NOTE NOTE Troubleshooting 3. The dry time at the end of the print is longer. Normally the Printer uses the temperature and the humidity reading from the ISS PCA to calculate the dry time, which is required for the print to dry before being cut. The specification of these readings is +/- 15%, so a variation in the calculated dry time of up to 30% is within specification. n To check the correct functioning of the sensor, print the "Service Configuration Print" and check that both the temperature and humidity readings are correct (i.e. within the specification). If not, replace the ISS PCA ⇒ Page 8-86. n As an alternative solution, turn OFF the dry time, and then all the Printers should finish the print at the same time. n Another alternative is to set the dry time manually on all the Printers. This dry time will be applied to all the prints. Language Selection is blocked in a brand new printer Normally the user has about 2 minutes (initialization time) to select the language in the Front Panel. If the language is not selected within this time period, the Front Panel is locked. n To recover from this problem, just re-boot the Printer and select the language within the specified time (2 minutes). Firmware Upgrade Does Not Work Through the Parallel Port With firmware revisions A.01.10, 11 & 12, the Printer will remain at 90% when doing a Firmware upgrade via the parallel port. n For the customer, recommend using the network to print and to perform the Firmware upgrade. n For Service Engineers: - Keep the "Top Arrow" key on the Front panel pressed down when turning the Printer ON, and release it once the "Boot Menu" appears. - Select "Upgrade Firmware" in the Boot Menu. - Send the firmware through the parallel port. This problem is solved in any A.02.xx firmware release. HP DesignJet 5000 Series Printers Service Manual 1-23
