Phaser 8400 blurred print

Hi all,
Yesterday my printer was printing fine. Today everything is blurred. I'm need to do a big post card and catalog run and live in a small town. The maintenance kit hasn't been replaced in a long time - could it be simply that? I can tell from the info pages as they are too blurred to read :-)
I would sure appreciate any help you can give. Xerox support is not available on the weekends anymore, so thank heaven for you all!

    Thank you SOOO much! Your solution worked perfectly. The print is actually sharper than ever now. We have a big print job to do this weekend and it wouldn't have been possible without your answer.

If it is blurred, the problem is the drum motor encoder. It picks up the silicon lubricant from the maintenance kit, and once its gets contaminated it causes the drum to run the wrong speed.
What you have to do is remove the right cover, looking from the front.
Then locate the drum. Its about mid way back on the machine. The encoder is in that area.
If you go to Xerox.com, there is a parts list and diagrams located under drivers and documentation.
Look up the parts list and the Drum encoder to locate it. It is not real hard to find, or remove and clean. What you want to clean it with is alcohol. No no, Not vodka..... use a strong rubbing alcohol to break down the silicon and clean the encoder, then put it back on the machine.
It may need replaced, but the majority of the time, cleaning the encoder resolves the problem.
You may just want to write down the part number when you locate it, just in case you would have to order one. But I really believe cleaning it will resolve your problem. It does fix the blurrs about 80 percent of the time.

Can you please tell me how to print double sided? Thanks


Xerox Phaser 8400 does not support double sided prints. You have to have a Duplex Unit for Phaser 8400 part number 097S03177 to be able to print double sided. If you have the duplex unit, on the Print dialog box just click Preferences and under 2-Sided Printing select 2-Sided Print then Apply.

How to set up printer to print double sided. Printer Xerox Phaser 8400


First look at your printer identification.

You can see it in either the display or on the startup or configuration pages.

It must have a "D" in the name for you to be able to do automatic duplexing. i.e. 8400DN or 8400DX . Then you can scroll to printer setup
and select defaults, and then turn on the duplex, or double sided printing.

If yours does not have a "D" i.e. 8400, 8400N then you would need a new sim card to enable the duplex option.

My print jobs keep coming out with smears in certain spots and now the entire print job is blurred. I've cleaned it several times. How do I correct that myself?


If the entire page is blurred, it is probably a dying wave amp board. Time to start shopping because the repair bill is more than a new 8560.

Phaser 8400 print management


Yes you can. If it is just you printing you can go into printing preference. Then TekColor and click the black and white option. It will force everything printed to be B&W. You can only limit others to B&W if it is hooked up via ethernet with a IP address. Type in the IP address in your internet explorer as you would a webpage. Go to the properties tab then Printing Security Settings and type in a Color Permission pin. Then if you need to give someone access to printing color in the printers preferences on the layout tab click the advanced button, Under printer features there is a color access area that you can type in the pin to print color. If one color runs out it will not continue to print. It can cause very expensive damage to your printer if it trys to print with no ink in the printhead. So to be safe it stops the machine from printing.
Hope this helps.

An 8400 prints with a USB or a cat 5 cable ( ethernet, regular internet cable). You can not print to a Phaser 8400 with a parallel cable. I really can't figure why you would get that message.You enter the network settgings and set an IP address, then configure your print driver to match.
There is no parallel port on a 8400.

Hi, we have a big problem


I would guess Orange = light red (magenta) indicating a problem with a clogged ink nozzels on the print head.
So might need an engineer if the cleaning option (on the printer menu) can't fix it.
Cheers

The first obvious question is, "Does it have blue ink/wax?" Is it displaying any errors? Have you tried the Xerox support site? They have a fantastic utility that can connect to your printer and diagnose many problems. Here's the URL for the utility: http://www.phasersmart.com/ They also have a wealth of information in their knowledge base. Here's the URL for the support page for the Phaser 8400: http://www.office.xerox.com/printers/color-printers/phaser-8400/sprt-enus.html Did anything happen before the blue quit printing? Have you tried running a cleaning cycle?
