How do I clear white vertical lines or streaks appearing on printed documents? pages


Description of Solution 200000024332

White vertical lines or streaks on printed documents can be caused by dirt or debris on the LED head or drum surface or a cloudy LED head. To resolve this issue follow the steps listed below:

 

1. Copy and paste the URL listed below and then print the test document.

http://welcome.solutions.brother.com/bsc/public_s/id/pdf_pub/hl3000/virgule_a4_rgb_10pt.pdf

 

2. The test document should have 4 diagonal colored lines; black, yellow, magenta, and cyan.  Examine the document to identify which LED head(s) and drum unit(s) require cleaning. This can be determined by looking for white spaces (void areas) in the lines.

 

For example, if there is a white space (void area) in the black line the black LED head and drum unit will need cleaning. If there are white spaces (void area) in more than one color line, the LED heads and drum units for those colors will need to be cleaned.

 

3. Clean the LED head(s) by following the steps listed below:

         

a. Power the machine off using the On/Off switch located on the right side of the machine.

 

b. Open the top cover using the blue handle in the center which is located below the control panel. A white arrow is in the center of the handle. Open the top cover until you hear a click.

 

c. The LED heads are located on the top cover. There are 4 LED heads, one for each color.  When the top cover is completely opened the 4 LED's are locked in a slanted position. To clean the LED, lower the top cover slightly down so the 4 LED's move to a vertical position.

 

d. Clean the LED that is causing the problem as identified from the test pattern. Locate the white color piece that has a barcode sticker on the right side; wipe the bottom of that piece using a soft dry, lint-free cloth. The black color LED is closest to the front of the machine, followed by Yellow, Magenta, and Cyan.

 

NOTE: Be careful not to touch the bottom of LED head with your fingers.

 

e. Close the top cover of the machine. You will hear a loud click when the top cover is closed firmly.

f. Power the machine back on.

 

g. Print your document again.

 

- If the problem continues go to STEP 4.

 

4. Clean the drum unit by following the steps listed below:

 

a. Power the machine off using the On/Off switch located on the right side of the machine.

 

b. Open the top cover of the machine.

 

c. Review the test document to identify the drum unit that needs cleaning.

 

- For example, if the white space (void area) on the test document is on the cyan color line, you should clean the drum unit for cyan. 

 

d. Remove the drum unit and toner cartridge assembly.  The drum unit and toner assembly can be removed by grasping the center of the drum and toner assembly and pulling it straight up.

 

NOTE: We recommend that you place the drum unit and toner cartridge assembly on a clean flat surface with a sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter toner

 

e. Push down the green-labeled lock lever and take the toner cartridge out of the drum unit.

 

f. Inside the drum unit there is a red roller. This is the OPC drum roller. Place the test document in front of the drum roller and find the exact position of the poor print (white space). Turn the drum unit gear, which is located on the left hand side with your thumb or finger while also looking at the surface of the OPC drum roller for any dust, label or glue like substance on the drum unit roller.

 

 When you have found the mark on the drum that matches the print sample, wipe the surface of the drum with a dry cotton swab until the dust or glue on the surface comes off.

 

If you are unable to locate any dust or glue on the surface, wipe the entire drum surface with a dry cotton swab.

 

g. Put the toner cartridge back firmly into the drum unit. You will hear it lock into place.

 

h. Reinstall the drum unit and toner cartridge assembly into the machine by sliding it into the correct slot by matching the toner cartridge color to the same color label on the machine.

 

i. Close the top cover of the machine. You will hear a loud click when the top cover is closed firmly.

 

j. Power the machine back on.

 

5. Print your document to see if issue is resolved. If the problem continues, and your machine is within warranty, you can locate a Brother Authorized Service Center (ASC) in your area by clicking on the link below:
