| Step | Action |
| 1 | Begin by powering off the printer. In addition, unplug the printer from the wall outlet. |
| 2 | Remove the leaking toner cartridge installed. IMPORTANT! To seek warranty replacement for the leaking toner cartridge, hold onto it. The cartridge may need to be returned to get credit for any replacement cartridge. For information on how to seek a warranty replacement of a toner cartridge, contact Lexmark Technical Support. |
| 3 | Using a dry, lint-free cloth, clean out as much of the loose toner as possible. |
| 4 | If you have access to a small toner vacuum, try to vacuum as much of the toner out as you can. If possible, remove the transfer roller and check the area underneath for toner. IMPORTANT! Use a vacuum equipped with a HEPA or similar type of filter to prevent any airborne contamination. |
| 5 | Once you have removed as much of the toner as you can, reinstall the transfer roll (if you removed it). Install a different/new toner cartridge. |
| 6 | Plug the printer in the wall outlet and then power it back on. Confirm that the printer powers up to the 'ready' status. |
| 7 | Try printing again. If the printer works correctly and the quality of the print is good, continue using the printer. Monitor the printer for the next few days to see if any print quality issues occur. |
| 8 | If the print quality issue continues after replacing the toner cartridge and cleaning the printer, check the charge roll assembly and the transfer roller (see the pictures below). If the surface of either roller appears dirty, take a clean, dry cloth and clean off as much toner as possible. If either roller surface is damaged, or if you are unable to remove the surface toner, replace that part. |
