SOURCE: Tranfer Unit

  1. Open the Top Cover on the printer.

    CAUTION: Do not leave the Top Cover open for more than 10 minutes without covering the Imaging Units as damage could result. Use the dark bag that came with the Imaging Unit or opaque paper as a cover.

  2. Remove all four Imaging Units (which includes removing the Toner (Dry Ink) Cartridges attached to the Imaging Units). To avoid Toner spills, hold the Imaging Unit in an upright position.

    CAUTION: Do not use warm water or cleaning solvents to remove Toner (Dry Ink) from your skin or clothing. This will set the Toner and make it difficult to remove. If any Toner gets on your skin or clothing, use a brush to remove the Toner, blow it off, or wash it off with cold water and mild soap. Do not attempt to use a standard shop vacuum or home vacuum to clean Toner spills in or near the machine. Shop and home vacuums are not equipped with correct filtration and will contaminate your environment.

  3. Raise the two gold colored latches (front and rear of printer) to unlock the Transfer Unit.
  4. Grasp both gold colored handles (center and right) to lift the Transfer Unit out of printer.

To install a new Transfer Unit:
  1. Remove the new Transfer Unit from its packaging or shipping materials.
  2. Grasp the two handles on the new Transfer Unit and place the left end into the frame alignment sockets.

  3. Lower the right end of the Transfer Unit down until it lays flat in the printer.

  4. Press down on both latches to secure the Transfer Unit into position.
  5. Make sure the Transfer Unit is latched into position. Lift up on the right handle to see if the Transfer Unit lifts up. If the unit does not lift it is latched correctly.
  6. Re-install the Imaging Units and Toner (Dry Ink) Cartridges.
  7. Lower the Top Cover.
  8. Dispose of the old Transfer Unit as normal office

That is normally caused by a bad developer housing.

SOURCE: Xerox Phaser 7300 color misregistration

Apparently, turning the unit off for 30 seconds, then back on will force the Phaser 7300 to do a color alignment procedure (according to Xerox support).

Then, if the problem persists, you are instructed to follow a very detailed troubleshooting procedure which I will leave with you in the following link:

Why is my Phaser 7400 printing a solid pink page? The Transfer unit is half pink. Is this why?


This may be a high voltage problem.
Am not familiar with this machine but is a generic fault.
Ensure contacts to drum/cartridge are clean.
Next
If possible, unplug machine, open up and ensure all high voltage connections are good.
Good luck.

Xerox phaser 7400 giving error - replace imaging unit- what solution now?


Did it specify a color you should replace? The machine has 4 image units (CMYK) each with a different part#. Replacing them is easy, no tools required. Open the top door, lift out the entire image unit, move the toner over to the new unit, and lower the image unit. Here are the part #'s for the 7400 for each color. Iteminc.com has these online.
C - 108R00647
M - 108R00648
Y - 108R00649
K - 108R00650
Good luck, hope this helps. Thanks for using FixYa!

Faint horizontal dark line about 2 1/8 inches down from the top


Hi,

You can easily fix this yourself, one of the quickest ways to fix it is to print 10 doublesided blank pages and it will clean the inside of the machine for you and the line will vanish.

For further print quality problems on this machine follow these instructions to troubleshoot.

When troubleshooting image quality problems, it is important to understand the situations in which the problem occurs.

Print a copy of the color test pages to determine whether the problem is in one color or more than one color.
  1. Press the [Up] or [Down] arrow button on the Control Panel to select [Troubleshooting] on the Display Screen, and then press the [OK] button.
  2. Press the [Up] or [Down] arrow button to select [Print Quality Problems], and then press the [OK] button.
  3. Press the [Up] or [Down] arrow button to select [Color Test Pages], and then press the [OK] button to print the test pages. If the problem occurs with one color on the test pages, perform the solutions for this problem. If the problem occurs in more than one color on the test pages, restart your search and select a case for the image quality problem occurring through all colors.

Fan Failure Error 54


1 of 2 things.
You need to clean or replace the fan.
You have to remove the back, right side and top cover to access that fan.It is near the back just behind the fuser module.
It could also be the low voltage power supply fan. Most likely the fuser fan.
Once you remove the fan, there is a label on it, remove the label, There is a rubber plug behind the label, remove the plug and drip some lubricant into the fan. Reassembly and it should be ok.
I would recommend replacing the defective fan though.
Here is a very reliable part source.
https://www.partsdrop.com/store/

If you call ask for Britt and specify the model number and that you need a fuser fan and probably order a Power supply fan, Neither are very expensive.
Have both on hand to be 100 percent sure the problem is resolved, But its a 90 percent fuser fan failure code. It operated in a heated area and can dry out faster.
