A new laser could help, but you should make sure the toner save is turned off, it makes toner last longer by making light prints. Toner save is set in printer properties in the control panel

How to troubleshoot the faded printout problem in laser printers?


This is due to this reason:-- A faded print image is normally the result of one of three conditions: The printer is getting low on toner, the print density is set too low, or Econo mode printing is turned on. For the last two settings, a printer self-test (typically a separate button on the printer) will show what the current settings are. If Econo mode is on, and users are complaining about how light the print is, turn it off and/or set the print density higher. If the toner is low, simply removing the cartridge and shaking it to redistribute the toner more evenly can temporarily resolve the problem until you can replace the cartridge. This will help. good luck.

Getting light print on b&w, changing density makes zero change. Toner changed, no effect.


Check whether you are running as Black and White or Gray Scale. Many printers only print straight black by using all four toner cartridges- Cyan, Magenta, Yellow, black. If are running colored print in black and white and u choose grey scale it will automatically give you a screened image as a light print.

[C390] Auto-toner sensor-C abnormality (Cyan)
<Color toner low density>
When you check the printing status to find out that the color printing ratio isless than 5%, color toner low density might be the cause.
Turn the code 08-2692 "Prevention of color toner low density / ON/OFF setting" to ON, and then set number of sheets to be judged at the code 08-2693 "Prevention of color toner low density / Judged number of sheets setting".

If the color printing ratio is 5% or more, check the following.
(1) Is the developer unit installed properly?
(2) Check if the connector CN340 on the LGC board isdisconnected from the auto toner sensor or the harnesses are open circuited. Correct if necessary.
(3) Check if there is any foreign matter such as toner in the drawer connector of the equipment and fuser unit or the connector of the auto toner sensor. Remove if there is and reconnect it.
(4) Service or replace the auto-toner sensor.

The black print on my Dell 1320C laser printer is very light (grey) in fact. I replaced the black toner at no avail. The other colors are fine.what can I do to soulve the problem. ...


It sound like you have either a very low toner density set, which would normally be set either through the control panel or the driver, or possibly the Dell Toner conservation system turned on. Here is Dells owners manual info on dealing with light print.
The toner cartridges may be low or need to be replaced. Confirm the amount of toner in each toner cartridge.
  1. Press [Printer Status], and then click the Status tab in the printer driver.
Ensure Non-Dell Toner is not selected in the Printer Maintenance tab in the Tool Box.
  1. Click the Tool Box button.
Set Toner Saving Mode to Off in the printer driver.
  1. Press [Printing Preferences], and then click the Advanced tab.
If you are printing on an uneven print surface, change the paper type setting in the printer driver. For example, change the plain paper to thick.
  1. Press [Printing Preferences], and then click the Paper Tray tab.
Verify that the correct print media is being used.
  1. See "Print Media Sizes and Support".
Ensure that eight yellow ribbons are correctly removed from the PHD (Print Head Device) unit.
  1. See "Replacing the PHD (Print Head Device) Unit" and "Installing the PHD Unit".
Ensure that the developer motor starts.
  1. Contact Dell.
Ensure that the dispense motor starts.
  1. Contact Dell.
When you are printing many images with low density, do the Toner Refresh Mode.
  1. Click the Tool Box button.
  2. Press the Start button to check the density of colors.
  3. If the print is too light, Select Refresh Mode from the list. Press the Start(1)-(4) buttons.
CAUTION: Using the Refresh Mode consumes extra toner.
  1. After you complete the Refresh Mode, select Chart Print from the list. Press the Print with A4(3) or Print with Letter(C) button for 4 Colors Configuration Chart. "Printing" appears.
    Is the problem recovered?

The copies look faded out as if a new toner is needed, but I just changed the image drum and the toner cartridge


It could be that the print density setting is set too low. Adjust to higher density printing.

If the ink of the toner is not well distributed, remove the cartridge toner from the printer. Shaking it to redistribute toner more evenly will help..

Reset the printer
On the printer press the menu button until you reach MAINT.
Then press the item + button until you reach DRUM CT RESET. Then press select.


That will fix it.

Assuming that you are using the same paper and have not changed any of the consumables you should do the following:

1. Clean LED head with lens cleaner or soft tissue.
  1. Remove the toner cartridge and give it a few shakes then reinstall it.
  2. The Toner Could be low so Change toner cartridge.
4. Make sure that the paper is not damp as this will cause fading and poor quality printing and images.
  1. The image drum may have been light contaminated so remove it from the printer and store it in a totally dark place for several hours then reinstall it.
  2. If the image drum is dirty then wipe it very gently with soft tissues, being careful not to scratch it.
  3. Open the top cover and check to be sure that each toner cartridge is fully seated and that each toner cartridge lock lever is pushed all the way back.

Light printing


I would suggest using the printer's menu and checking both Direct Print->Print Quality and Direct Print->Brightness as these may be set too low or too high. Change these values, 1 at a time, and do a test print to check the print density
