Tektronix Phaser 840 error

Xerox at

offers four solutions. Two of the solutions say to call for service, the other two are listed below.

Phaser 840/850 Printers: Power cycle the printer
Solution Details
Turn the printer off. Wait until there are no more noises coming from the printer; in some cases this may take several minutes. Remove the power cord for at least 30 seconds.
Plug the power cord back in and then turn the printer on.
Phaser 840/850 Printers: Unlocking the Maintenance Drawer
Solution Details
The printer locks the Maintenance Drawer as a safety measure to prevent access to hot ink. The printer will automatically unlock the Maintenance Drawer when it is safe. Normally this takes about 2 minutes. Close the front cover and wait 2 minutes. Then try removing the Maintenance Drawer.
If the Maintenance Drawer remains locked, follow the steps below:
1. Close all the printer doors. The drawer cannot be unlocked if any door is open.
2. Turn offthe power switch on the back of the printer. Depending on the state the printer is in, this can take up to 2 minutes.
3. Once the printer has powered off completely, the Maintenance Drawer should be unlocked.
If the Maintenance Drawer is still locked, the printer may need to reinitialize. Follow the steps below:
1. Close all the printer doors. The drawer cannot be unlocked if any door is open.
2. Turn on the power switch.
3. Wait for the printer to display one of the following messages:
o Maintenance Drawer A is missing
o Warming up
4. Turn off the power switch.
5. Once the printer has powered off completely, the Maintenance Drawer should be unlocked.
If the drawer is still locked, repeat the previous steps one more time.
If the drawer is still locked after three power down sequences, the printer requires service.

Boy, I remember the Tektronix help page being much better than this Xerox one. The search on it is broken! You have to Search, have the page crash, then Refresh (and repost the data) just to get it to work! Poor Tektronix! I had the Phaser 740 at two different jobs. Good, sturdy printer; a little slow, though.
Anyway, I finally got through on tech support and on this page:
http://www.officeprinting.xerox.com/infoSMART/cgi-bin/webisapi.dll/,/?Session=1310725,U=1,ST=90,N=0024,K=14474,SXI=6,Case=obj(20429)
(please remove any spaces)

I found this statement:

Document ID#: 20429

Symptom
The Printer's Front Panel Displays Printer Error - Contact service; report fault 07,004.46

Possible solution(s)

Please try the following solutions to solve your problem
Phaser 840/850 Printers: Power cycle the printer. (this link tells you to hit the power button. A whole page just for that!!!)

Phaser 840/850 Printers: Unlocking the Maintenance Drawer. (to do this complicated procedure, turn the machine off for 30 sec and it will unlock. If that don't work, turn it on, then off again. If it still doesn't work, call for service. I am not kidding! These are the steps!!!)

Turn the Printer Off and Call for Service. (yep, a pageon calling them.)

Phaser 840 Printer: Service is required. (another page on calling for help.)

So, here is the deal. If power cycling doesn't fix it (and it won't) call and get it looked at.

I remember I had to call for service 3 times in 2 1/2 years on the Phaser 740. This machine is not very nice to the average Administrator. Basically, if it every reports anything wrong other than out of toner (or the dreaded fuse roller! I hated that thing!!!!), call your service tech and have him/her fix it.

Look at these things:

The memory in this printer might be faulty or installed incorrectly. If it is equipped with additional memory chips, try removing the extra memory to see if it works without it. If so, you may want to replace it. (Or work without it.)

The host system can be connected to the printer only by a parallel cable, so make sure a serial cable is not being used. And it must be a bidirectional parallel cable.
