   TROUBLESHOOTING AND ROUTINE MAINTENANCE

If you are having difficulty with your DCP

If the copy looks good, the problem is probably not your DCP. Check 
the chart below and follow the troubleshooting tips.

DIFFICULTY

SUGGESTIONS

Printing

Condensed print and 
horizontal streaks or the top 
and bottom of sentences are 
cut off.

If the copy looks bad, clean the scanner area. If there is still problem, call 
Brother or your dealer for service.

Poor quality print.

See 

Improving the print quality

 on page 14-14.

Vertical black lines

Your DCP’s primary corona wire for printing may be dirty. Clean your 
primary corona wire (See 

Cleaning the drum unit

 on page 14-23).

Copy Quality Difficulties

Vertical streaks appear in 
copies.

Sometimes you may see vertical streaks on your copies. Either the 
scanner or the primary corona wire for printing is dirty. Clean them both. 
(See 

Cleaning the scanner

 on page 14-21 and 

Cleaning the drum unit

on page 14-23.)

Printer Difficulties

The DCP does not print.

Check the following:
• The DCP is plugged in and the power switch is turned On. (See the 

Quick Setup Guide.) 

• The toner cartridge and drum unit are installed properly. (See 

Replacing the drum unit

 on page 14-29.)

• The interface cable is securely connected between the DCP and 

computer. (See the Quick Setup Guide.) 

• Check to see if LCD is showing an error message. (See 

Error 

messages

 on page 14-1.)

The DCP prints unexpectedly 
or it prints garbage.

Reset the DCP or turn it off and then on again. Check the primary 
settings in your application software to make sure it is set up to work with 
your DCP.

The DCP prints first couple of 
pages correctly, then some 
pages have text missing.

Your computer is not recognizing the printer’s input buffer full signal. 
Please make sure to connect the DCP cable correctly.

The DCP cannot print full 
pages of a document.

Out of Memory

 message 

occurs.

Reduce the printing resolution. Reduce the complexity of your 
document and try again. Reduce the graphic quality or the number of 
font sizes within your application software. 

My headers or footers appear 
when I view my document on 
the screen but do not appear 
when I print them.

Most laser printers have a restricted area that will not accept print. 
Usually these are the first two lines and last two lines, leaves 62 
printable lines. Adjust the top and bottom margins in your document to 
allow for this.
