Canon MG5350 - big problems with vertical lines

[domina]

Hello, my printer has big problem with black vertical lines. You can see a actual printing result in the attached image.

Notice that the problem mostly occurs with black. It gets better when i rise the printing quality, but it is still far away from good. The attached image was printed with medium quality.

Priting head align doesnt fix the problem. Ive attached an image of the manual printing head align. In column C no field looks good.

Any ideas what to do?

I think there is a problem with the pigment black nozzles. Could you upload a standard nozzle check, if that is possible from your Linux install?

Here you are.

The first thing I would try would be to clean the timing strip on your printer, you’ll find this little plastic strip running from left to right just behind the print head, just rub it both sides with a cloth soaked in alcohol or Windex..

Looking at the full rez image of the PGBK matrix, it appears that your print head nozzles are worn or partially obstructed. There is evidence that PGBK ink is being mis-directed onto the paper. Also some lighter colors are not present in the nozzle check?

The zig-zag appearance of vertical lines in the first test print could be caused by a dirty timing strip as suggested by The Hat, so try cleaning the timing strip.

But there are also problems with the print head, looking at the high-resolution nozzle check I agree with turbguy, that the pigment black nozzles are partly clogged or worn, and regular cyan is too weak, and medium and light cyan are missing. Regular magenta is too weak and medium and light magenta are missing. Yellow is also too weak.

So a print head cleaning is also needed. I guess you have already tried nozzle cleaning from the maintenance tab in the printer driver? If not then try this cleaning first. There is no reason to use the intensive cleaning, as this stresses the print head much more than the regular cleaning. It is better to do two or mere regular cleanings with pauses between cleanings than using the intensive cleaning, as nozzles are fired during the cleaning process, and the nozzles need a flow of ink to cool them. For the same reason only nozzle checks should be printed until the print head problems are solved. No documents or worse, photos should be printed.

In case nozzle cleaning from the maintenance doesn't bring any improvement, cleaning of the print head outside the printer is necessary. Here is a gentle method I have used successfully. More radical methods for print head cleaning exist, but they have a higher risk of damaging the print head and likely also the logic board in the printer, making the printer a total loss.

When a Canon print head fails, there is a risk it also damages the logic board in the printer. A damaged logic board can damage a new Canon print head, so replacing a defective Canon print head is a gamble.

I can only add to that by saying, try flooding the purge pads with Windex before doing any further head cleaning maintenance.

Pull the power plug when the print head is in the middle of the carriageway then really flood the pads and wait a minute or two before powering on and doing one deep head clean which will give the purge pump a good work out also.

Leave the printer to sit for an hour before doing another nozzles print and then see if there’s any improvement between them both, don’t be tempted to try any more photo test prints till you can get a good nozzle check print, patients has it’s own rewards !

I find that simply closing the lid on my i9900 causes the purge pump to run and empty the pads without wasting ink - that's how I run several pad/tubing cleaning cycles before putting a printer into storage.

@domina
I noticed your thread on the druckerchannel.de forum, and noticed that third party inks were used, so are you refilling Canon OEM cartridges, and if so with what ink and using which method? Are you refilling third party refillable cartridges or third party single use cartridges of what brand and using what ink? Are you using third party single use cartridges and if so what brand and type?

Bad inks and cartridges have ruined many Canon print heads, so only refilling OEM cartridges with a quality brand ink is recommended. An ink brand that is recommended by many forum members is Image Specialists that is sold in EU by Octoinkjet UK. And here is a German supplier of inks for the MG5350. I don't know which inks to recommend. OCP is used by some forum members, so maybe that is the best of the inks offered by Octopus-office.de?

I noted the picture of the underside of your print head on the other forum. It looks to me like one of the black cartridges leaked and in doing so probably flooded the purge unit. The purge unit is vital in keeping the print head in good working condition, so as suggested by The Hat and Grandad35 the purge unit should be tested. Also make sure no cartridges are leaking, as leaking cartridges can do a lot of damage.

Ive tried to clean the timing strip before ive posted my thread, it doesnt work.

I use these cartridges http://www.amazon.de/gp/product/B002Q4RXF8/ref=wms_ohs_product?ie=UTF8&psc=1 and the ink from this shop http://www.inktec-tinte.de/Inktec-D...fill-Tinte-fuer-Canon-CLI-526BK-Patronen.html

Iam using the same ink in my ip4950 (same printing head) with no problems. I dont use oem cartridges for refill because there are black and you dont see how much ink is in the cartridge. How i can make shure that no cartridge is leaking? There was a lot of black color on the purge pads.

After i cleaned the printing head with destillate water the nozzle check look like this:

Good colors, still creepy text.
Should i still put windex on the purge pads.
