Pull out the cartridges. Wet a q-tip with alcohol and clean the foil contacts that are in the spaces that the cartridges just occupied. Use a flashlight to better see what you are doing. See if that helps.

And what kind of lines are you getting on the printout? Vertical?Horizontal? Those could be ink that is on the feed rollers.

You don't need to do head alignment, because it is for vertical banding in printout. Vertical banding can be minimized by disabling high speed option without doing head alignment. If your printout have horizontal white lines, do check nozzle and head cleaning, or you can minimize white lines by printing in best quality (photo).

Step one: Retry the print job The problem may occur only rarely. If you have not seen it in other printouts, try again. Step two: Increase the print quality mode If reprinting did not help, try increasing the print quality mode.

1. In the application you are printing from, click File , and then click Print .
2. Make sure the printer is selected, and then click Properties .
3. Select the Paper/Quality tab.
4. In the Print Quality area, choose the next higher quality setting. If the current setting is Draft, choose Normal. If the current setting is Normal, choose Best.

Step three: Print in grayscale (black area streaking only) If the streaks are in a black area of a black and white printout, change to grayscale printing. NOTE: This step does not apply to color printouts.

1. In the application you are printing from, click File , and then click Print .
2. Make sure the printer is selected and click Properties .
3. Click the Color tab, and select Print Grayscale and High Quality .

Step four: Clean the printheads If the print quality is still bad, clean the printheads.

1. Make sure the printer is loaded with unused white paper.
2. Open HP Solution Center .
3. Click Settings , Print Settings , and then select Printer Toolbox .
4. Click the Service Tab .
5. Click Clean Printhead , and then click Clean .

Step five: Align the printheads If the print quality is still bad, align the printheads.

1. Make sure the printer is loaded with unused white paper.
2. Open the printer Toolbox , and select the Printer Services tab.
3. Click Align Printheads . The Align Printheads window opens. Click Align .
4. The printer prints an alignment page. The lines in the patterns should appear to be straight. Click OK when the page finishes printing.

Step six: Calibrate the linefeed If the print quality is still bad, calibrate the linefeed:

1. Make sure the printer is loaded with unused white paper.
2. Open the printer Toolbox and select the Printer Services tab.
3. Click Calibrate Advanced Linefeed . The Advanced Linefeed Calibration window opens. Click OK .

Step seven: Replace one or both printheads If the print quality is still bad after performing all the above steps, one or both of the printheads will have to be replaced. Print a PQ Diagnostic page to see which printhead should be replaced.

1. Make sure the printer is loaded with unused white paper.
2. Press the Setup button.
3. Press 1 and * simultaneously.
4. Look at the color blocks labeled Test Pattern 2. Some or all of them could show white horizontal streaks. If none of the blocks are streaked, the printheads are okay.
   • If the Black block has lines – replace the KY printhead.
   • If the Cyan block has lines – replace the MC printhead.
   • If the Magenta block has lines – replace the MC printhead.
   • If the Red block has lines – replace the KY printhead.
   • If the Green block has lines – replace the KY printhead.

Hav you replaced with original cartridges or 3rd party/refilled ones? This is a common problem when using generic/refilled cartridges. Let me know that first..

When you say poor quality, do you mean faded printouts, or broken print? Kindly explain in detail, so I can assist you further.

I would say you have a bad drum / toner cartridge.

Stuff you receive with vertical lines is probably the sender's dirty scanner.

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

hey payne


here is a copy of your problem.

Issue The printer is working, but colors in the printed output are missing, faded, or dull in comparison to the original. Solution Step one: Check the paper Verify that the paper type is appropriate for the project. If the paper is too fibrous, the ink applied by the printer might not fully cover the print surface. Step two: Check the print settings

1. In the software application you are trying to print from, click File and then click Print . The Print dialog box opens.
2. Verify that your printer is selected and then click Properties . The printer Properties dialog box opens.
3. Click the Printing Shortcuts tab.
4. In the What do you want to do? menu, select a task. The What do you want to do? menu lists most printing needs, but you might need to modify some of the options. Options on the Printing Shortcuts tab include:
   • Print quality: If you are unhappy with the quality of your printouts, try increasing the print quality. To print more quickly, try decreasing the print quality.
   • Paper type: If one of the options matches your paper type exactly, choose it rather than Automatic.
   • Paper size: Make sure this matches your paper.
   Additional options: click the Basics tab, then click Advanced Features . The Advanced Features window opens.
   • Ink volume: Adjusts the amount of ink printed 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 faster the printout will dry.
   • Dry time: Provides extra drying time for slow-drying printouts. Drag the slider to the left for less drying time, or to the right for more drying time. The printer will hold onto the printout until the dry time has elapsed.

Step three: Check the ink levels NOTE: If you have installed a refilled or remanufactured print cartridge, or a cartridge that has been used in another printer, the ink level indicator will be inaccurate or unavailable.

1. Open the Printer Toolbox .
   1. Open HP Solution Center .
   2. Click Settings .
   3. Click Print Settings .
   4. Click Printer Toolbox .
   NOTE: You can also open the Printer Toolbox from the Print Properties dialog box. In the Print Properties dialog box, click the Services tab and then click Service this device .
2. Click the Estimated Ink Levels tab. Figure 1: Estimated ink levels - both cartridges low

If the steps above have not resolved the issue, print and evaluate a self-test page to determine if the cartridges or printer is causing the problem.

1. Load the input tray with unused plain white paper.
2. Press and hold the Cancel ( ) button and then press the Start Copy Color ( ) button.
3. Release both buttons. The self-test page prints.

Step five: Note which cartridges printed which areas of the self-test page You must identify which cartridge printed which part of the self-test page, so that if you find defects on the page, you will know which cartridge is the problem. However, you can install different combinations of print cartridges in your printer, and different cartridge combinations print different self-test page patterns. Your self-test page may not look exactly like the picture below, but the right and left cartridges will print in the same areas of the page no matter which cartridges are installed. Step six: Look for defects In general, if the printer and print cartridges are working properly, the patterns (which look like grids of lines) should contain few or no missing lines. None of the colors should be missing and the colors of the blocks at the bottom of the page should match the labels below each block. Also, there should be no streaks of ink on the report. Missing lines or streaked bars If a pattern shows more than a few missing lines, or a bar is streaked, that print cartridge is not functioning properly. Figure 4: The magenta pattern shows missing lines and the bar is streaked

If you are using original cartridges then there should not be a problem. The horizontal lines come from the cartridge. Can you pinpoint if it is a color or black line that is missing? My guess is that during the alignment procedure, you are asked to choose a number or letter that corresponds to picture of a the lines that show the best alignment. If you did this correctly, may I ask how many pictures you printed before seeing that line. Is it on the first print or 10th printing? Cuz if it is on the 5th or more full color picture, then the problem is that you you really have the wrong printer. The F380 capacity for printing full color pictures is miniscule. 1 ml per color. So usually after the 3rd color picture, the ink starts to run out. Let me know if this helps.

Did u use the original ink cartridges or compatible ones or refilled?
