Canon MF8280; changed cartridges, now printing pretty colored bars; I have rebooted everything, symptoms remain. I had previously changed 2 other cartridges without issue

While I see no spilled toner, and the stripes are very uniform...not streaks.....the more pages I put through the printer, the fewer pages have the stripes. I am not thrilled, but eventually after using a bunch of paper and toner it looks like I'll be OK. I am a hundred pages in now, and only every 6th or 7th page has stripes....it was all of them before

Hi jreilers.

When changing toner cartridges, it is recommended that you perform the quick gradation adjustment.  This setting will adjust the gradation of colors, based on the information that was acquired when you performed the initial full adjustment.  Please follow the instructions below to perform the quick adjustment:

• Adjustment starts. In approximately 1 to 2 minutes, the adjustment is finished.
