Streaks in black dye

[Leeloy]

Hi.

I'm using Chinese cartridges and OEM cartridges (Topfilling) (CLI151)



After the second or third refill black ink dye (ink OCP) stripes began to appear to do the nozzle test.



So I cleaned the print head (as explained here), but did not improve.

I ended up buying a new OEM cartridge, but with no improvement.

By doing an alignment print out also failed.



Now after trying everything I decided to print a page (configured as photographic paper) with 3 black bars, and the result was perfect .



But the nozzle test still bad.

What is happening to the nozzle test out bad and printing of 3 black bars come out good?

Sorry for english Google and thank you for your patience.

When you set your paper choice to a photographic paper, some of the other dye-based inks may be used to make 'black' in addition to the Black dye-based cartridge. Nozzle checks force a single color cartridge to print one at a time so you can see how well the nozzles (and printer) are functioning for each cartridge color.

It looks to me like there is a heavy black band at the top of the dye-based Black nozzle check followed by lighter Black coloring. Straight lines like this usually mean a malfunctioning print head and/or logic board. Nature does not like straight lines and so it is probably not something you can fix with soaks or even taking the print head apart. If true, then it won't hurt to try those things, but you will need patience to allow for soaking to work and the end result will be no change. That a new OEM Canon cartridge did not help provides further information corroborating my hypothesis.

One thing you may want to try is remove the cartriges from the print head and then remove the print head from the printer. Make sure the circular grommet-style silicone seal is properly seated around the ink inlet port for the Black dye-based port. If the seal is bad then the black in cartridge's ink outlet port cannot seal effectively at the print head and maybe this is interrupting ink flow. Also, make sure there is no ink gumming up this area of the print head -- probably not as you have already "cleaned" the print head. I doubt this will work but at this point you have nothing to lose except a couple minutes of your time.

The best I can recommend is to obtain a new print head at this time unless new information becomes known.

Aftermarket cartridges are notorious for failure on refilling. They may be good for a one time use only. It is a gamble that could lead to malfunctions with your printer, though probably not the one you are experiencing. Except in rare cases, use only genuine OEM Canon cartridges for refilling.

While the nozzle check for the Black Pigment ink cartridge looks odd -- probably just image artifact -- then you could still use the printer for monochrome text printing. Also, since you successfully

Do an extended nozzle check, out of the service menu, it will show more information than the normal nozzle check.

Here are extended nozzle checks of a good and a bad canon PH:

With MY canons (ip4500, mp810) I get in service mode as follows:
(Doing this the wrong way can disable the printer, so it is on your own responsibility....)
A) Entering service mode:
- make sure the printer is turned off.
- press and hold the [resume] button, and then press and hold the [power] button. (Now you
are holding both buttons down)
- release the [resume] button (but do not take the finger off the power button)
- press 2x [resume]
- release the [power] button
B) Functions available in service mode:
Once you have entered the service mode, you can select one of the functions mentioned
below by pressing the resume button the specified number of times and confirm that selection
by pressing the power button. (btw: to give you some optical feedback, the indicator LED
toggles between orange and green each time the resume button is pressed.)
- 1x [resume], then [power]: extended nozzle check
- 2x [resume], then [power]: EEPROM information print
- and many more, which could mess up your printer if you don't know what you're doing.
C) You can leave service mode by pressing [power] without pressing resume before.

Thanks stratman and martin0reg.

-- Is the printer still under warranty?
I bought the printer in February 2014. Brazil Canon provides 1 year warranty on the printer except that the print head is only 90 days guarantee. I mean, if the problem is in the same print head is no longer under warranty.
The after sales service of Canon Brazil is very bad, just trigger the same in the latter case.

-- More importantly, were the stripes evident when not printing a nozzle check and the paper selection was set to Plain Paper or other settings?
The stripes are seen only when printing nozzle test.
Just realized why I follow the printerknowledge long time (always reading) and I scheduled my PC to the nozzle test every 3 days, and so when I realized the problem stopped printing. If I had continued to print without making the test nozzle would not have seen the problem in black dye.

-- What method of print head cleaning did you use?
As my English is bad put as many photos and videos to explain. I made this video while cleaning the print head, were 2 days.

The driving was:
M - 10' 02"
BK - 8' 59"
Y - 12' 11"
C - 5' 37"

The pigmented black (PGBK) was very slow. I left the night and when I woke up it was empty, but do not know how long it took. And I did not leave this until no more ink.


Another problem I have is when I print a table in Excel, for example.
I believe it is an alignment problem, but I tried to align the Automatic and Manual and unsolved.

Do an extended nozzle check, out of the service menu, it will show more information than the normal nozzle check.

Good video. Thank you.

Have you tried placing the print head on the paper towel with your cleaning solution filling up the container to rise above the ink inlets? At this point, pharmacist's solution, original Windex with Ammonium D (or similar), or a liquid dishwashing soap could be tried.

I still recommend you call Canon Tech Support and explain the problems, especially that the printer will not do a print head alignment.

If nothing works, then consider a new print head, part number QY6-0082-000 or a new printer if the price is right. Call Canon Sales as they may have best price compared to eBay or some other seller. At least that is the situation in the USA.

please check PGBK bi-di values on manual printhead alignment page 1 (of 3). It is black column, typically called "C". Which value is best?

Set highest possible value then, and test it with regular print in simplex / plain paper mode.

check your timing strip that runs through behind the printhead. it may be dirty

General troubleshooting approach is right, but not this time.
Other colors than PGBK are OK.
