Replace the PCU.

I would actually start with the cleaning unit right below the transfer belt. If it's worn out, it often streaks colors even after you've replaced the PCUs. As for the Calibration failure, I would make sure the chrome like roller underneath the transfer belt is clean. The sensors look through the transfer belt and reflect off this roller.

Depending on the age of the model, it could be a couple of things. ***Never touch the drum or expose it to bright light*** The drum unit is bad. It's the shiny brightly-colored large roller in the center of the machine. On most recent smaller machines like this on it's integrated into the toner cartridge. Check it out. If it has toner build up on the ends, it's bad. or The corona wires need cleaning. Some machines have a small slide that moves from one side of the printer to the other which cleans the hidden corona wires. It's usually brightly colored. The corona wires are also integrated into the toner cartridge in many smaller machines

I have ricoh sp c820dn printer here is message say turn power off then set the pcu correctly .cyan

it looks like the Cyan Unit is not set correctly, so you need to open the front door, in the area behind the front door up you will see the toner bottles under the bottles it has a cream-white plate, you will see in the middle of the plate one handle - leveler which is blocked with a plastic piece, which have a ***** in the middle remove the ***** than remove the plastic piece, after that pull the handle - leveler up to be set from horizontal position into 45 degrees angle upwards. After that in the upper right corner of the plate you will see another handle- leveler. This one you need to set from horizontal position into vertical position upwards. After you move the both leveler, you will need to pull the hole cream-white plate toward you. Inside you will see 4 boxes (PCU's) with green levelers. Put inside firmly the cyan box (PCU) under the Cyan box, below the box writes on a sticker Cyan.. After you do this close back the creame-white plate, put the both levelers into horizontal position and close the the front door. If the problem persist than is not just a small fix...That is for now, if the problem continues please ask more guestions. Good Luck. :)

Aficio SP C411DN does not print cyan

Well, since you've tried everything, my recommendation is to try to clean the contacts with dry cloth in the left or right side inside the printer where the cartridges place in. see the result

There are streaks on the side of the printed page


Are the Streak lines vertical or horizontal ? Most likely it could be due to Toner issue, Try to remove the toner and clean it and re-install it

Printer output has shadows, blurring, streaks, lines, poor color

Seem like blocked hole(s) on the color print head...
Most likely if there is a deep clean option then do it (may need a few times to unblock a hole or never).
Also get the printer physically cleaned up if you can see dusts inside (vrtical lines on color bars).

Light or Faded Areas in Solid Color Prints

If the issue is occuring in the same place on all prints, try the imaging drum (can't remember if this printer even uses one) or the transfer belt/roller (not sure which it uses). If you phone Dell support, they should run you through troubleshooting and send you either of those parts free of charge if you are under warranty. If not, buy them anyways; they don't degrade over time (if kept in the dark) and can be saved for when the currently installed one runs out if you don't need it to fix this issue.
