A dirty or clogged print head will affect the print performance of the Canon Pixma iP90 printer, causing printouts with missing areas of ink or faded sections. When the printer's ink leaves the cartridges and goes through the nozzles in the print head, occasionally some droplets dry early. To clean the dried droplets of ink from the print head nozzles, run the printer's cleaning utility, which flushes ink through the nozzles to force out any obstructions.
- Skill level:
Turn on the iP90 and the attached computer. Start the operating system, then click on the Windows or "Start" button on the left side of the task bar.
Click "Devices and Printers" to launch a new window. Right-click the iP90's icon, then click "Printing Preferences" in the menu that appears, launching another window.
Click the tab labelled "Maintenance" in the new window, then click the "Cleaning" button. Click one of the three radio buttons to clean either the black, colour or all print heads.
Click the "Execute" button at the bottom of the window, then click the "OK" button in the message that appears. Wait for the printer's "Power" light to stop flashing, indicating the printer has finished cleaning the print head.
Click the "OK" button in the new message that appears and wait for the printer to produce a nozzle check pattern printout. Click the "OK" button on the screen if you see breaks or fading in the check pattern printout. Click the "Deep Cleaning" button and repeat the same process as before. If you do not see breaks or fading in the pattern, click the "Cancel" button.
