I;m not sure what your question is, but if your getting a drum error, it could be one of 2 things.

1. you need to clean the wires on the drum, there is a purple tab that slides back and forth that cleans wires.

2. you need to replace the drum. take the toner cartridge out of the unit, separate it from the drum, replace the drum, re-attach toner cartridge to the drum, and re-insert the toner back into the printer.

thanks

    by cleaning the drum with alcohol, you ruined the drum.
    if you did not do option #1, then you will need to do option #2

    i dont know how well the drum will work with the way you cleaned it, thats not supposed to happen.

Error code 07.009.42 what should I do?


07,009.42 Error indicates that the printhead was unable to tilt normally on its axis.

This is most likely caused by a cracked drum maintenance camshaft. The drum maintenance camshaft is driven by the process drive motor on the right side of the printer. It raises and lowers the maintenance kit against the drum to oil and clean the drum. The camshaft has 2 lobes on it. These lobes crack over time and cause several different error conditions. The camshaft part # 401100380 is only about US$20 from Xerox but can be very difficult to replace. Also look at the pivot plate assembly. Slide out the drum maintenance kit. If you look inside the cavity the plate that the maintenance kit sits on is called the pivot plate. If the drum maintenance pivot plate is white plastic it should also be replaced with the new style black plastic plate. This requires removing the process drive gears assembly. Note that reinstalling the assembly requires the gears to be accurately timed. This repair should only be performed by a qualified technician.

XEROX PHASER 8550 PRINTS ONE PAGE AND JAMS THE SECOND - DID TESTS AND PAPER PATH TRAIL EDGE AND PAPER DRIVE POWER BOTH FAIL, CAN YOU TELL ME WHAT PART IT MIGHT NEED...THX


Is the Drum unit clean?
Often the Drum Maintenance kit can get dirty, and not clean the Drum properly, which can lead to jams.
Also, the drive cam for the Drum Maintenance kit can fail. This means not enough cleaning pressure is applied to the Drum unit, and it can't clean it properly, causing jams.

good luck

Sharp AR-M160 Maintenance light and developer replacement light have come on together. Where do I get developer from?


It's not developer light.
It is drum unit light and maintenance.
You have to replace the Drum, Blade and Developer.
After changing them you have to reset the maintenance, drum,developer counter.
This procedure must be made by a copier tech.

But if you still want only the developer the code is AR-202D

Hallo


07,009.42 indicates that the printhead was unable to tilt normally on its axis.

You probably have a cracked drum maintenance camshaft. If the drum maintenance pivot plate is white plastic it should be replaced as well with the new style, which is black plastic. This repair requires removing the process drive gears assembly and reinstalling it requires the gears to be timed. This repair should be performed by a qualified technician familiar with these machines.

The camshaft part # 401100380 is only about $17 from xerox but can be tricky to replace if you're not mechanically inclined. The other thing to look at is the pivot plate assembly. Slide out the drum maintenance kit. If you look inside the cavity the plate that the maintenance kit sits on is called the pivot plate. If it's white it will also need to be replaced with a black one.

8550DP Maintenance Kit


First of all make sure it is the right kit. The part numbers for teh 8550 and 2424 are very close, one ends in 675 the other in 657, so they have been known to be mixed up.
then here is the documentation..

Problem:
The machine displays the Replace Maintenance Kit after the Maintenance Kit has been replaced.
Cause:
There may two causes for this issue.
  1. The machine does not recognize that the Maintenance Kit was removed. This would likely be caused by a defective Drum Maintenance Pivot Plate.
  2. The machine corrupts the CRUM on the new Maintenance Kit. This may be caused by a defective Drum Maintenance Pivot Plate or IO Board.
Solution: thumbsup.gif Fixed! thumbsdn.gif Did not fix.
  1. While the Replace Maintenance Kit message is displayed, remove the Maintenance Kit. If the displayed message does not change to "Maintenance Kit Missing," replace the Drum Maintenance Pivot Plate and install a new Maintenance Kit.
  2. While the Replace Maintenance Kit message is displayed, remove the Maintenance Kit. If the displayed message changes to "Maintenance Kit Missing," replace the IO Board and then install a different NEW Maintenance Kit. If the problem persists, replace the Drum Maintenance Pivot Plate and install a different NEW Maintenance Kit.

Gapped incomplete printing of text and pictures


Try this:
1. drum refreshing- set A3,or A4 paper in the multipurpose tray.(bypass) press the * (asterisk) key
on the control panel. Then select drum refreshing.Select "ON".
2. Check the Drum Cleaning blade-clean it,
Drum can be cleaned with alcolhol,if copy quality is bad after that perform several drum refresh procedures.
3.Time for maintenance is just info for customer that machine has declared maintenance interval.
Customer must check Warranty terms and conditions.
resseting time for maintenance: enter 10871087,then select U251, press start.To clear,press clear key(yellow button)
and start.After that,press stop key twice,and enter 001 and start.
4. Also I suggest to clean grid on main corona.
