MG7120 PGBK problem

kaitp — Thu, 18 Aug 2016 17:24:54 GMT

Since changing the ink in my canon MG7120 printer, we've been having this issue. All other colours print fine. I have tried deep cleaning and aligning the thing several times.

Any ideas? Would a new ink cartridge maybe fix the problem or am I better to buy a new printer?

I hae same problem. Tried everything. The only fix I found is to print without the PGBK ink (by changing the paper type to matte photo or high-resolution paper). This sucks since I only print documents & the PGBK ink is better/clearer typically. Plus I'm sitting here with a bunch of PGBK ink that I can't use.

Any help from canon (besides take it in to be serviced). I'd do that if they paid for everything but I doubt that is the case.

Any help would be much appreciated!!!!

I'm so angry about this. I puchased a printerhead cleaning kit. I spent a whole day cleaning the printer head. I purchased all new ink. I wasted a ton of ink doing a bunch of nozzle checks, deep cleaning, etc.

The only thing that works is NOT using the PGBK cartridge which is SLOWWWW and WASTEFUL.

Its CRAZY that canon won't give us a new printer head for free. Heck I want them to also give me replacement ink for what I wasted trying to solve this problem that is obviously in their hardware or firmware. Ugh.

Hi sugarpop,

To get your PIXMA MG7120 printing correctly, please clean the encoder/timing strip inside of your printer.

To do this, please follow the steps outlined in the following Knowledgebase Article:

I have tried cleaning the encoder/timing strip. Doesn't help.

I tried to clean the encoder/timing strip and that didn't resolve the problem. I replaced the PGBK cartridge and that didn't change anything.

Should cleaning the printer head correct the problem? I did that first and it didn't make a difference.

Need other suggestions please.
