My HP Laserjet P2055dn prints out with a shadow of everything printed.


The ghosting is caused by the fuser assembly. The main user roller has a Teflon coating that keep the toner from sticking, when the coating wears off you start getting the ghost printing like you are having. You can get replacement fusers online from many sources, just do a Google search for P2055DN Fuser. They are user replaceable, only requiring a Phillips screwdriver to replace.

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

Normally ghosting is caused by a bad fuser.
Put paper in the manual feed tray(tray 1)
Print something. As the paper gets 1/2 way into the printer, open the cover..
Look at the paper. If there is no ghosting, the fuser is bad. If there is ghosting, could be a cartridge drum.
Follow these steps print a Print quality troubleshooting page to identify which print cartridge is causing the issue.
  1. Open Toolbox .
  2. Click the Help folder, and then click the Troubleshooting page.
  3. Click Print , to print the page. The page prints five bands of color, which are divided into four overlapping sections. By examining each section, you can isolate the problem to a particular print cartridge. Figure 4: Print quality troubleshooting page bandsc01417618.gif 1 - Yellow 2 - Cyan 3 - Black 4 - Magenta

My phaser 740 has print that flakes off when you print pictures with real dark areas. I assume it needs more fuser heat or less paper speed. The problem is I can' t figure out how to adjust either of these...

Recalibrate the colors. Flaking is sometimes caused by more ink/toner than can be fused to the media. There's a limit for the total amount of ink/toner. Yours may be set too high.
You'll need a copy of the Printer's User's Guide (also Downloadable from

Controlling Color Density

When colors look faded, adjust the toner color density to extend the life of the components.

Print and use the Color Reference Page 1 In the printer's front panel, scroll to Calibrate Colors,

press Menu and print the Color Reference Page. 2 Compare the Color Reference Page to the Color Density

Samples on page 39. Make a note of the value (-10 to +10) for each color that most closely matches the samples.

3 Adjust the density for each color: Enter the value noted in Step 2 in the Calibrate Colors menu, under Adjust Each Color.

? Decrease color density: Press . ? Increase color density: Press --->.

4 Reprint the Color Reference Page; check your adjustments

Ghost printing


You have a worn image drum. The drum is the part of the printer that the print image is created on before it transfers the toner to the paper. This part is coated with a very thin layer of Teflon so the toner does not stick. When it gets worn the toner starts to stick and that produces the shadow or ghost image approximately 3 inches down the page because the diameter of the drum roller is 3 inches. You will need to get the part DR-350, Office Depot has them as well as many places on the internet.

Bad drum unit poor fusing or paper type try to print paper type cardstock as type, this increases fuser temp and slows printer for better quality.

Hp laserjet 2600 ghosting

You are most likely correct. this is called fuser offsetting, to check it out, stop the paper being printed MID CYCLE open the front door just when you think the paper is behind it..., pull the paper off the transfer belt. Is the ghost there? Probably not, and if it isnt, then it is your fuser. I can lead you to a reputable supplier. You can buy QUALITY rebuilt fusers with great warranties at prices well less than new OEM.

Phaser 740 Printing Cyan only

The problem is usually caused by a faulty imaging device, specifically a bad cleaning blade.
Occasionally this error can also be caused by a sticking cleaning blade clutch.

In this case the grease that was used to lubricate the part becomes gummed up and the moving parts begin to stick and don't move freely as they are supposed to. This is especially common on these printers if they are not used heavily or have sat for long periods between uses.

Sometimes you can free up this gummed up grease by running the solenoid diagnostics several times over. You do this by turning off the printer and then powering up while holding buttons 1 and 3 on the front panel display. Button 1 is the exit button.

This will put your printer into service diagnostics mode. Page through the diagnostics menus until you come to the clutches and solenoids menu. Here you need to hit the start button, then scroll through till you see the test for the cleaning blade. Press start to run the test.

Let this test run for about an hour then hit the stop button and turn off and restart your printer.
If your printer is printing normally again then the sticky clutch is your problem and you will eventually need to remove it and clean off the old grease and relube it. I recommend a high quality lithium grease.

If your printer does not print correctly again after doing this test, then chances are that your cleaning blade on your imaging unit is bad and the imaging unit will need to be replaced. You can generally find them on ebay for a reasonable price.

This problem applies to both the phaser 560 and 740 models. The imaging units on both these printers are also interchangeable. So if you have a phaser 560 you can use an imaging device from a 740 and vice versa.

Fuser change help

is it asking you to reseat the fuser or reset the fuser?

These printers do not have any kind of reset for new consumables such as the fuser. They will be automatically detected by the printer. Though sometimes it will take several hundred pages before the proper levels are detected on the new parts.

If it is asking you to reseat the fuser then you need to open the front panel and remove the fuser. Once it is out make sure that there aren't any pieces of paper or protective plastic that are covering any of the connectors.

Once that is done, simply slide the fuser back into place and re tighten the screw that holds it in. After the fuser has been reinstalled you will need to turn the big blue knob on the fuser several turns in the direction of the arrows that are printed on the knob.

You can do this procedure either with the printer turned on or off.
