Does not print dark enough to read. Changed toner and adjusted print darkness feature. Still does not work. Any idea what to do?

Hi..
Not just the print cartridge but make sure that the "Print Head" is also working fine. ink clogging has not taken place on print head.... Print head is a hardware, on which cartridge is attached.
Hope this has helped you.. Thanks..

Replace toner cartridge

In your label software there should be a setting option for print darkness (I assume it adjusts the head temperature) In ours (bartender) you can get to it when you select 'print' and a window appears with a 'documents properties' button. Click on this and select options and a darkness bar appears which you can adjust. You may also need to slow the label print speed if the darkness adjustment is not enough. I suspect it isn't in the printers best interest to run the print head at maximum darkness/heat so a sensible balance of darkness and print speed is best.
Another, less likely, possibility is an incompatability between the label material or surface finish, and the ribbon type. We did have a problem once whem Homebase changed their price label design and we had to test a load of other ribbon types until we got one that did the job. A chat with the label or ribbon supplier is always usefull, they sent us several sample bits to test.

go to the print settings select the dark scale
u can get print darker than the previous

change your printer setting to BEST PHOTO setting

If you have installed the toner cartridge correctly then it is a hardware problem called the Fuser and is the most common problem with printers...the fuser is a part of the printer which actually melts the toner onto the paper. The fuser has to get up to a high enough temperature to be able to melt the toner, if it is malfunctioning then it cannot give you a dark print. You may search google for Fuser information: Recommendation is change out fuser to repair problem. Pls rate this solution.

there r two possibilities for this problem 1)either the printersettings are not set properly.try to set all the settings on darkl mode .if not getting perfect setting.just reinstall the printer drivers again,.as reinstallastion automatically sets the printer settings to the required . 2)the other thing is that the optics lens fron where the rays gets passed on the lens which reads the cartridges is got dirty and needs cleaning. to see the picture of optics lens just click the link theimage of lens /optics of a printer

hi!!!!!

try to re-install the driver of your printer!!!
or try to figureout the settings of your printer

1. Check TONER SAVE setting. If this setting is programmed "ON", all
printed documents will be light.

a. Press MENU/SET, 1 (General Setup), then 6 (Toner Save).

b. Press the top or bottom navigation key (keys located above and below
the MENU/SET key) until the display reads "Toner Save: OFF".

c. Press MENU/SET.

d. Press STOP/EXIT.

2. Check the PRINT DENSITY setting. This setting allows you to adjust
the print density from light to dark.

a. Press MENU/SET, 2 (Fax), 1 (Setup Receive), then 6 (Print Density).

b. Press the up navigation key (key above MENU/SET) to make print
darkeror the down navigation key (key below MENU/SET) to make print
lighter.

c. Press MENU/SET.

d. Press STOP/EXIT.

If the print can be rubbed off then this suggests the fuser unit is not working correctly. It could be that the thermistor is covered with toner and making the machine think the fuser is hot enough when it's not.

The black line could also be caused by the fuser if one of the pick off fingers is coated with toner or has worn into the Teflon of the roller.

Does the machine show the lines when you print a page from memory - such as a counter or config page? If not, this would suggest the optical path is dirty. Try cleaning the glass and look at the mirrors inside the scanner to see if they are dirty/dusty.
