Before you start
- Supported plain laser paper and an example of the actual quality defect.
- Network access and current administrator credential if using the EWS cleaning-page route.
Step 1:Check the paper and job settings
Use paper intended for laser printers, not inkjet-only media. Confirm the actual paper size and type for the tray and print job. In the source’s touchscreen layout, open Trays, select the tray and choose Modify to update the paper details.
Try the same content from another application if the defect may be in the software. A Best quality setting cannot repair a damaged cartridge or correct the wrong paper type.
Step 2:Read toner estimates without treating them as a measurement
From Home, swipe to Supplies → Cartridges. These levels are estimates. A low alert alone does not mean the cartridge must immediately be replaced; HP says to consider replacement when the print quality is no longer acceptable.
Step 3:Print the quality troubleshooting page
Load supported plain paper. Open Menu → Tools under Utilities → Troubleshooting, then choose Print Quality Troubleshooting Page. In the recorded interface, the report choices are inside Print Quality.
Compare the colour groups for dots, streaks or uneven output. HP’s page groups the results by yellow, cyan, black and magenta. Note whether the defect belongs to one colour group or several rather than replacing every cartridge on a guess.
Step 4:Use a cleaning page when the defect calls for it
For specks, smears, streaks or repeating marks, HP documents a cleaning-page route in the printer’s web settings: open its current IP address from the same network, then Print Quality → Tools → Fuser Cleaning → Print. Use your current administrator credential if asked.
Follow the printer’s paper-loading prompt and wait for completion. The recording also offers a touchscreen Cleaning Page; labels can differ. Its Clean Belt option is not an instruction to open the printer or wipe a belt by hand.
Step 5:Calibrate colour when colours do not line up
HP documents Menu → Tools under Utilities → Troubleshooting → Color → Start. The recording labels its choice Color Calibration within Print Quality. Use the equivalent colour-calibration option offered by your printer.
Leave the printer powered until the calibration finishes. Then print the same sample again and compare it. Calibration is useful for colour alignment problems; it is not a guaranteed remedy for every faded or damaged print.
Use the result to choose the next action
HP’s diagnostic guidance connects defects limited to one colour group with that cartridge. Dots across groups can call for a cleaning page; persistent streaks across multiple colour bands may require HP support. Retain the actual sample and error details for support.
The source runs maintenance and expresses an expected improvement, but does not establish a documented before/after repair for every defect. Avoid repeatedly running every maintenance option without comparing the output.
