Make sure that the type and quality of the paper you are using meet

 

 

 

 

 

 

 

 

 

 

HP specifications. For more information, see the product user guide.

 

 

 

 

 

2.

Make sure that the environmental specifications for the product are being met.

 

 

 

 

 

 

See Environmental specifications on page 309.

 

 

 

 

 

3.

Turn over the paper in the tray. Also, try rotating the paper 180°.

 

 

 

 

 

4.

Do not use paper that already has been run through the product.

 

 

 

 

 

5.

Decrease the toner density. Open the CONFIGURE DEVICE menu at the

 

 

 

 

 

 

product control panel. Open the PRINT QUALITY submenu and change the

 

 

 

 

 

 

TONER DENSITY setting. For more information, see the product user guide.

Random image

 

 

 

 

If an image that appears at the top of the page (in solid black) repeats further down

 

 

 

 

repetition

 

 

 

 

the page (in a gray field), the toner might not have been completely erased from the

 

 

 

 

 

last job. (The repeated image might be lighter or darker than the field it appears in.)

 

 

 

 

 

 

 

 

 

 

●

Change the tone (darkness) of the field that the repeated image appears in.

 

 

 

 

 

●

Change the order in which the images are printed. For example, have the

 

 

 

 

 

 

lighter image at the top of the page, and the darker image farther down the

 

 

 

 

 

 

page.

 

 

 

 

 

 

 

 

 

 

 

●

From your software program, rotate the whole page 180° to print the lighter

 

 

 

 

 

 

image first.

 

 

 

 

 

●

If the defect occurs later in a print job, turn the product off for 10 minutes, and

 

 

 

 

 

 

then turn it on to restart the print job.
