NOTE Troubleshooting 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. 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 ⇒ Page 8-79.
