait, Code Rev. xxxx,
Boot ROM. xxx, etc".
The cause for this failure could be either a print sent through the
Parallel or LAN port during initialization, or a defective I/O card.
n Power OFF the Printer, disconnect the Parallel and/or the
Network cable and power ON the Printer again to see if the
Printer hangs again.
n If the Printer did not hang again, then the problem was due to the
Printer receiving data through the ports while the Printer was
initializing. Before connecting the cables again, make sure that
all the pending print jobs are purged.
n If the Printer did hang again, then power OFF the Printer, remove
the I/O card and power ON the Printer again to see if the Printer
still hangs.
– If the Printer did not hang again, install the I/O card in the
second slot and check whether it works there. If the I/O card
causes the Printer to hang again, replace the I/O card. If the
Printer continues to hang, even with a new I/O card, then
replace the Main PCA
