Canon S530D inkjet printer, uses the BCI-3 series of ink cartridges.
I had a clog that "clean" and "deep cleaning" functions did not clear. I
decided to try cleaning the print head. I removed it (easy to unlock) and
took out the ink cartridges. I used methyl alcohol (rubbing alcohol) to
clean ink feeds in the print head assembly and the print heads. I let the
print heads stand in the methyl for a few hours.
The print head looked very clean. After carefully drying, I reinserted the
ink cartridges ( 3 color and 1 black) into the respective slots, and
reinstalled the print head assembly into the printer.
A print head test (from driver software control) showed that each of the 3
color heads and the black head printed close to a perfect pattern formation.
However, the color control is off. That is, I get orange but no red or
close to red color, either in the test pattern or in printing from a known
source with definite reds present. Also, when printing in grey scale only
(driver grey scale only box checked), I get blacks, some tones of grey but
other mid-tones of grey come out as a light green.
My guess is that something in the print head or conductor lines associated
with the print head, got broken and/or crossed causing the ink flow control
to no longer correctly respond to driver inputs.
Any repair thoughts, other than buy a new print head assembly?
