I agree with allan. In a mono machine, if the charge unit is defective, you get BLACK or for some other models, BLANK.
The same goes for this. Check your PCU's charge unit. One of the edge is grounded.

Good mates.
It may also be that the device detects the original as "paper currency" or similar. I had a case where something similar happened to me.

Exactly. That paper looks like it was colored before it went into machine. No charge at all on magenta would still have the lead edge and side erase voids.

Laser printers are write to no charge. So if you have a problem that is causing a drum to not be charged fully, you will get full bleed color across the entire sheet of paper. If someone has taken the charge roller out to clean it, the charge contact for the roller may have gotten bent.
