Replace photoconductor unit setting error

The printer has no way of knnowing that you have changed the Photoconductor Unit, unless you tell it (as there is not chip on the Photoconductor).

The Photconductor reset procedure is as follows.

Dell 1700
RESETTING DRUM PAGE COUNTER

1) Leave the power on, insert toner cartridge, and leave door open
2) Press the cancel button and hold till the leds flash
3) Release cancel button and close toner cartridge door

Hi

Try taking out all toners and reinstall them. Turn on unit, without Photoconductor, wait till you get error install photoconductor. Insert photoconductor and try printing again.

Hope this helps

You will need to get the photoconductor unit replaced.

The printer will display a Resetting PC Count Value message and go back to the previous screen. 3 Press once. 4
Press or on the operator panel until you see Exit Config Menu. Press once. Selecting this will cause the printer to reboot.
If the counter has been reset correctly, the printer should return to a Ready prompt. 5
If this does not clear the PC Life Warning or Replace Photoconductor message, power off the printer and attempt this entire procedure again. If the error remains after two attempts, confirm that:

• The correct photoconductor unit is installed. The part number on the photoconductor unit should be E250X22G. If it is not, install the correct photoconductor unit into the printer.
  
  
• The photoconductor unit has not been refurbished by a third party or is not damaged in any way. If the photoconductor unit was refurbished by a third party or appears to be damaged, try replacing it again before seeking service on the printer.

To reset the photoconductor page count:

1. Turn off the printer.
   
2. While the printer is off, press and hold the Select () and Return () buttons on the operator panel.
   
   
   
   
3. While keeping both buttons held down, turn the printer back on. Keep holding down both buttons until the printer screen displays Performing Self Test or CONFIG MENU.
   
4. Release the buttons when you see either of these messages.
   
5. If Reset PC Cnt does not then appear on the screen, press the left or right menu button until it does.
   
   
   
6. Press the Select button once. The message Resetting PC Cnt Value should briefly appear on the screen, indicating that the photoconductor page count has been reset.
   
7. When the display shows CONFIG MENU again, power off the printer.
   
8. Wait five or more seconds and then power the printer back on. NOTE: Do not hold any buttons down when powering on the printer during this step.
   
   The photoconductor page count should now be reset. At this point, it is recommended that you print a menu settings page to confirm this. Do the following:
   
1. With the printer at the Ready status, press the left or right Menu button until UTILITIES MENU appears on the screen.
   
2. With UTILITIES MENU on the screen, press the Select button once. A new menu should appear.
   
3. If Print Menus is not displayed on the second line of the screen, press the left or right menu button until Print Menus appears.
   
4. Press the Select button once. The message Printing Menu Settings should appear on the screen and the printer will print out one to three pages of printer settings.
   
5. Look for a heading labeled Cartridge Information on one of the menu settings pages.
   
6. Under Cartridge Information, look for the word Photoconductor. Confirm that the level of the photoconductor says OK or is close to 100%.
   
7. If the photoconductor is still reading low, try printing 10 - 20 more pages.
   
8. Print the menu settings page(s) once more. Confirm that the photoconductor level is now at OK or close to 100%.
   
9. If the photoconductor continues to give a low reading, repeat this entire procedure again from the beginning to reset the counter once more.
   
10. If the photoconductor reading is still low after two attempts to reset the counter, the printer may require service.

Turn printer off and remove photoconductor unit, close covers and turn printer back on without photoconductor, error will appear that you need to install photoconductor, install photoconductor and wait til it calibrates, if same error appears photoconductor is a consumable part you will have to replace it then.

Pls dnt 4get to rate solution. TY
