Canon MX922 Printer PGBK printing double characters (replacing the print head fixed the problem)! :)

Canon PIXMA MX922 Printer Steps I went through to discover a fix: 1) The purpose of this video is to help you fix the double characters when printing PGBK black characters on a Canon MX922 printer. 2) My printing problem started when I was printing a document, and I noticed that the black ink was getting lighter, and then I started seeing blank parts on the document where the black ink would be printed. After 1 or 2 minutes, I started getting blank pages altogether. IMPORTANT. As soon as you see the black ink printing lighter… stop printing and replace the black ink cartridge, or else you will totally damage the print head. 3) I attempted to clean the print head using a solution of 4 parts regular Windex with 1 part 91% isopropyl alcohol. a) For the first attempt, I just soaked the print head without taking it apart. b) I then tried using air pressure to blow cleaning fluid through the holes. c) I then took the print head apart and used air pressure to blow cleaner through all the holes. d) Note: Using the air pressure may have damaged the PGBK black color. I do not think so, however it is possible the excessive air pressure damaged the print head. 4) After cleaning, the colors printed fine, however the PGBK black color was printing double characters, and printed wavy black lines instead of straight black lines. 5) A workaround solution for the double PGBK characters is to select “Glossy Photo Paper” in printer preferences. However, this causes the little black ink cartridge to be used instead of the PGBK ink cartridge. Note: PGBK ink is harder to smear. 6) Steps I went through to fix this problem. a) Tried cleaning the print head (at least 5 times). b) I have taken the printer apart several times, to try to diagnose the problem and to clean the timing strip. Important… before lifting the scanner from the top of the printer, be sure to remove the three little wires! I forgot this step, and ended up damaging the connector on the circuit board. It took several attempts, however I did manage to solder on a new connector (what a pain). c) Thoroughly cleaned the timing strip, however there were still a few spots of black ink drops that could not be cleaned off. You can carefully clean the plastic timing strip with isopropyl alcohol, but do NOT clean the grease off the aluminum track beneath the timing strip. It is there to lubricate the aluminum track the print head glides on. Some people fixed their problem by cleaning the grease off the aluminum track, but this is a mistake. d) Bought a used timing strip on Ebay ($9.99)(it was just as bad as mine) e) Bought an authentic Canon PGBK XL ink cartridge for $30.36 on Amazon. (I used this up trying to fix the problem). f) Bought a used print head on Ebay ($37)(same problem). g) Bought a brand new timing strip from Canon parts for $1.53 + $7 (shipping)(same problem). h) Bought a brand new print head from Canon Parts for $87.20 + $7 7) Learn from my mistakes! Buy a new timing strip ($1.57) and a new print head from Canon ($87.20) + $7 (shipping). You cannot order these parts online. However, you can easily order new parts if you call the Canon Parts Ordering Center (866)481-2569. 8) You can use the cheaper ink, however, keep the ink fresh in your printer, and make sure you do not run out of ink!
