Question about Xerox Phaser 8400 Laser Printer

1 Answer

I have a xerox 8400 and it just keeps jamming. actually i noticed the blue was not prinitng..and was actually pinkish...i thought a ink block was put in wrong so i was making a lot of solid blue copies to run it through and did a maintance/cleaning and the jam started. no error codes...just clear the paper then jams right up again. it does make a lot of noises but i think it always was a noisey printer...and made weird sounds. i wanted to open the sides and see if there was something obviously wrong or broken but not sure how to do that with out breaking it!! any help please

    from the tray the paper is stopping in the front cover section...if you open the front cover the paper is always in the same place...partly still in the lower tray.

    the paper is not damaged..untill i pull it acordion folds.

    no error messages..just that it is jammed.

    asking for a cleaning sheet of paper....

    It will not accept the sheet of paper from the front loader...only paper from the tray.

    any ideas?

Where does it jam? Is it making an "accordion fold"just before it enters the front rollers? Does it pick up a second sheet from the tray in the process?
Does it print OK from the manual feed tray?
If so, there might be a sensor worn out at paper entry, near the entry rollers and the plastic curved flap in the front. Once had this problem, the sensor's plastic "tongue" was half it's usual size, worn out by the paper abrasion alone.

How do you fix error "07,010.43:14085" on the Xerox Phaser 8400

The error is normally caused by the print head wiper being stuck to the print head or the print head pivot block being contaminated with spill over ink.
To clean the block you remove the left side cover. There is a stainless steel block about 1 inch by 1 inch about midway back on the lower frame. It would most likely have a lot of yellow ink in it.
If the wiper blade is tacked to the print head, you would remove the right and left cover. then remove the ink loader. ( where you place the ink sticks.). Once you remove the ink loader you are in the print head drum area and would gently detack the blade from the print head, then run the eliminate light stripes in the troubleshooting menu.

Xerox Phaser 8400: Our printer keeps jamming. Some of the ink is staying on the right edge of the drum and it seems as the paper goes through the printer it gets stuck on that ink. We use only Xerox ink...

There are no less than 5 places on this model where you might clear a paper jam. Is it possible you still have a small bit of paper stuck somewhere?

Ink not being removed from metal drum, causing jam

Normally indicates that the mintenance kit is drying out and not properly lubricating the drum.
Or non xerox ink sticks have been known to cause that.

Xerox phaser 8400 error

That is a print head tilt error. Either the print head pivot block is contaminated with ink or the wiper blade is tacked to the print head.
Let me know if you want to try to resolve it yourself, I will send you directions.

Xerox Phaser 8400 turns on then error 07,010.43:126070

Yeah it is a hardware issue. The code you are getting relates to the print head tilt and/or side to side movement.
One of 2 things occur to cause that code, these 2 things cause that code about 90 percent of the time.
1. When you remove the ( looking from the front of the machine as refrence) left cover, about 1/2 of the way back, on the bottom portion of the frame, you will see a 1 inch x 1 inch steel pivot block. Often times runoff from the excess tray or seepage down the print head will cause ink to build up in that block. That will not allow the print head to pivot back and forth properly causing that code. There is a spring over that block you need to clip aside to remove the block. It may be very sticky and a little difficult to remove. Channel locking pliers will normally allow you to remove it with some effort. I suggest putting the block in some pretty hot water . It makes the ink softer when hot and easier to remove.
You want to also picko ut all the excess ink in that are that you can to keep the block from gumming up again. Removing the print head is the best way to clean it, but that is pretty challenging if you donr know hte printer.
Now issue 2, is the print head wiper tacking to the print head. If the machine is not powered down properly or is unplug, or a power failure can cause this blade to be in the wrong position and stick to the print head. To access that, you want to remove the right and left covers, and also the ink loader, ( Where you load the ink sticks). It is held in by tabs and 2 plugs. Once you remove that ink loader you have access to the print head drum area. Look between the print head and drum for a pinkish colored blade, Gently detack it from the print head and run the cleaning cycle on the printer when reassambled.
The print wiper clutch could be going back causing the blade ot tack, but not as likely.
That code is definatly an issue with print head movement, and most of the time these 2 issues will resolve the problem.
Let me know, There are a couplf of other weird things that can cause this, But I doubt they are an issue.

Ink gets carried over to subsequent sheets

More than likely your maintenance kit roller has been impacted with ink and is not applying enough lubricant to the drum. You can replace the maintenance kit and run cleaning procedures a couple of times to allow it to clean up.
Now the other issue is if you are using a third party ink stick. By that I mean non xerox brand ink sticks. I have seen those cause that problem more often than not.
Pull out the maintenance kit and see if the large roller, which should be a off white, is black.
Exacly what is happening is your maintenance kit puts a very thin film of silicon oil on the drum so that the ink does not adhere to the drum more than normal. When that roller becomes blackened, it isn't very effective and you get some of that residual imaging.

I have a phaser 8400 banding problem. Actually reverse banding. It is ligher ink vertically along left margin and an inch from right margin. Is this a drum problem? It notes I am low on ink and have only...

nope its not a drum problem, That drum never goes bad. You are having a problem with some blocked jets in the print head.
You can scroll through your menu to troubleshooting and there are cleaning modes to eliminate light stripes and to eliminate smears.
Run the eliminate light stripes maybe 2 or 3 times. If that doesn't work, then try the jet substitution mode.
That is better described at, click support, then enter phaser 8400 in the search box, click support again and then enter
"jet" in that search and follow the directions.
If those do not work then your print head is most likely bad. Thats more likely if you have used non xerox ink sticks.Being low on ink should only give you a message that its low.

Phaser 8400

The 8400 has a known issue with the plastic that was used for the tilt mechanism on the oiling roller. If you look inside where the cartridge is removed you should see a crack that opens when pressure is applied. The high heat causes this unit to crack. You need that part. Or some good super glue. I have fixed 3 of my 8400's with this same issue.

Good Luck
