If its displaying the word xerox and a still red light,this means that the power is on and the processor board noticed but no further commands can go on since there is no Software.
in shord HARD DISK is missing.

My Xerox 7700 will not get past the startup screen. A red light flashes on the printer, then a clicking noise (like an unbalanced fan) starts at the back of the printer. Any suggestions would be...


Remove the back cover maybe a fan is broken or is dying out. There is a tutorial for the 7750 but they are almost exactly the same. So follow the instuctions up to removing the back cover and then turn on the printer (caution don't touch any electrical boards or any board). Then you will be able to indentify exactly which fan it's bad or it could be a gear you will be able to where the clicking noise is coming from.
Hope this tutorial helps.

Phaser 7700 Accumulator Belt Replaced, upon startup there is an error


POSSIBILITIES

Problem:
1st BTR Contact Failure or 1st BTR Retract Failure Message is displayed after replacing the Accumulator Belt Cause:
A Phaser 7700 Accumulator Belt was installed in a Phaser 7750. The Phaser 7700 Accumulator Belt does not have retractable 1st Bias Transfer Rollers; so these errors will be reported if one is installed in a Phaser 7750 printer. Solution: thumbsup.gif Fixed! thumbsdn.gif Did not fix. Remove the Phaser 7700 Accumulator Belt and install a Phaser 7750 Accumulator Belt. TRY FIRST (Solutions without parts):
1. Check that all shipping restraits have been removed.



TROUBLESHOOTING TIPS AND HINTS:
1. Test the 1st BTR motor in diagnostics to verify proper operation. 2. Test the 1st BTR sensor in diagnostics, then run the 1st BTR motor test and recheck the 1st BTR sensor. Sensor state should alternate between L and H. The sensor is part of the accumulator belt.

PARTS:Parts are listed in the order of highest probability for repair.
NUMBER QTY DESCRIPTION
116177400 1 *KIT IBT - UNIT

1. Clean feed rollers, exit rollers and guides; replace if
necessary.
2. Clean feed rollers and exit rollers only when dust or
debris is visible.
3. Remove and clean all paper trays.
4. Clean the Laser Scanner Unit window.
5. Inspect the image density sensors; clean if necessary.
6. Inspect the accumulator belt home sensor; clean if
necessary.
7. Inspect the fuser assembly; clean if necessary.
8. Print the Error Log, diagnose and repair any problems as
indicated.
9. Print the Usage Profile, diagnose and repair any
problems as indicated.
10. Check version of all installed firmware; as

Xerox 7700 won't go past warm up


The fuser is a good place to start. If it is not hot you could try another fuser. You'll feel the heat well before you actually touch the fuser if it is working.
Do not swap fusers with another printer. These fusers have a life setting and when they are put into another printer it messes it up, leaving you with a fuser registering less than 10% life left.
An additional possibility is the the fuser may not be getting the power it needs. There are two boards that control power distribution if I remember correctly, T1 and T3, but I am not entirely sure which one handles power going to the fuser. In this case it would probably be best to get a repairman in. The 7700 is not particularly easy to work on, depending on the issue, but an experienced technician with a repair manual should be able to handle it easily.
