Copy is too light after installing new toner and drum,

IS IT REPLACE TONER OR REPLACE DRUM. IF DRUM OPEN FRONT AS IF TO REPLACE TONER AND DRUM, LEAVE DOOR OPEN, DEPRESS I THINK MENU BUTTON OR ONE OF THOSE ON RIGHT SIDE OF KEYBOARD IT WILL ASK YOU REPLACE DRUM 1 FOR YES 2 FOR NO. IF COPY IS GOOD SAY REPLACE, IF COPY IS BAD, REPLACE DRUM, COMPATIBLES DO WORK.

When you were replacing the drum did you tuch the drum surface?Best would be that you take some toner on piece of cloth, and polish the drum, while turning it in good direction, that the cleaning blade can clean it.After you must let it copy about 50 copies.

You can try to replace the whole drum unit cexv14, or clean the laser unit.

Also could it be that the toner unit, or toner cleaning blade are not properly distibutes the toner accross the developing/toner cylinder

check your OPC drum life, if you have a poor quality with a new cartridge installed (light copy, dirty copy) the opc drum must be replaced, check you machine counter if you have reach 100k copies you need to replace the drum, if you are using a new OPC DRUM, you need to clean the machine, you have to call for service because there is many parts that muat removed to clean properly.

OPEN top cover make a copy see if copy exposure lamp turns on or not

Hi
Please follow the bellow instruction…
Open the front panel.
Remove the toner and the drum.
Remove the toner from the drum.
On each side of the toner, there should be a little glass. Put the piece of duck tape on one of them.
Put everything as it was.
Turn on your printer.
Now, the low toner light should be gone and the green light should be on.
Now, you can empty your cartridge.
If the Drum light is still lit after replacing the drum unit, the Drum counter may not be reset.
Reset the Drum counter as follows:
Open the front cover.
Locate the control panel button under the LED lights on the left side.
Pres the control panel button until all lights are lit, and then release it.

The Drum counter is now reset.

check you drum charge connection between drum unit and developer unit, two metal strips at back that contact when the two unit are closed. none or bad connection means no charge and then blank copies

Check the toner supply, it may be running out of toner. Check the bottle or cartridge for correct install. Turn the machine on and let it warm up, Recheck the copy quality. If it is still light run a dozen blank copies, then a test copy if it is improving the toner is depleted and need to catch up, if it isn't there may be a problem with the toner add system.


Hope this is of some help.

Drum may be defective must be repalced.

When replacing drum, be sure to reset the drum counter for HL 5150D:
-Open the toner compartment door, and hold the go button for 5 seconds.

This Machine needs a copy cartridge. Replacing the toner will not clear it. The copy cartridge is the drum unit which is why the drum light is on. With the new copy cartridge a chip on the cartridge will reset the counter and clear the "CC" and the drum light. If you cant find this I can send you one. I believe on this model it is user replaceable.
