2 days of repetitive and continous internal paper jams.
Product: Example: HP Officejet 8725
Operating System: macOS 10.15 Catalina
Appears to be in the area of paper rollout, under the cartridge access cover, in front.
Have cleaned all rollers (front and back, twice), reset printer. All software/drivers up to date. Changed paper, restacked small and larger amounts, 'whiffed' for static electricity, etc.
The pages print just fine; it is after the printing and during the 'exit' of the paper that things ball up. Cannot find any foreign objects, dust, scraps of paper etc. Same thing happens with flatbed copier; original exits ok, the copy gets jammed in same place as above.
