Question about Dell 5110cn Laser Printer
Long story so bear with me. All elements are important to help rule out causes. No one can figure this out. The problem I'm having is that sometimes (mainly after I've printed a job of say 100 sheets or so) I'll get full toner color bands down the left edge of the page (holding the page in your hand). If I keep printing, the toner spreads to the whole page. Sometimes it will be magenta, sometimes, cyan, sometime black, sometimes yellow.
1st occurence - set of remanufactured toner was in printer and printer set to 'non dell toner'. Replace black with Dell brand toner. Other 3 are still non-Dell. Black starts freaking out and placing toner all over the page.
Called Dell - the sent out a new imaging drum & transfer roller.
Installed and seemed to fix problem for 1 week.
Replaced cyan non-Dell toner with Dell toner. Started spreading cyan toner.
Called Dell - they sent out a technician and a new imagind drum & transfer roller. Test print produced cyan bands down side. Technician cleaned the drum & rollers and I printed about 100 more sheets and it started spreading cyan toner again.
Called Dell - they sent out a new printer without toner or imaging drum.
Received new printer - transferred imaging drum & toner (currently all non-Dell at this point because my theory was that the non-Dell setting was causing confusion for the Dell toner).
New printer started spreading cyan again. Thought perhaps my laptop or usb cord was the problem. Hooked my computer & cord up to another Dell printer - no problems after 900 prints. Not my computer or usb cord.
New theory - it's the non-dell toner setting PERIOD. So, I transferred the non dell toner into the Dell cartridges (black & yellow only because I still have cyan and magenta Dell toner). Changed printer setting to Dell Toner. Seems to work for 300 prints. Then I start getting cyan banding again. Now, the cyan is Dell brand 'virgin' toner. 100% Dell. So now I don't think it's the non-Dell toner at all. And now, I have no theories. HELP!!!
First off, this is a comment from a random person who may or may not know ALOT about these printers and toner/printer design in general. All toners are not designed to the same specification. Toner is a combination of plastic "pigment" and iron like shavings to make it magentically attracted to the electrical charges within the unit. Different toners conform to different grades and mainly size of the particles within the blend. The manufacturer doesnt only recommend that you use their toner to make them money, yes of course it makes money, but its because when the unit is designed it is designed to use a certain grade of toner, trust me if you put the non-branded toner vs the branded toner under a microscope you would see quite a difference. Often the non-branded toner is much larger in particle size (obviousely because its cheaper to make at this spec). This causes a variety of issues from excess toner not being cleaned off of developer rollers, IDT rollers, or clogging of toner dispenser tubes in the unit and the micro filters contained at the toner dispenser assy and developer assys. Also as for the issue not changing when switching to dell branded toner - the dispenser tubes within this unit contain up to 500-1000 pages worth of toner, making no change in toner you make immediately visible. Also depending on the damage caused by the previous toner, it may not be able to be fixed until all the components in between the toner and final delivery (drum cart) are replaced. In this case more than likely the toner dispenser assy, all developer assy's, and drum cartridge need to be replaced, and than be sure to stick with factory branded toner :)
