⚠️ Print Quality Issue Detected
Troubleshooting Flowchart
Step 1 of 3
Vertical white streaks appear in the same location on every page. What is the most likely root cause?
A
Depleted toner cartridgeThe toner is running low and causing output issues
B
Damaged or dirty imaging drumThe photoconductor unit has a scratch, gouge, or coating damage
C
Incorrect paper type loadedThe paper is incompatible with the printer's fuser settings
D
Corrupt printer driverThe driver software is sending incorrect data to the printer
Step 2 of 3
You remove the toner/drum assembly and inspect the imaging drum. You find a visible scratch mark running the length of the drum cylinder. What is the correct resolution?
A
Wipe the drum surface with a dry lint-free clothClean the scratch to restore the photosensitive coating
B
Replace the imaging drum / toner cartridge assemblyInstall a new OEM or compatible drum unit for this printer model
C
Reinstall the printer drivers on the workstationUpdate or reinstall the software driver on the user's PC
D
Run the printer's built-in automatic calibrationUse the printer menu to run a drum calibration cycle
Step 3 of 3
You have installed a new drum/toner assembly. Before closing the Help Desk ticket, what should you do to verify the issue is fully resolved?
A
Print a test page from the printer control panel or print propertiesVisually confirm output quality with a known-good test document
B
Immediately close the ticket as resolvedThe new part is installed so the issue must be fixed
C
Reinstall the printer on all workstations in the officeEnsure all users have the new configuration
D
Replace the fuser assembly as a precautionThe fuser could be next to fail so replace it proactively
