Documents that include text and tables are being printed with some of the fonts shown as bold (looks like some were printed over the same font), some showing slight double borders around the font, and just an overall, noticeably, low-quality look. This problem is exactly the same for both Word and WordPerfect. Table lines in Word are printed with wavy vertical lines in tables, as well as with the bad text.
PDFs and printed web pages show no problems.
I replaced both black cartridges; same problem.
I used different fonts in printing text docs; same problem.
I did two cleanings; same problem.
I spoke to a Canon rep recently on an informal basis, and he suggested that I consider purchasing a new printer. This is not a problem for me; however, I would be quite disappointed to have the same problem happen with a new printer.
If you folks can't point to a specific issue, can you indicate whether this is more of a Canon issue or a WP issue.
