HP T2500 Vibration

The two images below are examples of the stop-start effect when the above image is scanned. Please note the black arrow indicating the scanning direction in these examples.

Actions

1.Clean and calibrate your scanner as indicated in Scanner maintenance on page 156. Scan your original again and make sure that the printer is not working while you are scanning. Reduce scanning resolution (choose Standard if scanning, Fast if copying) if necessary.

2.If the problem persists, proceed to analyze patterns 4, 13, and 14 of the diagnostic plot. If you find a problem similar to that shown below, call HP support and report a “stop-start effect” error.

Vibration

If your printer is not properly placed on a flat surface, or if the scanner lid does not close correctly, you may sometimes find that the scanned image suffers from vibration, as in the following example: original on the left, scanned image on the right.

1.Make sure that the scanner is placed on a flat surface, the scanner lid is correctly closed, and the printer is not working while you are scanning. Scan your original again.

2.If the problem persists, change (increase or decrease) the scanning resolution and re-scan your original. We also recommend turning the original 90 degrees before scanning it again.
