The images below illustrate typical issues that a leaking toner cartridge can cause. Note: Click on images below to enlarge. |
2 | Use one of the methods detailed below to install another toner cartridge. Note: 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.

Check the charge roll assembly
Step | Action | Click Image to Enlarge |
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 |
Check the Transfer roll assembly
Step | Action | Click Image to Enlarge |
1 | Power off the printer and remove the toner cartridge. | |
2 | Look for the transfer roller. This is the black, spongy roller located at the base inside the printer where the cartridge had previously been seated. NOTE: Please see the encircled portion of the right-hand 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. If the cloth accumulates toner, then the transfer roller is contaminated and needs to be replaced. Continue to contacting Lexmark Technical Support. | No Image |
Check the type of paper
Before calling Technical Support, confirm that you are printing on plain, white copy paper.
If not, try printing on such paper before seeking service to the printer. Please try this even if the specialty media you are using has worked in the past. This tests will eliminate specialty media as partial cause of the issue. Specialty papers (i.e., letterhead stock, textured paper, label stock, and card stock) can lead to print quality issues such as this.
For more information on recommended print media, see the chapter entitled 'Understanding paper and specialty media guidelines' in the printer's User's Guide.
Environmental Factors
If the printer is situated in a hot environment such as a Warehouse or Distribution center; its constant operation may cause overheating of the cartridge. This will cause the toner to leak.
