Hello,
I'm afraid my daughter's Canon S820 printer is close to death but just wanted to check here whether there is something I have missed out.
I have read a lot of posts, including in this very valuable forum and I have tried everything I found.
The issue :
Since a while, the printer seems to do a completely wrong mapping of colors and qualities.
When I print a document on ordinary paper and leave the basic settings (Standard quality = 4) and Color Management = Auto, I nearly get a correct printout.
(For my tests I created a color palette page having gray scales, the primary colors and halftones.)
But in this standard setting the printer does some horizontal striping and picture or graphics quality is therefore unacceptable.
This printer has always done that and therefore my daughter mostly used the "Very fine "(1) setting for Print Quality.
Which gave very good results until recently.
But when I now print with this high quality setting, Photo magenta and Photo Cyan are missing completely.
When I specify 'High resolution paper' with quality 2 (Fine) only Photo Magenta is not showing up.
The same paper setting with quality 1 (very fine) is doing the same but other half tones look different, more green.
With other paper and quality settings, such as "Photo", Glossy, etc. behaviour is different but still none of the settings has correct results showing all colors. In some cases even the black color disappears at about 1/3 of the page!
The list of things I have tried and which did not solve the problem:
- I changed carts with my i965 printer (luckily they are the same); I only use original Canon carts but my daughter did use generic ones.
- I cleaned and deep-cleaned the head;
- I tried to realign the head, but that doesn't seem to work at all: all colors are completely striped, from top to bottom, except Magenta which comes out correctly at +1;
- I unmounted the head, put it in water for a night, let it dry;
- I blew the head with a high-pressure cleaning air can;
- I cleaned the cleaning pads and brushes of the printer;
- I cleaned the electrical contacts between the head and the printer.
- I did a reinitialization of the printer's EEPROM .
- I reinstalled the driver and tried several ICM profiles.
Funny enough, when I put the head on a paper towel, all colors come out nicely and evenly:
6 parallel stripes, same length, same width, which makes me say that the nozzles are not clogged.
It just seems the printer doesn't use the colors that it should make use of.
Should I come to the conclusion that this is an electronical problem and that the printer is dead? Or is there still any hope?
I know a lot of devices on which one can flash the firmware but printers don't seem to be part of the list?
Thanks in advance for any help or advice!
