Then, it began not printing parts of lines, and this seemed to get worse the more jobs I printed. I discovered that this only happens in Fast print quality and in grayscale. Printing in Standard printquality and color is perfect. Do I need a new print head? Is one even available? What about re-installing the driver? I have already tried several things. I have removed the print head, and cleaned it with distilled water. I have replaced cartridges. I have changed the Print Area Setup.</P> Thu, 28 May 2015 17:55:01 GMT Ohwow 2015-05-28T17:55:01Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/Upper-or-lower-parts-of-some-lines-don-t-print/m-p/141971#M11832 <P>Pixma iP4200 printer worked fine for six or so years with light use.
