I've got a machine with a similar issue that we are now at the point of getting canon to come have a look.
have you changed the patch sensor?
have you checked to make sure the patch is appearing correctly on the ITB during warmup? (remove the delivery tray cover and power up the machine, view the patches on the front side of the machine where the K patch is generated).
if the patch is fine but it errors replaced the patch sensor.

Blur ?
that mean a lot on a COLOR PRINTER
==========================================
Did u Perform a REG-CLR in Service Mode, and then running a Auto Correct Color Mismatch & Full Auto gradation to try and correct the Color Registration issue.

Using OEM BLACK DRUM ??
The new style hopper is installed.
Registration Patch Sensor checked or replaced
Cleaned the laser glass with the glass cleaning tool located inside the front cover,
E020-0360 refers to the ATR patch failing to be created correctly or a patch sensor error.
Try replacing the black toner bottleOEM
Make sure the contact for the black developer is NOT bent, this causes a poor connection between the black developer and the DC controller. The part number for the contact is FM3-8111-000. See the following photo of the damaged developer contact.

morning all,
Toner in original and hopper in new one,Path sensor not yet replace.
may i know how to the calculation the toner value in this machine.
my machine the DENS>REF> value now is below 55 value in not normal.

good information
wish posters would list exact models & serial numbers > helps with pubs that list affected boxes
just found this pub from y2013

As GohKahWai had mentioned earlier, we had replace the new NPG-52 BK Drum, the new Toner Feed & cleaning & servicing everything. But the best result is only last a few thousand copies. The affected machine serial is FAN13099. Here I also attach a sample of the PG10.

Need to look at both tech pubs,
Black is being starved

Yes, it's look like the Black is starved. As we double check the Toner Feed, there are toner inside. So today, GohKahWai also replace the Patch Registration Sensor together with the BK Drum. The sad parts is the same problem again. The black began to turn out blur. As the reading is Display>Dens>Dens-K> -0.20%--_---_--

The first unit we had replace everything as following from the service manual & additional with the Main Controller PCB but still cannot solve the failure. The second unit is just parked in our workshop
