I've had this post on another forum without any luck so thought I'd try here. My printer has not been used much since buying it 2 1/2 years ago; mostly a nozzle test pattern every week or two to avoid clogging and maybe a dozen or two color photos so it's a like new machine; always lived under a dust cover. Recently it showed a lighter than usual light magenta and light cyan color bars and very slight light streaks in the full strength magenta and cyan color bars. Cleaning the print head by following the many posts on the net fixed the problem but may have led to a new one. To avoid a lot of repeats know that after every cleaning mentioned below were an hour's oven bake at about 120 F and several regular and a deep cleanings and cleaning the contacts in the print head carrier.
Prior to cleaning the print head I had never had a problem with the pigment black ink fine line grid test portion of the nozzle print test. Now with all the color test parts perfect maybe 8 - 15 random line segment were missing. I had switched to G&G cartridges when the originals ran out. Several net forums have cited pigmented black 3d party inks as being prone to sediment problems. I assumed my repeated flushing, air blowing, soaking on Windex tissues etc had stirred up some of this and now had to be cleaned as well.
Now begins my real problem. After taking apart the print head (removing the nozzle plate) for maybe the third time and doing all the cleaning steps my first nozzle print test had no pigment black print at all! Not the grid pattern, not the margin 3eBK label...blank, although the color parts were still present and perfect. This next step is significant I think. Repeating the print head dis-assembly and cleaning and running a nozzle print test I got a total blank sheet...not a drop or smudge of ink to be seen and no amount of cleaning by any means has altered that at all...DOA.
I get no orange failure coded blinking or pop-up error notices and get the same results (no print) whether with the printer on-line or off. The printer acts normally during the nozzle test with paper feed pausing and the expected green light blinking and steady. Same with trying service manual printouts using coded power and resume button push codes...the actions look OK but no print. I have moved the print head carrier by hand to look at the parking pads but net forum posts say that's allowable. Could it have caused a timing error?? I took the printer apart also to clean out the drain lines from the parking pads. This didn't cause any orange error lights nor did it fix the problem. The sudden and total nature of the failure feels like an electrical fault and careful as I was, I may have missed some moisture in the print head or flexed it's printed circuit cable one time too many although it's impossible to tell without extreme magnification viewing.
Most forum posts use a process of elimination for complete failure; trying a new print head and if that doesn't work then blaming the logic board. I haven't found any Canon test to isolate which is faulty? I hesitate to gamble $60 on a new print head when the problem may be the main logic board. Suggestions??
