Line down center of page.

I have a line down the center of the page when I copy a document. I have changed the DRUM and also the Ink Cartridge. This line only happens when I copy something myself - not on any incoming faxes. Thanks, Sherrey

Hi Sherrey, I think I can help! If you open the ADF cover where you insert your pages to make a copy. You will see a scanner glass about 1/2 inch wide and runs across the width of the printer. You can take a soft towel and some glass cleaner and clean the glass. There will probably be some white build up that looks like white out on the glass just make sure you clean it very well. I hope this helps!!!!

When making copies af a document a black line is showing on the bottom of the copied page. How can we fix it.

Clean the document laying flat glass with micro fiber cloth.

Pull out the toner/drum assrmbly and clean the drum with same cloth. Turn the drum using black circular dial on the side and clean it. Do not touch the drum. Also, change the toner cartridge if you have not for long time. This mostly happens when the cartridge is about to run out of toner ink powder.

hope this helps.

It say drum end soon and i dont know what this means as i put a new ink cartridge in it and it still keeps coming up the same.

Your unit obviously has a separate drum and toner.
Changing the toner, doesn't change the drum.
You will need to change the drum soon.

Black line down the center down the page

If it is a lazer printer a score on the photosensitive drum will leave a black line. Sometimes it is less grevious cace of an accumulation of ink leaving a line around the drum. This can happen when printing many dark background or full bleed copies. These drums are seensitive but can be carefully cleaned. Work away from direct strong light.

I guess that you get a white line when you are printing a document or receiving a fax....

The drum unit is scratched and needs to be replaced. Most of these printers have the drum unit as part of the cartridge; thus replacing the toner should solve your problem.

I will give you all the reasons I can think of.
1, If the line is only there when running through a document feeder and not there off the glass. The small strip of glass directly under the document feeder is dirty.
2. The drum has a scratch on it, or the cleaning blade is not cleaning the drum properly. Would require that cartridge replacement.
3. The fuser roller may be work in the middle. You would notice some reprinting , or ghost copying if that were bad.
4. Less likely would be some piece of fuzz in the light path, or a small piece of paper or tape in the paper path smearing the ink across the page.
If your machine prints, see if the line is on a print, if its on a print and not on the copy then it is scanner related.

My printed and copied pictures have horozontal lines

White lines through copies White lines can appear on a copy in either a horizontal or vertical direction. How the white line appears on the copy will determine the cause and solution. Horizontal lines Horizontal white lines usually indicate the ink cartridge is running out of ink or has some clogged ink nozzles. Try the following steps: 1. Some of the ink cartridge ink nozzles may be clogged with dry ink. Use the ink cartridge cleaning service to try to clear them. Follow the steps below: 1. Verify that there is plain white paper in the Input tray. 2. Press Setup. 3. Press or to select Tools and then press OK. 4. Press or to select Clean Print Cartridge and then press OK. The unit prints a test page. 5. Examine the test page. If the print quality of the page is good, stop here. If the print quality appears to be getting better, run the Clean Print Cartridge utility again 2. If the self test appears better, Increase the copy quality setting (Normal or Best) and try copying again. If the quality is still poor, continue to the next step. 3. If the quality is still poor, one or more of the cartridges may be low on ink or empty. Follow the steps below to check the ink levels. 1. Open HP Solution Center. 2. Click Settings. 3. Click Print Settings. 4. Click Printer Toolbox. 5. Click the Estimated Ink Levels tab. Figure 1: Estimated ink levels - both cartridges low NOTE: You can also open the Printer Toolbox from the Print Properties dialog box. In the Print Properties dialog box, click the Features tab and then click Printer Services button then click the Estimated Ink Levels tab. 6. Replace any ink cartridge that is low on ink. 4. If the ink levels are not low, clean the cartridge face and electrical contacts at the back of the print carriage. 1. Open the front of the unit to access the ink cartridges. 2. After the ink cartridges are at the center, unplug the power cord from the back of the unit, and remove the ink cartridges. The power cord must be removed to ensure that the unit is not damaged during the cleaning process. 3. Clean the cross-hatched area of the ink cartridge with a soft clean cloth that is slightly dampened with clean water to remove any build up. Avoid cleaning the ink cartridge nozzle plate. Cleaning this area can force foreign matter into the ink nozzles and plug them. Figure 2: Cleaning the ink cartridge 1 - Clean in the cross-hatched area only 2 - Do not touch the nozzle plate 3 - Clean the copper-colored contacts 4. With a soft lint free cloth slightly dampened with clean water, clean the copper-colored contacts on the back of the ink cartridges. 5. Allow the cartridges to dry before reinserting them. 6. Close the unit, and plug the power cord back in. 7. Print a self-test page to check the results. Follow the steps below to print a self-test page. 1. Press Setup. 2. Press or until Print Report displays and then press OK. 3. Press or until Self-Test Report displays and then press OK. The self-test report prints. 5. If the problem is not corrected by cleaning the ink cartridges, replace the ink cartridge(s). Vertical lines Vertical white lines usually indicate the scanner did not calibrate correctly. This can be caused by debris on the scanner glass or white reference pad. Try the following steps: 1. Turn off the HP all-in-one product and unplug the power cord. 2. Open the document cover to access the scanner glass. 3. Using a non abrasive glass cleaner, thoroughly clean the scanner/copier glass, and white lid backing on the inside of the top cover. CAUTION: Spray the cleaner onto the cloth. Never spray fluids directly onto the HP all-in-one product. 4. Plug in the power cord and turn on the HP all-in-one. Let me know what happens, Good Luck, Tim
