Solution

Step	Action
1	Power off the printer and remove the toner cartridge. Click here to see Instructions in Removing the Cartridge . Inspect the printer for toner build-up from a potentially leaking toner cartridge. The images below illustrate typical issues that a leaking toner cartridge can cause. Click on images below to enlarge.
2	Use one of the methods detailed below to install another toner cartridge. If the surface inside the printer is dirty, take a clean dry cloth and clean off any toner and dust before installing another cartridge. Try another brand-new toner cartridge, if available. If this is a newly installed toner cartridge, reinstall the old cartridge removed when you installed the new one. Install a working toner cartridge from another Lexmark printer of the same model.
3	Power on the printer again. Print 20 to 30 test pages to give the spots/streaks a chance to clear up. Did a different toner cartridge correct the issue? Yes: Inspect the first cartridge for signs of damage or defects and continue in contacting Lexmark Technical Support to inquire about the eligibility of replacing the cartridge. No: Continue with the steps below.
4	If the test pages still have unwanted toner marks, select an appropriate scenario below: Check the charge rollers – if the issue occurs on the front side of the page. Check the transfer roller – if the issue occurs at the back of the page.

1	Power off the printer and remove the toner cartridge.
2	Look for the charge roller assembly . This is the twin set of small gray rollers located in the upper area of the printer where the cartridge had been seated. NOTE: Please see the encircled portion of the right-hand image.
3	If the roller surface appears dirty, take a clean, dry cloth and remove any toner on the surface. CAUTION! Try not to touch the charge rollers with your bare hands. The surface is susceptible to contamination, and a permanent mark could remain on the rollers.	No Image
4	Inspect the charge rollers for any signs of damage. If any part is damaged, or if you are unable to remove the surface toner, continue to contacting Lexmark Technical Support .	No Image

3	Check the transfer roller for any signs of damage or defects. Also, using a clean, dry cloth, wipe the surface of the transfer roller. See if the cloth will accumulate toner.

Service action

Confirm that this issue happens with more than one toner cartridge before replacing any parts on the printer. Most print quality issues are caused by the toner cartridge.
Try printing on plain, white copy paper, if not already doing so. This will eliminate any specialty print media as (partial) cause of the problem.
If the spots/streaks on the page appear to repeat at regular intervals, print out the
Print Defects Guide
. This page displays the distances that correspond to the circumferences of various rollers within the printer. To find the Print Defects page, go into the menus on the printer. Select the
Help
menu, then find and select
Print Defects
. Click here to download a copy of this page.
If the printer appears to be the cause of the issue, see the instructions below to run a Developed Image Test to narrow the source of the problem further. Your objective in this test is to stop the printer abruptly while it is in the middle of the printing process, resulting in a partially printed sample not yet fused to the paper. See the instructions below.
Identify the location of the printer and how it is being utilized. If the printer is being used in continuous operation such as manufacturing, courier or label printing, and the environment is slightly hot (e.g. Warehouse or Distribution centers); this can cause overheating of the cartridge resulting in toner leakage. To reduce Thermal Impact on the cartridge, try setting the “
Paper Type
” to “
Vinyl Label
”. (See customer-level section:
Environmental Factors
). If the customer already tried this option, access the printers
Diagnostic Menu
and adjust the
Engine Settings 4
to a value corresponding to the
Tray number
being used. See the list below:
If
Tray 1
is being used, set the
Engine Settings to 20
.
If
Tray 2
is being used, set the
Engine Settings to 36
.
If
Tray 3
is being used, set the
Engine Settings to 52
.

Step	Action
1	Print the Menu Settings Page or any test print job with multiple pages.
2	As soon as the first page begins to exit the printer, either open the upper-front cover or power off the printer. This will stop the printer in mid-print.
3	Remove the toner cartridge. You should still see the second page in the printer underneath where the toner cartridge had been. The print on this area of the page has passed under the toner cartridge, but not yet through the fuser unit. Click here to see an example.
4	Examine the back of the first and second page. See if you can find any spots or streaks. CAUTION! Exercise care as the toner on the front of the page will easily rub off. If the back of the second page has no spots or streaks, yet these appear at the back of the first page, the Fuser unit is the probable cause of the issue. If the spots/streaks do appear on the back of the second page, you can eliminate the fuser as a possible cause. The most probable causes are the Transfer roller or the Toner cartridge .
5	Once you have completed this test, remove all paper jammed in the printer. Again, use caution when removing the pages that did not feed through the fuser unit because the toner will come off.
