Changed drum July 2010, display panel continued to say change drum, but was printing fine until now the printer stops printing in the middle of a report, I have to open and shut the "hood" several times before my entire report is printed. I am really at a loss of what to do. Thanks for any help you can supply.

It's just holding the button on the front while switching on the printer and let the lightsequence run till it stops. An advertisepage will roll out and all runs well.

This message would continue to appear if the drum counter was not reset when you replaced the drum. To reset the drum counter, follow the instructions listed below.

1. Open the front cover.
2. Press the Options key on the control panel.
   The display will show "REPLACE DRUM - 1.YES 2.NO".
3. Press 1 to reset the drum count.
4. Close the front cover.

Brother strongly recommends that customers use only genuine Brother drum units and/or toner cartridges. Each Brother laser printer is designed to work at pre-set temperatures that are matched exactly to each of our individual toner formulations. Each individual component is designed to work with the other to ensure quality and reliability. Using non-Brother supplies may affect the hardware performance, print quality and machine reliability. The Brother limited warranty does not apply to any problem that is caused by the use of third party drum units, toner cartridges or toner.

For LIGHT print continue to STEP 1.

For BLURRY, VERTICAL or HORIZONTAL LINES, SMUDGES OR DOTS continue to STEP 4.

1. Check the Toner Save setting. If this setting is programmed on, all printed documents will be light.

a. Press MENU, 1 (General setup), 6 (Ecology), 1 (Toner Save).

b. Press the UP OR DOWN ARROW key until the display reads "Toner Save: OFF".

c. Press OK.

e. If the setting was changed from ON to OFF print the User Settings list by pressing the REPORTS key and then 5 (User Settings).

We have just changed our drum unit but the drum light is still flashing. The printer is printing though. Any suggestions?

After replacing the image drum cartridge, reset the drum counter to keep a correct count of the number of pages printed on the image drum.
1. Turn the printer on while holding the MENU 1/Menu 2 button. USERMNT displays in the control panel window.
2. Press MENU 1/Menu 2 three times. DRUM CNT RESET displays.
3. Press ENTER. The counter will reset and the printer will go ON-LINE.

It sounds like you need to replace Toner Cartriage

When the print quality deteriorates and the drum light is flashing you can replace teh drum but the light will continue to flash until you reset it. Do this by opening the front of the printer and holding down the Go button for about 4 seconds until all four lights on the display are illuminated. It should be fine after that.

On some printers after you change the drum, you have to reset the counter so the printer knows the drum has been changed. How to reset the counter is as follows:
1. press the ONLINE button to return the printer to off line status.
2. press the MENU button repeatedly until the MAINTENANCE MENU is desplayed, then press the SELECT button.
3. Press the item button until DRUM COUNT RESET is displayed.
4. Press the SELECT button and the Drum Counter is reset.

Hope this helps.
