Fading on one side of the paper - Dell 1815dn laser MFP
After replacing a toner cartridge, the right 1/3 of every page gradually fades to nothing, left to right. The left side is flawless. This happens for any printing or copying. I have blown out the cartridge area with air. After multiple cleaning attempts, sometimes there is improvement...other times it gets worse. From everything I've read so far, it may just be some toner that has collected on the laser glass. Dell's support site shows an illustration of the glass as suppsedly being on the top of the cartridge area, but I think this illustration is for a previous model and I see no such glass in my 1815dn. Any ideas on what to disassemble or where to look on this one?

Re: Fading on one side of the paper - Dell 1815dn laser...
The Printhead IS located above the toner cartridge on this model. There is a small opening that allows the laser light to shine through the case to the imaging unit on the toner, but you can not access the the laser without disassembling the printer.
Even though this is a new toner cartridge, it may be defective, even more likely if it is a non-Dell or remanufactured toner. Try reinstalling the old toner cartridge. Even if it prints light because it is low, if it is uniform across the page then the new toner is defective. Return or exchange it with the manufacture.

Dell Laser MFP 1815dn configuration page
To print a configuration page (also called system data report) from a Dell Laser MFP 1815dn printer:
- Press the right arrow button until Menu is the active choice on the screen
- Press the check mark button to select it
- Press the right arrow button until Reports is the active choice
- Press the check mark button
- Press the right arrow button until System Data is the active choice
- Press the check mark button
Take the toner cartridge out and rock it from side to side to balance out the toner (don't shake it). Anytime a cartridge starts getting low on toner it will get lighter; rocking it will stretch a little more life out of it, but plan on getting a new toner soon.
It's possible that this could also be down to a toner cartridge inside the printer. I would recommend running off a copy of the colour laser test page found here.
The colour bars towards the bottom of the page separate cyan, magenta, yellow and black. Hopefully you will be able to notice that one colour is affected more than the others and replacing that colour may help.
Apologies if you have tried anything similar previously.
If the print rubs off the page, this means the toner is not being fused to the page. Fused......this is done by the fuser. This would have nothing to do with light print.
The dell (1600n and 1815n /1815dn) printer drivers has a toner saver mode, which can contribute to light print.
To turn Toner Save Mode off, (Windows XP) perform the following steps:
Click the Start button, click Settings, and then click Printer and Faxes. The Printers and Faxes window appears.
Right-click Dell Laser MFP 1600n, 1815dn, and left-click Printing Preferences. The Dell Laser MFP 1600n, 1815dnPrinting Preferences window appears.
Click the Advanced button. The Dell Laser MFP1600n, 1815dn Advanced Options window appears.
Click to highlight Toner Save.
Click the drop-down list and change it to Off and click OK.
One thing that you mentioned in your post "it takes the printer forever to warm up". The fuser does have to reach operational temperature in order for it to fuse the toner to the page. So it is possible that you are having fuser problems, because of the time it is taking for it to warm up. Another thing that can contribute to the warm up time is not plugging the laser printer directly into a wall outlet. This would be true for any laser printer, not just a Dell laser printer. The low voltage power supply is what works the fuser, along with sensors and other motors in the printer.
Replacing the fuser and or the low voltage power supply in this model of printer is not an easy task. If using a Dell branded toner cartridge and checking the toner saver mode does not fix the issue. Then you would be looking at more expense then the machine would possibly be worth.
If the smudges are gradually fading then it's likely just excess toner hitting the fuse drum. Try a few cleaning cycles/test prints and see if that makes it go away. If not, see if you can get a replacement toner.
Have you tried cleaning the leans at the bottom of the printer? Open the cover, pull out the drum. Under it is a long, narrow piece of glass. If it gets dusty or toner accumulates on it, it will cause streaks in the printing. If this is dirty, take a clean, soft cloth and very gently wipe it off.
