Double print

[Paul P Bennett]

I have a canon MG6360 printer and am using refillable cartridges. Lately all my printing is 3 lines of double print then 2 lines of good print and continues in that fashion for the full document. I have done all the head cleaning and alignment drills but to no avail. Would it be worth it to send in for a service or simply buy another printer?

The printer uses bi-directional printing, so the print head has nozzle sets for both directions of print head travel. It looks to me like one nozzle set for pigment black is dirty/partially clogged. Could you upload a scan of a nozzle check?

Thanks Peter for your quick response. Have attached a print test. Not a very good image but it shows the black where the problem is.

The pigment black clearly has some issues with the double image but the BK black is also having some problems, I would try and give the timing strip a clean to see if that will correct the double image problem, and if it doesn’t then here is post which has another solution.

Thanks The Hat, I'll use the workaround until I can get it serviced as I don't know how to get to the timing strip.
Again, the quick response is great.

The nozzle check of the PGBK nozzles appears to be from nozzle erosion (wear). I assume you have used this printer for a lot of text printing? The matrix of this nozzle check is typically printed in one pass (not bidirectionally).

Yes, have done a lot of printing. A replacement is only $179 so it's cheaper to buy new than service.
