94 Troubleshooting and maintaining

Copies are too light.

￿

If you are copying an item printed on colored paper, there might

 

not be enough contrast between the ink and paper colors. Adjust

 

the highlights, shadows, midtones, and resolution settings from

 

the HP Precisionscan Pro software. See "Scanning from HP

 

Precisionscan Pro" on page 39. Or, adjust the contrast from the

 

HP Scanjet Copy Utility. Also, if possible for text, use originals

 

printed with black ink on white paper.

￿

The printer might be out of toner or ink. Print a different file from

 

another program to the printer to see if the issue lies with the

 

printer.

Vertical white stripes appear on the page.

￿

The printer might be out of toner or ink. Print a different file from

 

another program to the printer to see if the issue lies with the

 

printer.

￿

The scanner internal mirror might be contaminated. Contact the

 

Customer Service Center for service.

The bottom of the printed page is blank, or part of a graphic is cut off.

The page might be too complex. (The printer does not have enough memory to process the page.) Set the resolution of the image to 300 dpi or less in the HP Precisionscan Pro software. See "Changing resolution" on page 46.

Colors in printed images are incorrect.

The output type or printer settings might not be correct. Choose a different output type and print again. Check the printer settings. If it is a color printer, check if the printer is out of ink or toner.

Scanned images are jagged or fuzzy.

￿

The output type in the HP Precisionscan Pro software might not

 

be set correctly. Set the output type to True Color (16.7 million

 

colors) or Grayscale. See "Selecting output type" on page 43.

￿

If you placed the image in a file in another program, resized the

 

image, and are printing from that program, resizing the image in

 

the program probably caused the issue. Resize in the HP

 

Precisionscan Pro software before placing it in a file in another

 

program. See "Resizing (output dimensions)" on page 45.

￿

If the original image was fuzzy and you enlarged it, the fuzziness

 

becomes more obvious.
