Try printing again. Print 20 to 30 pages to give the spots/streaks a chance to clear up.
If a different toner cartridge corrects the issue, the printer is fine and the problem is with the first cartridge. If you have narrowed the problem to the toner cartridge, please carry out the following checks on the cartridge:
- Confirm that you are using an original Lexmark brand toner cartridge. If a third-party cartridge is causing this issue, please contact the point of purchase to have the cartridge replaced.
- Confirm that the toner cartridge has not been refilled or reworked in any way. Refilling the toner cartridge can cause damage to the cartridge, which can cause print quality issues of this kind. If the cartridge has been refilled or reworked, contact the place where the cartridge was refilled to have it replaced.
- If this is an original Lexmark toner cartridge, inspect the toner cartridge for any damage or defects. If you notice any damage to the cartridge or loose parts on it, please contact Lexmark Technical Support. Your toner cartridge may be eligible for replacement, depending on how old or used it is.
Note: If the toner cartridge does not appear to be damaged but is relatively new or unused, it may still be eligible for replacement. Please contact the point of purchase first as they may have a replacement policy. If the cartridge was purchased directly from Lexmark, please contact Lexmark using the phone number or address you used to order the cartridge.
