NOTE Service Tests and Utilities Report the values to the nearest HP Response Center or HP Support Office to determine whether values are within the accepted range. When reporting the values, have the following information ready: n Model and Serial Number of the Printer. n All values reported in the test. n The Service Configuration Print ⇒ Page 1-37. To check if the values displayed after the test are within the limits, refer to the following table: Maximum PWM Average PWM Without Media Between 66 and 93 Between 67 and 85 With Media Between 65 and 100 Between 70 and 90 If values are not within the accepted ranges, power the Printer OFF and perform the following steps and repeat the test after each one: 1. Lift the Media Lever and insert thick media into the paper path to push out any media that may be stuck there. 2. Open the Window and check for any visible obstacles restricting the movement of the Drive Roller. If there is a wrinkled mass of media inside the paper path, lift the Pinch Wheels (using the Media Lever) and clear the obstruction. If you cannot reach the media, remove the Entry Roller ⇒ Page 8-106 to gain better access. 3. Remove the Paper-Axis Motor (⇒ Page 8-100) and check the Drive Roller movement is smooth and if it is not, remove the Center Platen (⇒ Page 8-112) to check for any obstructions. 4. Replace the Paper-Axis Motor ⇒ Page 8-100. HP DesignJet 5000 Series Printers Service Manual 4-13
