Solve paper-handling problems Jams Common causes of jams The product is jammed. Cause Solution The source document does not meet specifications. Make sure that the document to be scanned meets the ADF and media specifications. See Paper handling on page 10 and Media specifications on page 10. A component is installed incorrectly. Verify that the imprinter cartridge, the ADF pickup roller, and the ADF separation pad are correctly installed.
Solve common ADF jams You can use this procedure when a jam occurs during a multiple-page ADF scan job or when a jam occurs during a single-page ADF scan job. 1. At the scan destination, examine the scan output to determine which page was the last to be completely scanned. 2. Reload the unscanned pages in the ADF input tray. If any pages are damaged, do one of the following: 3. ● Photocopy the damaged page, and then add the photocopy to the input stack.
Clear jams from the ADF 1. Remove any loose pages from the ADF input tray. 2. Lift the latch on top of the ADF to open the top and side ADF access doors (jam door 1 and jam door 2). Figure 6-20 Clear jams from the ADF (1 of 5) 3. Remove any jammed pages from the ADF input tray.
4. Remove any jammed pages from inside the ADF. Figure 6-22 Clear jams from the ADF (3 of 5) 5. Remove any jammed pages from the ADF output tray. Be careful not to dislodge or damage the imprinter cartridge or carriage.
6. If the jammed page still cannot be removed, follow these steps: a. Open the ADF. b. Push the green tab toward the ADF to open ADF jam door 3. If the door does not open automatically, gently pry it open. c. Gently pull the page out of the ADF. Figure 6-24 Clear jams from the ADF (5 of 5) 7. ENWW Close jam door 1 and jam door 2), and then close the ADF. If the jam occurred during a multiplepage ADF scan job, see Solve common ADF jams on page 268 for information about solving ADF jams.
The bottom of the scanned image is cut off By default, the scanner can scan paper that is up to 420 mm (16.5 in) long. If the document is longer, the end of the document is not included in the scanned image. For more information about paper handling specifications, see Paper handling on page 10 and Media specifications on page 10. Verify that you have specified an appropriate page size in the scanning software.
ADF does not feed paper ENWW ● The ADF access doors (jam door 1 and jam door 2) might not be securely latched. Open the ADF access doors, and then close the doors by pressing firmly. ● A problem with the ADF hardware might exist. Try the following: a. Disconnect the USB cable and the power cable from the scanner. Check that the power cable is still connected to the power source. b. Make sure that the ADF has at least one piece of paper in the input tray. c.
Solve image-quality problems Image defects These examples identify the most common image-quality problems. If you still have problems after trying the suggested solutions, contact HP customer support. Table 6-22 Image defect examples Problem Image example Scanned image is all black or all white. Scanned image is skewed. Scanned image is cut off. Solution ● When scanning with the ADF, check the paper orientation.
Table 6-22 Image defect examples (continued) Problem Image example Solution Scanner scans only one side of a double-sided page. ● For single-pass duplex scanning, scan pages through the ADF. ● Select the Duplex setting in the scanning or copy software. Scanned image is fuzzy. For images scanned by using the ADF, check the following: 1. Verify that the document original is not fuzzy. 2.
Table 6-22 Image defect examples (continued) Problem Image example Vertical white stripes appear on the printed page. Aa Bb C c Aa Bb C c Aa Bb C c Aa Bb C c Aa Bb C c Scanned image has poor contrast. Solution ● The destination printer might be out of toner or ink. Scan a different original to the same printer to see if the issue lies with the printer. ● If the second original has the same problem, clean the ADF or the scanner glass.
Filter out color from a document (color dropout) You can filter out a dark background from the image content, for example black text on green paper or red instructions on a form. Removing colors from the scan reduces the scan file size. You can select to filter out a color channel (red, green, or blue) or up to three specific colors. For specific colors, the sensitivity setting controls how closely a scanned color must approximate the specified color.
Solve performance problems Table 6-23 Solve performance problems Problem Solution Scanner will not turn on. Verify that power is being supplied to the scanner. The scanner power switch might be turned off. Be sure that the power switch located on the back of the scanner is turned on. The scanner might have been unplugged. Check to see that the power cable has not become disconnected from the scanner or unplugged from the power source. Scanner is scanning items very slowly.
Table 6-23 Solve performance problems (continued) Problem The imprinter is not printing or the print quality is poor. NOTE: To use the imprinter, load originals in the ADF. The imprinter cannot print on pages placed on the scanner glass. Control-panel buttons do not operate or behave unexpectedly. Solution ● If you are scanning a large number of pages at one time, consider scanning fewer pages at a time to create more, smaller files. ● Use the Kofax VirtualReScan software to process the scanned data.
Table 6-23 Solve performance problems (continued) Problem Solution NOTE: After each step, press a button to see if it is working correctly. If the problem persists, proceed with the next step. 1. On the Buttons tab of the HP Scanner Tools Utility, determine the associations for the Scanner Front Panel Buttons. If necessary, change the software that is assigned to a button. 2. Verify that the expected program is installed on the computer by looking at the Start menu. If necessary, install the program.
