How Brave is Jan?

Doubt it be the fuser(100 000life), "just magenta dots".... fuser would be "all smudged" or "black marks" , "the print rubs off" , "paper is creasing or jamming"

Can prove it by stopping a print (open door) when paper is1/2 way threw machine, you need to stop it before it goes threw the hot bit, so you can tell if the hot bit (fuser) puts the marks on the paper.

Transfer roller one would expect to effect whole print Smudged/Faint,uneven density

It will be the imaging unit ( 30 000 pagelife Ouch$ ) or possible leaking toner (if aftermarket)

Remove imaging unit and inspect film you should find image of lines, dots are usually chips or sticky stuff on drum surface, carefull no oily human fingers on surface please.

When stopping machine mid print and perfecting your timing, pull out the imaging unit and look at replica of your print notice if marked and where.

Hope this helps

1. Open the Top Cover on the printer.
   
   
   
   CAUTION: Do not leave the Top Cover open for more than 10 minutes without covering the Imaging Units as damage could result. Use the dark bag that came with the Imaging Unit or opaque paper as a cover.
   
   
2. Remove all four Imaging Units (which includes removing the Toner (Dry Ink) Cartridges attached to the Imaging Units). To avoid Toner spills, hold the Imaging Unit in an upright position.
   
   CAUTION: Do not use warm water or cleaning solvents to remove Toner (Dry Ink) from your skin or clothing. This will set the Toner and make it difficult to remove. If any Toner gets on your skin or clothing, use a brush to remove the Toner, blow it off, or wash it off with cold water and mild soap. Do not attempt to use a standard shop vacuum or home vacuum to clean Toner spills in or near the machine. Shop and home vacuums are not equipped with correct filtration and will contaminate your environment.
   
   
3. Raise the two gold colored latches (front and rear of printer) to unlock the Transfer Unit.
4. Grasp both gold colored handles (center and right) to lift the Transfer Unit out of printer.
   
   
   
   

1. Remove the new Transfer Unit from its packaging or shipping materials.
2. Grasp the two handles on the new Transfer Unit and place the left end into the frame alignment sockets.
   
   
   
   
3. Lower the right end of the Transfer Unit down until it lays flat in the printer.
   
   
   
   
4. Press down on both latches to secure the Transfer Unit into position.
5. Make sure the Transfer Unit is latched into position. Lift up on the right handle to see if the Transfer Unit lifts up. If the unit does not lift it is latched correctly.
6. Re-install the Imaging Units and Toner (Dry Ink) Cartridges.
7. Lower the Top Cover.
8. Dispose of the old Transfer Unit as normal office

There really isnt an easy way to do that.
The transfer belt assembly starts off with a fuse on it to blow immediatly on install, and a counter that is internal so that it will end of life and have to be replaced. It's really not a convience counter but an obsolence counter.

That is normally caused by a bad developer housing.

Is it a ghost of the image or just a repeating defect? In the menu, there is a repeating defect information page that you can print out. Depending on the spacing of the defect, you can determine which component it is.
