Two faint white horizontal lines


the white ghost lines are down to the charge wire within the toner cartridge being dirty, the only real way forward is to replace the toner cartridge as access to the charge chorona wire is not possible without ruining the cartridge itself

Replace cartridge on hplaserjet2300dn


Hello!
Thank you for your inquiry.
HP LaserJet 2300dn The HP LaserJet 2300dn printer is the same as the HP LaserJet 2300n printer, except that the printer comes with a built-in duplexer (for automatically printing on both sides of paper).
Here is a link to the user guide that will help help you with a lot of common problems including managing the print cartridge area on beginning on page 68. http://www.avss.ucsb.edu/download/hp2300man.pdf
If this is a new toner cartridge the installation instructions will be included inside the packaging including instructions on eco-sensitive means of disposal of old cartridge.
If this is your first time installation you will find it's very simple.
  • Turn the printer off.
  • Open the top cover.
  • If new - remove any orange tabs labeled remove 1st. If this is a replacement cartridge grab the old toner cartridge by the finger hold indentation and pull up.

CAUTION

To prevent damage to the print cartridge, do not expose it to light for

more than a few minutes.

Be careful not to touch the transfer roller (the black, rubber roller located

underneath the print cartridge). Skin oils on the roller can cause

print-quality problems.


  • Install the new print cartridge. It should slide easily down the guide slots on either side.
  • Close the top cover.

Note:

If the print cartridge is difficult to reinstall, make sure that the registration

plate has been flipped back down into position and that you have

pushed the print cartridge firmly in place.


  • Power the printer back on.

Hope this helps helps. Please keep us updated and remember to rate this answer.
Thanks for using FixYa,
TF

Our HP Laserjet P4015N is printing funny. When printing out a column of information, it will continue to print the information above it, in the white space below the column of numbers in a grey tone. I...


Hell

The "ghost print" you are getting is caused the fuser, even with 60% life left. We have seen this type of wear pattern happen if you print more on one side of the page than the other, or print darker images than standard use would be. The fuser heat roller is coated with Teflon to prevent the toner from sticking to it but when the coating gets worn down you get the ghosting like you have. You can replace just the fuser or you can get the whole maintenance kit and just keep the pickup rollers for later use. If you open the back of your printer so you can see the fuser you should be able to see the heat roller and most likely you will notice a worn area that is not the same color as the rest of the roller.

I hope this helps, if so please rate our solution.

Laserjet 4MP paper jam problem Half feeds from


I have seen this issue before and your problem is likely due to very fine paper dust on the pickup rollers. This is easy to fix and takes only a few minutes. Use a soft piece of cloth (not a paper towel), a computer cleaning towelette or anything that does not produce lint; dampen it (unless your are using a towelette) slightly with cleaning alcohol and wipe off the paper pickup roller on all sides. You should also remove the toner cartridge and vacuum out the interior of your 4MP, use care if you are not used to poking around the interior of HP printers. You will usually find both white paper dust and maybe some black toner dust. Put the cartridge and paper tray back in place, print a couple of blank sheets as a test - you should be good to go.

Printing black line down middle of page when coping


The fuser is located in the back of the printer. I think it's held in by to screws. It's about hte same size as the toner cartridge. Please visit these websites.

This is the fuser kit.

Printing Blank page


1: try another toner cartridge (or possibly pull the seal from the side of the cartridge you have just installed)

2: If it's not the cartridge causing the problem take it back - it has 1 year warranty.

Clean the static strip on the printer, details should be in the manual on how to do this. Also verify that your imaging unit and fuser are in good condition.

Every page covered in magenta and black won't print across the page


This is caused by toner contamination in the laser scanner unit, it is quite a complex job removing and cleaning the laser scanner. I would suggest you contact HP regarding the repair.
