Tektronics phaser 850 - media jam

Sounds to me like you need to replace the fuser.
The rolls have been experiencing some problems.

Best thing to do is just brush most of it out with an unused paintbrush. You can simply vacuum the rest out with the hose attachment. Hope this helps :)

Hi,

This means the Yellow ink sticks are jammed in the machine, open up the top of the machine and check if the sticks can slide freely up and down and remove any broken sticks.

If I remember correctly, disconnect the print cable, then reboot the machine.
I saw that problem once and its been a while, but I do believe thats how I finally got it to stop.
Then clear out the print queue.

I posted a problem with the phaser 860 paper jam. I found 2 broken sensor flags and am ordering the parts.

The fuser exit sensor had an updated version for that model (old model has a "bounce" problem). Xerox gives a 1 year warranty..I would get them out to fix it pronto !

It is also helpful to have the error code. Press the i button while the printer has the jam message on the front panel. Use the fault code to locate where the jam actually is. (This will help the technician greatly ! )

The preheat entry sensor assembly probably has broken sensor arms, and will need replaced.

Problem:

The Printer's Front Panel Displays Jam At Top Cover; Open Top Cover To Clear (A7)

Cause:

Media is jammed in the fuser exit area.

Solution: Fixed! Did not fix. TRY FIRST (Solutions without parts):
1. Unsupported media. - Load supported media and set the media type correctly. 2. Dirty exit rollers. - clean the exit rollers. Paper catching on the duplex guide assembly. - Remove and reinstall the duplex guide assembly. Fuser not fully seated. - Reseat fuser







REPAIR/INSPECT/PREVENT PROCEDURE:
1. Clean feed rollers and exit rollers only when dust or
debris is visible.
2. Clean the LED assemblies.
3. Check version of print engine and image processor
firmware; as appropriate.
4. Check cleanliness of interior and exterior of printer,
including fans; if necessary, clean (dust or vacuum) these
areas.
5. Review proper operation of printer using a customer
file, if possible.
6. Review with customer all work that was performed; also
discuss how to properly care for their printer.

printers have sensors that tell the main board where the paper is, if a sensor is stuck or broken it will say jam, the question is where "A" is, look in the manual and see if you can find it, it will be either an optical or moving plastic.


hope this helps
good luck

There is a flag sensor on the registration assembly that is possibly broken.
