Warning: Improper RIP board replacement can result in incorrect printer function and significant additional service time due to loss of data. Warning: Also if both the RIP and engine boards are being replaced, DO NOT replace both at once. Replace one board at a time, following appropriate procedures for each. 1. 2. 3. 4. 5. 6. Remove the outer EMC shield. See "Outer EMC shield removal" on page 4-47. Remove the rear cover. See "Rear cover removal" on page 4-8. Remove the USB connector screw type "232" (A). Remove the RIP board screw type "232" (B). Remove the parallel connector (C). Disconnect all cables from the RIP board and remove the board. Installation notes Perform the following steps to install the replacement RIP board: 1. 2. 3. 4. 5. 6. Turn off the printer. Install the replacement RIP board. Turn on the printer. When the operator panel prompts NV Rip to Eng, choose STOP. This prevents transfer of data from the RIP board to the engine board. When the operator panel prompts NV Eng to Rip, choose GO. This transfers data from the engine board to the RIP board. The printer restarts at this point. At the READY prompt, print a Menu page and look for the correct printer name and equivalent/updated RIP code level. The Menu page prints with acceptable print quality indicating calibration data has been properly preserved. 4-70 Service Manual
