T790/T795/T1300/2300 Interconnect PCA Board Cable

08:04, 08:11 errors troubleshooting Watch this video: Warning . . . HP has written firmware which marries new boards to the printer. It cannot be reused. If you install a new board, the board is married to your printer. Used boards cannot be returned for a refund. I only sell factory sealed parts. --------------------------------------------------------- Here is a link I have for the firmware download: https://designjetpartsfast.com/collections/designjet-t-series/products/designjet-t-series-older-version-of-the-firmware Save the older firmware file to a USB stick and try to boot off of it. Afterwards, remove the USB stick. It may take 3-5 boots to load. --------------------------------------------------------------- Before ordering any parts, if the formatter LEDs indicate: LED1: FLASHING LED2: ON LED3: ON . . . then you must test the condition of the Engine to Interconnect cable first. --------------------------------------------------------------- Link to service manual pdf file: https://www.laserexpressinc.com/manuals/HP/hp-dsj-t790-t1300-z5400-t2300-service-manual.pdf Left Cover removal instructions begin on page 414. Right Cover removal instructions begin on page 475. --------------------------------------------------------------- Engine PCA Snoppy cable. 1. Remove the left cover. 2. Unplug the Snoppy Data cable on the Engine PCA. 3. Reboot the printer, and check printer behavior. Front panel cable and interconnect PCA. 1. Remove the right cover. 2. Locate the interconnect PCA (4x4 board, facing front). 3. Unplug the cable in the upper right corner (labeled printer data). 4. Reboot the printer, and check printer behavior. Does the printer boot up normally? If yes, cable is shorting out the printer. Either use the printer as is, or else, replace the cable. If no, is the LED light on the interconnect PCA? If no, the board may be dead; I would try replacing the PCA. If the LED is 'on' PCA board is good. --------------------------------------------------------------------------------- The formatter board has either a network cable or USB cable plugged into it. Next to the connector there are 3 LEDS on the formatter board. They are labeled I, II, III. They will either be solid or flashing. You need to determine what the sequence of the three LEDS are in order to decode the error. Here are the most common errors. This LED sequence points to a faulty Hard Disk: LED1: FLASHING LED2: OFF LED3: OFF Faulty Hard Disk: LED1: ON LED2: FLASHING LED3: OFF Replace the Formatter: LED1: ON LED2: OFF LED3: OFF Replace Formatter and Main PCA board: LED1: ON LED2: ON LED3: OFF Replace Main PCA board: LED1: ON LED2: ON LED3: FLASHING All parts are available elsewhere on the website.
