Hello,

The most likely cause of the bad printing is the transfer roller part # RF5-4067. The transfer roller applies a charge to the paper so the toner transfers ok, if the roller is worn or damaged it will not charge the paper right and you will get print problems. This roller is located under the image drum. We have service manuals available if you need them.

There's probably some problems with the High Voltage Power Supply or DC controller.

Have a light stripe down center of copy, even after installing new toner cartridge? No Error message.


The most common problems are scratches or lines around the drum. These lines will transfer to the image. If the complaint is a solid or partial line on the image, inspect the drum for a matching set of lines. Replace the toner cartridge if the drum appears damaged or if you suspect the drum to be the cause of the image problem. If you replace the toner cartridge and the lines remain, then there's a good chance that the problem is with the drum.
The other part of the image subsystem which could cause this is the fuser. Scratches or damaged areas of the fuser can result in missing or smudged areas on the printout. Remove the fuser, and examine it closely for damage or deterioration. You can contact your printer manufacturer for a replacement fuser if necessary.

I hope this helps and thanks for using Fixya!

Constantly has black streak on page even after cleaning


Welcome to FixYa!

If you are experiencing black streaks or bands in your printout such as the image below, one or more print cartridges might be low on ink or defective. If you are using non-HP print cartridges, no messages will appear on the device control panel or in the HP Toolbox.

Since this is caused by low on ink or defective print cartridges, the best thing to do is to replace the print cartridges.

Thank you for using FixYa. Keep me posted.

My printer is smudging the left hand side of the printout. How do I clean it?


Check and verify smudging not caused by toner cartridge by removing toner from printer and checking the blue roller. DO NOT TOUCH the roller as oil from fingers may cause image defects. If toner good suspect fuser causing smudging on your printouts. Note fuser not considered a customer replaceable part for this model.

PRINT IS BLURRY


The printed output is fuzzy, blurry, or grainy, or the edges of objects in the images are jagged. Solution Follow these steps until the issue is resolved. Step one: Check your paper
  • Many papers have printing and non-printing sides. Load the paper with the printing side down.
  • Use the correct paper type for the project. For everyday documents, plain paper works well. For documents with dense printing, such as high-contrast graphics or photographs, use HP Advanced paper for the best results.
  • If these steps do not help, try a different paper. Ink might not bleed as easily on heavier paper. Paper that does not accept ink well is also prone to bleeding and smearing. HP designs its inks and papers to work together.
Step two: Check the settings
  1. In the program being used for printing, click File , and then click Print . The Print window opens.
  2. Make sure the appropriate product is selected, and then click Preferences or Properties . The Preferences/Properties window opens.
  3. Click the Printing Shortcuts tab. Consider modifying some or all of the options in the Printing Shortcuts menu to increase print quality.
    • Print quality : If the quality of the printouts is not acceptable, try increasing the print quality. To print more quickly, try decreasing the print quality.
    • Paper type : If one of the options matches the paper type exactly, select it instead of Automatic .
    • Paper size : Make sure that this option matches the paper loaded in the product.
    To see additional options, click the Advanced tab, and then click Advanced Features . The Advanced Features window opens. Consider changing the following option: Ink volume : Adjust the amount of ink that prints on a page. For lighter images (less ink), drag the slider to the left. For darker images (more ink), drag the slider to the right. The lighter the ink volume, the more quickly the printout dries.
Step three: Check image resolution Make sure that the image file has enough resolution for the size of the printed picture. Although many photo applications can enlarge an image or part of an image to any size, eventually the individual pixels become visible and the whole image looks blurry. Here are some general guidelines for image file resolutions:
  • 94 pixels per cm (240 pixels per inch) for images to print on smaller format photo paper, such as 10 x 15 cm (4 x 6 inch)
  • 117 pixels per cm (300 pixels per inch) or higher for larger format photo papers
  • Lower resolutions might produce acceptable images when printed on rough-textured paper
Step four: Align the cartridges If the previous steps have not improved the appearance of the printout, align the cartridges. See the user guide for alignment instructions.

Deteriorating image quality


Good Evening Robert,

The setting for non dell toner only controls the fuser temperature, and will not cause you any print quality issues. Toner is actually made up of ink and plastic. The fuser melts the plastic to "fuse" the image to the paper. Dell toner is set to "fuse" at a specific temperature. when you use non Dell toners, the temperature required to fuse may be different, and when set to non dell toner setting, the fuser temperature is raised to the maximum to ensure the other toner fuses properly. The down side to this is that you will wear out the fuser sooner then it should.

As far as the print quality issue you are having, it is most likey caused by the imaging drum.

Regardless of the estimated life for the imaging drum as stated by the printer, this is just an estimate. Many things can and will cause the imaging drum need replacing. ( Just yesterday I replaced a black toner in a 3115 that was less then a month old... genuine Dell... with more then 75% expected usage left because it was defective).

On this printer, each of the 3 colors and the black are all independent of each other with the exception of the imaging drum. Even within the imaging drum, cyan and black are independent of magenta and yellow on the first stage of transfer. When you have deteriorated print quality that effects more then one color, the first step is to replace the imaging drum.

The Primary transfer, secondary transfer, and tertiary transfer of the image are ALL contained within the imaging drum.

The chances of having 3 or 4 bad Developers is very very slim. If your print quality issue was related to only ONE color, then I would say you had a bad developer unit ( the 4 items located behind the imaging drum when removed). These are far more difficult and expensive to change.

The BTR ( bios transfer roller ) is the only other item that "could" effect your print quality, however, based on the symptoms you discribed, I doubt it. Besides, if i am not mistaken, the imaging drum kit comes with a new btr anyway.

Although I am sure you may be disappointed with the fact the drum unit is failing while showing it still has life remaining, the solution to replace it should restore your unit to full operation. The unit is light sensative, and effected by physical age as well as the number of prints it has supplied.

Please evaluate the solution i have provided and, rate the solution appropriately to show your support.

Thanks,
Cory

Yes Cartridge problem is what causes double imaging 95 % of the time, there is a rubber blade in the drum unit that wears and doesn't clean off old image from drum. Have known this fault to be fuser at times, the way to tell is to get a print to stop half way threw machine by openning door during print, remove cartridge and look at print, you want it to be stop before the fuser(hot bit) but after the drum, image still rubs off if pre fuser and then you can see if defect is present before paper travels threw the fuser, but in your case I think you will find it is not the fuser it is toner cartridge.

My printer prints blurry lines!


Try this: make a copy and stop it when it reaches the cartridge ( has to have image on paper) take out paper and look at it, does it have blurry copies? if yes, then the problem is with the cartidge or (worse) the laser printing device ( expensive).
Take a chance and replace the cartridge.  if still there you need to replace the laser unit.

If it does not have blurry copies when you stop it at the drum then check the fuser unit( doubt it ) to see it it has any writing or toner on it.

Good Luck.

Printouts with shadow


Two things - Fuser or cartridge - stop print halfway in machine, if fault occurs before paper has gone threw the fuser then it is a faulty cartridge, if print is ok before fuser (the hot bit at rear) but gets doubled up after fuser then the hear roller in fuser are faulty change fuser....but 95 % of the time it is due to dodgy refill cartridge or worn cartridge (the rubber blade inside cartridge fails to apply enough pressure against drum to clean away old image  hence duplicating itself onto your nice clean paper! Try a known good cartridge if in doubt..
