I would be willing to be it's one of two things.

Most common is a jammed gear on the imaging units. Remove all imaging units CMKY. The turn on machine. If the noise is gone, start replacing imaging unit one at a time tile noise reappears. Replace defective imaging unit.

If that doesn't work remove the accumulator belt from the right side of the machine and then turn machine on, see if noise is gone. If so replace accumulator belt.

Xerox 6360dn, Tray 2 makes loud grinding noise when printing. Tray 1 is as quiet as a mouse. Replaced tray 2 with a known good tray and it still makes grinding noise.


In my experience, it was the registration roller causing the grinding noise. See http://my.brainshark.com/Phaser-6300-6350-6360-Grinding-Noise-795590408 for troubleshooting video.

Xerox phaser 7700 having problems printing transparencies and accumulator belt problems


Hi xander4265:
I
Streaks in direction of paper travel
There are dark lines running along
the page in the direction of paper
travel from the leading edge to the
trailing edge (B-size print shown).
The printer displays no error code.
Note A-size prints are processed
through the printer with the short
edge of the print parallel to the
direction of the paper path --
making horizontal print artifacts
parallel to the shot edge of the
print.
B-size prints are processed
through the printer with the long
edge of the print parallel to the
paper path -- making horizontal
artifacts parallel to the long axis
of the print.
1. Check the end of life for each of
the consumables by printing the
supplies usage page. From the front panel’s Printable Pages Menu, select
Print Supplies Page.
2. Run the solid fill test pages; From the front panel’s Printable Pages Menu,
select Service Pages, then select Print Solid Fill Pages. If the missing bands
only occur in a single primary color, replace the print cartridge of the affected
color.
3. Swap print cartridges and run another test print.
Note Under some circumstances, streaking may occur in the margin of
SRA3-size paper. This is due to the edges of the paper extending
beyond the end of the imaging components. print-quality in the
margins of SRA3 paper is not guaranteed.
4. Inspect the Accumulator Belt cleaner; replace the cleaner, if necessary.
5. Run the Remove Print Smears routine. From the front panel’s Support Menu,
select Improve Print-Quality?, then select Remove Print Smears.
6. Replace the Developer Housing Assembly (RRP 27, on page 7-171).
7. Remove the print cartridge and (with a flashlight) check for debris along the
edge of the developer housing.

hope that this will help you.

The answer can be found here: http://office.support.xerox.com/SRVS/cgi-bin/webcgi.cgi
You must manually reset the Belt Cleaner life after replacing the belt cleaner.

Resetting Belt Cleaner Life
  • Resetting the belt cleaner life is to be performed only if the Belt Cleaner Assembly was defective and or the assembly is replaced before an end of life or near end of life message. Not to extend the life of the assembly. Doing so may cause premature failure of other internal printer components.

  • The printer will prompt the user to reset the life counts if the assembly is replaced after receiving a Replace Belt Cleaner Assembly or Replace Belt Cleaner Assembly Soon message.
note_image33x30.gif    Note: If the main Menu does not appear on the front panel screen and only Replace Belt Cleaner Assembly is displayed, there may be a print job that is either processing or currently printing. Try the following steps to clear the print jobs and reset the Belt Cleaner life:
  1. Press the cancel button several times to flush processing jobs from the printer.

  2. If you do not receive access to the front panel menu by doing this, then power off the printer and disconnect Ethernet, parallel or USB cable from the printer.

  3. Turn the printer back on, and while it is powering up, immediately start pushing the cancel key repeatedly until you receive access to the front panel menu.

  4. If the printer menu appears on the front panel screen, follow the instructions below to reset the Belt Cleaner life if the printer didn't prompt you to reset it:


  1. With Menus highlighted press OK.

  2. Press the Down Arrow and scroll to Supplies Info Menu.

  3. Press OK.

  4. Press the Down Arrow and scroll to Exit at the bottom of the menu tree.

  5. Now scroll up to Reset Belt Cleaner Life
  6. .
  7. Press OK.

  8. Reset Belt Cleaner Life NOW is displayed.

  9. Press OK to reset the belt cleaner life.
