HP m410n laserjet pro banding gray vertical lines


the two places to look is transfer roller and the fuser unnit.
i think there is a problem with the transfer roller it is under the toner and it needs to be spring loaded. The paper passes between the toner an the transfer roller to charge the paper en let the toner stick to the paper and if it doesn't make correct contact then it wont work

Vertical white lines on page after printing


There will be something covering a small patch of the laser mirror. Find the laser mirror inside the machine (Normally above where the cartridge sits) and wipe this with a clean cloth. Other than taking the cartridge out there is no dissassembly required.

I think i have a fuser error. When I print something the right side of the paper is very light in color. If I print multiple pages, it gets lighter by every page.


Put paper in the manual feed tray. Print. When the page gets half way into the printer, open the cover. Remove the toner. Look down at the paper. Is the right side lighter than the left? If yes, replace the toner cartridge. I don't believe that a fuser could cause your problem.

Hp 4550 vertical line down center of page


From the service manual:


Vertical lines or streaks
 Check for a leak where light might be entering the printer.
 Check for circumferential scars on the photosensitive drum. If scars are present, replace the
drum cartridge if the line goes through all colors.
 Check for circumferential scars on the upper fusing roller. If scars are present, replace the upper
fusing roller if the line goes through all colors.
 Remove the imaging drum and inspect main charger or imaging drum for a contaminant, such as
a fiber, if the line goes through all colors.
CAUTION Do not expose the imaging drum to light for more than 15 seconds. The drum is light sensitive, and
exposure to light can cause permanent damage.
Vertical black lines
 The toner cartridge is defective.
 The toner cartridge is not seated properly.
 The fuser entrance is dirty.
 The fuser has scratches on it.
 This might be a repetitive defect. If so, the lines will repeat at a consistent interval down the page.
 The printer needs to be cleaned.
 There is a problem in the heating element.
Vertical white lines
 If white lines or streaks appear only in the black areas of the printed media, print several
configuration pages to clear the anomaly. If this does not clear the problem, check the sleeve
surface to confirm the defect, then replace the black toner cartridge.
 If white lines appear only in a particular color, try printing several configuration pages to clear the
error. If the error does not clear, check the sleeve surface to confirm the defect, then replace the
defective toner cartridge.
 There is a lack of toner or the toner cartridge is faulty.
 There is dirt in the laser path.
 The fuser is defective.
 A mirror in the laser scanner is dirty.

Print quality bad


To clear white vertical lines from printed documents follow the steps listed below:

NOTE: The use of non-Brother or generic toner may cause white vertical lines.

Brother strongly recommends that customers do not use generic drum units and/or toner cartridges, or refill their Brother toner cartridge. Each Brother laser printer is designed to work at pre-set temperatures that are matched exactly to each of our individual toner formulations. Each individual component is designed to work with the other to ensure quality and reliability. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability.
The Brotherlimited warranty does not apply to any problem that is caused by the useof unauthorized third party drum units, toner cartridges or toner.

1. First, power OFF the unit for safety. The ON/OFF switch is located on the left, rear side of the unit.

2. Open the scanner cover by pulling the blue lever located below the control panel toward you and lifting the cover. Make sure the cover is completely open.

3. Remove the drum unit by holding each side of the drum by its handles and gently lifting the drum forward (toward) you.

4. Place the drum unit on a drop cloth or large piece of disposablepaper to avoid spilling and scattering the toner. Make sure thedirections and DR-250 stickers are facing you.

5. With the drum removed from the Brother machine, clean the laser glass. The laser glass is located inside the Brother machine where the drum was located. It is a piece of glass, about 1/2 inch wide and approximately 8 inches long, located on the bottom of the inside. Gently wipe the glass with a clean soft DRY cloth. DO NOT use isopropyl alcoholor any liquid to clean the glass.

6. Gently pull up on the mauve lever to turn the toner cartridge toward you until it stops. Remove the toner cartridge from the drum unit by gently sliding it out of the drum unit. ***Handle the toner cartridge carefully. If toner scatters on your hands or clothes, immediately wipe it off or wash it with cold water.

7. Gently rock the toner cartridge from side to side five or six times to distribute the toner evenly inside the cartridge. Then, reset the toner into the drum (be sure it clicks into place). Gently push on the mauve lever to turn the toner cartridge away from you until it stops.

8. With the DR-250 sticker facing you turn the drum upside down. There is a blue tab located on the right side. Slide the blue tab back and forth seven times to clean the corona wire. When finished, make sure the blue tab is locked to the right side of the drum.

9. Reset drum unit in Brother machine. Close the cover securely.

Print the help list to test the unit by pressing the REPORTS key located on the control panel and then (1) on the dial pad.

If the white vertical lines still continue, the drum unit will need to
be replaced.

If the purchase date of the original drum or replacement drum is less than 90 days (within the warranty of the drum), contact Brother Customer Service Center at 1-877-Brother (1-877-276-8437) . The center is open Monday-Friday, 9:00am to 7:00 pm EST, excluding holidays.
