Black smudges down left side of page


How do I clean white or black spots on printed documents? Description: First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:

  1. Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
  2. Position the print sample in front of the drum unit so you will know the exact position on the drum that is causing the poor print.
  3. all-ug-19.gif
  4. Turn the black gear on the drum as you check the surface of the OPC drum.
    The OPC drum is photosensitive so do not touch it with your fingers.
  5. all-ug-20.gif
  6. When you find the substance on the drum surface that matches the print sample, gently dab the surface of the OPC drum with a cotton swab that is lightly dampened with isopropyl alcohol.
  7. Note
      • Do not use a scrubbing or wiping motion because this might damage the drum.
        all-ug-21.gif
      • Do not try to clean the surface of the OPC drum with a sharp object, such as a ball-point pen, because this might cause permanent damage to the drum unit.
  8. If the print quality still has not improved you need to install a new drum.

Troubleshooting common laserjet printers problems


In order to understand and troubleshoot a Laserjet printer, I think it is important to understand how the printer functions. Laser printers for the most part contain some standard assemblies: Toner cartridge, Laser Scanning Assembly, High Voltage Power Supply, DC Power Supply, Paper Transport Assembly, Transfer Corona Assembly, Fusing Assembly, Printer Controller Circuitry, and Ozone Filter.
A laser printer undergoes a six step process that helps form images on paper. The six major steps are:

1. CLEANING- This is the first step in the process in which a rubber blade inside the printer cartridge scrapes any toner left on the drum into a used toner receptacle inside the cartridge. A fluorescent lamp discharges any remaining charge on the photosensitive drum (the photosensitive drum or EP drum loses its charge when exposed to light).

2. CHARGING- A special wire called the charging corona within the toner cartridge located above the photosensitive drum receives a high voltage from the High Voltage Power Supply. This high voltage is used to apply a strong , uniform negative charge to the surface of the drum.

3. WRITING- The laser is turned on and scans the drum from side to side, flashing on and off according to the bits of information the printer controller sends as it communicates the individual bits of the image. Where ever the laser touches, the photosensitive drum's charge is reduced to a slight negative charge. As the drum rotates, a pattern of the exposed areas is formed, representing the images to be printed.

4. DEVELOPING- Now the surface of the drum holds and electrical representation of the image being printed. Toner can now be transferred to the areas that were exposed in the writing step. A metallic roller called the developing roller inside the cartridge now acquires a charge from the HVPS. The toner sticks to this roller because there is a magnet located inside the roller and because of the electrostatic charges between the toner and the developing roller. The developing roller rotates toward the EP drum, the toner comes between the the developing roller and EP drum and is attracted to the areas that have been exposed by the laser and the toner is repelled by the areas that were not exposed to the laser. The EP drum continues to rotate until the developed image is ready to be transferred to paper.

5. TRANSFERRING- The developed image into position. The controller notifies the registration rollers that the paper should be fed through. The rollers move the paper underneath the EP drum, and the transfer process can begin. The controller sends a signal to the corona wire or corona roller (depending on which the printer has) and tells it to turn on. The corona wire/roller then acquires a strong positive charge from the HVPS and applies it to the paper. Now that the paper is charged, it pulls the toner from the EP drum and the line of contact between the roller and the paper. Once the rollers move the paper past the corona wire, the static-eliminator strip removes all charge from that line of paper.

6. FUSING- This is the final step in the process where the toner image is made permanent. The roller push the paper toward the fuser rollers. The fuser rollers grab the paper and is now in control of the paper. As the paper passes through the fuser, the 180 degree fuser roller melts the resin of the toner, and the rubberized pressure roller presses it permanently into the paper. The paper continues on through the fuser and then exits the printer.

The following picture will give you a general idea of the process and components.

TROUBLESHOOTING:

PAPER JAMS- These are by far the most common problem encountered by all printers at one point or another. Some common causes of paper jams are as follows:

1. The paper is wrinkled or has upturned edges, the wrong type of paper is used, the paper is not place properly in the feed tray (usually not even).

2. If paper jams start happening at a frequent rate then the problem could be a worn roller (which can be replaced and are not that expensive). The following pictures shows the rollers.

6a2eae9.jpg

3. Anther cause could be related to the drive gear of the pickup roller, shown here:
381b1a8.jpg


BLANK PAGES:

If your printer is printing nothing but blank pages, then the toner is not being put on the paper. There are three major causes for this happening.

1. The toner cartridge could be empty or if you have just bought a new cartridge it is possible that you purchased a defective one. If you forget to remove the sealing tape the toner will not be able to be accessed properly by the printer.

2. The Corona Assembly could have a malfunction such as a missing or damaged corona wire. If this is the case the developed image will not transfer from the EP drum to the paper. The following is a picture of Corona Assembly:
423433f.gif

3. Another cause is the High Voltage Power Supply. If the power supply does not charge the components with the proper voltages. Picture of an HVPS:
451fd29.jpg

REPETITIVE SMALL MARKS OR DEFECTS:

This usually happens with heavily used or older laser printers. The following could be causing the problem.

1. Toner may have been spilled inside the printer.

2. A chip or crack in the EP drum can be another cause which can cause a toner build up and can get stuck on one of the rollers. EP drum picture:
f036288.jpg

VERTICAL BLACK LINES ON THE PAGE:

This can be caused by the following:

1. A groove or scratch in the EP drum.

2. A dirty Corona Wire which prevents a sufficient charge from being placed on the EP drum.

VERTICAL WHITE LINES ON THE PAGE:

The number one cause is the following:

1. This usually happens when proper cleaning and maintenance is not performed on the printer. Foreign matter gets caught on the transfer Corona Wire.

IMAGE SMUDGING:

This happens when you pick up a paper that has just come out of the printer and when you touch the ink, it smudges or smears.

1. The fuser could be malfunctioning or need replacement due to a burnt out halogen light inside the heating roller.
87c0647.jpg

2. Dents or cold spots in the fuser heat roller can also cause the problem.

GHOSTING:

Ghosting is what you have when you can see light images of previously printed pages on the current page. Usually one of two things cause this problem.

1. Bad erasure lamps. This causes the previous electrostatic discharges to not be completely wiped away.

2. A broken cleaning blade. This causes old toner to build up on the EP drum and presents itself in the next printed image.

PRINTER PRINTS PAGES OF GARBAGE:

This happens when the print on the paper comes out like garbage and is not understandable or looks like some government secret code on the page. The following are usually the causes.

1. The printer driver software is not the proper driver for the printer or it is not configured for the correct page-description language (PCL or PostScript).

2. A bad formatter board. Remember the formatter board receives information from the computer and turns it into commands for the various components in the printer.

I have a Xerox Copier XC1045. Our copies are coming out with dark spot on the paper., I change the drum, but still have same problem, even big area has black spot


You may have a worn out heat roller in the fuser.
It is also likely you have a bad toner cartridge . If the spots are gritty then replace the toner cartridge and vacuum out the machine,

Spots on paper


There is limited information about this problem.
Whenever performing any servicing on the machine on your own, unplug the machine from the wall, First!
If there is competitive toner used in this machine, try using a different manufacture. Use the original manufacture that makes this machine first.
The entire toner has to be taken out and complete vacuumed. The developer housing needs to be completely free of any competitive toner.
Install the new original manufacture toner. Make sure it is from the manufacture themselves
The base of the machine inside needs to be clean because the toner will drop on the paper tray, this will cause paper jams. The toner drops and contaminates the feed rolls making them slip on the paper.
Extra care needs to be used when cleaning below the developer housing, especially by the Transfer corotron. If one breaks this wire, the entire corotron channel needs to be replaced.
This corotron assemble can cause different problems when it is not working. Light copies, faded copies with some images on the paper is an indication this transfer corotron is not working properly.

If the fuser assembly looks like it is in poor condition, the best thing would be to replace it. This fuser modual has stripper fingers that wear and will not take the paper off the heat roll properly. If the heat roll has a coating of toner on it, this toner will ride against the heat temperture thermister sensor. At this point, the temperature sensor is not working properly and can even shut down the machine due to poor heat sensing.

Do not try to clean this sensor.

A new fuser assembly would be the right choice.
The new assembly also has a number on top of it, either it is circled or just stamped. This needs to be entered into the machine for proper fuser operating temperature.

For better servicing have a trained service representative service the machine by the original manufacture.
This is a good machine if it has been good to you in the past.
Pay the price and be safe.
Good luck.

4250tn print black spot


You either have a bad spot on the drum or a bad spot on the fuser rollers. Replace the cartridge first. If spot continues, take cartridge out and get inside with a flashlight. You'll probably find a piece of paper stuck to a roller.

Have you tried the toner cartridge?? IF not please do so. Failing this clean out the middle of the machine with a dry cloth as you may have loose toner in there. Try this if it doesn't work then the laser unit may have a fault.

Hope the first one helps
Thanks J

Copies come out smugged


There are several things you want to check before you go replacing the fuser that usually just burns out and when it does all the panel lights flash at the same time. The problem you are describing is more likely excessive toner build-up check when the printer is off to see if there is a ridge of toner caked up where the paper enters the fuser assembly if so this can be scraped off carefully so as not to damage the fuser itself. Clean the transfer roller also or lastly clean the laser printhead itself it is able to be reached after removing the toner cartridge and using a DRY soft cloth to wipe back and forth along the fingerwide slit inside on the top of the printer. Also a defective/empty toner cartfidge could be to blame.

good luck

Large grey streak down center of page


It is the fuser at rear giving you grief! The upper heat roller has a teflon coating that wears away allowing toner to stick to roller and smudgin prints as they pass threw it. The fix is to replace fuser assembly, take to brother dealer to fix.

You can prove it to yourself by timing the print to stop mid way threw machine then remove print cartridge and look at paper, you should see a image is good untill it hits the fuser,( pre fused image "rubs off" paper.) If you have changed drum and toner thats all it can be. They all do it in time.

Fuser is hot bit at rear, pull out drum and look in the back with a small torch you will see upper heat roller is worn, guestimation $90 for fuser plus labour to fit.

There is no model number or brand mentioned, but it may need a new drum kit. Also, sometimes the fuzer module is dirty.
