HP CLJ 4600/4650/550/5550 Series: Why Won’t My Toner Shutters Open?

When your toner shutters do not open, what should you do? Often, when technicians encounter these symptoms (no image on the paper or the paper jams two inches onto the transfer belt), they will replace the rollers, pickup assembly and transfer belt when instead, all that is needed is to lift a mechanism. Luckily, there is a very simple fix that only takes five minutes.
1. Begin by removing all of the toner cartridges inside the printer.
2. Next, locate the plate that lifts to open the shutters. See Figures 1 and 2.
3. Lift up on this plate for each of the colors and repeat a couple of times, making sure you lift up on the plate for all four colors.
4. Next, reinstall the toner cartridges and partially close the ETB assembly. Observe whether the shutters are opening.
If this solution does not work, then something might be broken or disconnected. In that case, you will have to remove the left-side cover and all of the cartridge drive assemblies to inspect the mechanism that lifts these up. Usually this is not necessary, though, because it’s very rare when something is actually physically damaged. It may be hard to believe, but the fix is really that simple.
