My Xerox Phaser 7400 refuses to recognize the new black imaging unit.
It told me my imaging unit was near the end of its life so I replaced it with a new one. But it still showed the message it was near the end of its life and it did not update the installation date.
I have replaced it, cleaned the entire inside of the machine, replaced toner etc. And still it said black imaging unit is past end of life. Since the machine was still working, I just ignored it but now it has clearly decided the imaging unit is really finished and the machine has stopped working. I *know* the imaging unit is not finished as it is a new one.
In the end, I actually managed to solve it myself. I went into the Trouble Shooting and then Services and then pressing the up & down buttons at the same time, a secret menu (called Secret menu :-) pops up and that allows you to force a reset of the supplies counters. So I reset the imaging unit to 0 pages and that did it.
Weird machine.

I have a Phaser 7400 with the same problem. I followed dutchcloggie's instructions and was able to solve the problem. However, the menus on my 7400 were slightly different: Troubleshooting - Service Tools - Up&Down Buttons - (Hidden Service) - Run Service Diagnostics - (Print Service Menu Map Appears) - NVRAM Access - CRU Counter Resets - Reset Toner Counts (Optional) - Reset IU Counts - (Reset As Needed/Will Be Returned to CRU Counter Reset/When Done Hit Back Button) - NVRAM Reset - (Confirm) - (NVRAM Resets/Printer Hangs Upon Exiting Diagnostics) - Power Off/On - (Cartridge Should Now be Recognized)
Thank you David HG (and dutchcloggie) by Crazy Eddie (8/1/11 7:17 AM) reply
We have just gotten a phaser7400 with low usage and when we send a file from our computer that is suppose to be totally black and also put black in the printer dialog box it prints part of the form in black and some of it in color of dark brown! What are we doing wrong! We send the same file to our Xerox 7345 and indicate print black it does so! Any body know what we are doing wrong! How do we get the phaser to print the image all black?

We have a phaser 7400 that prints a black file in black and dark bown when it is suppose to printing the whole form in black! What do we have to do to get the file to print all black! We indicate black only in the printer dialog box when it is sent to the phaser7400!How do we get it to print all black! Is it the file or something in the printer! It prints fine with other files!
