If your printer is showing a print error 9DB8B6 and having printing problem on HP OfficeJet Pro 9010 is generally associated with an internal printer fault that prevents print jobs from being processed correctly.
Troubleshooting steps:
1.Hard Reset the Printer
Turn off the printer using the power button.
If it refuses to turn off, unplug the power cord directly from the back of the printer.
Unplug the other end of the cord from the wall outlet.
Wait at least 60 seconds.
Reconnect the power cord directly into a wall outlet (avoid surge protectors) and turn the printer on.
2.Use genuine HP ink cartridges
Non-HP or refilled cartridges can cause reliability and print quality problems.
Check that the installed cartridges are the correct HP cartridge numbers for your region and printer model.
3.Check estimated ink levels
On the printer control panel, open the Dashboard and touch the Ink Level Indicator.
4.Replace empty ink cartridges
Open the cartridge access door.
Wait for the carriage to stop moving.
Remove the empty cartridge and install a new one.
Make sure each cartridge clicks into place and none stick out farther than the others.
5.Check paper and print settings
Use clean, wrinkle-free paper.
Make sure the correct paper type, size, color, and print quality settings are selected.
For best results, use appropriate paper such as plain paper with ColorLok for documents or HP Advanced Photo Paper for photos.
6.Print a Print Quality Diagnostic Page
Load plain white paper.
On the control panel, open Setup > Reports > Print Quality Report.
Review the report:
If color blocks are streaked or missing, clean the printhead.
If lines are not straight or connected, align the printhead.
7.Clean the printhead
On the control panel, open Setup > Printer Maintenance > Clean Printhead.
If needed, run additional cleaning cycles.
Note: That a badly clogged printhead might require repeating cleaning after 30 minutes.
8.Align the printhead
On the control panel, open Setup > Printer Maintenance > Align Printhead.
