Troubleshooting Performing the Necessary Service Calibrations Is the printer calibrated correctly after replacing a component? For information on the Service Calibrations and how to use them, see Service Calibration Guide to Removal and Installation , Page 6-8 and Chapter 4, Service Calibrations . Remember that certain Calibrations are required even if an Assembly has been disassembled to gain access to another Assembly or Component. The Printer does not Power ON 1 Check that the power cord is connected correctly to the Printer and to the Power Socket. 2 Check that the Power Switch on the BACK of the Printer is in the ON position.
3 Check to see the LED on the Front Panel Power Switch are On. 4 Check that the Front-Panel Cable is correctly connected to the Electronics Module. Also make sure that the Front-Panel cable is not damaged. 5 Replace the Power Supply Unit ⇒ Page 6-164 . The Printer Continuously Rejects Printheads 1 Clean the flex contacts on the Printhead and in the Carriage Assembly using the Carriage Interconnect Wiper (Refer to Page 1-72 ) and try again. 2 If ALL the Printheads are rejected (the status message on the Front Panel does NOT show "OK" for ALL the Printheads) then perform the Electronic Module Test ⇒ Page 3-22 .
Cover Sensors are not Working 2 Check if the cable for the faulty sensor is not damaged and is connected correctly. 1 Perform the Sensors Test ⇒ Page 3-33 . 3 Replace the faulty Sensor. The Line Sensor has Problems Detecting Media 1 Check the type of media that is being used since the Line sensor may have problems detecting transparent media or some types of Non-HP media. Try loading white HP media in to the Printer and check if the Line sensor detects it. 2 Sometimes the line sensor has problems detecting media when sheet media is loaded without a skew check. If the media type allows, always use the automatic skew check feature.
If the media type does not allow automatic skew check, manually check that the media is correctly positioned. 1-6 Designjet Z Series — Service Manual
