The 10.92.YY Cartridge Not Engaged error is one of the more common error codes found on the HP 3000 series Color LaserJet machines. The good thing is that it’s one of the easier problems to diagnose. The bad news is that usually one or more of the cartridge lock levers or a slide lever is broken or one of the cams above is broken. Like the swing plate gear in the 4200 series HP LaserJets, the lock levers in this machine were never meant to be replaced. In this article, I’ll talk about the error, troubleshooting the error, and replacing the lock levers.
How the Cartridge Engage Process Works
As the transfer unit opens the cartridge lock levers (four on either side of the machine) move up into the machine. When the transfer unit closes the cartridge lock levers clamp down on the sides of the cartridges and hold it in place. On the right and left side, the lock slide levers moves up as the door/transfer assembly closes and down as the door/transfer assembly opens. When the right white slide lever moves up it engages the cartridge drive motor assemblies by pushing the black cartridge drive gears left so they mesh with the gears on the cartridge. Also, four white tabs on the right slide lever push on the back of the cartridge shutters moving them out of the way and exposing the drums. The lock levers are attached to the slide levers with springs. If any of these parts are broken or processes don’t happen then a cartridge not engaged error can result.
Alright, that’s how the process works. Now let’s move on to the troubleshooting part.
Troubleshooting the 10.92.YY Cartridges Not Engaged Error
This legend gives us a better idea of where to look to resolve the error, but I recommend you check over the whole area to make sure you’re getting all the right parts. In my experience I’ve always had multiple parts break at the same time so I make sure I go over the whole thing before I order parts.
First thing to try is reseating the toner cartridges.
While reseating the toner cartridges pay attention to the ease of how they go in and out. The lock levers should move up when the transfer assembly opens and lower when the transfer assembly closes. If everything seems fine and reseating the cartridges doesn’t resolve the issue, remove them and watch the lock levers as you open and close the transfer assembly. The lock levers actually move with the transfer assembly so if you remove the transfer assembly you can leave the door open and move the transfer assembly holders up and down so the door doesn’t obscure watching the lock levers. If none of the lock levers move on a side or if you don’t feel any tension then one of the cams is most likely broken. The lock slide levers should move fluidly with some resistance due to the springs on the actual lock levers. If there is no tension, feels awkward to move, or you hear a loud clicking sound then something is probably broke in the cam assembly or slide lever.
Switch the cartridges
If everything is moving the way it should and you can’t see anything wrong then switch the cartridges. For instance, if the black slot is giving you the “cartridge not engaged” error then switch it out with the magenta cartridge to see if the problem follows the cartridge or stays with the slot. If it follows the cartridge then replace the cartridge and see if it continues.
The lock levers
If one or more of the lock levers doesn’t move then either part of the lock lever slide is broke or the lock levers themselves are broken. The lock levers on the right side have been updated and come in a pack of four. If these are not moving I would order the repair kit, right slide lever and right side cam. These parts are extremely complicated to remove so I would just order the parts and plan on replacing them all at the same time rather than taking it apart several times to check the parts individually. The parts on the left side remove with only a little disassembly so it’s in your best interest to just remove the High Voltage Power Supply and check all the parts to make sure you’re getting everything you need.
Verify the cartridge gears and shutters are being engaged.
If the cartridge gears or shutters are not being engaged then either the right side cam, right slide lever, or Main Drive Assembly (MDA) should be examined.
Note to printer users: If you have read through the troubleshoot procedure and believe you have a lock lever and slide lever problem I would strongly recommend you call your service technician. Repair, especially on the right side, can be an extremely complicated procedure and requires the skills of a trained professional.
Removing the Lock Levers and Assemblies on the Left side
Pull up on the fuser to remove it from the printer.
5. Lift the upper cover to remove it.
Rear Upper Cover
Note: I’m not covering the right side cover because if you remove the formatter and release the tabs in the back right cover you can remove the rear upper cover without removing it.
3. Once the contact assembly is out the four lock levers, slide lever, and cam assembly are all exposed and easily removed.
Note: The black lock lever is different than the three colors so if you need to order all four make sure you are getting the correct part.
Right Side Cartridge Lever Replacement
1. Remove toner and transfer belt.
2. Remove top cover and disconnect purple wire.
3. Remove right side cover. Be careful not to lose the metal arm that connects to the power switch lever.
4. Remove interlock switch, unplug cable at drive PCA
Before Reinstalling the MDA
Make sure the toner cam gears are aligned properly before installing the main drive assembly.
- The four large gears should be in an approximate line.
- The top two large gears have an oval hole that aligns with a triangle stamped into the sheet metal.
- The two small gears to the right align with the three large bottom gears. Notice the two holes on each of the small gears align with the small holes of the large gears.
On the top and bottom shafts you can see a black plastic part that has a flag associated with it. The top flag is for the black cartridge. The bottom flag is for all the color cartridges.
Top flag Bottom flag
Also, note that the white cams are all at different degrees of rotation. This reduces the force required to drive the motors when turning the cams. Metal shafts should be oriented with the empty space downwards.
2. Turn theMDAover so the six white gears and four black cartridge drive gears are facing you. Have the two white gears on top and the four black cartridge gears on bottom. The four white posts on the cartridge gear assembly should all be moved clockwise to the right side of the cartridge gears for easy installation with the slide lever. Lines etched in the metal should help. The post should be sitting at around a 1 to 2 O’clock position.
3. The two white gears on top control the four white gears below them. The right gear controls the black cartridge gear and the left controls the three colors gears. Just to the right of the four gears are holes in the metal frame of theMDA. Holes in the gears inside the unit coincide with these holes in the frame. By rotating the two gears on top of the unit you can align the holes in the gears with the holes in the frame if they are not already aligned.
4. Carefully install theMDAback into the machine. When you get it installed you might want to manually lower and raise the white slide lever a few times to make sure it’s engaging the toner drive gears before you reinstall all the other parts.
Note: If you get everything put back in place and your prints come out with parts of the color missing, mis-aligned, or it makes a lot of noise, the toner cam gears are probably mis-aligned and disassembly will probably be needed.
Conclusion About the 10.92.YY Cartridge Not Engaged Error Message.
While this error can be easy to diagnose it can become a very complicated and frustrating repair. The main thing I can say here is to take your time and follow the instructions. Read through everything first so you know what you’re getting into. The first one I did I took theMDAapart resulting in purchasing another one and I didn’t know about the toner cam gears so I had to disassemble the machine again after my first repair to get them aligned correctly. It ended up taking a lot longer than what it should have. Hopefully with more articles out there like this one people will have better chances of getting it right the first time.
