If horizontally aligned black streaks or smears 

appear:
• The toner cartridge may be installed improperly. 

Remove the toner cartridge and reinsert it.

• The toner cartridge may be defective. Remove the 

toner cartridge and install a new one. See 
page 8.4.

• If the problem persists, the machine may require 

repair. Contact a service representative.

If the printed paper is curled or paper does not feed 

into the machine:
• Turn over the stack of paper in the tray. Also try 

rotating the paper 180° in the tray. 

• Try printing to the rear cover.

Copies are too light or 

too dark.

Use Darkness to darken or lighten the background 

of the copies.

Smears, lines, marks, 

or spots appears on 

copies.

• If defects are on the original, use Darkness to 

lighten the background of your copies.

• If no defects are on the original, clean the scan 

unit. See page 8.2.

Copy image is 

skewed.

• Ensure that the original is face down on the 

document glass.

• Check that the paper is loaded correctly.

Blank copies print 

out.

Ensure that the original is face down on the 

document glass.

Image rubs off the 

copy easily.

• Replace the paper in the paper input tray with 

paper from a new package.

• In high humidity areas, do not leave paper in the 

machine for extended periods of time.

Frequent copy paper 

jams occur.

• Fan the stack of paper, then turn it over in the 

paper input tray. Replace the paper in the paper 
input tray with a fresh supply. Check/adjust the 
paper guides, if necessary.

• Ensure that the paper is the proper paper weight 

80 g/m

2

 (20 lb bond) paper is recommended.

• Check for copy paper or pieces of copy paper 

remaining in the machine after a paper jam has 
been cleared.

Toner cartridge 

produces fewer copies 

than expected before 

running out of toner.

• Your originals may contain pictures, solids, or 

heavy lines. For example, your originals may be 
forms, newsletters, books, or other documents 
that use more toner. 

• The machine may be turned on and off frequently. 
• The document cover may be left open while 

copies are being made.

The scanner does not 

work.

• Make sure that you place the document to be 

scanned face down on the document glass.

• There may not be enough available memory to 

hold the document you want to scan. Try the 
Prescan function to see if that works. Try lowering 
the scan resolution rate.

• Check that the USB cable is connected properly.
• Make sure that the USB cable is not defective. 

Switch the cable with a known good cable. If 
necessary, replace the cable.

• Check that the scanner is configured correctly. 

Check scan setting in the SmarThru Configuration 
or the application you want to use to make 
certain that the scanner job is being sent to the 
correct port, for example, LPT1.

The unit scans very 

slowly.

• Check if the machine is printing received data. If 

so, scan the document after the received data 
has been printed.

• Graphics are scanned more slowly than text.
• Communication speed slows in scan mode 

because of the large amount of memory required 
to analyze and reproduce the scanned image. Set 
your computer to the ECP printer mode through 
BIOS setting. It will help to increase the speed. 
For details about how to set BIOS, refer to your 
computer User’s Guide.
