Your Canon PIXMA MP190 is an ink jet printer and, as such, contains a print head. This device contains all the nozzles that spray the ink on to the page. These nozzles can get jostled during a cartridge change, which can adversely affect the quality of your printer's output. If you've recently noticed your print quality declining, including hazy images or lines, run a print head alignment to address the issue. Canon has built a utility into the MP190's driver that will help with this task.
Verify that there are at least two sheets of paper in your printer's feeder. Open the front hatch, and extend the paper tray which will catch the printed pages.
Click "Start" from your Windows desktop, and click "Devices and Printers." Right-click your Canon PIXMA MP190, and click "Properties."
Select the "Maintenance" tab, and click "Print Head Alignment," then click "Align Print Head." Your printer will print a single sheet with a pattern of boxes aligned in columns. Each column will be marked with a letter.
Click "Yes" to affirm that your pattern printed properly and to load the alignment worksheet. Look over each column on the printed sheet and find the numbered box in each column that contains the cleanest print. Most boxes will print with white lines running through them, each column should have one that looks proper. The number may change from column to column.
Input the number for each column into the Alignment worksheet on your computer. Click "OK." A second sheet will print that contains more columns.
Repeat the aforementioned procedure to complete the print head alignment. Click "OK" when you have finished inputting the numbers for the new columns. Your print quality should return to normal when this procedure is complete.
Perform a print head alignment any time you change an ink cartridge.
