Reset pcu correctly


Thanks for using FixYa. It means that the photoconductor unit is not set correctly. You’ll need to reset the black or color PCU correctly. Match the green arrow at the tip of the photo conductor unit to the rail inside the printer. Make sure the green arrow fits securely on the rail before proceeding to the next step. If you do not attach the green arrow of the photo conductor unit securely to the rail, you may damage the photo conductor unit. Push the front of the photo conductor unit slowly, sliding the unit on the cover and into the machine until it stops.

Please do accept the solution if the issue is resolved or else revert for further assistance.
