I have a Dell 2330d which has print quality issues; text on is normal on the left side of the page and fades to barely visible on the right side.
These are the steps I took to troubleshoot:
1 Check LCD screen for messages. Says toner life at 50%.
2 Remove toner and shake.
3 Reinstall toner and print. Prints OK.
-Problem returns several days later.
*Is it possible that consumables were installed by user, and a counter never reset?
*Is there a way to verify page count on currently installed toner and drum?
At this point The problem is either-
1 Toner is low
2 Drum needs to be replaced
3 Fuser is damaged
There is another printer of the same model available to swap consumables with, but what happens if I swap toner and/or drum with the printer that is working OK? Will the swap reset the counters, and make the drum and toner life inaccurate?
Would you swap first the toner, and then the drum to see where the breakdown is occurring? Is there a way to isolate the problem during the print process, without swapping consumables with a known good printer?
How would you troubleshoot the issue?
