[Error Code] constant error C-2720 on Accuriopress C2060

[Neos Eye]

I got constant error C-2720 on my Accuriopress C2060 every time I open the machine .. I have cleaned all the contacts.. replaced 2nd transfer roller upper and lower, separation grid, replaced bearings on the upper roller, replaced the insulating holder back of the upper roller.. any other suggestions?

I have never seen this code associated with HV2 or the PRCB, but those are the next steps.

Do you also get a C-2221 on occasion as well? I recently had a customer getting a C-2720 and when I got there it was instead displaying a C-2221. This usually occurs when the drum flanges get dirty and cause the process drawer to not close completely. You can check this by looking at the small square hole right above the lower right purple standoff that secures the drawer closed. It should be completely against the sheet metal frame metal behind it. If there is a space of 1 or 2 mm's, clean the drum shafts and the inner rear drum flanges. The square hole is shown as a white dot in the circled section in the bottom of the attached picture.

Here is an actual photo of the square hole. Notice it is completely against the surface behind it. Any gap and you will have issues.

I don't get that c-2221 error code.. I remember before c-2720 happens, there was a constant paper jam. I forgot the code, but the paper always goes up to the transfer unit.. seems like transfer/ separation problem.
