Media “trees,” wrinkles, stacks poorly, or curls

 

 

 

FRU

 

Action

 

 

 

Fuser

 

This problem is most likely due to a worn backup roll. It causes the printer to run hotter than

 

 

required for the media being printed. Excessive heat can cause media treeing problems,

 

 

poor stacking, or curl.

 

 

Print the menu sheet found under Utilities.

 

 

Look at the media settings. Some, such as card stock or rough texture, may require a

 

 

higher fuser temperature, which leads to more of these problems (except stacking) in plain

 

 

paper.

 

 

• Change settings using the printer driver.

 

 

• Use the local printer setup utility (included on the CD) to change the NVRAM

 

 

settings.

 

 

Try a different ream of paper. Moist media has a higher tendency to crease (treeing) and

 

 

curl.

 

 

 

Parallel or USB port service check

1.Perform a print test to make sure the printer prints correctly. Verify that the indicator light is on, then print the menu settings by selecting Print Menu under Utilities.

2.Be sure the printer parallel cable is designed for bidirectional printing.

3.Be sure the user’s application is set up correctly.

4.If the internal print test page prints correctly, the user’s application/printer driver is set up correctly, and the correct bidirectional parallel cable is installed, but the printer still fails to print on command from the host computer, then replace the controller board.

5.Check the USB cable for continuity.
