HP Designjet Scanner - Checkpoints Before Starting a Scan Job

Before starting a color scan reproduction job, you should answer the following questions to ensure you are in a correct state to proceed. If any of the answers are negative or uncertain, please follow the recommended actions.

Scanner:

Is the glass plate clean and free from dust?

If not, or not sure, please follow the scanner maintenance manual to clean it. Typically, vertical lines appear in the copy if the glass plate is not clean enough.

Is the white background element of the loading mechanism clean?

If not, the grays will show a color cast in the copy and the system will behave erratically (some copies will be acceptable whilst some others won’t).

Has the scanner been on for more than 1 hour?

If not, the colors may vary during the scan.

Does the scanner need to run the scanner maintenance process?

If so, follow the scanner maintenance manual. Typically, the scanner maintenance process should be run every 100 scans or once a month, but it depends very much on the type of originals being scanned. If it is suspected that the scanner may have a problem (colors very different from the original, grays not neutral, broken lines), then run the scanner maintenance process.

Has the original dried?

If the ink is still fresh, the original may be damaged and the glass plate of the scanner may be dirtied.

Is the height setting in the loading mechanism adapted to the thickness of the original?

If the original is thicker than 2 mm, please follow the guidelines in the scanner’s documentation and always remember to handle the original with care.

Touch screen:

Do you have a media profile adapted to the media currently loaded into the printer?

If not or not known, please create a media profile as described in the scanning system’s documentation. If it is not correct, the output image may have serious defects: too much ink (dark images, smearing, bleeding), too little ink (washed out, low contrast images), wrong colors.
