Is there a website that will explain which faults produce which printing
problems I.E ghosting of the image down the page ETC I have a laser but it
has a few printing faults but I don't know which bit is causing it and I
don't want to buy a new toner if it is something else causing it

Lexmark RT+ is the printer I have three second-hand image drums all with
print problem but I don't know if I have a underlying problem or all the
drums are U/S
I keep getting a ghost of the print further down the page and it also makes
the white slightly darker all over the page and as the price new drum is
extortionate I was hoping to get a rough idea before I source another drum
I don't have any error codes on the display and apart from print quality it
appears to be working ok

Trying a new toner cartridge is a good idea. However, I have seen this
issue before and it was the fuser assembly.

Does the printer have a high page count (like 200,000) ?

Repetitive Defects

Possible Cause Recommended Action

1. Toner cartridge is damaged. If the

defect repeats at any of the following

intervals and in the direction of paper

movement, it is associated with a

component inside the toner cartridge. See

figure 7-10 on page 408.

Inspect the drum for scratches or damage.

Replace the toner cartridge.



2. Transfer Roller has toner on it. If defects

occur on the back of the page at intervals

of 61mm (2 3/8 inches), the Transfer

Roller may be dirty. This problem

sometimes corrects itself after a few

pages.

Clean the Transfer Roller using a dry,

lint-free cloth. DO NOT touch the Transfer

Roller with your fingers. If the problem

persists, replace the Transfer Roller

Assembly



3. Rollers are dirty. Any dirty roller in the

paper path may result in a repetitive print

defect.

Examine and clean the rollers in the paper

path..



4. Fusing Assembly is dirty or defective. Clean the Fusing Assembly using
alcohol.

If the problem persists, replace the Fusing

Assembly.



5. Gears are worn, causing slippage or

jumping.

Inspect the gears driving the toner

cartridge and the Fuser. Replace the Main

Drive Assembly if necessary.



6. Paper does not meet specifications.

The surface of the paper may be too

coarse, causing repeated marks.

Try a different media or paper lot.

247000 odd pages??
I will read through the list and have a go
I did manage to replace the laser a while back after a printhead failure and
looking at the fuser its marked

Then it is likely the fuser assembly. I know that HP recommends replacing
theirs every 200,000 pages.

Post the exact distance between the original image and the first ghost.

This will help identify whether it is the image drum or the fuser that is
at
fault.

the ghost is 5 inches along the paper path which seems like image drum size
to me
