Try to swap staple cartridges between tehm to see if work. Eliminate worn stape from staple cartridge.
If the same stapler have the issue, like I said , could be a problem with stapler head.
Yellow and magenta make red. If you are seeing yellow magenta isn't printed. Try swapping magenta drum with cyan drum to see of fixes red and problem then moves to green coming as yellow. If that's the case replace defective drum
Call in for service for the staple issue. Or both issues
I did try swatching the magenta and yellow drum, will try witht eh cyan and see the results.
I chaecked the ROS unit they are clean, the cyan one though seems like the dust is under the glass or so cause wiping and have issue still.
Staples, well one catridge stapled others didn't and we changed both. cause both were empty.
When take them out you see some staples like stuck to the top of the cartridge.
The staples seems to be jamming in the cartridge funny cause they are new.
I did put a new drum in the yellow
maybe needs a new magenta?
Check and replace the Yellow drum. And for the stapling, sometimes staples heads may fail.
Having some yellow lines show up on the red prints
check out the photo of a Magenta drum test
Also installed two new staple cartridges but they don't work booklets doesn't staple.
